Bio-derived glycerides formed from a reaction between waste glycerol and biodegradable or bio-derived fatty acid esters such as crude biodiesel or soybean oil triglycerides are useful as dust suppressants, binders, and stabilizing agents.

Bio-derived composition for dust control

Bio-derived glycerides formed from a reaction between waste glycerol and biodegradable or bio-derived fatty acid esters such as crude biodiesel or soybean oil triglycerides are useful as dust suppressants.

The invention relates to a resin having a plurality of cyclic carbonate groups comprising the reaction product of: a) an epoxidized sucrose fatty acid ester resin, and b) carbon dioxide where a) and b) are reacted under conditions sufficient to carbonylate a plurality of the oxirane groups of the epoxidized sucrose fatty acid ester resin, and optionally in the presence of a catalyst or of a solvent. In one embodiment the epoxidized sucrose fatty acid ester resin is epoxidized sucrose soyate. The invention also relates to methods for producing a resin having a plurality of cyclic carbonate groups. In a method of the invention, an epoxidized sucrose fatty acid ester resin is contacted with carbon dioxide under conditions sufficient to carbonylate a plurality of the oxirane groups of the epoxidized sucrose fatty acid ester resin, and optionally in the presence of a catalyst or of a solvent. Other embodiments of the invention relate to curable composition containing a) a resin having a plurality of cyclic carbonate groups; b) an alkyl amine curing agent having two or more reactive amine groups; and c) optionally, a catalyst; and cured compositions and articles.
