NSC 6571 - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| purpose | for organic synthesis of raw materials, solvents, extractants. |
| production method | a by-product obtained from N-pentyl chloride to N-pentanol or synthesized from sodium pentanol and bromopentane. In addition, using n-pentanol sulfuric acid dehydration method can also be prepared. This method is used in industrial production. Industrial amyl ether is a mixture of N-amyl ether and isoamyl ether, colorless or light yellow liquid, stable nature. Insoluble in water, soluble in methanol, ethyl ether, ethyl acetate, acetone, aliphatic or aromatic hydrocarbons, oleic acid, hot fatty acids, hot fat wax. Its mixture with ethanol differs from the lower ether in that it does not dissolve nitrocellulose, but a mixture of 80% pentyl ether and 20% ethanol dissolves ethyl cellulose. |
