Synthesis and Properties of Isosorbide-Based Eco-friendly
In this study, isosorbide-based eco-friendly and effective plasticizers were synthesized and characterized. Isosorbide esterification was conducted using fatty acids with different alkyl-chain lengths; the optimal degree of isosorbide esterification was obtained after 6 h reaction at 220 °C with a short alkyl-chain fatty acid in the presence of the catalyst Ti(OBu)4. Isosorbide-based
Developments of biobased plasticizers for compostable
The development and utilization of biobased plasticizers derived from epoxidized soybean oil, castor oil, cardanol, citrate, and isosorbide have been broadly investigated. The synthesis of...
“Green” films from renewable resources: Properties
Epoxidized soybean oil (ESO), a vegetable oil, is used extensively as lubricant, reinforcing agent, plasticizer, etc., in composites because of the inherent advantages of huge quantities, low...
"Green" films from renewable resources: properties
Results showed that ESO was an effective plasticizer that outstripped conventional plasticizers, i.e. dibutyl phthalate (DBP) and triethyl citrate (TEC) in producing high-quality films. Especially, at plasticizer concentrations of 15-25%, ESO-EC films had preferable mechanical properties and better thermal stability, as well as non-flammability.
Epoxydized Soybean Oil - ESBO Plasticizers | Payal Group
Bio-degradable, renewable and eco-friendly Phthalate-free and non-toxic Good compatibility with a variety of surface coating materials like PVC, PVA, nitro cellulose, chlorinated rubber etc. Excellent heat and light stabilization Resist migration, less volatility and not easy to extract.
- Why are plasticizers based on ESO so popular?
- Due to theworldwide availability and relatively low prices of soybean oil, chemical plants that produce ESO are spring up all over the world. Meanwhile, novel plasticizers based on ESO have been developed in the past several years .
- How is epoxidation of ESO made?
- Moreover, ester bonds in the ester plasticizers improved the plasticizing efficiency . In the epoxidation process, ESO is synthesized byreacting soybean oil with peracids generated in situ. Generally, sulfuric acid is added into the reaction mixture to accelerate the peroxidation reaction .
- Why are plasticizers added to PVC?
- General, plasticizers are added into PVCto improve the thermal, mechanical and flame-retardant properties . Nowadays, there are more than 500 kinds of plasticizers in the market. Among them, phthalate plasticizers dominate the main commercial plasticizers . These phthalate plasticizers are derived from petroleum resources.
