脂肪烃分子式：CAS号：性质：分子中只含有碳和氢两种元素，碳原子彼此相连成链，而不形成环的一类化合物。根据碳原子间键的种类——单键、双键、叁键，可分为烷烃或石蜡烃、烯烃、二烯烃、炔烃。含有双键或三键的叫作不饱和烃。碳链是直的叫作直链烃，有侧链的叫作侧链烃。烷烃的分子通式为CnH2n+2、烯烃为CnH2n、炔烃和二烯烃为CnH2n-2。脂肪烃的物理性质，例如沸点、熔点、相对密度等，随分子中碳原子数的递增而呈现出有规律的变化，常温下的状态则由气态逐渐变成液态、固态。主要化学性质为碳原子上的氢原子被其他活泼原子的置换反应、高温下断链、脱氢生成较低碳数的烷烃，烯烃的裂解反应。C6～C8直链烷烃可经脱氢环化生成苯系芳烃的反应。烯烃、二烯烃、炔烃的化学性质活泼，可以进行加成、置换、齐聚、共聚、聚合、氧化等多种反应，工业上最有用的是加成及聚合反应。脂肪烃一般都是石油和天然气的重要成分。C1～C5低碳脂肪烃是石油化工的基本原料，尤其是乙烯、丙烯和C4、C5共轭烯烃，在石油化工中应用最多、最广。
