Abstract

1480432 Polyethers HOECHST AG 13 Jan 1975 [16 Jan 1974] 1339/75 Heading C2C [Also in Division C5] Novel polyethers having the formula wherein R is (C 1 -C 4 )alkyl, x and z are 1, 2 or 3, are prepared by the reaction of an ether of the formula ROÀ(CH 2 CHO) x H or a mixture thereof, with ethylene oxide and propylene oxide at an elevated temperature and pressure in the presence of an alkaline catalyst, by either (a) reacting an excess of the ether in a first reaction step with propylene oxide and, after removal of the excess starting ether, reacting the product obtained in a second reaction step with ethylene oxide, or (b) reacting ethylene oxide, propylene oxide and an excess of the ether, relative to the oxide mixture, and distilling the mixture under reduced pressure to obtain a sump product consisting of the final product. The novel compounds can be used as brake fluids.
