— 二甲胺基— 2,3— 二氯丙烷的制備 過程,指出了發(fā)生 副反應(yīng)的途徑和傳統(tǒng)的生產(chǎn)工藝中存在的問題,分析了原因和解決途徑,并提出了工藝改進(jìn)的具體辦法。小試成功地優(yōu)化了工藝條件,減少了副反應(yīng),并將其成果直接應(yīng)用于大生產(chǎn),大幅度地提高了 產(chǎn)品質(zhì)量和 收率。 Production process of 1-(dimethylamino)-2,3-dichloropropane was disussed. The way of side reaction and the existing problem in traditional process were put forward. And the reasons and solutions were analyzed. Process conditions were optimized, and side reaction was reduced in the lab scale experiment. The process that got in the test was applied in the production. Quality and yield were improved in a high range. |
