氢化三联苯是一种新型的化工工业中热媒,广泛应用于石油化工及化纤产品生产中。常温下为淡黄色液体,是三联苯部分加氢制的一种热稳定物质,故用作热载体。目前国内未制定其卫生标准和检测方法,为了满足现场测定的需要,研究了本方法。可用炭管采样,便于携带,方法简单,快速,灵敏。
Hydrogenated terphenyl is a new type of chemical industry in the heat medium, widely used in petrochemical and chemical fiber products. Room temperature is a light yellow liquid, is part of the terphenyl hydrogenation of a thermally stable material, it is used as a heat carrier. At present, China has not formulated its health standards and testing methods, in order to meet the needs of field measurement, the method has been studied. Available carbon tube sampling, easy to carry, the method is simple, fast and sensitive.
