我厂酊制車间为將酊剂药渣中回收的醇加以利用,曾进行了一些試驗工作,在長期生产的体会,我們認为有的收回醇可以直接用到生产上去,如远志酊,但有的是很不适当的,如橙皮、复方龙胆酊等的殘药中含有大量揮發性成份。或数种药渣混合蒸餾时揮發性成份和醇同时被蒸餾出来,餾出液再进行稀釋时往往产生大量白色乳状液,此証明該醇巳不純淨,用到生产中可能对酊剂的澄明度和沉淀产生很不好的影响。我們经过种种方法試驗,都不能解决加水稀釋时不产生白色混濁問题,最后我們用加入滑石粉进行处理試驗,于收回醇中加水稀释,使含量至40%以下成混濁液,加入 Our factory smashing the workshop used the alcohol recovered from the slag of the scorpion slag, and conducted some experiments. In the long-term production experience, we believe that some of the alcohol recovered can be used directly in production, such as Polygala, but Some are very inappropriate, such as orange peel, compound gentian and other residual drugs contain a lot of volatile components. When several kinds of dregs are mixed and distilled, the volatile components and the alcohol are simultaneously distilled out. When the distillate is diluted again, a large amount of white emulsion is often produced, which proves that the alcohol is not pure, and the clarity of the liniment may be used in the production. And sedimentation has a very bad effect. We have not tried to solve the problem of white turbidity when diluted with water through various methods. At the end we used talcum powder for the treatment test. We diluted it with water after recovering the alcohol to make the content less than 40% into a turbid liquid.
