CATALYSEUR POUR LA HYDRATATION DIRECTE DE L'ETHYLENE A L'ALCOOL ETHYLIQUE ET PROCEDE D'OBTENTION

摘要

A novel catalyst for hydration of ethylene to ethyl alcohol comprises active synthetic silicon dioxide as a base having deposited thereon natural kieselguhr and phosphoric acid. The catalyst is prepared by precipitative silicon dioxide from sodium silicate with hydrochloric acid, filtering the precipitate, admixing it with natural kieselguhr and phosphoric acid and annealing the resultant composition.
