氰化钠(NaCN)又名山奈,是一种重要的无机化工原料,可用于电镀、黄金、白银等贵金属的提炼,也可用于医药、农药生产以及无机化工产品的生产。我国氰化钠生产方法有轻油裂解法、氨钠法、安氏法和丙烯腈副产品法。目前我国总生产能力为8—9万吨/年.近年来,随着我国黄金业、化工医药的迅速发展,对氰化钠需求也日益增长,引发了1995年度氰化钠价格的大幅上扬。而在1996年中,由于 Sodium cyanide (NaCN), also known as Shannai, is an important inorganic chemical raw material that can be used for electroplating, gold, silver and other precious metal extraction, but also for the production of pharmaceuticals, pesticides and inorganic chemical products. Sodium cyanide production methods in our country have light oil cracking method, ammonia, France’s law and acrylonitrile byproduct method. At present, China’s total production capacity of 8-9 million tons / year.In recent years, with the rapid development of China’s gold industry, chemical industry and medicine, the demand for sodium cyanide is also growing, triggering a sharp rise in sodium cyanide prices in 1995. And in mid-1996, due
