DL-Mandelic acid Chemical Properties,Uses,Production
Chemical Properties
Mandelic acid turns brown when exposed to light. It can be esterified easily with alcohols in the presence of hydrogen chloride.
Physical properties
(R,S)-Mandelic acid (a-hydroxyphenylacetic acid, phenylglycolic acid), C6H5CH(OH)COOH, C8H8O3, Mr 152.15, mp 118 – 121℃, is a colorless crystalline powder. It is readily soluble in ethanol and diethyl ether, less soluble in chloroform, and insoluble in petroleum ether. Its water solubility is 15 g per 100 mL of water. In alkaline solution, mandelic acid dissolves to form salts.
Production Methods
(R,S)-mandelic acid is produced by hydrolysis of mandelic acid nitrile [532-28-5] (mp 10℃) with hydrochloric acid. Mandelic acid nitrile is obtained by the conversion of benzaldehyde [100-52-7] and hydrogen cyanide in the nascent state (NaCN + HCl) under refrigeration. Another method of producing mandelic acid is the hydrolysis of a,a-dichloroacetophenone with alkali.
