Abstract
1470864 Ethylene oxide and/or propylene oxide adducts BASF AG 26 Nov 1974 [27 Nov 1973] 51115/74 Heading C2C [Also in Division C3] The invention comprises a process for the continuous reaction of a compound bearing at least one active hydrogen atom with from 1 to 12 times its molar amount of ethylene oxide and/or propylene oxide in a heat-exchanger-surrounded coil reactor tube having a high 1/d ratio, at a temperature which is maintained constant by means of a heating jacket and a pressure at which the reaction mixture is liquid and in the presence of an alkali-reacting material acting as catalyst, wherein (a) the reaction is carried out at a temperature level maintained substantially constant over the length of the coil reactor tube at from 190‹ to 240‹ C., any temperature peaks being present in the first half of the reaction path only and measuring not more t han 30‹C. above the inlet temperature of the mixture, the absolute upper limit of any such temperature peaks being 240‹ C., (b) the l/d ratio of the coil reactor tube is 10<SP>5</SP> : (1 to 10) and the absolute length of the tube is from 100 to 160 metres, and (c) the throughput of the reaction mixture is from 20 to 60 kg/hr. The starting material is suitably a (C 6 -C 22 ) mono- or poly-hydric alcohol or a (C 4 -C 18 ) alkyl phenol.
