Inorganic Chemicals typical chemical plant is the first in the 1740s to build a sulfuric acid plant in the UK. First with sulfur as raw material, with pyrite as raw materials, products are mainly used for making nitric acid, hydrochloric acid and drugs, then the output is not large. In the original industrial revolution hydrazine hydrate, the textile industry has developed rapidly. It glass, soap and other industries have a lot of alkali, and the Academy of Sciences under the alkaloids and trona reward obtain patents to salt as raw materials plant, system too, and led to sulfuric acid (one of the raw materials) industrial development; for the manufacture of hydrogen chloride hydrochloride hydrazine hydrate quotes, chlorine, bleaching powder as the industry urgently needed materials into the production of caustic soda can be produced, the raw materials and byproducts are fully utilized, this was the chemical industry initiative; filling device for absorbing hydrogen chloride, rotary kiln calcination of raw materials and semi-finished products, as well as concentrated aqueous hydrazine hydrate, crystallization, filtration equipment used, and gradually applied to other chemicals business, for the chemical unit operations and lay a foundation 吕布兰 law in the early 1900s gradually Solvay process (see) to replace .19 century the emergence of electrolysis of salt so that the basis for the entire chemical industry. - acid, alkali production has begun to take shape. petrochemical production in 1920 with the United States, this is the beginning of large-scale development of petrochemical .1939 Standard Oil Company in the United States has developed a hydrogen catalytic reforming process Pro, which became an important source of aromatics .1941 United States into the first a raw material that ethylene device. After World War II, the market continues to expand due to chemical products, oil can provide a lot of cheap organic chemical raw materials, and because of the development of chemical production technology, and gradually form a petrochemicals and even does not produce oil regions, such as Western Europe, Japan, also with crude oil as raw material, the development of petrochemicals. same material or the same product, all chemical companies have different process routes or different catalyst. Because the basic organic raw material monomer and polymer are in petrochemical raw materials, so people ethylene production as a measure of organic chemical symbol of .80, more than 90% of the organic chemical products, from petrochemicals. For example, such as, calcium carbide acetylene as raw materials in the past, then switch oxychloride method was to produce ethylene chloride, ammonia with propylene oxide (see) method to produce acrylonitrile .1951 years, natural gas as raw material, give carbon monoxide and hydrogen by steam reforming, so get attention.
