氧氯化硫制备

1.氯磺酸法先将硫黄粉加入反应器中，通入氯气进行反应生成一氯化硫。再将一定量的氯磺酸和一氯化硫加入反应器内，在50℃以下通入氯气进行反应，反应好的物料经粗馏、冷凝，收集130℃以下的料液送至精馏锅，为了使低沸点的二氯化硫转变成一氯化硫留在锅内，则要加入粗品数量的15%～20%硫黄，然后送去精馏，经回流4h，色泽正常后，收集气相75～80℃的馏分，制得亚硫酰氯成品。其反应方程式如下：

2.二氧化硫法以硫黄、液氯和液体二氧化硫为原料，采用全循环和液相循环法，生产高纯度氯化亚砜矾，纯度99%以上，该方法工艺先进，产品质量稳定，“三废”排放少。

图XVI-4 制备SOCL2的制备

二氯亚砜也叫亚硫酰二氯或氯化亚硫酰。

图制备SOCl2的装置

1—烧瓶1；2—烧瓶2；3—密封磨口

(1).在如图所示的烧瓶1中加入纯净的发烟硫酸，在烧瓶2中加入SCl2。慢慢加热烧瓶1，并用冰水冷却烧瓶2，SO3进入SCl2中即开始发生反应，放出的SO2通过通风柜排出。当反应完成后将1拆除并密封磨口3，在隔绝湿气的条件下慢慢进行蒸馏。然后在中间馏分中加入硫，仔细地分馏数次。获取76～77℃完全无色的馏分为最后产品。

(2).用一装有回流冷凝管的250mL双口烧瓶作反应器，反应器经彻底干燥后放入100g PCl5。冷凝管的上端联接一支CaCl2干燥管，在反应器的另一口中插入一根导气管至瓶底。从导气管中通入经仔细干燥过的SO2气体，摇荡反应瓶以加速反应进行。数小时后，PCl5全部溶解，反应即完成。用高效能的分馏柱仔细分馏产物数次，可得SOCl2产品。

精制方法：工业品的亚硫酸（二）氯中常含有硫酰氯、一氯化硫和二氯化硫等杂质，一般重蒸一次即可使用，但仍带有黄色。若需高纯度的产品，可将450mL亚硫酰（二）氯与12.5g硫加热回流4.5小时，然后用高效分馏柱分馏两次可得无色纯品。也可在亚磷酸三苯酯存在下进行蒸馏精制。

3.在干燥的五氯化磷中通入干燥的二氧化硫气体，在搅拌下边回流边反应，反应放出的热量将五氯化磷熔融：

待五氯化磷完全熔融后，加热混合物并搅拌均匀。然后精馏混合物数次，收集77～80℃馏分，即得试剂氯化亚砜。
