查询词典 terephthalic acid

In order to give sufficient data support for the design of terephthalic acid manufacture, corresponding phase equilibria, including solid-liquid equilibrium and vapor-liquid equilibrium, have been determined and studied.Improvements have been made on our former apparatus, which was used for the measurement of solid solubility, for the purpose of getting more precise experimental data in the range of lower solubility. Horizontal stir was changed to magnetic whirly one, which shortened the dissolving time remarkably.
