| Use | mainly used as PVC plasticizer, widely used in plastics, rubber, paint and lubricating oil, emulsifiers can be used as plasticizers for cellulose resin, vinyl resin, nitrile rubber and chlorinated rubber in industry. The plasticizing efficiency is similar to DBP, but the volatility and water pumping are larger than DBP, which can be used as a substitute for DBP. This product is toxic to crops and is not suitable for agricultural polyvinyl chloride film. The low toxicity, rats oral LD50 20-25g/kg. The United Kingdom, the Netherlands, the United States allowed the use of the product in food packaging materials, the United Kingdom in polyvinyl chloride and vinyl chloride copolymer of food packaging products, the maximum amount of the product should not exceed 40%. DIBP is one of the commonly used primary plasticizers. It can be used as a plasticizer for cellulose resin, vinyl resin, butadiene rubber, chlorinated rubber and the like. The plasticizing effect is similar to DBP, and has excellent solubility, dispersibility and adhesion. This product has good compatibility with pigments, and can be used for coloring films, artificial leather and plastic products. This product can also be used as a softener for natural rubber and synthetic rubber, which can improve the resilience of products. Can be used as an alternative to DBP. |
| production method | is obtained by esterification of phthalic anhydride with isobutanol. The esterification reaction is carried out under the catalysis of sulfuric acid, and the proportion is 1:1.35-1.4, and the liquid phase esterification is carried out for 5-6h under normal pressure. |
