What is Diisooctyl phthalate CAS 27554-26-3？

Diisooctyl phthalate, English name 2, 4-diethyl-9h-Thioxanthen-9-one, is a colorless oily liquid at room temperature and pressure, insoluble in water but soluble in dimethyl sulfoxide and alcohol organic solvents. Diisooctyl phthalate is a derivative of phthalic acid, which can be prepared by esterification of phthalic anhydride and isooctyl alcohol. The substance has good chemical stability and it shows good solubility to other organic compounds, and can be used as a solvent in chemical production and a plasticizer in the material industry.

Application

Diisooctyl phthalate has similar physical and chemical properties to benzoate, and it is mainly used as an organic solvent and plasticizer in the polymer material industry in chemical production. Plasticizer (plasticizer) is a polymer material additive, plasticizer added to the polymer material, without changing its basic chemical properties, reduce its melt viscosity, glass transition temperature and elastic touch, so as to improve its processability, and improve the product’s softness and tensile properties of the substance.
