dibutyl phthalate; Di-n-butyl phthalate; n-Butyl phthalate; Butyl phthalate

Dibutyl phthalate is a phthalate ester that is the diester obtained by the formal condensation of the carboxy groups of phthalic acid with two molecules of butan-1-ol. Although used extensively as a plasticiser, it is a ubiquitous environmental contaminant that poses a risk to humans. It has a role as an environmental contaminant, a teratogenic agent, a plasticiser, a metabolite and an EC 3.2.1.20 (alpha-glucosidase) inhibitor. It is a phthalate ester and a diester. It derives from a butan-1-ol.

Dibutyl phthalate is a plasticizer with strong dissolving power for various resins.It is mainly used in the processing of polyvinyl chloride (PVC), imparting good flexibility to products.Due to its relatively low cost and good processability, it is widely used domestically, almost equivalent to DOP.However, it has relatively high volatility and water extractability, resulting in poor durability of the final products, so its use should be gradually restricted.It can also be used in the manufacture of paints, adhesives, artificial leather, printing inks, safety glass, celluloid, dyes, pesticides, perfume solvents, textile lubricants, etc.
