Title
(EN) PROCESS FOR PRODUCING METAL-FREE GUERBET ALCOHOLS
Abstract
(EN) THERE IS PROVIDED A PROCESS FOR PRODUCING GUERBET ALCOHOLS NOT CONTAINING ANY HEAVY METALS OR SOAPS, WHEREIN PRIMARY AND/OR SECONDARY ALCOHOLS HAVING 2 TO 30 CARBON ATOMS ARE CONDENSED AT ELEVATED TEMPERATURE IN THE PRESENCE OF ALKALINE CATALYSTS AND/OR HEAVY METAL CATALYSTS WHILE ELIMINATING THE REACTION WATER, AND THE REACTION PRODUCT IS IMMEDIATELY SEPARATED BY DISTILLATION WITHOUT ANY ADDITIONAL PURIFICATION.
