Abstract:
A catalyst prepared by polymerizing 0-98 weight % butylstyrene; 0-80 weight % vinyl toluene; 1.5-25 weight % divinyl benzene having 1-98 weight % of ethyl vinyl benzene; and 0-80 weight % styrene. Copolymer beads are made, sulfonated, and used as a catalyst.
Abstract:
The present invention relates to the treatment of a promoted strong acid ion exchange resin for use as an acid catalyst with an antioxidant to protect the resin from oxidative degradation and the use of said treated promoted ion exchange resin catalyst in chemical production processes.

Abstract:
A continuous process and system for preparing branched aldehydes by reacting aldehyde with an acid polymeric catalyst absent any metal from Group VIII to produce a product having about 10 to 99.99% by weight branched unsaturated aldehyde and at least 92% selectivity of reaction to the branched aldehyde and recycling a portion of the product.
