This is a kind of colourless oily liquid, with little fragance. And it is complete soluble in ethanol and diethyl [ethyl] ether and soluble in  acetone, benzene and other organic solvent while insoluble in water. Besides, it is stable and combustible and then incompatible with strong oxidizing agents, strong acids, alkalies. While dealing with this chemical, avoid contact with skin and eyes, and you could also obtain more safety information from WGK Germany  2.

As for its usage, it is widely applied in many fields. It could be used as the fixative for spice and the plasticizer for alkyd resin, NBR, chloroprene rubber; it could also be as the rodenticide intermediate, such as diphacinone, pindone and Rozol and also the important dissolvant; it could also be used as dissolvant, plasticizer and lubricant for the analytical reagent and stationary liquid, cellulose and esters.

When comes to its making method, it could be made from esterification of phthalic anhydride and alcohol. The specific way is below: prepare the phthalic anhydride and alcohol, and go through the reflux reaction with the existence of sulfuric acid(catalytic agent), and then get the crude products.  finally, have the distillation to get the ultimate products. As to its product categories, there are various, including phthalates; organics; analytical chemistry; environmental endocrine disruptors; functional materials; phthalates (environmental endocrine disruptors); phthalates (plasticizer); plasticizer.

Additionally, you could convert the following data information into the molecular structure:
SMILES:O=C(OCC)c1ccccc1C(=O)OCC
