Urea adducts of the esters of stearic acid

<p>Urea forms crystalline complexes with n-alkanes and their liner derivatives but not with most branched and cyclic hydrocarbons and their derivatives. The compounds are stable enough to be used in separating these types of aliphatic compounds from their branched and cyclic analogs. Linear esters derived from normal saturated acids give adducts as expected. Urea complexation was found to be of great importance in the purification and separation of unsaturated esters of high molecular weight.</p><p>The object of the present research was to investigate the compositions of urea adducts of various long-chain esters, approaching the class of waxes, to test various methods of determining their compositions, and to determine the suitability of the adduct method for purifying such esters.</p>
