Abstract: Disclosed is a process for the preparation of emulsifiers E1 which are obtained by (a) reacting a polyol with propylene oxide or a mixture of ethylene oxide and propylene oxide, to give an intermediate Z1, (b) reacting the intermediate Z1 with epichlorohydrin, forming an intermediate Z2, (c) reacting the intermediate Z2 with an adduct of ethylene oxide or a mixture of ethylene oxide and propylene oxide, with a C1-C22 monoalcohol, provided that on average at least one epoxide function of the intermediate Z2 is reacted and on average at least one epoxide function originating from the intermediate Z2 is retained. Compounds E1 are suitable as emulsifiers for preparing aqueous emulsions or dispersions of epoxy resins.

Abstract: Novel mixtures of long-chain (C10-C20) olefins are functionalized by conversion to aldehydes using an OXO process, or to sulfates, sulfonates, sulfones, sulfides, or sulfoxides by direct sulfonation. The aldehydes may then be hydrogenated to form alcohols, or aminated to form amines or amides. The olefins starting mixture may be acquired as a byproduct of the tetramerization of ethylene in the presence of certain chromium-containing tetramerization catalysts. The functionalized mixtures, and derivatives prepared therefrom such as alkoxylates prepared from the alcohols, may be useful as surfactants that may offer improved performance in many applications, while their preparation based on a byproduct mixture reduces their cost and also reduces waste-handling issues for this non-targeted stream.
