为您科普:化工行业中无机化工行业的特点
来源:http://www.jnjrh.com 日期:2019-09-20 发布人:admin
关于化工的分类目前没有一个统一的规范,从大的方面能够分为有机化工和无机化工两大类,但是,两者又穿插一同不能截然分开。
At present, there is no unified standard for the classification of chemical industry, which can be divided into organic chemical industry and inorganic chemical industry in a large way. However, the two can not be separated completely.
无机化工
Inorganic chemical industry
1.酸类。包括盐酸、硫酸、硝酸和发烟硫磺酸。化工行业有“三酸两碱”之称,其中的“三酸”便指此三酸。
1. acids. It includes hydrochloric acid, sulfuric acid, nitric acid and fuming sulfuric acid. Chemical industry has the name of "tri-acid and two bases", in which "tri-acid" refers to the tri-acid.
(1)盐酸:主要用于制造氯化物的原料。
(1) Hydrochloric acid: It is mainly used as raw material for chloride production.
(2)硝酸:硝酸是用处很广的化工根本原料,是制造染料、化肥、炸药、医药、照相资料、颜料、塑料和合成纤维的重要原料。
(2) Nitric acid: Nitric acid is a basic chemical raw material widely used. It is an important raw material for making dyes, fertilizers, explosives, medicines, photographic materials, pigments, plastics and synthetic fibers.
(3)硫酸:硫酸也是重要的根本化工原料。
(3) Sulfuric acid: Sulfuric acid is also an important basic chemical raw material.
氨基磺酸
2.碱类。纯碱(碳酸钠)和烧碱(氢氧化钠),俗称“二碱”。(1)纯碱:纯碱是根本的化工原料之一,普遍用于化工、冶金、国防、建材、农业、纺织、制药和食品等工业,其耗量较大,属于大宗化工产品。
2. alkaloids. Soda (sodium carbonate) and caustic soda (sodium hydroxide), commonly known as "diabase". (1) Soda soda: Soda soda is one of the basic chemical raw materials. It is widely used in chemical industry, metallurgy, national defense, building materials, agriculture, textile, pharmaceutical and food industries. It consumes a large amount of chemical products.
(2)烧碱:氯碱工业已有近百年的历史,是根底化学工业,也是阅历过严重技术革新至今日臻成熟的大吨位的产品工业。烧碱在化学工业上用于消费硼砂、氰化钠、甲酸、草酸和苯酚等。
(2) Caustic soda: The chlor-alkali industry has a history of nearly 100 years. It is not only a basic chemical industry, but also a large-tonnage product industry which has experienced serious technological innovation and is now mature. In chemical industry, caustic soda is used to consume borax, sodium cyanide, formic acid, oxalic acid and phenol.
3.无机盐和化合物类。此类产品约有500余种,主要有钡化合物、硼化合物、溴化合物、碳酸盐、氯化合物及氯酸盐、铬盐、氰化物、氰化物、碘化合物、镁化合物、锰盐、硝酸盐、磷化合物及磷酸盐、硅化合物及硅酸盐、硫化合物及硫酸盐以及钼、钛、钒、钨、锆化合物等。
3. Inorganic salts and compounds. There are more than 500 kinds of such products, mainly barium compounds, boron compounds, bromides, carbonates, chlorides and chlorates, chromium salts, cyanides, cyanides, iodides, magnesium compounds, manganese salts, nitrates, phosphorus compounds and phosphate, silicates, sulphides and sulphates, as well as molybdenum, sulphate and molybdenum. Titanium, vanadium, tungsten, zirconium compounds, etc.
4.化肥类。主要是氨肥、磷肥和复合肥。
4. Fertilizers. Mainly ammonia, phosphorus and compound fertilizer.
5.气体产品。二氧化碳、氢气、氨气、氧气和各种惰性气体等。
5. Gas products. Carbon dioxide, hydrogen, ammonia, oxygen and various inert gases.
6.其他无机产品。主要有氧化物、过氧化物、氢氧化物、稀土元素化合物和单质等(约有100多种)。
6. Other inorganic products. There are mainly oxides, peroxides, hydroxides, rare earth compounds and substances (about 100 kinds).
