Butyl Acetate

Butyl acetate, or urethane class, is an organic ester compound with the molecular formula C4 H8 O2. This composition is neutral and colorless. This chemical is included in the category of organic solvents. It has a sweet smell similar to the smell of fruit. It has low water solubility, low viscosity, flammable and volatile. This product has many applications in various industries. It is often used to dilute other chemicals.

Butyl acetate has many uses in various industries. It is often used to dilute other chemicals. It is worth noting that this chemical substance can be produced in two different ways. If it has a purity of more than 99 percent and some parameters specified in the continuation of the article. Butyl acetate is referred to as the polyurethane class.

USES OF BUTYL ACETATE

Butyl acetate is one of the most important solvents with good volatility due to its high solubility and high dilution capacity. This solution has many uses. Among its most important applications, it is included as a solvent in the field of Decking and paint production.

Butyl acetate is a suitable solvent for a wide range of surface coatings, including epoxies, urethanes, celluloses, acrylics and vinyls. The main Sunday of these surface coatings is the wood industry, containers, bodywork and marine applications.

This product is used in various sectors such as stain remover, colored paper, perfume, fruit flavors and essential oils, leather and artificial textures, thinner production. It is also found in cosmetics, skin care and nail polish removers.

This product is a very suitable solvent for the production of varnish resins and other raw materials for varnishes. As a result, it is used as a solvent in the production of varnishes and paints. Also, this chemical solvent is used in large quantities in compound varnishes; it can be used to disperse the isocyanate component in polyurethane varnishes.

Some other uses of butyl acetate are as follows.

Production of varnish, artificial leather, photographic film, plastic and safety glass.
This compound can be used in candy, ice cream, baked goods, cheese, yogurt, etc. it is used as an artificial sweetener in the food industry.
Production of nail cleaners and other nail care products.
Add it to the diesel engine to prevent damage to the vehicle engine.
BUTYL ACETATE PRODUCTION PROCESS

The production method of butyl acetate is the esterification of butanol. Esterification is a reversible reaction between an alcohol and an organic acid (acetic acid) in the presence of a strong inorganic acid such as sulfuric acid, which produces a compound called an ester and is accompanied by water production. Decontamination is a reversible reaction between an alcohol and an organic acid (acetic acid).

Butyl acetate is produced in the same way from the normal reaction of butanol and acetic acid.

C2H5OH+CH3COOH=>CH3COOC2H5

+H2o

First, butanol and acetic acid are given to the reaction, and then sulfuric acid is added in an amount of one percent of the weight as a catalyst. Due to the endothermic (heat field) nature of the esterification reaction, this reaction begins due to heat and continues until the temperature is constant throughout the distillation tower and a uniform state is formed. Therefore, the feedstock input flow to the reactor should be adjusted according to the distillation speed in the tower. After this stage is completed, water is decomposed from urbutylene butyl acetate, and the percentage of butyl acetate obtained from this stage by weight is about 83, and contains catalyst and residual alcohol. For the purification of butyl acetate, it is first neutralized with sodium carbonate in a neutralization tank and then washed with water.

After the two-phase liquid is formed, water is drained from the lower part. The top layer of this product, which is itself, is transferred to the distillation tower to increase purity. The treated product is taken from under the tower and transferred to the storage tank.

SECURITY ISSUES
THE EFFECT OF BUTYL ACETATE ON HEALTH AND BASIC FIRST AID

In case of eye contact, wash immediately with plenty of cold water for at least 10 minutes. See a doctor to get the necessary medical care.

If butyl acetate comes into contact with the skin, first wash the skin with plenty of cold water and soap. Next, apply an emollient cream to the irritated part of the skin. If skin irritation persists, definitely consult a doctor.

If butyl acetate is inhaled, immediately remove the affected person to fresh air Jul. If breathing stops, perform CPR. If there are breathing difficulties, give artificial oxygen. In case of ingestion of this chemical solvent, do not force the affected person to vomit. Do not feed the person anything. Tie, vest, necklaces, belt, etc. open it to make him breathe better and consult a doctor.

IGNITION AND EXPLOSION INFORMATION

Due to its high volatility and other chemical properties, butyl acetate is highly flammable. So much so that there is a possibility of fire or explosion due to a very small spark, flame and even heat. Therefore, it is very important to comply with safety measures in the storage of butyl acetate. Use dry chemical powder for small fires, alcohol foam, water or gas for large fires.

MAINTENANCE AND STORAGE METHODS

Due to the high flammability and volatility of butyl acetate, it is recommended to store this chemical solvent in a separate and approved area away from flammable and hazardous substances in open environments.

If the internal storage space is used, the container containing this material should be completely sealed and stored in a dry, cool and well-ventilated environment. Close the lid of the container containing this chemical well until it is used again. Prevent any fire source (such as sparks and flames) from reaching this material.

In case of leakage of this product, first dry the leaked material with dry soil, sand or a non-flammable material. Prevent leaks from entering sewers, basements or enclosed areas. If necessary, make a bent to stop the leak.
