Butyl Acetate - an overview | Science Topics
Difference between butyl acetate and n-butyl acetate
chemical butyl acetate is an organic compound with CTCT of C6H12O2 (CH3COOCH2CH2CH2CH3) . Also known under some other names such as butyl acetate, Butyl Acetic Ester, BAC, BA, Acetic Acid. Butyl acetate can mainly be used as a solvent for the manufacture of paints, printing inks, rubber, adhesives, .
Because the special smell resembles the aroma of ripe bananas, so in life, we often know this chemical by the name of gasoline or banana oil.
The isomers are Isobutyl acetate, tert-butyl acetate and sec-butyl acetate. We can easily find butyl acetate in many fruits.
this butyl acetate banana oil is highly flammable with a flash point of 24 °C.
is butyl acetate soluble in water?
It is very miscible with most common organic solvents (alcohol, acetone, aldehydes, aromatic hydrocarbons and aliphatic hydrocarbons but poorly soluble in water.
some uses of solvents butyl acetate
banana oil butyl acetate has a number of uses including as food flavoring, manufacturing industrial banana oil.
as solvent in the phase mix lacquer, in polishes, printing inks, adhesives.
butyl acetate is commonly used as a polar solvent has a moderate polarity. As an ingredient in paints, nail polish removers instead of ethyl acetate and acetone.
some of its other uses includes chemical cosmetic industries, fragrance solvents in perfumery. Acts as an anti-corrosion agent, in cleansing agents and care car.
Uses of n-butyl acetate solvent?
solvent n-butyl acetate has many uses in many industries. Industries uses it as the main components part including paints/lacquers, coatings, cosmetics, leather, cleaning and pharmaceutical industry grades.
Its solvent strength is similar to that of isobutyl acetate and methyl isobutyl ketone, and it is suitable as a substitute for these chemicals in many industries.
The role of n-butyl acetate in Industrial production of leather fabrics, artificial leather fabrics:
butyl acetate chemical is most commonly used in the paint distribution industry because its volatility is very convenient for applications to prevent paint clouding and cause an orange effect to the paint layer. Helps to dry the paint quickly while making the paint film even, sealed and good gloss.
must be careful not to use butyl acetate solvent on paints with free OH group such as urethane paint because butyl acetate will affect the quality of paint.
Due to its excellent property of dissolving cellulose nitrate, resins, polymers, oils and fats, butyl acetate is considered as an equally effective solution, especially in production management units such as: : House paint, lacquer, plastic, ink, glue, …
Safety of butyl acetate solvent
Environmental factors are increasingly concerned by countries around the world, so limiting and reducing the use of chemicals with highly toxic and harmful to the environment such as hexane, trichloromethane groups .vv Instead, such as toluene, xylene, and ketones are common in the chemical industry. And butyl acetate is the ideal replacement with preeminent properties, more affordable cost than previous substances, less harmful in the process of use.
not only that butyl acetate is also harmonized with N-butanol to increase the resistance to turbidity of other compounds. nImprove dissolving properties in most cases, and reduce solution consistency. .
Application of butyl acetate in pharmaceutical industry
the pharmaceutical industry also commonly uses butyl acetate in the supply of penicillin because of its excellent osmolarity retention and this chemical has become an ingredient to aid in drug absorption.
Due to its good water absorption and high resistance to hydrolysis, n-Butyl can also be used as an extractant in the distribution of pharmaceutical preparations.
Its other major use is to harden adhesives and coatings. This organic compound is also used in the pharmaceutical industry as a solvent or an extractant.
Synthesis of aromatic butyl acetate
most ways to preparation of banana oil butyl acetate commercially is by esterification of butanol and acetic acid. It is then heated with a catalyst such as sulfuric acid.
Preparation reaction butyl acetate with H2SO4 as a catalyst
The case when 1 isomer of butanol is used to substitute, you will also form an isomer of butyl acetate.
There are 2 main types of butyl acetate chemicals on the market today they are:
1. Butyl acetate aromatic solvent for industrial use:
2. lab-grade butyl acetate pure chemicals
Processing, storing, and loading
butyl acetate carries a number of different warnings and hazard properties. Therefore, extreme caution and precautions must be taken during handling and supply.
Risk and toxicity
butyl acetate is classified as highly flammable (NFPA rating of 3) and does not react with air and water. It can be conveniently ignited by high temperature and flame. Its relative is also heavy and will go to the ignition source and form an explosive mixture with air.
It also has an NFPA health rating of 2. Minimize inhalation as this will cause headache, drowsiness, mouth and eye irritation, and nausea.
It is necessary to use a PPE device for both eyes and skin as this will help limit long-term exposure to butyl acetate as it can cause dryness.
