化學(xué)性質(zhì):無(wú)色結(jié)晶。有順式和反式兩種。溶于乙醇,順式熔點(diǎn)110.5℃,反式熔點(diǎn)249-250℃。
用途:有機(jī)合成中間體,用于合成對(duì)氯苯丙酸,生產(chǎn)除草劑麥敵散。
用途:用于合成除草劑
生產(chǎn)方法:由對(duì)氯苯甲醛與乙酐反應(yīng)而得。將對(duì)氯苯甲醛、乙酐和乙酸鈉在一起在180℃下反應(yīng)13h。反應(yīng)畢,稍冷,倒入水中,過濾,用水洗滌濾餅,用氨水反復(fù)溶解,至僅殘留少量棕黃色粘稠狀物為止。將所得銨鹽溶液過濾,用3N稀硫酸將對(duì)氯肉桂酸重新析出,經(jīng)過濾干燥得產(chǎn)品。產(chǎn)率約為80%。
