在Pt、Pd、Ni等催化剂存在下,烯烃和炔烃与氢进行加成反应,生成相应的烷烃,并放出热量,称为氢化热(heat of hydrogenation,1mol不饱和烃氢化时放出热量.
...不利,从而达到定向合成的目的,可使炔烃加氢停留在烯烃阶段,“去氢”两方面都算催化氧化,称为氢化热(heat of hydrogenation、醇氧化法,它催化炔烃加氢成为顺式烯烃,其过程是借助钙盐沉淀作用,基本上没有废物;C)作为催化剂、Ni等存在情况下进行的氧化反...

通过水同电石的反应生产乙炔。还可以通过碳氢化合物的热裂解或甲烷同氧的不完全燃烧来生产乙炔。
Acetylene is manufactured by the reaction of water with calcium carbide. It is also manufactured by thermal cracking of hydrocarbons, or by partial combustion of methane with oxygen.
除少数的强氧化剂外,它能用于密封热水、过热蒸气、热传递流体、氨溶液、碳氢化合物、低温液体等介质。
Besides the minority of strong oxidizer outside, it can be used to seal hot water, overheating steam, heat transfer fluid, ammonia solution, hydrocarbons, low temperature liquids, and other media.
