Abstract: Crude oil deemulsifiers based on alkoxylated polyethyleneimines are obtained by reacting polyethyleneimine having a molecular weight from 2500 to 35,000 with in each case 5 to 40 mol of propylene oxide and ethylene oxide per ethyleneimine unit in the polyethyleneimine and are used for deemulsifying crude oil emulsions at 10 DEG C to 130 DEG C.

Abstract: The present invention relates to a process for reacting epoxides with an initiator compound in the presence of a double metal cyanide compound as a catalyst, said process having a shortened induction period, and the double metal cyanide compound being activated by adding the epoxide to a mixture of double metal cyanide compound and initiator compound at an internal reactor pressure of less than 1 bar, and also to the polyethers themselves obtainable by such a process.
