| Introduction | dicyclohexyl phthalate (DCHP) is a special plasticizer with moisture resistance. A large number of studies have proved that its toxicity is very low, at present, the domestic production capacity is relatively low, the vast majority rely on imports, mainly through the esterification of industrial production. |
| Use | used for polyvinyl chloride, acrylic resin, polystyrene, main plasticizer for nitrocellulose and the like This product is a phthalate-based plasticizer. This kind of plasticizer variety, large output, accounting for about 80% of the total output of plasticizer, has a more comprehensive performance, generally used as the main plasticizer. Among the phthalate esters, dioctyl phthalate (DOP) is the most widely used, accounting for about 45% of the total plasticizer in China. Dicyclohexyl phthalate can be used as the main plasticizer of polyvinyl chloride, acrylic resin, polystyrene, nitrocellulose and other resins, with moisture-proof effect, and other plasticizers, can make the product shrink dense, prevent water vapor transmission and plasticizer volatilization. The surface of the plastic product containing the product is smooth and feel good. The amount of the product is generally accounted for 10-20% of the total amount of plasticizer, the amount should not be too large, otherwise the hardness of the product increases. The product can improve the fluidity of the resin during thermal processing. In the synthetic resin adhesive, the product can improve the adhesion, oil resistance and durability. In addition, the product is also used for nitrocellulose and some natural resins, can be made moisture coating. The toxicity of the product is low, with the product containing 25% of the olive oil agent on rats directly after oral exposure, 24H no death cases, in 7d LD50 30ml/kg. The product was mixed into the feed at a dose of 10 mg/kg, and the rats were fed for four generations for 8 months. The growth, reproduction and lactation of the experimental animals showed no abnormality and no carcinogenicity. used as raw material, toughening agent and plasticizer of high molecular polymer |
| production method | is obtained by esterification of phthalic anhydride and cyclohexanol. Raw material consumption (kg/t) phthalic anhydride 500 cyclohexanol 670 cyclohexanol was added to the reaction kettle, Catalyst sulfuric acid (0.5%) was added with stirring, and phthalic anhydride was added to dissolve. The temperature rise was continued and the by-products were continuously removed under reduced pressure. Reflux under reduced pressure for 4 h. Neutralization, decompression distilled water and cyclohexanol product. |
