Product Application of 1-Butanol CAS#71-36-3
1-Butanol is a fast-evaporating, high-efficiency organic solvent that exhibits strong dissolving capacity for resins, oils and organic compounds and features stable compatibility in various industrial formula systems. It is typically used in coating dilution, ink blending and esterification synthesis processes, with its solvent efficiency adjustable according to formula viscosity and solid content requirements.
In industrial production applications, 1-Butanol can be used as a key intermediate for manufacturing butyl acetate, plasticizers and synthetic resins. It is widely adopted in pharmaceutical extraction, textile auxiliary processing and adhesive production, and is commercially produced through industrial oxo synthesis and fermentation processes.
