| use | diisopropyl phthalate is a reactive plasticizer, mainly used to prepare diisopropyl phthalate resin, used as a crosslinking agent for unsaturated polyester resin, and a reinforcing agent for cellulose resin. And used as a plasticizer for resins that can polymerize themselves without inhibitors. It is used to make polyphthalate dipropylene ester resin, crosslinking agent for unsaturated polyester resin, plasticizer for vinyl resin, catalyst for polyester resin and pigment carrier, etc. At the same time, it can be used as many polymer and copolymer monomers. This product is a reactive plasticizer, mainly used to prepare diisopropyl phthalate resin, used as a crosslinking agent for unsaturated polyester resin, and a reinforcing agent for cellulose resin. And used as a plasticizer for resins that can polymerize themselves without inhibitors. used to prepare DAP polymerization solution and DAP resin, also used as cross-linking agent used as plasticizer dipropylene phthalate is a reactive plasticizer, mainly used to prepare diisopropyl phthalate resin, as a cross-linking agent of unsaturated polyester resin, and as a reinforcing agent of cellulose resin.

| preparation method | phthalic anhydride reacts with liquid alkali to generate sodium phthalate, which is then esterified with chloropropene at 40-60 ℃ under normal pressure to obtain crude product. After filtration, neutralization; water washing; reduced pressure distillation, that is, the finished product. It can also be manufactured by direct esterification: 1) esterification reaction; The metered amount of phthalic anhydride 119kg, allyl alcohol (adding 1% hydroquinone) 121kg and benzene 156kg are added into the esterification kettle, and the metered amount of sulfuric acid (65%) is gradually added. Start heating to 80~95 ℃. The water generated in the reaction process is evaporated with benzene in the same boiling, the condensate is separated by a benzene water separator to remove the water, and the benzene flows back to the reaction kettle until the hourly water output is less than 100ml to finish the reaction and cool down.

Repeated water washing and neutralization until the pH value of the water layer is neutral. China plastic online plastic encyclopedia http://baike.21cp.com 3) distillation and debenzene: wash and neutralize the good materials and put them into a debenzene distillation kettle, heat them with steam, and evaporate benzene to obtain crude diallyl phthalate monomer (DAP). 4) vacuum distillation: crude DAP monomer is rectified in an intermittent distillation kettle at a temperature of about 180 ℃ and a pressure of 266~532Pa(2~4mmHg), and the fraction at 180~200 ℃ is collected as refined DAP monomer. |
| production method | phthalic anhydride reacts with liquid alkali to generate sodium phthalate, which is then esterified with chloropropene at 40-60 ℃ under normal pressure to obtain crude product.
