| titleOfInvention | Method for producing polyol and the polyol |
| abstract | In the presence of a catalyst, castor oil or castor oil condensate is used as the initiator, and ethylene oxide is uniformly ring-opened and added to the initiator without causing low molecular weight by-products due to decomposition of the initiator, and the hydroxyl group is primaryized with high efficiency. A method for producing a polyol having a high degree of biomass and a polyol produced by the production method are provided. A process for producing a polyol in which a heterocyclic compound is subjected to ring-opening addition to at least one initiator selected from castor oil and castor oil condensate in the presence of a cationic polymerization catalyst, wherein the heterocyclic compound comprises a cyclic ether and a cyclic ester A compound selected from the group, at least a part of which is ethylene oxide, and the cationic polymerization catalyst has at least a fluorine-containing aryl group or a fluorine-containing aryloxy group, and is selected from the group consisting of an aluminum compound and a boron compound A method for producing a polyol, which is one kind. |
