Epoxidized vegetable oil and bio‐based materials as PVC
Bondeson studied the epoxidation of vegetable oils such as soybean, sunflower, and safflower are good replacements for DINP in PVC materials used for indoor applications. 95 Moreover, the rate of crosslinking is positively correlated with the degree of epoxidation of the epoxidized vegetable oils.
Research progress of novel bio-based plasticizers and their
Biomass renewable resources have wide range of sources and low prices, and the chemicals obtained from them have various structures, which can provide a huge platform to design novel PVC plasticizers with the aim of replacing traditional phthalate plasticizers. Many bio-based PVC plasticizers, such as vegetable oil-based plasticizers, cardanol
- Is epoxidized soybean oil a good plasticizer?
- Indeed, it is an interesting route due to it being greener and safer. 68–70 Epoxidized soybean oil (ESO) occupies about 4.9% of the total plasticizer market. 71 After epoxidation, some extent of double bonds remains unchanged, which increases the molar mass of the product and consequently, reduces the compatibility with PVC.
- Why are epoxidized triglyceride oils used as secondary plasticizers?
- These are the reasons why epoxidized triglyceride oils are mostly utilized as secondary plasticizers. 72–74 Epoxy groups catch the HCl released from the thermal degradation of PVC, give exceptional light, and heat stability to PVC. 75 Until now, every catalytic system has been associated with both benefits and bottlenecks.
- Can vegetable oils replace phthalate plasticizers?
- Functionalization of vegetable oils (VOs) including edible, non-edible, and waste cooking oil (WCOs) to epoxides (EVOs) is receiving great attention by many researchers from academia and industry because they are renewable, versatile, sustainable, non-toxic, and eco-friendly, and they can partially or totally replace harmful phthalate plasticizers.
- What is epoxidation of vegetable oil?
- Epoxidation is the chemical reaction that converts the carbon–carbon double bond into oxiranes (epoxides) using a variety of oxidizing agents. Various methods have been developed for the epoxidation of vegetable oils as follows: • Homogeneous catalytic system by peroxyacids. • Heterogeneous catalytic system by acidic ion exchange resins (AIERs).
- Can vegetable oils be used as epoxides?
- However, May et al.109 and Meyer et al.113 approved that vegetable oils with a rather high content of unsaturation or high iodine value such as soybean and linseed oils can be selected as a prior raw material to produce epoxides with high epoxy functionality. 3. Epoxidation of vegetable oils
- What is enzymatic epoxidation of sunflower oil?
- With the purpose of using easily removable free fatty acid and to get the final product with a low acid value (AV), the enzymatic epoxidation of sunflower oil was conducted in the presence of Novozym 435 and short-chained butyric acid as an active oxygen carrier.
