摘 要:本文介绍了苄基胂酸合成原理,通过合成条件试验,找出合成苄其(?)酸最好的条件是:苄氯与亚砷酸钠的克分子比为0.9∶1,反应温度80℃,反应时间为4.5小时。在小型试验的基础上进行了工业试验,工业试验结果表明,用这种方法生产苄基胂酸是可行的。
Abstract: The synthesis theory of benzyl arsinic acid is dealt with in this paper.The best conditons of synthesis benzyl arsinic acid found out through con-ditional experiments are.grammolecule ratio of benzyl chloride to sodiumortho-arsenite 0.9:1;reation temperature 80℃;reaction time 4.5 hrs.On thebasis of conditional experiments,the industrial experinent has been carriedout,the results of which shows:the above mentioned synthesis method ispractical for the production of benzyl arsinic acid.
