查询词典 antimonic chloride

With trimethyl,4-dodecylbenezyl ammonium chloride and 18-crown-6 as pase-transfer catalysts, the azidation of polyepichlorohydrin in poly and H2O were studied. The reaction discipline and mechanism were discussed. The results show that the system with trimethyl, 4-dodecylbenezyl ammonium chloride as phase transfer catalyst and PEG as medium is a safe and effective approach to glycidyl azide polymer preparation, and azidational ratio of PECH can reach 97% above within 15 h.
