Among ethers, n-butyl ether has strong solubility and has strong solubility in many natural and synthetic oils, resins, rubber, organic esters, alkaloids, etc. The solubility of butyl ether in water (20 ℃) is 0.03% by weight, and the solubility of water in butyl ether (20 ℃) is 0.19% by weight, indicating good separability with water. During storage, it generates less peroxide, has low toxicity and danger, and is a highly safe solvent. Used as an extraction and refining solvent for resins, oils, organic acids, esters, waxes, alkaloids, hormones, etc; A 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 an organic synthesis reaction solvent for Grignard reagent, rubber, pesticide, etc.
