麻醉醚在贮藏过程中易受各种因素的影响而变质,变质的麻醉醚是不能再供麻醉用的。如何使已变质的废品重新变为药用品,以节约药材,是我们需要研究解决的问题。近几年来我们趁冬春两季气温较低时进行了一些试验和成批的精制工作,获得了较好的结果。现将方法与几点体会简介如下。处理方法一、高锰酸钾法本法是利用硫酸亚鉄的还原性,在硷性溶液内,首先将过氧化物除去。经过除去过氧化物的醚,利用高锰酸钾氧化作用除去醛类,然后经过数次洗涤除去反应后的水溶性杂质。
Anesthetic ether in the storage process susceptible to various factors, deterioration, deterioration of the anesthetic ether can no longer be used for anesthesia. How to make the spoiled waste into medicinal products to save the medicinal herbs is the problem we need to study and solve. In recent years, we took some trials and batch refining work when the temperature was low in winter and spring, and achieved good results. Now the method and experience a few are as follows. A method of treatment, potassium permanganate method This method is the use of sulfate 鉄 reducibility, in alkaline solution, the first peroxide will be removed. After removal of the peroxide ether, the use of potassium permanganate oxidation to remove aldehydes, and then after several washing to remove the water-soluble impurities after the reaction.
