随着我国石油化工工业的发展和需要,破乳剂的生产已有近廿年的历史,但生产过程中,如能对各种有害气体进行监测,以便为劳动保护和予防措施提供必要的资料。从而保证职工的身体健康和四化建设的顺利进行,当前具有重要的意义。自1978年报告了破乳剂车间空气中环氧乙烷和环氧丙烷的气相色谱测定外,尚未见有对其他有害气体的测定报告,为此我室对破乳剂车间氯化中和工序副反应生成的氯乙烷、氯丙烷进行了气相色谱分析方法的探讨,由于这些有害气体在大气中含量甚微,一般都要先经过浓缩
With the development and needs of the petrochemical industry in our country, the demulsifier has been produced for nearly 20 years. However, during the production process, various harmful gases can be monitored to provide necessary information for labor protection and preventive measures. In order to ensure the health of workers and the smooth progress of the four modernizations, it is of great significance at present. Since the report of the gas chromatograph of ethylene oxide and propylene oxide in the air of demulsifier workshop has been reported since 1978, no report on the determination of other harmful gases has yet been found. For this reason, our laboratory has no side reactions to the chlorination and neutralization of the demulsifier workshop The generated chloroethane, chloropropane gas chromatographic analysis of methods, due to the content of these harmful gases in the atmosphere is very small, generally have to be concentrated
