  • Improved process for preparing unsaturated carboxylic acid esters and novel apparatus for preparing the same
    申请人:LUCKY LTD.
    公开号:EP0713857A1
    公开(公告)日:1996-05-29
    The present invention relates to a process for continuously preparing unsaturated carboxylic acid esters by esterifying an (aliphatic) alcohol having 1 to 8 carbon atoms with an unsaturated carboxylic acid in the presence of a cation exchange resin catalyst, characterized in that the process is conducted by continuously circulating said reactants in contact with said catalyst from the top to the bottom through a reactor which is composed in the form of a fixed bed divided into 1 to 10 steps wherein each step comprises a catalyst bed, a filter and a air inlet, and has a thermal insulating outer wall, supplying a vaporizing heat for extraction of water, which is produced during the reaction, through a heat exchanger outside the reactor, circulating the reactants between the reactor and the heat exchanger by means of a circulating pump, contacting an azeotropic mixture of water vaporized by the heat exchanger and an alcohol with an alcohol circulating in a column tower or a raw alcohol supplied from an alcohol inlet located on the top of the column tower to recycle the high boiling component into the reactor and, at the same time, to transfer the light component to the upper part of the column in which the light component is condensed, separating the condensate into an organic layer and water in a decanter, and then recycling the organic layer into the reactor and removing the water produced during the reaction, and a novel apparatus for carrying out this process.
    本发明涉及一种连续制备不饱和羧酸酯的工艺,其方法是在阳离子交换树脂催化剂存在下,将具有 1 至 8 个碳原子的(脂肪族)醇与不饱和羧酸酯化、该反应器以固定床的形式组成,分为 1 至 10 个步骤,其中每个步骤包括一个催化剂床、一个过滤器和一个进气口,并有一个隔热外壁,通过反应器外的一个热交换器提供汽化热以提取反应过程中产生的水、通过循环泵使反应物在反应器和热交换器之间循环,将热交换器蒸发的水和酒精的共沸混合物与在塔式塔中循环的酒精或从位于塔式塔顶部的酒精入口供应的原酒精接触,以便将高沸点组分回收到反应器中,同时将高沸点组分转移到反应器中、同时,将轻组分转移到塔的上部,轻组分在塔中冷凝,在滗水器中将冷凝物分离成有机层和水,然后将有机层回收到反应器中,并除去反应过程中产生的水,以及用于实施该工艺的新型装置。
