It is a solvent for a variety of coatings and a raw material for preparing dibutyl phthalate, a plasticizer. It is also used in the manufacture of butyl acrylate, butyl acetate, ethylene glycol butyl ether, as an extractant for organic synthesis intermediates and biochemical drugs, and in the manufacture of surfactants.N-butanol is a colorless, transparent and alcoholic liquid.

Dissolving function: soluble in water and some solvents, such as ethanol/water, propanol/water in appropriate proportions. The aqueous solution has surface activity. High transparency and stable function. Different standard products have different gel temperatures and solubility changes with viscosity. The lower the viscosity, the greater the solubility. Different standards of HPMC have different functions. The dissolution of HPMC in water is not affected by pH.
