16m^3蒸馏釜生产氯化亚砜工艺

Production process of thionyl chloride in 16m^3 distillation kettle

介绍中平能化开封东大化工有限公司采用16 m3蒸馏釜生产氯化亚砜的情况,最佳工艺参数为:0.5MPa蒸汽,加热至80℃,全回流时间为3～4 h,采出时间为10～12 h,初馏分采出时间为1.5～2 h。

The production situation of thionyl chloride in 16 m^3 distillation kettle at Kaifeng Dongda Chemical Industry Co. , Ltd. is introduced. The optimum process parameters are as follows： heating to 80 ℃ by 0.5 MPa steam followed by infinite refluxing for 3- 4 h, and then collecting fraction for 10- 12 h with the initial fraction （ 1.5- 2 h） recycled to distillation.
