Purification of erucic acid by low‐temperature crystallization

Abstract

Abstract Purification of crucic acid for laboratory use by low‐temperature crystallization from aqueous acetone, ethanol, and methanol has been investigated. Two crystallizations of technical grade commercial acid (76舑86%) from acetone‐water (5蝘1) provided products of 94舑98% purity, depending on the original composition; residual impurities were primarily C 20 monoene and C 22 saturated acids.
