n.乙炔

In the ethyne molecule, a double bond links together the two carbon atoms. 在乙烯分子中是由一個(gè)雙鍵將兩個(gè)碳原子連結(jié)在一起的。

The research of acrylic acid and 1,4-butanediol series products synthesized by ethyne is the emphasis of this paper. 文中著重闡述了國內(nèi)天然氣制乙炔與電石法乙炔生產(chǎn)成本比較，重點(diǎn)還介紹了乙炔羰基合成丙烯酸、1,4-丁二醇系列產(chǎn)品的研究進(jìn)展。

Natural gas is important chemical material and is used as feed to produce synthesis ammonia,methanol and ethyne. 天然氣是化工的重要原料,以天然氣為原料生產(chǎn)合成氨、甲醇、乙炔三大產(chǎn)品。

Natural gas is important chemical material and is used as feed to produce synthesis ammonia, methanol and ethyne. 摘要天然氣是化工的重要原料，以天然氣為原料生產(chǎn)合成氨、甲醇、乙炔三大產(chǎn)品。

The other is special chemicals of ethyne, such as 1,4-butanediol series made by alkyne -aldehyde method, including ethynyl aether,polyacetylene,etc. 在石油價(jià)格居高不下的情況下,乙炔化工在某些領(lǐng)域?qū)⒕哂忻黠@的競爭優(yōu)勢。
