Propylene, also known as propene, is an unsaturated organic compound with the chemical formula CH3CH=CH2. It has one double bond, and is the second simplest member of the alkene class of hydrocarbons.

丙烯 （英語： Propene， 分子式： C 3 H 6），是一種无色 可燃气体，可以通过 石油 裂解 而获得。 在各种 烯烴 结构中，丙烯为仅次于 乙烯 较为简单的烯烃结构。 在大量運輸時，使用加壓 液化。 丙烯的 饱和蒸汽压 在25℃時為1158 kPa （華氏度千帕）。 在 室温 和 标准大气压 下，丙烯是无色的气体。 并且和许多其它 烯烃 一样，丙烯带有一种较淡但令人不適的气味。 [1] 由于丙烯的分子量大于 乙烯，所以丙烯具有高于乙烯的密度和沸点。 丙烯的沸点略低于 丙烷，所以丙烯 …

丙烯是一种无色、无臭、略带甜味的极度易燃气体，燃烧时会产生明亮的火焰，具有较低的爆炸极限（2%～11.1%）, [6-7] 在水中溶解度较低，但可溶于乙醇、乙醚等有机溶剂。 丙烯是重要的化工原料，主要用于生产聚丙烯，此外还可合成丙烯腈、环氧丙烷、异丙醇、苯酚、丙酮等化学品，广泛应用于塑料、医药、农业等领域。 [1] 丙烯的生产方式主要包括石油裂解和天然气裂解。 尽管丙烯的产业应用广泛，但根据世界卫生组织国际癌症研究机构（IARC），丙烯被列为3类致癌 …

Propylene, also known as propene, is a colorless gas that is essential in the industrial chemistry world. This flammable material plays a pivotal role in creating some of the most commonly used products in today’s society. In this article, we explore the origin, properties, and applications of this significant chemical compound.

Propylene is a gaseous compound obtained by the thermal cracking of ethane, propane, butane, and the naphtha fraction of petroleum. Like ethylene, it belongs to the “lower olefins,” a class of hydrocarbons whose molecules contain a single pair of carbon atoms linked by a double bond.

丙烯是烯烃同系列中第二个成员，结构简式CH2＝CHCH3，是仅次于乙烯和苯的重要有机工业原料。 一般由热裂化和催化裂化气体中分离出，也是轻油裂解制乙烯时的副产物。 分子中含有不饱和的碳碳双键，可与氢气、卤素、卤化氢等发生加成反应，也可发生加聚反应。 是生产丙烯腈、聚丙烯、乙丙烯橡胶、氧化丙烯、丙酮等合成树脂、合成橡胶、合成纤维和塑料的原料。 有麻醉和窒息急性中毒作用。 与氧混合时表现为麻醉性，与空气混合时窒息性比麻醉性强。 在30～40%浓 …
