    • A process for the production of an ether optionally with a diol and/or a lactone, by reaction of a corresponding organic feed material selected from unsaturated dicarboxylic acids and/or anhydrides, mono-esters of unsaturated dicarboxylic acids and/or anhydrides, diesters of unsaturated dicarboxylic acids and/or anhydrides, unsaturated lactones, and mixtures of two or more thereof in the presence of hydrogen which comprises the steps of-(a) supplying a stream comprising at least a portion of the organic feed material to a pre-reactor zone comprising catalyst and operating under reaction conditions and contacting said feed with a hydrogen containing stream such that at least some of the carbon carbon double bonds are saturated; (b) vaporising the at least partly saturated feed into the hydrogen containing stream in a vaporising zone; (c) supplying the hydrogen-containing stream containing the vaporised at least partially saturated feed to a reaction zone comprising catalyst and operating under reaction conditions; (d) recovering from the reaction zone a product stream comprising the ether and optionally diol and/or lactone; and (e)recycling depleted hydrogen-containing stream to at least the pre-reactor zone or the vaporisation zone.
    • 通过相应的选自不饱和二羧酸和/或酸酐的有机原料,不饱和二羧酸和/或酸酐的单酯和/或酸酐的二酯的二酯与二醇和/或内​​酯生产醚的方法 不饱和二羧酸和/或酸酐,不饱和内酯及其两种或多种在氢存在下的混合物,其包括以下步骤:(a)将包含至少一部分有机原料的料流供应至预反应器 区域,其包含催化剂并在反应条件下操作并使所述进料与含氢气流接触,使得至少一些碳碳双键饱和; (b)将蒸气区中的至少部分饱和的原料汽化成含氢气流; (c)将含有蒸发的至少部分饱和的进料的含氢流供应到包含催化剂并在反应条件下操作的反应区; (d)从反应区回收包含醚和任选的二醇和/或内​​酯的产物流; 和(e)将耗尽的含氢流循环至至少预反应器区或蒸发区。
