Where Can Sulfuric Acid be Used?

Sulfuric acid is one of the important items in the basic chemical market. The function of sulfuric acid in the nationwide economy is explained listed below.

1. For agricultural production services

For the manufacturing of plant food ammonium sulfate (frequently known as ammonium or plant food powder) as well as superphosphate (generally called superphosphate lime or calcium) these 2 sort of plant food production must take in a great deal of sulfuric acid.

2NH3 + H2SO4 ==== (NH4) 2SO4

Each manufacturing of lots of ammonium sulfate, it is needed to eat sulfuric acid (equal to 100% computation) 760kg, each production of tons of superphosphate, it is required to take in sulfuric acid 360kg.

For the manufacturing of pesticides Numerous pesticides need to be sulfuric acid as raw materials such as copper sulfate, zinc sulfate can be utilized as plant fungicide, thallium sulfate can be used as rodenticide, ferrous sulfate, copper sulfate can be utilized as herbicide. The most common insecticides, such as 1059 solutions (45%) as well as 1605 emulsions (45%), need sulfuric acid. The former manufacturing of 1t each, need to take in 20% fuming sulfuric acid 1.4 t the latter for each and every production 1t, require to consume sulfuric acid 36kg. For everyone acquainted with the DDT, each manufacturing 1t need 20% fuming sulfuric acid 1.2 t.

Sulfuric Acid

2. Services for industrial production

For the metallurgical industry and also metal handling in the metallurgical industry sector, specifically, the production procedure of non-ferrous metals require to use sulfuric acid. Electrolytic refining of copper, zinc, cadmium, nickel, the electrolyte will require to utilize sulfuric acid, some priceless metals refining, but likewise require to liquefy the sulphur to dissolve the other metals. In some metal machining process, such as nickel, chrome and also other steel parts, also require to utilize sulfuric acid to clean the surface area of the corrosion.

For the oil sector, gasoline, lubricants as well as various other petroleum products in the manufacturing process, require to focus concentrated sulfuric acid to get rid of one of the sulfur compounds and also unsaturated hydrocarbons. Petroleum refining per tonne requires regarding 24kg sulfuric acid, per lots of diesel refining requires regarding 30kg sulfuric acid. The preparation of activated clay used in the oil market also consumes a lot of sulfuric acids.

For various other chemical manufacturing as well as other industrial fields Several chemical productions needs the use of sulfuric acid. In concentrated nitric acid, focused sulfuric acid as drying out agent; Chlor-alkali industry, concentrated sulfuric acid to completely dry chlorine, hydrogen chloride gas; not natural salt market, such as cryolite (na3alf6), borax (na2b4o710h2o) Sodium, disodium hydrogen phosphate, lead sulfate, zinc sulfate, copper sulfate, ferrous sulfate and also various other sulfates are prepared with sulfuric acid. Numerous inorganic acids such as phosphoric acid, boric acid, chromic acid (h2cro4, in some cases, additionally refers to cro3), hydrofluoric acid, chlorosulfonic acid (clso3h); organic acids such as oxalic acid [( cooh) 2], acetic acid, As raw material. Furthermore coking chemical market (with sulfuric acid to the duty of ammonia in coke gas byproduct ammonium sulfate), electroplating industry, leather market, pigment industry, rubber sector, paper industry, paint sector (organic solvent preparation), industrial dynamite As well as lead storage battery manufacturing, and so on, are eating a substantial quantity of sulfuric acid.

3. to solve the people "wear" and also "make use of" and various other problems played by the role

For the production of chemical fiber for the people aware of the viscose cord, it needs using sulfuric acid, zinc sulfate, sodium sulfate blend as a viscose spinning coagulation bath. Each manufacturing of 1t viscose fiber, need to take in sulfuric acid 1.2 t ~ 1.5 t, the manufacturing of 1t-dimensional nylon short fiber, it is needed to eat 98% sulfuric acid 230kg, the production of 1t Carpenton monomer, require to utilize 1.6 t20% fuming sulfuric acid. Furthermore, in the nylon, acetate fiber.

Each production of 1t viscose fiber, require to consume sulfuric acid 1.2 t ~ 1.5 t, the production of 1t-dimensional nylon brief fiber, it is essential to consume 98% sulfuric acid 230kg, the production of 1t Carpenton monomer, require to make use of 1.6 t20% fuming sulfuric acid.
