丁烯英語怎麼說及英文翻譯

❶ 求四個英文化學物的中文名稱 不要翻譯軟體直譯~~

樓上的把逗號後的內容歸到下一行了，其實這是倒裝寫法，在Scifinder搜索結果中會遇見。

Butanoic acid, 3-methyl- = 3-Methyl-butanoic acid： 3-甲基丁酸
2-Butenoic acid, 3-methyl- = 3-Methyl-2-butenoic acid：3-甲基-2-丁烯酸
9-Octadecenoic acid, (E)- = (E)-9-Octadecenoic acid：反-9-十八碳烯酸，俗名反油酸

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.

❸ 幫忙翻譯一個英語句子，謝謝。

在甲苯和具有相同的初始摩爾分數的正癸烷的存在下，在650 K時，形成一氧化碳減少到原來的50%，乙醛減少到原來的12%，1-丁烯減少到原來的1.5分之1，乙烯和丙烯減少到原來的二分之一。
後面幾句省略了rece，rece by a factor of幾就是變為原來的幾分之1.

❺ 丁烯－1的分子式

就是普通的丁烯，其雙鍵在1號位
CH2＝CH-CH2-CH3
無色可燃氣體。熔點-185.35℃。沸點-6.25℃。相對密度0.5951。閃點-80℃。不溶於水，易溶於乙醇、乙醚。與空氣形成爆炸性混合氣體，爆炸極限1.6％～10％(體積)。具有典型烯烴的化學性質，可發生加成、烷基化、加氫、氫甲醯化等反應。由石油烴裂解、煉廠催化裂化所得的碳四餾分用萃取分離法分出丁二烯，再用化學法分出異丁烯後的餾分，經蒸餾精製得1-丁烯。亦可採用正丁醇脫水或正丁烷脫氫製得。是重要的基礎化工原料之一。主要用於脫氫制丁二烯，水合制仲丁醇，亦用作聚合的第二單體。
