A method of production of value-added, biobased chemicals and derivative products from bioglycerin is described herein. The present method provides methods for desalinating, decolorizing, and concentrating bioglycerin for the production of biobased chemicals, derivative products, and/or purified bioglycerin.

Method of biobased chemical production from crude bioglycerin

There is provided a method for manufacture of 2-oxoimidazolidines of Formula I comprising one or more of the steps of converting an amine to an acylation agent, condensation of the acylation agent with a bi-functional compound of structure L-C(R)(R)&#x2014;C(R)(R)&#x2014;NHR, wherein L is a leaving group, and ring closure of the resulting urea. In this manner, certain 2-oxoimidazolidines may be manufactured that are useful intermediates for the production of Pramiconazole and structurally related compounds. 

Method for manufacture of 2-oxoimidazolidines

There is provided a process for manufacture of optically-active, 2-(acyloxymethyl)-1,3-oxathiolanes of Formula I comprising a preparation of a racemic compound and an enzyme-catalyzed kinetic resolution of the enantiomers. The invention may further provide for the esterification and racemization of the by-product of the enzymatic reaction. In this manner, 2(R)-(benzoyloxymethyl)-1,3-oxathiolane is prepared as a useful intermediate for manufacture of the anti-HIV drug Apricitabine.
