Biphenyl oxide
WebDowtherm ® A is a thermally stable organic heat transfer fluid composed of a eutectic mixture of highly stable compounds, biphenyl, and diphenyl oxide. Dowtherm ® A is suitable for high-temperature heat transfer applications up to 400 °C. This fluid can be used in both liquid and vapor phase systems. WebThe relative standard deviation (RSD, n = 4) for 5.0 µg L −1 of analytes were 8.4% and 6.7% for biphenyl and biphenyl oxide, respectively. The relative recoveries of biphenyl and biphenyl oxide from sea, river water and refined water (Paksan company) samples at spiking level of 5.0 µg L −1 were between 85.0% and 100 %.
