Basic necessities for the people to solve production of chemical fibers for the people familiar viscose rayon, which requires the use of sulfuric acid, a mixture of zinc sulfate, sodium sulfate as viscose spinning coagulation bath. Production of viscose fibers per 1t need to consume sulfate 1.2 ~ 1.5t, each producing 1t vinylon short fiber, will consume 98% sulfuric acid 230kg, 1t kapron each monomer production, need 1.6t20% fuming sulfuric acid. In addition, nylon, cellulose acetate, polyacrylonitrile fiber and other chemical fiber production of sulfuric acid, also uses a considerable amount of sulfuric acid. Chemical fibers for the production of plastics and other polymer compound other than the polymer compound, in a growing national economy plays an important role. For every 1t epoxy required 2.68t sulfuric acid corrosion, known as "plastics king" of polytetrafluoroethylene, each producing 1t, need to use sulfuric acid 1.32t; silicone rubber, silicone, styrene-butadiene rubber and nitrile rubber such as the production, but also we have to use sulfuric acid. Dye industry for almost a dye (or intermediate) prepared without the use of sulfuric acid. Preparation of azo dyes requires sulfonation reaction intermediates, aniline dye intermediates required for nitrification, both need to use a lot of concentrated sulfuric acid or fuming sulfuric acid. So it has a sulfuric acid plant some dye works to meet the needs. For the production of daily necessities production of synthetic detergent needs with fuming sulfuric acid and concentrated sulfuric acid. Plastic plasticizers (such as phthalic anhydride and phthalic acid esters), celluloid products raw materials needed to nitrocellulose, need sulfuric acid. Glassine paper, parchment manufacture, also need to use sulfuric acid. In addition, textile printing and dyeing industry, ceramic industry, hardware industry, soap industry, artificial flavor industry and other productive sectors, but also require the use of sulfuric acid. Preparation of sulfa drugs for the pharmaceutical industry in the sulfonation reaction, during the preparation of the powerful bactericide Furacilin nitrification are required sulfuric acid. Further preparation production of sulfuric acid, prepared many antibiotics commonly used drugs such as aspirin, caffeine, vitamin B2, vitamin B12 and vitamin C, some hormones, isoniazid, merbromin, saccharin, etc., all need to use sulfuric acid . Corrosion and chemical properties of pure sulfuric acid heated to 290 ℃ decompose to release some sulfur trioxide, until the concentration of the acid fell 98.3%, whereupon the constant boiling solution of sulfuric acid boiling point of 338 ° C. Anhydrous sulfuric acid is reflected in the ability to give a proton and pure sulfuric acid still has a strong acid 98% sulfuric acid and substantially no difference in pure sulfuric acid, sulfur trioxide dissolved in fuming sulfuric acid is a super acid system, acidic than pure sulfuric acid, but there is a widespread misunderstanding that the dilute sulfuric acid is stronger than concentrated sulfuric acid, this idea is wrong. Indeed, the first step ionization fully diluted sulfuric acid, a large amount of hydronium ion H3O; however concentrated sulfuric acid and water, their own self-dual ionization will produce some sulfuric acid hydronium H3SO4, precisely fit this part sulfuric acid protons, resulting in pure sulfuric acid It has a very strong acid, although small, but much stronger acidic proton hydration than it, so the Hammett acidity function up to -12.0 pure sulfuric acid. In sulfuric acid solvent system, H3SO4 often act acid protonated Many substances can produce ionic compounds: NaCl + H2SO4 == NaHSO4 + HCl (without heating can be quickly reacted) KNO3 + H2SO4 → K + HSO4 + HNO3HNO3 + H2SO4 → NO2 + H3O + 2HSO4CH3COOH + H2SO4 → CH3C (OH) 2 + HSO4HSO3F + H2SO4 → H3SO4 + SO3F (Nafion more acidic) above reaction with HNO3 generated by NO2, contribute to the nitration reaction aromatics.
