Butyl benzoate Chemical Properties,Usage,Production

Chemical Properties

Butyl benzoate is a clear yellowish oily liquid or colorless viscous liquid. Insoluble in water,  poorly soluble in Propylene glycol, soluble in alcohol, 95% ethanol and oil, with sweet and soft with astringent floral and paste fragrance, very light ambergris scent, woody and spicy underlying fragrance. The aroma is weak and lingers long. B.P. 250℃. Sp.Gr. 1.01.

Application

Butyl benzoate has been used as:
preservative in commercial cosmetic lotions
as involatile solvent, for sampling of isocyanates with silica gel solid phase extraction

Uses

Butyl benzoate is used as a solvent for cellulose ether, a dye carrier for textiles, and a perfume ingredient . It occurs naturally as a volatile component of various fruits and vegetables. It has been approved by the FDA as an indirect food additive for use as a component of adhesives.

Production Methods

Butyl benzoate is formed by the direct esterification of n-butyl alcohol with benzoic acid under azeotropic conditions .

Definition

ChEBI: Butyl benzoate is a benzoate ester obtained by condensation of benzoic acid and butanol. It is used as a perfume ingredient and as a solvent for cellulose ether, a dye carrier for textiles. It has a role as an antimicrobial food preservative, a fragrance and a plant metabolite.
