Application | used as solvent, electronic grade cleaning agent and organic synthesis used as solvent, electronic grade cleaning agent, organic synthesis among ethers, n-butyl ether has strong dissolving power for many natural and synthetic oils, resins, rubbers, organic acid esters, alkaloids, etc. The solubility of butyl ether in water (20 ° C.) was 0.03% by weight, and the solubility of water in butyl ether (20 ° C.) was 0.19% by weight, and the separation from water was good. In the storage of the formation of less peroxide, toxicity and risk of small, is a highly safe solvent. A mixed solution of a resin, a fat, an organic acid, an ester, a wax, an alkaloid, a hormone, and the like; And butyl phosphate can be used as a solvent for separating rare earth elements. Since butyl ether is an inert solvent, it can also be used as a reaction solvent for organic synthesis of Grignard reagents, rubbers, pesticides, and the like. used as reagents, solvents and extractants for the determination of bismuth solvents for fats and oils and hydrocarbons. Organic Synthesis. Extractant. |
production method | 1. From the dehydration of n-butanol with sulfuric acid, butanol and sulfuric acid were added to the reaction pot, heated and stirred, and the temperature was raised to about 110 ° C. To start reflux, and water was separated. As the reaction proceeds, water is continuously separated, and the temperature is gradually increased, and the reaction is basically completed when it reaches 135 °c. Washing with water, washing with sulfuric acid, washing with water again, drying with anhydrous calcium chloride, distillation, and collecting the distillate at 139-142 ° C. To obtain butyl ether. N-Butanol is prepared by catalytic dehydration on ferric chloride, copper sulfate or aluminum oxide. Purposes: In ethers, n-butyl ether dissolution of many natural and synthetic oils, resins, rubber, organic acid esters, alkaloids have a strong dissolution. The solubility of butyl ether in water (20 ° C.) was 0.03% by weight, and the solubility of water in butyl ether (20 ° C.) was 0.19% by weight, and the separation from water was good. In the storage of the formation of less peroxide, toxicity and risk of small, is a highly safe solvent. Used as resin, oil, organic acids, esters, waxes, alkaloids, hormones and other extraction and refining solvent; The mixed solution with butyl phosphate can be used as a solvent for separating rare earth elements. Since butyl ether is an inert solvent, it can also be used as a reaction solvent for organic synthesis of Grignard reagents, rubbers, pesticides, and the like. |
