Abstract: A method and system for preparing a mixture of Guerbet alcohols where one or more primary alcohols of the formula RCH2CH2OH are provided, with R representing hydrogen or a straight or branched chain alkyl group of 1 to 14 carbon atoms. A base and a catalyst are provided, which are mixed with the primary alcohol(s). The resulting mixture is heated to a process temperature above the boiling point of water under reaction conditions and the water resulting from the thus obtained condensation and dehydration of the primary alcohols is then removed constantly. When the Guerbet reaction has reached a certain stage, at least part of the reaction mixture is removed, followed by a separation of the desired Guerbet alcohols from the removed part of the reaction mixture. The other alcohols are then returned to the reaction mixture for obtaining a higher amount of the desired Guerbet alcohols.

Abstract translation: 制备其中提供了一种或多种式RCH 2 CH 2 OH的伯醇的格尔贝特醇的混合物的方法和系统,其中R表示氢或1至14个碳原子的直链或支链烷基。 提供碱和催化剂,其与伯醇混合。 将所得混合物在反应条件下加热至高于水沸点的工艺温度,然后由此获得的伯醇缩合和脱水产生的水不断地被除去。 当格伯特反应达到一定阶段时,至少部分反应混合物被除去,然后将所需的格尔伯特醇从反应混合物的去除部分分离出来。 然后将其它醇返回到反应混合物中,以获得更高量的所需的格尔伯特醇。
