Abstract
Sulfuric acid compounds are removed from reaction mixtures by a reaction with unsaturated terpene compounds or with polybutadiene at elevated temperatures whereby products of reduction are formed which are volatilizable at the temperature of reaction and by expelling said products of reduction from the reaction mixture. Thus a product being substantially free from a sulfur content is obtained.
