environmentally friendly solvent | methyl cyclohexane, also known as cyclohexyl methane, is a colorless organic solvent and solvent, can partially replace benzene and ketones. It has a fragrant smell, low toxicity, and skin contact will cause redness, dryness and other phenomena. It is soluble in ethanol, ether, benzene, acetone, etc., insoluble in water, can be widely used in coatings, rubber, Varnish solvent (some solvent also use methyl cyclohexane), it can be used as a fat extraction agent and the like. Methyl cyclohexane can also be used in organic synthesis, as a solvent and analytical reagent. In addition, methylcyclohexane can also be used as a standard for calibration thermometers. Methyl cyclohexane has good stability, the storage needs to be sealed independent storage, the most easy to store in winter under low temperature conditions. |
application field | methyl cyclohexane is an environmentally friendly coating, mainly used in solvents for ink, rubber, paint and varnish, oil extraction solvent, chromatographic analysis of standard substances, can also be used in organic synthesis, etc.; Do solvent and Analytical reagents. |
Use | used as solvent for rubber, paint, varnish, oil extraction solvent, etc.; The product can also be used in organic synthesis; used as a standard for calibration thermometers. used as solvent and analytical reagent is an important organic solvent and extractant, widely used in rubber, paint, grease and other industries, also used in organic synthesis used as solvent, standard substances for chromatographic analysis, as well as standards for calibration thermometers, are also used in organic synthesis |
production method | toluene was hydrogenated at 150 ° C. Under a pressure of about 11MPa for 5h, and relatively pure methylcyclohexane was added. When refining, it can be washed sequentially with concentrated sulfuric acid, water, 5% sodium hydroxide solution and water, dried with dehydrating agent, and finally distilled. |
