n indane, tetralin or phenyl alcohol is made by a heterogeneous, fast, exothermic Friedel Craft reaction and the reaction mixture is cooled to a temperature at which substantial by-product formation is avoided by continuously utilising the heat of reaction to boil solvent from the reaction mixture. The reaction mixture is generally maintained below atmospheric pressure, typically 20 to 100 mm Hg. The process is of particular value for the production of aryl alcohols by reacting an indane or tetralin with ethylene oxide or propylene oxide.
茚、四萘或苯基醇是通过一个异相、快速、放热的弗里德尔克拉夫特反应制得的,反应混合物被冷却到一个温度,在这个温度下,通过不断利用反应热来沸腾反应混合物中的溶剂,可以避免大量副产物的生成。 反应混合物通常保持在大气压以下,一般为 20 至 100 毫米汞柱。 通过茚或四萘与环氧乙烷或环氧丙烷反应生产芳基醇,该工艺具有特殊的价值。
