摘要
对乙草胺生产中的缩合岗位进行了工艺改进探索 ,实现了用市售的 4 2 %液碱替代 4 7%的液碱直接用于生产 ,提高了原料的转化率和产品收率 ,降低了生产成本 .
The improvement of the condensation technology on the ethylchlor production is carried out. It has been realized that the sodium hydroxide solution of 47 percent is replaced with the solution of 42 percent, thus raising the conversion rate and the yield of product and reducing the production cost.
