flash distillation
2.Using Flash Distillation-Capillary Gas Chromatography-Mass Spectrometry to Analyze the Volatile Compnents in Chinese Herbal Medicines(Ⅲ)
3.Based on the analysis on risk factors in the production system of polypropylene workshop in a chemical plant,the fire explosion risk in such main dangerous units as polymerization and flash distillation,raw material refining,tail gas reclaim and northern zone of canned propylene is assessed by the application of the method of Dow Fire Index V.7.0.And according to the result of the assessment,safety countermeasures for accident prevention are put forward.
4.EMMED 32 is a careful selection of distillation range during periling to give a low volatility and high flash point.
5.Because the carbonyl in its structure is with strongly absorb-electron effect, so it is a kind of non-proton polarity solvent with high boiling point, high flash point and low melting point, use conveniently for many processing operation such as filtration, distillation, solvent extraction, and so on; it is with very low toxicity, so the harm to human body is inappreciable, and reduce the environment pollution; due to its very strong dissolvability, it can dissolve organic matter, inorganic matter, resin, polymer, etc., and activate all kinds of reagent, mix to dissolve the other high boiling point solvents; it is with very good stability, it is stable under the hot strong alkali and acidity condition, it is with water-resistance and light, oxygen stability.
