How 200 Proof Ethanol Completely Denatured With Heptane Is Used In U.S. Botanical Industries
Ethanol denatured with heptane is a high purity extraction grade. Ethanol and n-heptane are non-polar solvents. This extraction solvent is ideal the production of "crude botanical extracts". Crude extract is an unprocessed material that must be refined by Botanical processors to produce final products sold todispensariesand consumers. Crude extracts are produced using ethanol extraction or CO2 extraction. End products such as vape pens and edibles have varying extraction requirements. Note that heptane should be purged from final Botanical products and crude botanical extracts.
n-Heptane is a paint solvent and rubber cement thinner. Lab Alley sells a high purity (99.9%) grade of n-heptane. Heptane is widely usedin laboratories in the United States as anon-polar solvent. In someBotanical processing labs, heptane is used to replacehexane. Heptane and methanol are often used for botanical wax extractions. Althoughethanolis the most common solvent used inlarge scaleBotanical extraction and processing operations, hexane and heptane are also used at these facilities. Organic non-polar solvents such hexane are used toextract non-polar compoundsfrom plant materials.
Heptane, ethanol and hexane are used by industrial hemp extraction facilities and hemp processing facilities in the USA. Some Botanical extraction equipment used at these facilities are compatible with ethanol, heptane and hexane. Heptane in 55 gallon drumsare sold online by Lab Alley and are used by large scale industrial agri-processing facilities. Some botanical processing facilities use Centrifugal Partition Chromatography and heptane to manufacture pure botanical products.
Lab Alley sells heptane (n-heptane), a widely utilized nonpolar solvent in manufacturing and laboratories. Heptane is slightly less volatile and hazardous than hexane, making it more popular for many processes requiring a solvent.
Common Uses and Benefits of Heptane in the United States in 2019
There are several grades of Heptane sold by Lab Alley. Heptane is astraight-chain alkane, and it has seven carbon atoms. n-Heptane is colorless, insoluble in water and is less dense than water. It has a low boiling point and a low toxicity. It is used often in gasoline, because it provides the anti-knocking quality in a fuel. The knock occurs when theoctane requirementof the engine exceeds the octane quality of the fuel. Heptane is commonly used in labs for organic synthesis. It is also used as a reagent and as a solvent. Heptane is used in various industrial ways as well. For example, one common use is in printer ink. It helps contribute to the final product seeming smooth and long lasting. Heptane is also used in the botanical industry, much likehexane, heptane is often the preferred solvent because it is cleaner and cheaper. Lab Alley sells Heptane solutions in various grades to individuals and businesses online in the USA.
Grades of Heptane (n-heptane) Include ACS Reagent, Laboratory Grade and Ethanol Denatured with Heptane
There are seven different types of grades for heptane. It is important to be familiar with their impact on different products and understand what degree of purity is required based on the intended use. ACS grade is acceptable for food, drug, or medical use. It can be used for situations that require stringent quality specifications and a purity equal to or greater than 95%. Reagent grade is usually equal to ACS grade, it is used for food, drug, or medical use. It is also accepted to be used in laboratory and analytical applications. USP grade meets the requirements of theUnited States Pharmacopeia. This grade is also accepted for food, drug, or medical use. Unlike the ACS grade, it is only used for laboratory purposes. NF grade meets the requirements of theNational Formulary. The USP and the NF jointly published a book for pharmacopeia standards for drug substances, dosage forms, compounded preparations. To find the proper grades the book should be reviewed.
Laboratory grade is popular in educational settings. In this grade the levels of impurities are unknown, and it is not pure enough to be used in food, drug, or medical use. It is accepted to be used for teaching and training. Purified grade meets no official standard. It is also not pure enough to be used in food, drug, or medical use. Technical grade is used for commercial and industrial purposes. But it is also not accepted to be used in food, drug, or medical use. Theethanol denatured with heptanesold by Lab Alley is commonly used in the botanical extraction industry. Instead of usingpure ethanol, ethanol denatured with heptane is a close equivalent. People that switch often find the same or sometimes better yields. It does require a slight change in procedure and process. Heptane has a higher boiling point compared to ethanol. This means that it may be necessary to heat the oil to a higher temperature or increase distillation times to remove the heptane completely.
Heptane Use in the Botanical Processing and Extraction Industry in the U.S.
Heptane is used in the USA to dissolve or remove waxes/ lipids during theextraction process. Because heptane is nonpolar it is a good solvent for extraction. Heptane’s boiling point is around 209°F, so it is important to properly purge the heptane before consumption. When processing botanical extract the first step is to dry it out and then soak it in the solvent until it dissolves. Then the botanical extract can be collected from the solvent. Next is thepurging process, because hexane is not pressurized the purging process may take longer than usingethanol denatured with hexane. But using heptane as a solvent has its benefits. It creates a more potent and flavorful botanical oil. Lab Alley provides fast shipping in the USA. You can orderheptane forbotanical processing facilitiesin a 55 gallon drum for $900. Heptane is also used to remove botanical resin concentrates, as a "wash" forbutane hash oil/butane honey oil(BHO) products and for recrystallization processes.
Butane Hash Oil, or BHO, is a botanical concentrate (extract) produced using butane as a solvent. Because of its effectiveness, pricing over CO2 extraction and purity -butane hash oil extractionis a popular process for manufacturing botanical concentrates in the United States. Consumers in the USA purchase vape pens that contain botanical concentrates which are evaporated during the inhalation process.
Heptane Selling and Shipping Regulations in America
Heptane is regulated by the department of transportation, OHSA, and it is cited by many other organizations. It is highlyflammable, and it is on the special hazard list. When transferring material, it is important to keep containers ground and bound. Use spark proof tools and explosion proof equipment. Store heptane in a tightly closed container. It should be stored in a cool, dry, well-ventilated area away from incompatible substances. TheDepartment of Transportation(DOT) has important information regarding the transportation of heptane. The United States Postal Service classifieshazardous materialsas any article or substance by the DOT as being capable of posing an unreasonable risk to health, safety, or property during transportation. Heptane falls under aclass 3because it is a flammable and combustible liquid. All flammable liquids are prohibited through domestic mail air transportation. But if the package is using surface transportation and going through domestic mail, the flammable liquids are allowed if it isORM-D material per 342.
Heptane is a clear, colorless liquid and it has a mild gasoline odor. It should not be swallowed for any reason. If it is swallowed it will cause anaspiration hazard. It is a flammable liquid and vapor. If it enters the lungs it can cause damage. Breathing the vapors can cause drowsiness and dizziness. It will also cause eye, skin, and respiratory tract irritation. Prolonged or repeated skin contact can cause dermatitis. N-heptane can cause a loss of appetite or nausea. It may also affect the nervous system.
Wash everything thoroughly after handling. Remove contaminated clothing and wash before reuse. Avoid contact with eyes, skin, and clothing. Containers that housed n-heptane in them will retain product residue as either a liquid or a vapor. It is important to keep away from heat and use in a well-ventilated area. Keep away from sparks and flames.
Facilities using heptane should be equipped with an eye wash station and safety shower. Heptane is stable under normal temperatures and pressures. Avoid using heptane in confined spaces. Heptane has an odor threshold of230 ppm. In the workplace OSHA states the legal airborne permissible exposure limit is 500 ppm average over an 8-hour work shift.
A tincture is typically an extract of plant or animal material dissolved inethanol (ethyl alcohol). Solvent concentrations of 25–60% are common, but may run as high as 90%. In chemistry, a tincture is a solution that has ethanol as its solvent. In herbal medicine, alcoholic tinctures are made with various ethanol concentrations, 20% being the most common.
Other solvents for producing tinctures include vinegar,glycerol(also calledglycerin),diethyl etherandpropylene glycol, not all of which can be used for internal consumption. Ethanol has the advantage of being an excellent solvent for both acidic and basic (alkaline) constituents. A tincture using glycerine is called a glycerite. Glycerine is generally a poorer solvent than ethanol. Vinegar, being acidic, is a better solvent for obtaining alkaloids but a poorer solvent for acidic components. For individuals who choose not to ingest alcohol, non-alcoholic extracts offer an alternative for preparations meant to be taken internally.
An extract is a substance made by extracting a part of a raw material, often by using a solvent such as ethanol or water. Extracts may be sold as tinctures, absolutes or in powder form. The aromatic principles of many spices, nuts, herbs, fruits, etc., and some flowers, are marketed as extracts, among the best known of true extracts being almond, cinnamon, cloves, ginger, lemon, nutmeg, orange, peppermint, pistachio, rose, spearmint, vanilla, violet, rum, and wintergreen.
A plant extract is a substance or an active with desirable properties that is removed from the tissue of a plant, usually by treating it with a solvent, to be used for a particular purpose. Extracts may be used in various sectors of activities : Food and functional properties for foodstuffs (antioxidant, texturizer, etc…), Processing aids, additives – chemical replacers, pharmaceutical for therapeutic properties - preventive and/or curative – cosmetic for functional properties for beauty and well-being, etc.
