Process for the preparation of 1-arylpropane-1,3-diol diacylates.

摘要

1. Process for preparation of 1-arylpropanediol-1,3-diacylates by reaction of arylolefines with carboxylic acids and/or their anhydrides and with formaldehyde in the presence of acids, characterized in that, the arylolefine, carboxylic acids and/or their anhydrides and formaldehyde are used in molar ratios of 1 : 2 to 10 : 0.5 to 2, and 0.1 to 1 Mol 4-aryl-1,3-dioxane/Mol arylolefine is added to the reaction mixture and reacted at temperatures of 10 to 50 degrees C.
