Synthesis and properties of castor oil based plasticizers
In this study, five types of environment-friendly material plasticizers based on castor oil were synthesized. The synthetic plasticizers were added to PVC as the main plasticizer, and the properties of these PVC blends were investigated and compared to the commercial plasticizers DOTP and ESO.
Design and synthesis of a castor oil based plasticizer
2.2.3 Synthesis of castor oil based flame retardant plasticizer containing THEIC and diethyl phosphate groups (THEIC–MR phosphate) THEIC–MR and diethyl chlorophosphate in a molar ratio of 1 : 3 were dissolved in 100 mL of chloroform. The mixture was placed in a 250 mL flask and stirred at 60 °C for 3 h to finish the reaction.
Synthesis and Application of Environmental Castor Oil Based
PVC materials were prepared via blending the synthesized castor oil based polyol esters as the main plasticizer. Properties of the PVC materials were investigated and compared to those of commercial plasticizers (DOP and ESO). The results showed that castor oil based polyol esters could significantly improve thermal stability of PVC blends.

Design and synthesis of a castor oil based plasticizer
A fine chemical product based on a castor oil containing THEIC and diethyl phosphate groups (THEIC-MR-phosphate) was designed and synthesized, and it was used as a substitute flame retardant plasticizer to prepare PVC materials instead of the commercial plasticizer dioctyl phthalate (DOP).
- Can castor oil be used as a flame retardant plasticizer?
- In this study, we designed and synthesized a novel fine chemical product based on castor oil containing THEIC and diethyl phosphate groups. The product was used as a flame retardant plasticizer for preparing flame PVC materials.
- Is castor oil a sustainable plasticizer?
- The design strategy based on castor oil highlights a sustainable avenue for preparing cost-effective and high-efficiency plasticizers. A series of environment-friendly plasticizers has been synthesized from castor oil through a mild esterification/epoxidation reaction.
- Does epoxy acetylated castor oil increase tensile strength?
- Specifically, the tensile strength and elongation at break of a PVC sample plastified by epoxy acetylated castor oil (EACO) were 18.5 and 10.0% higher than that of DOTP, and 13.9 and 23.8% higher than that of ESO, respectively.
- Which plasticizer reduces Tg of PVC materials?
- DSC and tensile tests indicated that the compound plasticizer (DOP and THEIC–MR-phosphate) reduced the Tg of the PVC materials; the plasticizing effect of DOP was lower than that of the THEIC–MR-phosphate, but it can still be used as the main plasticizer in rigid PVC materials with high flame retardant requirements.
