Product Description

Food Grade 3-Phenylpropionic acid with CAS No. 501-52-0

Product Overview

3-Phenylpropionic acid, it is white prismatic crystals. Its melting point is 48.5 ° C, its boiling point is 280 ° C, 125-129 ° C (0.8 kPa), its relative density is 1.071. Soluble in hot water, alcohol, benzene, chloroform, ether, glacial acetic acid, petroleum ether and carbon disulfide, slightly soluble in cold water. Can volatilize with water vapor. 3-Phenylpropionic acid is a flavoring agent for spices. It is used as a pharmaceutical intermediate, also used in organic synthesis and a perfume fixative. Using cinnamic acid as a raw material, 3-phenylpropionic acid can be obtained by the following two methods. (1) The cinnamic acid is mixed with a sodium hydroxide solution at 80-90 ° C to form a sodium salt, and after adding Raney nickel to the solution, add hydrazine hydrate gradually and dropwise. Cool to 20 ° C, add hydrochloric acid to make pH = 1, 3-phenylpropionic acid is precipitated then. (2) 2.5% amalgam was slowly added to the mixture of cinnamic acid and sodium hydroxide solution under stirring, and cinnamic acid was reduced to phenylpropionic acid by the produced nascent hydrogen. The reaction mixture is acidified with hydrochloric acid, and the phenylpropionic acid is precipitated as an oil and solidified quickly, and recrystallized from hot water to obtain a finished product.
