Main Uses

Solvent:

Due to its good solubility for resins, oils, dyes, etc., it is widely used in coatings (nitrocellulose lacquers, alkyd paints), adhesives, and printing inks to adjust system viscosity and promote film formation.

As an extractant, it is used in the pharmaceutical and fragrance industries to extract natural ingredients (such as essential oils and alkaloids).

Chemical Raw Material:

Production of plasticizers: Reacts with phthalic anhydride to produce dibutyl phthalate (DBP), used in polyvinyl chloride (PVC) plastics to enhance flexibility.

Production of esters: Reacts with acetic acid to produce butyl acetate (a solvent used in coatings and fragrances); reacts with acrylic acid to produce butyl acrylate (a synthetic resin monomer).

Production of chemicals such as butyl ether and butylamine, used in organic synthesis or surfactants.

Other Fields:

In the pharmaceutical industry, as a solvent or reaction medium for drug intermediates;

In cosmetics, as a humectant or solvent (such as in nail polish and perfumes);

Small amounts used as fuel additives (to improve diesel fluidity) or defoamers.
