Synthesis of castor oil based plasticizers containing flame
Epoxidized castor oil (ECO) and castor oil phosphate ester (COPE) were synthesized. Structure of two functionalized castor oil was characterized with FTIR and 1H NMR. Property of poly...
Synthesis and properties of castor oil based plasticizers
Besides, a series of phosphorus-containing flame retardant plasticizers based on castor oil as a secondary plasticizer were synthesized and the results showed that the material added plasticizers had improved tensile strength, with good heat insulation and flame retardant properties, but the elongation at break was decreased. 18–21
Synthesis and properties of castor oil based plasticizers
Synthesis of acetylated castor oil (ACO) Castor oil (93.4 g) and acetic anhydride (27.5 g) were added to a 500 mL four-necked flask, and were stirred at 140 °C for 2 h. Then the reaction mixture was washed to pH = 7 with sodium carbonate solution and distilled water. Then the water was removed by vacuum distillation.
Synthesis and Application of Environmental Castor Oil Based
Design and synthesis of a castor oil based plasticizer containing THEIC and diethyl phosphate groups for the preparation of flame-retardant PVC materials. RSC Advances 2017, 7 (2) , 897-903. DOI: 10.1039/C6RA25014A. Puyou Jia, Rui Wang, Lihong Hu, Meng Zhang, Yonghong Zhou.
A composition of phosphaphenanthrene groups-containing castor
Phosphorus-containing castor oil based plasticizer (PPC) was synthesized from castor oil, formic acid, phosphate, hydrogen peroxide (H 2 O 2) and diethyl phosphate [19]. It can be used as secondary plasticizer to enhance the flame retardant property of 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.
- What is a plasticizer made from castor oil?
- A series of environment-friendly plasticizers has been synthesized from castor oil through a mild esterification/epoxidation reaction. Poly (vinyl chloride) (PVC) is currently one of the largest produced synthetic resin products in the world.
- Is castor oil based diglycidyl ester plasticizer good for PVC?
- A castor oil-based diglycidyl ester plasticizer (C26-DGE) was prepared by Chen et al. 17 with ricinoleic acid as raw material and results showed that the plasticizer endowed the PVC matrix with enhanced compatibility and flexibility.
- Can castor oil plastify PVC?
- Sci. 2018;135:46270. doi: 10.1002/app.46270. [DOI] [Google Scholar] A series of environment-friendly plasticizers has been synthesized from castor oil through a mild esterification/epoxidation reaction. The modified epoxy acetylated castor oil (EACO) can plastify poly (vinyl chloride) (PVC) efficiently, even better ...
- What is castor oil chemistry?
- Castor oil molecules contain hydroxy groups, carbon–carbon double bonds and ester bonds, which can be undergo epoxidation, sulfonation, halogenation, esterification, hydrolysis and other reactions to produce different varieties of plasticizers.
- Can castor oil plastify and epoxidize soybean oil?
- A series of environment-friendly plasticizers has been synthesized from castor oil through a mild esterification/epoxidation reaction. The modied epoxy acetylated castor oil (EACO) can plastify (DOTP) and epoxidized soybean oil (ESO), in terms of in tensile strength, migration stability, solvent extraction stability and thermal stability.
