METHOD OF PRODUCING POLYETHER ALCOHOLS Russian patent published in 2012 - IPC C08G65/26 C08G65/28 

Abstract RU 2448125 C2

FIELD: chemistry.

SUBSTANCE: method involves binding alkylene oxides to N-functional starting materials in a back-mixing reactor. The starting components are continuously fed into the reactor. One of said N-functional substances is solid at room temperature. Paste is prepared from the solid starting substance and also continuously fed into the back-mixing reactor. The mixture for producing polyether alcohols is in form of a paste and consists of at least one N-functional compound which is solid at room temperature and at least one N-functional compound which is liquid at room temperature.

EFFECT: simple and safe method of producing polyether alcohols, which enables to obtain products with narrow molecular weight distribution and where starting materials can be continuously fed.
