摘要
用不同规格的乙醛酸与邻苯二胺反应合成２－羟基喹口恶啉，在优化反应条件下，对不同规格的乙醛酸，产品收率为８８．７％～９５．０％。与传统方法相比，产品质量、收率和生产成本明显改善。
Hydroxyquinoxaline was prepared by reacting o phenylenediamine with glyoxylic acid of different grades. At optimized conditions, theyieldwas88.7%～95.0%with glyoxylic acid of different grades. Compared with the old method,the quality and yield of the product were improved,and the cost was reduced.
