乙炔乙炔acetylene最简单的炔烃。分子式HC≡CH。无色有芳香气味的易燃气体。熔点-80.8℃,沸点-84℃,相对密度0.6208(-82/4℃)。在液态和固态下或在气态和一定压力下有猛烈爆炸的危险,受热、震动、电火花等因素都可以引发爆炸,因此不能在加压液化后贮存或运输。难溶于水,易溶于丙酮,在15℃和总压力为15大气压时,在丙酮中的溶解度为237克/升,溶液是稳定的。因此,工业上是在装满石棉等多孔物质的钢桶或钢罐中,使多孔物质吸收丙酮后将乙炔压入,以便贮存和运输。乙炔分子中的两个π键和空气的混合物在乙炔含量2.5%~80%范围内有爆炸性。如供给适量空气,可以安全燃烧而发白光,在没有电源的地方用作光源。在氧气中燃烧,氧炔焰的温度高达3200℃左右,可用来切割和焊接金属。化学性质很活泼,易起加成反应,生成多种重要的化工产品。在氯化汞存在下与氯化氢加成,生成氯乙烯:HC≡CH+HCl→H2C=CHCl在乙酸锌存在下与乙酸加成,生成乙酸乙烯酯:HC≡CH+CH3COOH→H2C=CHOCOCH3在羰基镍存在下与一氧化碳和水或醇作用,生成丙烯酸或丙烯酸酯,氯乙烯、乙酸乙烯酯、丙烯酸和丙烯酸酯都是生产高聚物的原料。乙炔分子中的氢有微弱酸性,可被金属取代生成乙炔化物,例如将乙炔通入亚铜盐或银盐的氨水溶液中,立即沉淀出红棕色的乙炔亚铜CuC≡CCu,或乙炔银AgC≡CAg,此反应可用于乙炔的定性检验。工业上由甲烷部分地燃烧,甲烷或低级烷在高温下热解,或碳化钙(电石)水解生产。由碳化钙制备的乙炔由于含磷化氢等杂质而有恶臭。
