Concentrated sulfuric acid can also be made into other forms. For example, the high concentration of SO3 can be made through the sulfuric acid oleum (H2S2O7). Related to the concentration of fuming sulfuric acid, it is usually a percentage of SO3 in H2SO4 authentic or a percentage of authentic, both. Concentration is generally called 'oleum' was 45% (including 109% H2SO4) or 65% (including 114.6% H2SO4). 100% pure solid oleum sulfuric acid plant in Huizhou, a melting point of 36 ℃. Polarity and the conductive pure sulfuric acid is a very large polar liquid, the dielectric constant thereof is about 100. Because between its molecules and other molecules can mutually protonated, causing it to high conductivity, this process is known as proton from migration. Process that occurs is: 2H2SO4 ==== H3SO4 + HSO4 because we are professionals so we do a better credit-quality first quality assurance solutions at reasonable prices for the chemical fiber production and people's basic needs for the people familiar rayon sulfuric acid manufacturers, it 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. Further, nylon, cellulose acetate, polyacrylonitrile fibers and other chemical fiber production, but also a considerable amount of sulfuric acid used. 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 resin, sulfuric acid required 2.68t, known as the 'king of plastic "teflon, each producing 1t Fuzhou sulfuric acid plant, sulfuric acid required 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 necessary raw materials nitrocellulose sulfuric acid plant, sulfuric acid, are required. 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. In addition, the preparation of a number of preparation of 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.
