摘要： A method of producing methyl methacrylate comprising the following steps:
Thermal decomposition step: a hydrocarbon having 3 or more carbon atoms is thermally decomposed to obtain a decomposed gas having a total content of propyne and propadiene of 2 wt% or more,
Separation step: mixed liquid rich in propyne and propadiene is separated from the decomposed gas obtained in the thermal decomposition step,
Propyne purification step: the mixed liquid rich in propyne and propadiene obtained in the separation step is subjected to extractive distillation, for separation into purified propyne, and crude propadiene containing propadiene as the main component,
Isomerization step: the crude propadiene obtained in the propyne purification step is isomerized in the presence of an isomerization catalyst, to obtain crude propyne containing propyne as the main component, and
Carbonylation step: the purified propyne obtained in the propyne purification step is reacted with carbon monoxide and methanol in the presence of a group VIII metal catalyst system, to produce methyl methacrylate.摘要翻译： 一种生产甲基丙烯酸甲酯的方法，包括以下步骤：热分解步骤：将具有3个或更多个碳原子的烃热分解，得到丙炔和丙二烯的总含量为2重量％以上的分解气体，分离步骤：混合 从热分解步骤中得到的分解气体中分离富含丙炔和丙二烯的液体，丙炔纯化步骤：将在分离步骤中得到的富含丙炔和丙二烯的混合液进行萃取蒸馏，分离成纯化丙炔， 丙二烯含有丙二烯为主要成分，异构化步骤：丙炔纯化步骤中得到的粗制丙二烯在异构化催化剂存在下异构化，得到含有丙炔的粗制丙炔作为主要成分，羰基化步骤：将纯化的丙炔 丙炔纯化步骤与一氧化碳和甲醇反应， n存在第VIII族金属催化剂体系，生产甲基丙烯酸甲酯。

摘要： In a method for producing chlorine comprising oxidizing hydrogen chloride present in a gas containing the hydrogen chloride using a gas containing oxygen in the presence of a catalyst, an improvement which comprises conducting the oxidation of the hydrogen chloride in a reaction region comprising at least two catalyst-packed layers connected in series and carrying out the temperature control of at least one reaction region using a heat exchange system is disclosed. This method enables the inhibition of formation of excess hot spots and effective utilization of the catalyst-packed layers, which results in maintaining stable activity of the catalyst and in the production of chlorine in high yield with good stability.

摘要： A process for producing chlorine comprising the step of oxidizing hydrogen chloride in a gas containing hydrogen chloride with a gas containing oxygen in the presence of a catalyst, wherein the oxidation of hydrogen chloride is carried out in at least two reaction zones each comprising a catalyst-packed layer, which are arranged in series, and a temperature in at least one of said reaction zones is controlled with a heat exchange system. According to this process, the stable activity of the catalyst is maintained and chlorine can be stably obtained at a high yield since the excessive hot spot in the catalyst-packed layer is suppressed and the catalyst-packed layer can be effectively used.
