摘要
采用无溶剂二步法制得了双酚A型苯并口恶嗪,用红外光谱和核磁氢谱对它进行了表征,并将它的初级产品和溶剂法制得的苯并口恶嗪的初级产品的成环率进行了比较。并通过比较发现,无溶剂二步法制得的苯并口恶嗪的成环率高。
Bisphenol A- Based Benzoxazine was prepard through two-step in solvenless systems and its raw product was compared to the solven＇s raw product,the yields of two raw products were characterized by FTIR and HNMR and we could find the yields of ring in the raw products of two- step in solvenless systems was higher than the yields in the solven＇s.
