Abstract:
1. A method of synthesizing glycerol-based surface active products in a continuous process under a low reactivity atmospheric environment, comprising the steps of: a) reacting a reaction mass comprising at least glycerol monomer in the presence of a strong base catalyst of a concentration of above 2% at a temperature above 200 degrees C. which produces a first product comprising polyols which are both branched and cyclic, and a co-product comprising lactic acid, lactic salt, and any combination thereof, b) esterifying the first product in presence of an acid catalyst of a concentration above 5% at a temperature above 115 degrees C. to produce a second product, and c) alkylating the second product at a temperature above 115 degrees C. to form a third product, and d) crosslinking the third product at a temperature above 1.15 degrees C. to form an end product.
