Abstract
A találmány tárgya pofiéter-alkoholok előállítására szolgáló eljárás,H-funkcionális vegyületeknek alkilén-oxidokkal való katalitikusreagáltatásával, ahol katalizátorként legalább egy multifém-cianidvegyületet alkalmazunk, azzal, hogy a bázikus és savas szennyeződésektartalma, amelyek lecsökkentik a katalizátor aktivitását, a kiindulóvegyületben és/vagy alkilén-oxidokban összességében 100 ppm-nélkisebb. ÓThe subject of the invention is a process for the production of polyether alcohols by the catalytic reaction of H-functional compounds with alkylene oxides, where at least one multi-metal cyanide compound is used as a catalyst, with the content of basic and acidic impurities, which reduce the activity of the catalyst, in the starting compound and/or alkylene -oxides is less than 100 ppm overall.
