Clean synthesis of epoxy plasticizer with quaternary ...

Abstract The toxic petroleum-based phthalates account 80% of the total plasticizer consumption in China. Conventional methods for preparing epoxy plasticizers produces a large amount of waste water. Furthermore, cardanol (a byproduct of cashew nut processing) has the potential to be an economic alternative for producing fine chemical products.

Abstract Cardanol is a substituted phenol obtained from cashew nut shell liquid (CNSL) by the vacuum distillation. It is a feasible alternative to petrochemically derived phenol for many applications. Cardanol has shown potential as a suitable sustainable linker to chemically bind polymers used as internal plasticizers. This research project explores the utilization of cardanol in grafting of ...

A series of new environment-friendly plasticizers was synthesized from castor oil and used to plasticize nitrile rubber (NBR). The test results showed that tensile strength, elongation at break, and tear strength of NBR vulcanizates plasticized by castor oil-based plasticizers were found to be better than that of dioctyl phthalate (DOP). The aging test taken demonstrated that the castor oil ...
