摘要
针对草净津在工业化生产中存在的收率不稳定、产品质量差等问题进行了分析研究,发现循环溶剂、主要原材料以及中间体的质量对草净津的收率和产品质量都有不同程度的影响,而影响的主要因素是中间体丙酮氰胺的质量.通过对回收溶剂的处理、原材料的提纯和对中间体的精制,使草净津合成的工艺条件得到进一步优化,从而使草净津以三聚氯氰计的产品总收率达90%-95%,产品含量可达970 g·kg^-1,且收率和质量都相当稳定.
This paper analyzes the instability of cyanazine about its yield and quality in industrialisation production.The results show that the quality of recycle solvent,main material and intermediate influence the yield and quality of cyanazine,however,the quality of the middle intermediate and acetone cyanamide,significantly impacted the cyanazine synthesis.The purity and yield of cyanazine is better than before by treating with recycle solvent,purifying the main material and acetone cyanamide.Cyanazine yield was 90%~95%,while the product purity was about 970 g·kg^-1 and both the quality and the yield were consistent across batches.
