BUTYL LACTATE is an ester. 
Esters react with acids to liberate heat along with alcohols and acids. 
Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. 
Heat is also generated by the interaction of esters with caustic solutions. 
Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. 

Butyl lactate is the butyl ester of the lactic acid. 
Its scent is characteristic and Butyl lactate is partially mixable with water and most organic solvents. 

N-Butyl lactate is typically encountered as a solvent for processing cellulose derivatives, natural gums, oils, dyes, paints and polymers. 

Butyl lactate is a kind of lactate derived ester.
As a kind of alpha-hydroxy acid ester, Butyl lactates applications in cosmetic, food and pharmaceutical formulations have significantly increased due to their hygroscopic, emulsifying and exfoliating properties. 
Butyl lactate is used as a food additive because of its flavoring effect. 
In industry, Butyl lactate can be used as solvent and chemical feedstock. 
As a bio-based solvent, Butyl lactate can be used as extractant for removing 1-butanol from the aqueous fermentation broths. 
Butyl lactate can be generally manufactured through the action of lipase from various origins.

n-Butyl lactate is used as a food and feed additive.

Butyl lactate has a faintly sweet, pleasant odor with buttery, creamy, milky, sweet, mushroom undertones. 
Two optically active and one racemic form of butyl lactate are known.

Butyl Lactate is an alkyl ester of lactic acid. 
Butyl lactate is formed by the reaction of lactic acid with 1-butanol.

Butyl lactate is colorless stable liquid, mild smell. 
Butyl lactate can be hydrolyze in the presence of acid and alkali but not bibulous, it used for nitrocellulose lacquer,printing ink, natural and synthetic resin and other solvents. 
Butyl lactate is also used to dry lotion, adhesives prevent skinning agent and spices, etc. 
For high boiling point solvents, butyl lactate used in the natural resin, synthetic resin, paint, printing ink. 

Preparation:
The racemic d-form is prepared by reacting zinc ammonium l-lactate with n-butyl alcohol in the presence of concentrated H2SO4; the l-form is prepared by reacting zinc ammonium d-lactate with n-butyl alcohol in the presence of HCl; the racemic form is prepared by several methods, one being from calcium or sodium lactate and n-butyl alcohol in benzene in the presence of H2SO4, with subsequent azeotropic distillation of the mixture.
