摘要
以对二甲苯为原料,通过氯化反应,用乌洛托品法水解氯化物合成对苯二甲醛,收率78.4%,含量99.5%。以二甲苯为溶剂,邻腈基苄基氯和亚磷酸三乙酯为原料,通过Abuzov反应合成邻氰基苄基膦酸二乙酯,收率86.5%。邻氰基苄基膦酸二乙酯通过Wittig反应和对苯二甲醛缩合制得1,4-双(2-氰基苯乙烯基)苯,收率84.1%,含量99.5%(HPLC)。
1 ,4-Dimethylbenzene was chlorinated by dry Cl2 ,then the mixed chloride products was hydrolyzed to terephthalaldehyde by hexamethylenetetramine. The purity of the product was 99.5% and the yield is 78.4%. Diethyl o-eyanobenzyl phosphonate was synthesized by the esterification reaetion of trieth- yl phosphatidate and o-cyanobenzyl chloride dissolved in dimethylbenzene,the yield is 86.5%. 1,4-bis （o-eyanostyryl）-benzene was synthesized from diethyl o-eyanobenzyl phosphonate and terephthalaldehyde. The purity of the produet is 99.5% （HPLC） and the yield is 84.1%.
