| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| use | this product is compatible with cellulose acetate, nitrocellulose, ethyl cellulose, vinyl resin, polyvinyl butyral, alkyd resin, etc. It is mainly used as a plasticizer for cellulose acetate. Its volatility is smaller than diethyl phthalate, which can have good durability and make the film tough. It can be used for enameled wire, film film, high-strength varnish, adhesive and laminate adhesive, etc. It is also used as a sensitizer and solvent for gas chromatography fixing liquid and triacetic acid sheet base. Used as a plasticizer for cellulose acetate |
| Production method | The addition reaction of ethylene oxide with methanol and boron trifluoride ether is carried out to neutralize the reaction product to obtain methoxyethanol. It is then esterified with phthalic anhydride, and then decolorized with activated carbon, distillation, water washing, alkali washing, dehydration, and pressure filtration to obtain the finished product. After the esterification reaction product is washed with water, it is distilled under reduced pressure. This post-treatment process is also used in industrial production. The content of industrial DMEP is ≥ 99. Raw material consumption quota: phthalic anhydride 750kg/t, ethylene oxide 820kg/t, methanol 660kg/t. |
