Okian DOP oil with the chemical name of dimethyl phthalate and the chemical formula C24H38O is a clear, oily, colorless, odorless, water-soluble, non-toxic, flammable liquid with solubility in organic solvents, alcohol and hexane, resistant to abrasion And corrosion, with a melting point of -50 degrees and a very high boiling point (385 degrees Celsius), which is one of the most important emollients of PVC granular powder.
Okian DOP oil production method
It is usually produced by sterilization of 2-ethyl hexanol and anhydride phthalate in the vicinity of sulfonylureas (as a reaction accelerator, ie catalyst) in a discontinuous reactor and in batches for approximately 12 hours (approximate production time of each batch). . In fact, these materials are combined in a reactor equipped with a mixer at high temperatures, then the oil is passed through a strainer and then the temperature is reduced and the final oil is obtained.
Application of Okian DOP oil
This material has many applications in various industries, for example, as a solvent in adhesive industries, in the manufacture of sealants (as a softener and for the formability of PVCs, which are the main building materials of sealants), in the production of balls (as Complementary and emollient for PVCs, which are the most important material in making balls, in the construction of granule hoses (granules are solid, so this oil is used to increase the formability in the process of melting granules). , In the production of cables (PVC powder combined with this oil and used as a coating around wires), in the production of synthetic leather (this oil causes the formation and softening of synthetic leathers, which are often made of polymeric materials) Have been used in the production of toys, air filters, etc.
