Synthesis and properties of castor oil based plasticizers
Plasticizers prepared from vegetable oils mainly include epoxy vegetable oils, 5–8 and epoxidized fatty acid esters. 9 In these types of plasticizers, the presence of the epoxy group makes the plasticizers have a better plasticizing effect on PVC and plays a role as stabilizer. 10 When heated, PVC undergoes autocatalytic dehydrochlorination,
Plasticizers: Types, Uses, Classification, Selection & Regulation
Still the world’s most widely used PVC plasticizer DINP, DIDP: High molecular weight ortho-phthalates Aliphatic dibasic acid Esters – These include chemicals such as glutarates, adipates, azelates and sebacates. They are made from aliphatic dibasic acids such as adipic acid and alcohols.
Research progress of novel bio-based plasticizers and their
2,5-Dicarboxylic acid ester is derived from biomass resources, but has a structure similar to terephthalic acid ester. As a green chemical, it has the potential to replace petroleum-based plasticizers. Nguyen et al. used raw materials derived from marine biomass to synthesize furan-2,5- and furan-2,3-dicarboxylate as plasticizers for PVC. The
What are the main types of plasticizers? - WSD Chemical
At present, phthalates esters is 80-85% of the total plasticizers. The main products: DOP, DIOP, DIDP, DINP, DBP, DIBP, DOTP. 2. Fatty acid esters have good cryogenic properties, but they are poorly soluble with polyvinyl chloride, so they can only be used as cold-resistant plasticizers and co-phthalates.
- Can epoxidized fatty acid Isobutyl esters be used as biobased plasticizer in PVC?
- However, few studies on the preparation and application of epoxidized fatty acid isobutyl esters (Ep-FABEs) as the biobased plasticizer in PVC were reported. In this paper, a two-step approach, including transesterification and epoxidation, was adopted to prepare Ep-FABEs using biodiesel as the raw material, as shown in Fig. 1.
- Does epoxidized fatty acid tri-esters bio-plasticizer reduce efame?
- Governed by the interplay between two extra polar, PVC-compatible short esters and higher molecular weight relative to ordinary EFAME, the fogging value of the resulting epoxidized fatty acid tri-esters bio-plasticizer was found to reduce to a level comparable to DIDP.
- What are bio-based alternatives to epoxidized fatty acid methyl ester?
- In this scenario, the last decade has witnessed an emergence of multiple bio-based alternatives, including epoxidized fatty acid methyl ester (EFAME), epoxidized soybean oil (ESO) and acetyl tributyl citrate (ATBC), as well as a surge of their application in PVC artificial leather industry.
- What are biobased plasticizers?
- To date, biobased plasticizers mainly include epoxidized fatty acid methyl esters (Ep-FAMEs) , aliphatic diesters , epoxidized triglycerides , and citrate plasticizers .
- What is efame & epoxidized fatty acid methyl esters?
- In general, commercial EFAME is a mixture mainly containing epoxidized fatty acid methyl esters, and a proportion of saturated fatty acid methyl esters, depending on the source of the feedstock .
- Can Fames be converted to epoxy plasticizer?
- Conclusion Conversion of FAMEs to epoxy plasticizer could achieve a co-production of biodiesel and bio-plasticizer. The epoxidation of FAMEs is usually performed in an oil-water bio-phase system with in situ formed peracid as an oxygen carrier.
