PCT No. PCT/EP92/00932 Sec. 371 Date Nov. 4, 1993 Sec. 102(e) Date Nov. 4, 1993 PCT Filed Apr. 29, 1992 PCT Pub. No. WO92/19577 PCT Pub. Date Nov. 12, 1992.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.
