FREMGANGSMAATE OG KATALYSATOR FOR ALKOXYLERING AV ALKANOLER

摘要

Barium and strontium together with promoters are used as catalysts for the alkoxylation of alcohols of all classes. The reaction is carried out at temperatures of from about 90 DEG C to about 260 DEG C to yield an alkoxylation product. The products obtained have very narrow adduct distribution with low levels of by-products and unreacted free alcohols. The catalysts disclosed are preformed. These preformed catalysts reduce reaction time while providing narrow mole adduct distributions.
