Chemical Properties
2,2,2-Trichloro-1-phenylethyl acetate forms white crystals (mp 88 °C) and has a weak, very
natural, lasting rose odor.
The ester is prepared from -trichloromethylbenzyl alcohol, for example,
by reaction with acetic anhydride. The alcohol can be prepared by one of the
following methods:
1) Addition of trichloroacetaldehyde (chloral) to benzene in the presence of aluminum
chloride.
2) Reaction of benzaldehyde with chloroform in the presence of potassium
hydroxide.
-Trichloromethylbenzyl acetate is a stable rose fragrancewith excellent fixative
properties. It is preferentially used in soaps, powders, and bath salts.
Occurrence
Has apparently not been reported to occur in nature.
Uses
Perfumes, fixative for essential oils and perfumes.
Definition
ChEBI: Alpha-Trichloromethylbenzyl acetate is a carboxylic ester. It is functionally related to a benzyl alcohol.
Preparation
By the reaction of benzene and chloral, in the presence of a catalyst, followed by acetylation.
Flammability and Explosibility
Non flammable
Trade name
Rosalin (Yinghai)
Safety Profile
Mildly toxic by ingestion. A skinirritant. When heated to decomposition it emits toxicfumes of Clí.
Solubility in organics
Insoluble in water, somewhat soluble in
alcohol, soluble in most perfume oils. The
volubility in cold alcohol is sufficient for
perfume composition purposes, but not to
have a concentrated solution of the material
on hand.
