\u002F>①氢氧化钠法：此法又可分为两种类型，一是全部反应在一个连续反应器中进行，配料比(NaOH:CH2ClCHCl2)为(1-1.2:1)，氢氧化钠的含量为10%-20%，反应温度在50-70℃，产品含量为94%，收率为93.9%，二是用含氯化钠的氢氧化钠，使用1,1,2-三氯乙烷转化成偏二氯乙烯。此法直接采用电解液，而且脱氯化氢后生成的氯化钠可返回电解系统循环使用。因此，最适合于氯碱厂生产偏二氯乙烯。\u003Cbr \u002F>②氢氧化钙法：此法又可分为四种类型。其一，原料氢气化钙浓度为200g\u002FL，碳酸钙浓度＜20g\u002FL，氢氧化钙过量50%，反应开始时体系温度为80℃，然后升至90-92℃。反应结束后得到的粗偏二氯乙烯，经蒸馏提纯，收率可达80％以上。其二，由于生成偏二氯乙烯反应的控制步骤为界面上的物质转移，所以要加入少量表面活性剂和水提高接触效果。其三，为简化工艺，将反应和蒸馏合并在一个塔内进行。其四，先将氯乙烯和氯气通过反应器进行加成反应，再加10%的氢氧化钙，使1,1,2-三氯乙烷转化成偏二氯乙烯，精制后即得产品偏二氯乙烯。\u003Cbr \u002F>③氢氧化铵法：旭道公司提出用氢氧化铵代替氢氧化钠和氢氧化钙，投料比为NH4OH：CH2ClCHCl2=2:1(mol)，反应温度为120℃，压力约为0.86MPa，转化率为52.1%，氯化铵、氨和未反应的1,1,2-三氯乙烷可循环使用。氯化反应在塔式反应器内进行，塔内充有三氯乙烷，用铁环堆砌塔内作催化剂，氯气和氯乙烯按配比1.05：1（mol)从塔底通入，反应温度控制在35-45℃。由于氯乙烯与氯气反应液可以依靠温度差进行自然循环，也可以用泵进行了强制循环。反应温度约75℃，压力为常压，生成的偏二氯乙烯经釜上的粗分塔，再经精馏塔提纯提精产品偏二偏乙烯。目前国内诸厂均采用釜式碱解反应器，大多为间歇操作。过去曾有人使用2.5%-3.0%的石灰乳作碱液，后因堵塞设备而改用稀氢氯化钠溶液。在间歇操作中，碱解后期将反应温度升至85℃，结果是粗偏二氯乙烯的杂质明显增多，给精制带来困难。\u003C\u002Fp>\u003Cp>2.氯乙烷氯化碱解法：该法采用1,2-二氯乙烷为原料，在温度118℃，压力4.6MPa下，经液相氯化成1,1,2-三氯乙烷，反应物除1,2-二氯乙烷和氯气外，还加入12%乙烯，以加速二氯乙烷 的氯化反应。三氯乙烷经低沸塔和高沸塔提纯后与稀碱反应，脱除一分子氯化氢制得偏二氯乙烯；粗偏二氯乙烯经低沸塔、高沸塔精制得纯偏二氯乙烯产品。上述工艺氯化产率95.4%，碱解收率99.8%，产品纯度高达99.9%。\u003C\u002Fp>\u003Cp>3.甲基氯仿热裂解氯化氢法：此法采用氯乙烯为原料，与氯化氢加成生成1,1-二氯乙烷；二氯乙烷在480℃高温下氯化，所得氯化液产物主要有偏二氯乙烯、甲基氯仿（1,1,1-三氯乙烷）及氯乙烯。副产物有三氯乙烯、顺式二氯乙烯、反式二氯乙烯、多氯乙烷及氯化氢。氯化液经精馏将上述产物分离，氯乙烯和氯化氢返回加成工序，三氯乙烯作为商品出售，甲基氯仿经高温裂解成偏二氯乙烯，裂解混合物与氯化液合并精馏分离，偏二氯乙烯中加入阻聚剂作为商品出售，1,1-二氯乙烷与1,2-二氯乙烯经液相低温氯化成1,1-二氯乙烷与四氯乙烷，再送入高温氯化器。\u003C\u002Fp>\u003Cp>4.乙烷氯化、热裂解脱氯化氢法：此法采用乙烷为原料，在高温426.6℃下氯化成含氯化氢、氯乙烯、偏二氯乙烯、氯乙烷、1,1-二氯乙烷和甲基氯仿的混合物，用分馏方法将上述产物分开。氯化氢用于氯乙烯氢氯化反应器；甲基氯仿经高温裂解除一分子氯化氢生成偏二氯乙烯，与氯化液合并进行分离提纯，获高纯产品偏二氯乙烯。\u003C\u002Fp>\u003Cp>5.高温热脱氯化氢法：先将1,1,2-三氯乙烷预热至250℃，然后通入管式反应器进行分解反应。反应温度为350-500℃。本法的优点是分解产物氯化氢可以利用，但副产物1,2-二氯乙烯较多。\u003C\u002Fp>","\u003Ctd>\n\n\u003Ctable>\n\u003Ctbody>\n\u003Ctr>\n\u003Ctd>\u003Cstrong>
