説明
In order to explain the correlations of somei nteresting experimental results from the preceeding reports 2, 3, and 4 and some supplements were made and the phosgenation reaction mechanism has been investigated on these viewpoints. i. NaO-B1-ONa gives HO-B1-O·COCl, Cl·CO·O-B1-O·COCl and HO-Bn-O-COCl type origomers by the surface reaction with phosgene under dissolution in-to methylene chloride layer. ii. elevation the temperature from 0°c to 25°c during blow-in of phosgene a direct formation of origomer from NaO-B1-O·COCl and decreases a formation of origomer through Cl·CO·O-B1-O·COCl. iii. Increase of the amount of sodium hydroxide during blow-in of phosgene cause an increase of formation of Cl-CO-O·B1-O·COCl and the ratio of (-O·COCl/OH) terminal groups of origomer due to the increase of the ratio of NaO-B1-O-COCl to HO-B1-O·COCl
