-
Paragraph 0019-0027, (2020/03/25)
The raw material is simple and cheap, [2.1.1] operation is simple, the reaction process is, easy to monitor, S1, the process is stable, the product quality is good, cost, and the like, is prepared.S2, The raw material is prepared by dropwise adding an ether solvent tetrahydrofuran, diisopropylamine, dropwise to a room temperature reaction, to obtain a crude 20min;S3, oil pump by dropwise adding a stabilizer hexamethylphosphoric acid methyl triamine, dropwise to prepare a crude oil pump under reduced pressure dropwise, dropwise adding a stabilizer hexamethylphosphoric acid methyl ester, dropwise to obtain a crude product of diethyl [2.1.1] hexane - 1111,3-dimethyl, dicarboxylate, The raw material is obtained by dropwise adding an acetic acid quenching reaction, dropwise adding. a stabilizer hexa-methylphosphoric acid methyl ester.
