摘要
以对甲基苯甲腈为原料 ,经氯化、环化、缩合三步反应合成了荧光增白剂双苯并口恶唑二苯乙烯 (OB 1) .通过对化合物的元素分析、红外光谱以及在DMF中紫外吸收光谱的测定 ,确定了目标分子 .经HPLC测定 ,产品纯度大于
With p methylbenzonitrile as raw material, the fluorescent bleaching agent bisbenzoxazole diphenylethene(OB 1)was synthesized by chlorination, cyclization and condensation. The objective molecule was determined through testing the compound with elementary analysis.IR spectrum and ultra violet absorption spectrometry in DMF.HPLC analysis proved that the purity of the product was more than 99 0 0
