| titleOfInvention | PROCESS FOR THE PREPARATION OF POLYETHERAL COCOOLS |
| abstract | The invention relates to a process for the preparation of polyether alcohols, which are suitable mainly for the production of rigid polyurethanes. The object of this invention is to develop a process for the preparation of polyether alcohols based on solid starter substances with high space-time yield and avoiding the use of functional solvents. According to the invention, this object is achieved by reacting polysaccharides such as starch and / or cellulose, which is present in fibrous form or as cellulose powder, and OH- or NH- and / or NH 2 -functional coinitiators, whose properties are the possible addition of catalysts influence, with a partial amount of alkylene oxide, a reaction mixture is prepared which, after removal of unreacted Koinitiatoren or after addition of further, possibly other OH or NH and / or NH2-functional Koinitiatoren and possibly catalysts reacted with the remaining amount of alkylene oxide is, wherein the amounts of the reaction components of the homogeneity of the resulting reaction mixture are dependent. |
