Professional R&D and excellent quality plasticizer chemicals

Currently, the production of non-toxic, eco-friendly, biodegradable plasticizers in China is facing two critical challenges: (1) low yields with numerous side reactions; (2) low production volume and high cost. The costs of these plasticizers such as citrates are rather high due to the use of expensive catalysts, forcing the users to choose low

On the other hand, high temperature also promoted side reaction, such as ring-opening reaction. In the optimization. Conclusion. Four novel plasticizers based on ESO were prepared through integration of epoxidation catalyzed by α-Al 2 O 3 ·H 2 O and ring-opening reaction with H 2 SO 4 as a catalyst. Modified micro-flow system consisting of

As most plasticizers are obtained by esterification from acids and acid anhydrides, this is a criterion to establish the purity of the product. It must be less than 0.08 mg KOH g 1. Boiling point (ASTM D86). It is considered for the safety of the process. Normally it must be higher than 205 °C. Color APHA (ASTM D1209, ASTM 1045, ASTM D1544).

Plasticizers are essential to make PVC flexible. PVC is naturally rigid, but plasticizers are added to make the tubing flexible and expandable while retaining its shape. DEHP is widely used because it is low cost, processes well, and has provided good end-use performance.

Thus, the developed methods allow for the successful quantitative recovery of high-purity Cu, PVC, and DINP without requiring any of the complex multistep physical separation processes involved in the conventional granulation technique for the recycling of waste wire harnesses.
