There are several methods of instrial proction of fumaric acid. The main source of benzene in the presence of a catalyst (or butene) oxidation to form maleic acid (or maleic anhydride), and then derived by isomerization. The benzene (or 80% of the butene) and the excess air in a fluidized bed or fixed-bed reactor for oxidation reaction of maleic anhydride was absorbed into the cycle of acid maleic acid. And then by bleaching filter, maleic acid in Thiourea catalyst under isomerization, the reaction by filtration, washing, drying derived fumaric acid. Isomerization catalyst had been adopted in ammonium sulfate - ammonium bromide mixtures, or metal salts, amine salts, thiols, and 10-20% hydrochloric acid. Carbohydrates such as sucrose, glucose, maltose fermentation by Hagan may also be obtained fumaric acid. With carbohydrate fermentation method, 1t procts need to consume food 8t, economy is very uneconomical, the domestic research to liquid paraffin instead of food fermentation, in order to C16-C18 wax content of more liquid as the carbon source, after 80-88h fermentation, liquid wax conversion rate of about 50% extraction rate of 50%. Furfural laws to furfural as raw material, derived by oxidation of sodium chlorate.
[Edit this paragraph] Uses
Fumaric acid for the proction of unsaturated polyester resins, such resins are characterized by good resistance to chemical corrosion, heat resistance Ye Hao; fumaric acid and vinyl acetate copolymer is a good adhesive, and styrene copolymer is to create glass fiber reinforced plastic materials, fumaric acid obtained by the non-toxic plasticizer that can be used in contact with food vinyl acetate latex. The proct is a medical and optical bleaching agent fine chemicals intermediates in the pharmaceutical instry for the antidote dimercaptosuccinic acid proction, will be in fumaric acid with sodium carbonate and, that is, to be anti-butene sodium ( [17013-01-3]), and then replaced with ferrous sulfate to be fumaric acid iron, is used for the treatment of small drug-rich red blood cell anemia blood iron. The proct as a food additive - sour agent, used in soft drinks, fruit candy, jelly, ice cream and so on, mostly sour agent citric acid and use, fumaric acid and sodium hydroxide reaction made of a single salt, also used as a sour condiment, but also used as a synthetic resin, mordant intermediates.

❺ 丁烯－1的分子式

就是普通的丁烯，其双键在1号位
CH2＝CH-CH2-CH3
无色可燃气体。熔点-185.35℃。沸点-6.25℃。相对密度0.5951。闪点-80℃。不溶于水，易溶于乙醇、乙醚。与空气形成爆炸性混合气体，爆炸极限1.6％～10％(体积)。具有典型烯烃的化学性质，可发生加成、烷基化、加氢、氢甲酰化等反应。由石油烃裂解、炼厂催化裂化所得的碳四馏分用萃取分离法分出丁二烯，再用化学法分出异丁烯后的馏分，经蒸馏精制得1-丁烯。亦可采用正丁醇脱水或正丁烷脱氢制得。是重要的基础化工原料之一。主要用于脱氢制丁二烯，水合制仲丁醇，亦用作聚合的第二单体。
