摘要 以水杨醛为原料一步法生产邻羟基苯甲腈。61.5g(0.5mol)水杨醛、42g(0.6mol)盐酸羟胺和500mLN-甲基吡咯烷酮,110～115℃下反应5h,得产品邻羟基苯甲腈,摩尔收率91.2%,产品含量99%。 2-Hydroxybenzonitrile was preprared in high yield in a one-pot process by reacting salicyladehyde with hydroxylamine hydrochloride in N-methylpyrrolidone at 110 to 115℃ for 5 h. After purification ,the yield of the product is 91.2% and content 99%.
