Abstract: The present invention relates to a method for producing 1-hydroxymethyl-1,2-diphenyloxiranes from 2,3-diphenylpropenals by means of epoxidation and reduction. The formation of objectionable by-products can be suppressed in that the reduction is started before the 2,3-5 diphenylpropenal is completely converted. The hydroxymethyl diphenyloxiranes represent valuable intermediate products for producing 1-azolylmethyl-1,2-diphenyloxiranes, wherein the latter can be easily produced from said intermediate products by introducing the azolyl group.

Abstract: Flavan-based and spirodichroman compound-based phosphate esters prepared by reacting flavans and spirodichroman compounds with phosphorus oxychloride, monophenyl dichlorophosphate, or diphenyl chlorophosphate compounds are described. The flavans and spirodichroman compounds can be synthesized by the reaction of resorcinol with aliphatic acetone. Such phosphate esters can be used as flame retardants.

Abstract: This invention relates to a method for the purification of glycidyl acrylate or glycidyl methacrylate. Specifically, the invention effects the purification by using a residual catalyst-inactivating additive and consequently produces highly purified glycidyl acrylate or glycidyl methacrylate containing substantially no epichlorohydrin and having a low chlorine content.
Abstract: The hydrolyzable halide content of glycidyl ethers prepared by dehydrohalogenating a halohydrin ether intermediate product in the presence of an organic solvent, washing the resultant product with water and distilling the solvent from the organic phase from the water wash step is stabilized when the distillation step is conducted in the presence of a sulfonic acid, sulfonic acid ester, organic sulfate or any combination thereof such as p-toluene sulfonate.
