| Physical and Chemical Properties | Pentanol, chemical formula C5H11OH. Molecular weight 88.15. There are eight isomers. All were colorless liquids except for 2, 2-dimethyl-1-propanol which was solid. Three of them are derivatives of n-pentane, four are derivatives of isopentane and one is a derivative of Tetramethylmethane. The fusel oil contains 3-methyl-1-butanol, I .e., isoamyl alcohol, and 2-methyl-1-butanol, I .e., optically active pentanol. 3-methyl-1-butanol is a colorless liquid with an unpleasant odor, toxic! Density 0.813(15 ° C), melting point -117 ° C, boiling point of 132 ° C, slightly soluble in water, and ethanol and ether miscible, mainly used as a solvent and preparation of drugs. 2-methyl-1-butanol is colorless liquid, density 0.816, boiling point 128 ℃, slightly soluble in water, miscible with ethanol, ether, levorotatory body [α]D20-4.75 °. Esters of amyl alcohol (e. G., amyl acetate) may be used as a perfume or solvent. |

pentan-1-ol - Reference Information
| introduction | pentanol is a colorless liquid with a slight odor, slightly soluble in water, and miscible in most organic solvents such as ethanol and ether. |
| use | pentanol can be used as organic synthesis, as coating solvent, raw material for medicine, flotation agent for non-ferrous metals, anti-foaming agent for boiler water, and can be used to make amyl acetate. The mixture of pentanol and other solvents can be used as a co-solvent for nitro painting, and is also used to extract turpentine from wood. |
| toxicity | pentanol is a low toxicity category. The oral LD50: 3-pentanol in rats is 1.87 g/kg. 2-methyl -2-butanol 1g/kg. No death was seen in rats exposed to 28.8g/m3 (near-saturated vapor) pentanol. Rabbit skin absorption (24h contact) 3-pentanol LD502.52ml/kg. After inhaling amyl alcohol vapor, people may have symptoms of eye and upper respiratory tract irritation, headache, dizziness, dyspnea, vomiting, diarrhea, diplopia, delirium, etc. Multiple oral poisoning in rabbits can cause liver damage. A few rats were given isoamyl alcohol orally or subcutaneously to show an increase in malignant tumors. |
| spontaneous combustion temperature | 340°C |
