摘要
对四聚乙醛 (熔点 2 46 .2℃ )生产中副产物三聚乙醛 (熔点 12 .5℃ )的解聚工艺进行了研究改进。将常压间歇法改为加压连续法 ,既节能降耗 ,又减少污染 。
The depolymerization technique of by product paraldehyde(MP. 12.5?℃)in metaldehyde(MP.246.2?℃)production was studied for improvement. The technique of pressurization and continuity had taken the place of the one of atmosphere and intermittence. It was achieved to economize energy resources, cut down the consumption of raw materials,and reduce pollution. [WT5HZ]
