年產(chǎn)500噸馬來酸二乙酯車間工藝設(shè)計 ——填料精餾塔的設(shè)計 摘 要：馬來酸二乙酯（DEM）是高分子化合物單體，農(nóng)藥、醫(yī)藥、香料、水質(zhì)穩(wěn)定劑（有機多元羧酸磷酸化合物）的中間體；本文總述了馬來酸二乙酯的性質(zhì)、用途、主要生產(chǎn)方法、市場前景及發(fā)展趨勢；介紹了年產(chǎn)500噸馬來酸二乙酯車間工藝中馬來酸二乙酯-馬來酸酐分離過程填料精餾塔的設(shè)計，根據(jù)物料衡算確定了填料精餾塔的工藝參數(shù)及塔體類型。 關(guān)鍵詞：馬來酸二乙酯-馬來酸酐；分離過程；填料精餾塔 The Process Design of a Plant Producing 500t/a Diethyl Maleate —The design of packing distillation column Abstract: Diethyl Maleate is a macromolecular monomer and intermediates of pesticide , medicine spices, water quality stabilizer(organic polybasic carboxylic acid phosphate compound). Its natures, uses, main production methods, the market prospect and the trend of development are mainly introduced in this paper. This paper introduces the design of packing distillation column in the annual output of 500 tons diethyl maleate process between diethyl maleate-maleic anhydride separation process , According to the material balance of the packing distillation column,the technological parameters and the tower body types were determined.. Key words: diethyl maleate - maleic anhydride ; separation process; packed column.
