Benzyl Octyl Phthalate Liquid Usage and Synthesis:

Benzyl octyl phthalate is a chemical reagent, a transparent oily liquid. Relative density 1.070, freezing point -45℃, boiling point 252℃. It is a kind of main plasticizer with special performance. It has similar properties with low molecular weight polyester plasticizers, good anti-pollution, low volatility and migration resistance, and maintains the good processing properties of monomeric plasticizers. Good processing performance. The products are tear-resistant, wear-resistant, high strength, and heat-resistant, light-resistant, and good low-temperature flexibility.

Pharmacokinetics of Benzyl Octyl Phthalate:

A four-necked flask was placed in an oil bath and fitted with a stirrer, thermometer and reflux condenser. Phthalic anhydride, n-octanol and sulfuric acid were added to the flask. Slowly increase the temperature under constant stirring to 138 ~ 140 ℃, so that all the phthalic anhydride melt into a transparent liquid. And then raise the temperature to 100 ~ 110 ℃, the reaction for 2 hours. Monooctyl phthalate is produced. The generated reactants Lower the temperature to 60 ~ 80 ℃, under constant stirring drop into the sodium hydroxide solution, about 30 minutes to add, and then adjust the pH of the reaction products with sodium carbonate solution of the resulting crude ester with water Steam distillation to remove the low boiling point substances, and then distillation under reduced pressure to remove water, and finally produced a light yellow transparent oily liquid, that is, the finished product.

Clinical Application of Benzyl Octyl Phthalate:

Benzyl Octyl Phthalate is made from phthalic anhydride, n-octanol and benzyl chloride by condensation reaction. It can be used as plasticizer for PVC resin and acrylic resin coating, especially for PVC film, sheet, artificial leather, plasticizer paste, foam and other products. It is especially suitable for PVC film, sheet, artificial leather, plasticizer paste, foam and other synthetic rubber resins. This product can be used as plasticizer for PVC resin and acrylic resin coating. It has It has similar properties to low molecular weight polyester plasticizers and maintains the good processing properties of monomeric plasticizers. leather, plasticizer paste, foam, and polyacrylate paints.
