traits Description : almost insoluble in water transparent liquid. -98 ° C melting point, boiling point of 142 ° C (3.2kPa), the relative density of 0.7704 (20 / 4 ° C), the refractive index of 1.3992. Flash point (open cup) 30.6 ° C, thermal evaporation 288kJ/kg, viscosity 0.741mPa s (15 ° C), surface tension 23.4mN / m (15 ° C). With ethanol; Compatibility ether, acetone soluble. The more stable. Similar fruit smells slightly irritant. Combustion can produce extremely irritating compounds.

production methods : 1. Butanol by sulfuric acid generated from dehydration to alcohol, sulfuric acid 11:50, heating, stirring the temperature rose to around 110 ° C return, and the separation of water. As the reaction proceeded, the separation of continuous moisture, temperature gradually increased to reach 135 ° C reaction basically completed. Water washed, acid washing, washing with water, anhydrous calcium chloride drying, distillation, collecting 139-142 ° C distillate, in ether.

2. Butanol in ferric chloride; Copper sulfate or aluminum oxide on catalytic dehydration of admission.

purposes : the ethers, ether is a strong solution for many natural and synthetic oils, resins, rubber, organic acids, such as alkaloids have a strong edge dissolved.

water solubility (20 ° C) to 0.03% (weight), water solubility of the right-butyl ether (20 ° C) to 0.19% (weight), with good water separation. The storage peroxide generated less toxic and dangerous small, high-security solvent. For resins, oils, organic acids, esters, and wax, alkaloids, hormones such as solvent extraction and refining; N-butyl phosphate and the mixed solution can be used as a solvent separation of rare earth elements.

because it is inert solvent ether, also used Grignard reagent, rubber, pesticides and other organic synthesis reaction solvent.
