一、盐在化学工业中的重要作用众所周知,盐业是国民经济的基础产业。它不但是大家日常生活中必不可少的原料,更是化学工业之母。三酸两碱(盐酸、硫酸、硝酸;烧碱、纯碱)属于基本的化学工业,而其中的两碱是以盐为主要原料生产的,每生产1吨纯碱或烧碱平均消耗1.55吨原盐。全世界用于生产两碱、氯和氯的衍生物等80多种基本化工产品所用的盐,占全世界总盐耗量的60%以上。而在工业发达国家,化工用盐一般都占到总盐耗量的90%以上。另外,工业盐在
First, the important role of salt in the chemical industry As we all know, the salt industry is the basic industry of the national economy. It is not only an indispensable raw material in our daily life, but also the mother of the chemical industry. Triacid bases (hydrochloric acid, sulfuric acid, nitric acid; caustic soda, soda ash) belong to the basic chemical industry, and two of them are produced by using salt as the main raw material. Each producing one ton of soda ash or caustic soda consumes an average of 1.55 tons of crude salt. The salt used in more than 80 basic chemical products, such as derivatives of two bases, chlorine and chlorine, accounts for over 60% of the total salt consumption in the world. In industrialized countries, chemical salt generally accounts for more than 90% of total salt consumption. In addition, industrial salt in
