Abstract
A process for the production of epoxide ring opening products having a defined residual epoxide oxygen content by reaction of epoxides with nucleophiles in the presence of medium-strength acids is provided. The products have a defined residual epoxide oxygen content of 10 to 80% by weight based on the epoxide. In the process, aliphatic epoxidized olefins or aliphatic epoxidized esters are reacted with nucleophiles in the presence of 1 to 4 g phosphoric acid, phosphorous acid, or hypophosphorous acid per mol epoxide and the ring opening product is directly obtained without neutralization of the catalyst acid.
