[0002] Environmentally friendly plasticizers are hygienic, low-toxic plastic additives. Environmentally friendly plasticizers are widely used in plastic toys, medical devices, food packaging, flooring, wall veneer, building materials, automobile manufacturing and packaging materials. For example, bio-based plasticizers are suitable for plastic products such as PVC and PE, and low-toxic plasticizers are suitable for high-demand fields such as toys, food packaging and medical equipment. Environmentally friendly plasticizers are designed to improve the softness and ductility of plastic products while reducing negative impacts on the environment and human health. Compared with traditional plasticizers, environmentally friendly plasticizers pay more attention to environmental protection and health. They are usually made of bio-based materials, or have low toxicity and biodegradability, so they have less impact on the environment. Esterification reaction devices can be used to react environmentally friendly plasticizers. Plasticizers are the world's largest production and consumption. Plastic Additives One of them. my country has become the country with the largest production and consumption of plasticizers in Asia. With the improvement of environmental awareness in countries around the world, plastic products such as medicine and food packaging, daily necessities, and toys have put forward higher purity and hygiene requirements for the main plasticizer DOP. However, the main plasticizers produced by domestic enterprises are difficult to meet environmental protection requirements in many properties, especially hygiene and low toxicity. The EU and Russia have successively found that some plastic toys imported from China contain toxic polyvinyl chloride plasticizers N-diisononyl phthalate (DINP) and diethylhexyl phthalate (DEHP, or DOP). The environmentally friendly plasticizer can be processed by using a reactor. During the operation, there will be residual liquid adhering to the reactor, and the residual liquid can be recovered by using a recovery device.
