Abstract

An examination is made of the relationship between the compositions of the dielectric fluids diarylethane 1-phenyl-1xylyl-ethane (PXE) and their toxicity. There are four isomers in PXE: OPXE, PPXE, EPXE, and MPXE. Their physical, chemical, and electrical properties are basically the same except that the flash point of OPXE is higher and the viscosity of EPXE is lower. The order of acute oral toxicity of the four isomers is MPXE>OPXE>PPXE>EPXE. The acute associated toxicity of their mixture containing two or more isomers shows an additive effect
