| titleOfInvention | Method for producing polycarbonate diol |
| abstract | (57) [Summary] [PROBLEMS] The present invention provides hydrolysis resistance, oil resistance, heat resistance, An object of the present invention is to provide a method for efficiently producing a polycarbonate diol having 36 carbon atoms, which is excellent in weather resistance and the like, and can be suitably used as a soft segment of a polyurethane or a thermoplastic elastomer, or a polymer plasticizer, with a high yield. SOLUTION: The present invention is to distill a by-product alcohol or phenol from a dimer diol having 36 carbon atoms and a carbonate compound at 110 to 280 ° C under normal pressure and then under reduced pressure in the presence of a transesterification catalyst. The present invention relates to a method for producing a polycarbonate diol having a hydroxyl group at both ends of a main chain and a long alkyl side chain, which comprises subjecting a transesterification reaction while leaving. |
