1.Dioctyl phthalate is a general-purpose plasticizer mainly used for the processing of PVC resins, as well as for the processing of high molecular materials such as chemical resins, acetic acid resins, ABS resins, and rubber, as well as for paints, dyes, dispersants, and so on. Dioctyl phthalate plasticized PVC can be used in the manufacture of artificial leather, agricultural films, packaging materials, cables, and so on.
2. Dioctyl phthalate can be used as an organic solvent and gas chromatographic stationary liquid.
3.It is the most widely used plasticizer in industry. Except for cellulose acetate and polyvinyl acetate, this product has good compatibility with most synthetic resins and rubbers used in industry. This product has good comprehensive performance, good mixing performance, high plasticizing efficiency, low volatility, good low-temperature flexibility, good water immersion resistance, high electrical performance, good heat resistance, and good weather resistance.
4. In HVAC, it is used to test the filtration efficiency of high-efficiency filters. Since 0.3 microns is the particle diameter with the highest penetration rate of the high-efficiency filter, dioctyl phthalate was used to test the filtration efficiency of the high-efficiency filter.
Dioctyl phthalate is a colorless or yellowish transparent liquid with a special odor, boiling point of 386 ℃, and relative density of 0.980~0.983 (20/4 ℃). Insoluble in water, soluble in ethanol, ether, and other organic solvents. It is prepared by esterification of phthalic anhydride and 2-ethylhexanol. It is one of the most widely used plasticizers in plastic processing. Good overall performance, high growth efficiency, low volatility, UV resistance and cold resistance, improving the softness and electrical property of the product. It is an ideal main plasticizer. Less toxic, with a half lethal dose greater than 30 g/kg body weight. The French Cancer Institute has fed 0.05% of its feed to four generations of rats, which proves that it is non-toxic and carcinogenic. However, the carcinogenic effect of large doses remains to be further studied. The United Kingdom, France, Japan, the Netherlands, Germany, and other countries allow it to be used in plastic products in contact with food (except for high-fat foods), and the United States Food and Drug Administration allows it to be used as cellophane, paint, adhesives, and rubber products for food packaging. It can also be used as a standard sample for chromatographic quantitative analysis.
