Abstract

NEW MATERIAL:The carboxylate of a partially hydrogenated (alkyl)cyclopentadiene and its derivative, I and II (R1WR7 are H or 1W5C alkyl; R is H or alkyl), etc.
USE: It has properties similar to those of natural rosins. The carboxylic acid is useful as a thickening agent for synthetic rubbers, etc., an alkali metal salt of the carboxylic acid as an emulsifier for emulsion polymerization or a sizing agent for paper manufacture, and pentaerythritol ester, etc. of the carboxylic acid as a resin for coatings or adhesives.
PROCESS: The trimer or the tetramer of cyclopentadiene (or dicyclopentadiene) or a (di) alkylcyclopentadiene obtained by heating the monomer at 150W300°C, is partially hydrogenated by the ordinary method using Raney nickel, etc. as a catalyst, and thereafter carboxylated by Reppe reaction (reaction with water or an alcohol at 30W130°C under the pressure of CO in the presence of a catalyst, e.g. nickel, etc.), etc.
