METHOD FOR THE PRODUCTION OF ODOR-FREE CONDENSATION PRODUCTS FROM PHENOLS AND ISOBUTYRALDEHYDE BY CONDENSATION OF THE MENTIONED SUBSTANCES AND SUBSEQUENT WATER STEAM DISTILLATION

摘要

1. A process for the production of byproduct-free and odorless condensation products from phenols and isobutyraldehyde by reaction of the phenols with isobutyraldehyde at elevated temperature in a molar ratio of 0.5:1 to 1.5:1 in the presence of an acid or a compound hydrolyzable to an acid, as catalyst, subsequent neutralization and removal of the resulting reaction water by distillation, wherein the reaction products thus obtained are additionally subjected to a steam distillation.
