Abstract:
... Trichlorobenzene is a mixture of three isomers which are 1,2,3-trichlorobenzene, 1,2,4-trichlorobenzene and 1,3,5-trichlorobenzene. Due to the boiling points of the three components are close to each other, the adoption of conventional distillation process requires a large amount of energy. To reduce the distillation energy consumption, heat integration technology and mechanical vapor recompressio ...

Abstract:
... Atmospheric nitrate (NO₃⁻) produced by photochemical oxidation in the atmosphere has high oxygen isotope ratios (δ¹⁸O values). Recently, the primary NO₃⁻ emitted from combustion sources was found to have much lower δ¹⁸O values. However, it is unclear how and to what extents the low δ¹⁸O signatures were controlled by major O sources during the primary NO₃⁻ formation of combustion processes. Here, w ...
