我厂石油酯、氯化石油酯在磺氯酰化和氯化工序上投产以来一直采用光化法。在光源的选择上,曾先后使用过紫外光灯、高压汞灯,今年以来又试用了黑光灯,情况良好,反应速度、耗电量、投资费用、操作控制和安全生产等各方面均优于紫外光灯和高压汞灯,现已正式应用于大生产中。光化反应在一定的光强范围内,决定于光的波长。磺氯酰化、氯化反应中参与反应的SO_2和Cl_2在光波波长3000～3600A时较易离解。黑光灯的波长约为3600A,可能还有部分能促使SO_2和Cl_2离解的可见光,因此可推广试用于类似的光化反应。
Our petrochemical ester, chlorinated petroleum ester has been used photochemical method since it was put into production in the process of sulfochlorination and chlorination. In the choice of light source, has used UV light, high pressure mercury lamp, this year has tried black light, good condition, reaction speed, power consumption, investment costs, operation control and safety in all aspects are better than UV light and high pressure mercury lamp, is now officially used in large-scale production. Photochemical reaction in a certain light intensity range, depending on the wavelength of light. Sulfonyl chloride, chloride reaction involved in the reaction of SO_2 and Cl_2 in the light wavelength 3000 ~ 3600A easier to dissociate. The black light has a wavelength of about 3600A, and there may be some visible light that can promote the dissociation of SO2 and Cl2. Therefore, it can be extended to a similar photochemical reaction.
