Embodiment 1

[0061] with a loop reactor of capacity 501 figure 1 In the plant shown, initially 40 kg of high boiling polyether alcohol were charged into the reactor. The polyether alcohols used are alkenyl-started polyethers of the form,

[0062] R 1 -(OC 2 h 3 Me) n -(OC 2 h 4 ) m -OH

[0063] in

[0064] R 1 is an alkenyl group having 3 carbon atoms,

[0065] n is 13 and m is 4.

[0066] Then measure 15 kg of 30% sodium methoxide methanol solution into the polyether alcohol in the reactor. In the closed condensation loop with valve 3 closed and valve 4 open, the reactants react at 110°C according to equilibrium reaction I, during which methanol is condensed down in condenser 5 until it reaches the condensation temperature of -15°C (initial stage). The partial pressure of methanol in the gas phase was determined from the condensation temperature and the residual methanol content in the liquid phase was determined by phase equilibrium, which corresponds to the poin...

Abstract

The present invention relates to a method for carrying out two consecutive chemical reactions simultaneously in a loop reactor with a liquid ejector and a closed condensation system. In particular, the present invention relates to a method for etherification of high boiling point polyether alcohols.

Description

technical field [0001] The present invention relates to a method for simultaneously carrying out two continuous chemical reactions in a loop reactor with a liquid jet ejector and a closed condensation system. In particular, the invention relates to a process for the etherification of high-boiling polyether alcohols. Background technique [0002] Some methods of producing chemicals involve two or more sequential chemical reactions, interdependent reactions, one of which is an equilibrium reaction, such as between high-boiling liquid reactants; The reactions are basically diffusion-controlled reactions in which a liquid intermediate product of a first reaction reacts with at least one gaseous reactant to form a final product. Currently, such methods of producing chemicals are produced on an industrial scale by combining the two reactions in a spatially , temporally and / or technologically separated. [0003] For example, in the industrial-scale Williamson (Williamson) method ...
