EPOXOL 7-4 Epoxidized Soybean Oil | ACS Technical Products
Plasticizer / Acid Scavenger. EPOXOL 7-4 is a bio-based high oxirane epoxidized soybean oil (ESO). Our unique manufacturing process produces an exceptional ESO especially suited for general purpose PVC formulations, acid scavenging and as a chemical intermediate with multiple reactive sites. EPOXOL 7-4’s oxirane makes it especially
Design and Synthesis of Epoxidized Soybean Oil‐Branched Cardanol Ethers
The chemical structure of ESO-CDn is fully characterized. Furthermore, the thermal, mechanical, rheology, and migration resistance properties of PVC/ESO/CD and PVC/ESO-CDn are compared. The relationship between the molecular structure and plasticizer performance is investigated, and the plasticization mechanism is proposed.

ChemFlexx Epoxidized Soybean Oil (ESO) - The Chemical Company
TCC’s epoxidized soybean oil (ESO) is used as a plasticizer and stabilizer in plastic materials, especially PVC and its copolymers to keep these plastics soft and pliable. The chemical is also used as a pigment dispersing agent and acid/mercaptan scavenging agent as well as an epoxy reactive diluent.
Epoxidized Soybean Oil (ESO) - Chemical Supplier Distributor
Application. Epoxidized Soybean Oil (ESO) is produced through the oxidation of high iodine value unsaturated soybean oil with hydrogen peroxide and organic acids such as acetic acid or formic acid. ESO is primarily used as a co-plasticizer for flexible polyvinyl chloride (PVC) and its copolymers. It also acts as a secondary heat and light
- Is ESO a non-toxic plasticizer?
- Among them, ESO, one of green non-toxic plasticizers recognized by FDA, has received much attention during the past several decades . Due to the worldwide availability and relatively low prices of soybean oil, chemical plants that produce ESO are spring up all over the world.
- How is epoxidation of ESO made?
- Moreover, ester bonds in the ester plasticizers improved the plasticizing efficiency . In the epoxidation process, ESO is synthesized by reacting soybean oil with peracids generated in situ. Generally, sulfuric acid is added into the reaction mixture to accelerate the peroxidation reaction .
- Why are plasticizers based on ESO so popular?
- Due to the worldwide 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 are novel plasticizers based on ESO prepared?
- 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 two micro-mixers and fixed bed flow reactors was applied in the epoxidation process, yielding ESO with an oxirane value of 6.1.
- Is acylated polyols-methanol a better plasticizer than ESO?
- Thus, the content of ester groups in the structure of plasticizers should be controlled in reasonable range despite the advantage in compatibility with PVC polymer. Under comprehensive consideration, acylated polyols-methanol displayed relatively superior plasticizer compared with ESO. 4. Conclusion
- Do explosive reagents participate in the epoxidation process of soybean oil?
- In our previous study, the participation of explosive reagents in the epoxidation process of soybean oil was conducted in the micro-flow system. Higher oxirane value was obtained in the continuous synthesis of ESO , .
