按药典規定,本品的制造系以硝酸、硫酸、銅屑和酒精为原料,將原料按量混和置蒸溜瓶中于70～80℃蒸出亞硝酸乙酯,再以酒精吸收之。此法优点在于制造过程比較簡單,容易掌握。但制造时需用硝酸和銅屑为原料,而硝酸和金屬銅均为重要工業原料,目前供应比較紧張,因此有另寻其它制法的必要。作者考虑到土硝是一种比較容易获得的原料,因此根据N.F.上的規定,試用土硝、硫酸和酒精为原料以制造本品,其基本原理可以下列化学方程式表明:
According to Pharmacopoeia regulations, the manufacture of this product to nitric acid, sulfuric acid, copper scrap and alcohol as raw materials, the amount of raw materials by mixing the amount of distilled water bottles steamed at 70 ~ 80 ℃ ethyl nitrite, and then alcohol absorption. The advantage of this method is that the manufacturing process is relatively simple and easy to grasp. However, it is necessary to use nitric acid and copper scrap as raw materials for manufacturing, while nitric acid and metallic copper are both important industrial raw materials. Currently, the supply is relatively tight, so there is another need for finding other manufacturing methods. The authors consider soil nitrate is a relatively easy access to raw materials, so according to the provisions of N.F., try soil nitrate, sulfuric acid and alcohol as raw materials to make this product, the basic principle of the following chemical formula shows:
