用具有8-18个碳原子的脂族单烯烃化合物将芳族化合物烷基化的方法和装置
Abstract:
本发明公开了使用至少三个串联反应区(104、106a、106b)以包含每分子有8－18个碳原子的脂族烯烃的脂族原料对芳族化合物进行单烷基化的连续方法，每个反应区包含固体烷基化催化剂，流出物在反应区(104、106a、106b)之间冷却，向每个反应区供给一部分新鲜脂族原料，使得每个反应区(104、106a、106b)中的反应区ΔT低于15℃。总的芳族化合物与烯烃的摩尔比低于20∶1。即使使用低芳族化合物与烯烃摩尔比，烷基化产物仍然有所期望的线性和低量二聚体、脱烷基化化合物和二芳基化合物。
Abstract(English):

Continuous processes for monoalkylating aromatic compound with an aliphatic feedstock comprising aliphatic olefin of 8 to 18 carbon atoms per molecule are effected using at least 3 reaction zones (104, 106a, 106b) in series, each containing solid alkylation catalyst with effluent cooling between reaction zones (104, 106a, 106b), each of which reaction zones is supplied a portion of the fresh aliphatic feedstock, such that the Reaction Zone Delta T in each reaction zone (104, 106a, 106b) is less than 15 DEG C. The overall aromatic compound to olefin molar ratio is less than 20:1. The alkylation product has desirable linearity and low amounts of dimers, dealkylated compounds and diaryl compounds even though a low aromatic compound to olefin molar ratio is used.
