Why Concentrated Sulfuric Acid Is Used In Esterification

Esterification is a relatively slow process at room temperature and does not proceed to completion. Concentrated sulfuric acid is used as a catalyst, and has a dual role: Speeds up the reaction. Acts as a dehydrating agent, forcing the equilibrium to the right and resulting in a greater yield of ester. 

Sulfuric acid is needed as a catalyst in an esterification reaction. Sulfuric acid provides the hydronium ions that protonate the carbonyl oxygen and make the carbonyl carbon a better electrophile. Even if you are using concentrated sulfuric acid, it contains 2 % water, so hydronium ions are present.

Sulfuric Acid For Laboratory Work And Chemical Analysis

Sulfuric Acid Grades

  • Lab chemicals, such as sulfuric acid, are labelled with a grade that designates a certain level of purity standards.
  • ACS grade sulfuric acid meets or exceeds purity standards set by the American Chemical Society (ACS).
  • USP grade sulfuric acid meets or exceeds requirements of the United States Pharmacopeia (USP). This grade of sulfuric acid is acceptable for food, drug or medicinal use.
  • HPLC grade sulfuric acid is manufactured specifically for use with HPLC instruments.
  • Analytical grade sulfuric acid designates that this reagent is suitable for use in analytical procedures.

Identification Of Sulfuric Acid

Sulfuric acid is a dense, oily liquid that can be colorless to brown, depending on the purity. It can also exist as ice- or fiber-like crystals or as a gas. Sulfuric acid is also called battery acid. It is odorless with a strong acid taste. Sulfuric acid reacts violently with water, generating much heat. It is highly corrosive. Read more here.

Sulfuric Acid | Structure, Formula, Uses, & Facts

Sulfuric acid, sulfuric also spelled sulphuric (H2SO4), also called oil of vitriol, or hydrogen sulfate, dense, colorless, oily, corrosive liquid; one of the most important of all chemicals, prepared industrially by the reaction of water with sulfur trioxide (see sulfur oxide), which in turn is made by chemical combination of sulfur dioxide and oxygen either by the contact process or the chamber process.

In various concentrations the acid is used in the manufacture of fertilizers, pigments, dyes, drugs, explosives, detergents, and inorganic salts and acids, as well as in petroleum refining and metallurgical processes.

In one of its most familiar applications, sulfuric acid serves as the electrolyte in lead–acid storage batteries. Pure sulfuric acid has a specific gravity of 1.830 at 25 °C (77 °F); it freezes at 10.37 °C (50.7 °F).

When heated, the pure acid partially decomposes into water and sulfur trioxide; the latter escapes as a vapour until the concentration of the acid falls to 98.3 percent. This mixture of sulfuric acid and water boils at a constant temperature of 338 °C (640 °F) at one atmosphere pressure. Sulfuric acid is commonly supplied at concentrations of 78, 93, or 98 percent.

Sulfuric acid is a very strong acid; in aqueous solutions it ionizes completely to form hydronium ions (H3O+) and hydrogen sulfate ions (HSO4−). In dilute solutions the hydrogen sulfate ions also dissociate, forming more hydronium ions and sulfate ions (SO42−).

In addition to being an oxidizing agent, reacting readily at high temperatures with many metals, carbon, sulfur, and other substances, concentrated sulfuric acid is also a strong dehydrating agent, combining violently with water; in this capacity, it chars many organic materials, such as wood, paper, or sugar, leaving a carbonaceous residue.

The term fuming sulfuric acid, or oleum, is applied to solutions of sulfur trioxide in 100 percent sulfuric acid; these solutions, commonly containing 20, 40, or 65 percent sulfur trioxide, are used for the preparation of organic chemicals. Read more here.

What To Do In Case Of A Sulfuric Acid Spill In Your Laboratory 

Sulfuric Acid Spills And Exposure

If sulfuric acid is spilled or leaks and gets on your skin, quickly flush your skin with soap and lukewarm water for at least 30 minutes. Do not scrub or rub skin. If strong concentrations of gas or solution penetrate clothing, remove clothing and flush the skin with water. Seek medical attention immediately.

Immediately report leaks, spills or failures of the safety equipment (e.g. ventilation system). Prevent accidental contact with incompatible chemicals.

Sulfuric acid spills should be neutralized with sodium bicarbonate and then cleaned up with a paper towel or sponge.

  • Neutralize spill with sodium bicarbonate/baking soda

  • Wait until bubbling/fizzing has stopped

  • When using a neutralizing spill kit, the kits are buffered and will not have a bubbling action. Be careful not to over-neutralize

  • Test pH of the spill after the neutralization reaction has stopped with pH paper

  • Once pH is between 6 and 9, the material can be transferred into an appropriate secondary container for disposal

  • Wipe all surfaces with a sponge and wash all of the material down the sink.

Sulfuric Acid Chemical Properties, Hazards And Uses

Information About Sulfuric Acid From Wikipedia

Sulfuric acid (alternative spelling sulphuric acid), also known as vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with molecular formula H2SO4.

It is a colorless, odorless, and viscous liquid that is soluble in water and is synthesized in reactions that are highly exothermic.

Its corrosiveness can be mainly ascribed to its strong acidic nature, and, if at a high concentration, its dehydrating and oxidizing properties.

It is also hygroscopic, readily absorbing water vapor from the air. Upon contact, sulfuric acid can cause severe chemical burns and even secondary thermal burns; it is very dangerous even at lower concentrations. 

Sulfuric acid is a very important commodity chemical, and a nation's sulfuric acid production is a good indicator of its industrial strength.

It is widely produced with different methods, such as contact process, wet sulfuric acid process, lead chamber process and some other methods.

Sulfuric acid is also a key substance in the chemical industry. It is most commonly used in fertilizer manufacture, but is also important in mineral processing, oil refining, wastewater processing, and chemical synthesis.

It has a wide range of end applications including in domestic acidic drain cleaners, as an electrolyte in lead-acid batteries, in dehydrating a compound, and in various cleaning agents. Read more here.
