APPLICATIONS OF BIOBASED GLYCOL COMPOSITIONS

A biobased replacement for propylene glycol and ethylene glycol derived from petrochemical sources is presented. The product mixture from the hydrogenolysis of certain polyols from biobased renewable resources may replace propylene glycol and ethylene glycol products from petrochemical sources. Applications and methods of the biobased hydrogenolysis product mixture are disclosed. The compositions and methods provide a feedstock for industrial use which has a 13C/12C isotope ratio characteristic of bioderived material.

Direct epoxidation process

A process is disclosed for reacting an olefin, hydrogen, and oxygen in a reactor in the presence of a catalyst comprising a transition metal zeolite and a noble metal to produce a reaction mixture comprising an epoxide and acidic byproducts. A portion of the reaction mixture is contacted with an adsorbent so that a treated mixture having a reduced amount of byproducts is produced. The treated mixture is recycled back to the reactor. Including an adsorption step should improve the catalyst productivity and epoxide selectivity.
