Use: 1-Pentanol can be used as solvent, organic synthesis raw material and plasticizer raw material, and can also be used in the production of food flavors, flavors, pharmaceutical raw materials, flotation agents for non-ferrous metals, and antifoaming agents for boiler water. In industry, it is also the main raw material for the production of pentene, amylamine and bromopentane.

Production method:
1. Pentane mixture: The pentane fraction is dehydrated by anhydrous hydrogen chloride and mixed with chlorine gas at a temperature of 120-300 ℃. The product is cooled and distilled, and then the chlorinated pentane is hydrolyzed with sodium hydroxide aqueous solution as a catalyst. The crude pentanol is separated from water, and distilled to obtain pentanol containing 59% primary alcohol, 36% secondary alcohol, and 5% tertiary alcohol. According to reports, the United States mainly uses this method for production.
2. Chemicalbook carbonylation synthesis of carbon tetraenes. After treatment with 65% sulfuric acid, carbon tetraenes are carbonyled using cobalt salts as catalysts. The water gas pressure is 14.7-19.6 MPa, and the reaction temperature is 140-170 ℃. The carbonylation reactants are treated with hydrogen gas or dilute sulfuric acid to decompose carbonyl cobalt into metallic cobalt. They are reduced at a hydrogen pressure of 17.7-19.6 MPa and a temperature below 180-200 ℃, and then separated and refined to obtain pentanol.
