Synthesis and properties of castor oil based plasticizers
Two types of epoxy acetyl castor oil polyol ester plasticizers were synthesized by Jia et al. and had better plasticizing effect than DOP and ESO, 16 but the tensile strength of the PVC blends was much lower than that from ESO, which makes its replacing of soybean oil impractical.
Synthesis and Characterization Plasticizer Epoxy Acetyl
Synthesis and Characterization Plasticizer Epoxy Acetyl Polyglycerol Ester Feng Guodong, H. Yun, +1 author Zhou Yonghong Published 2014 Chemistry o Abstract- With crude glycerine coming from the by-product of biological diesel oil as raw material , polyglycerol was prepared by polymerization.
Synthesis and Characterization of New PGN Based Reactive
The terminal hydroxyl group of plasticizer capped with methoxy and acetyl groups to generate two other types of reactive plasticizer. The chemical structure of plasticizers has characterized by FT‐IR and 1 H NMR spectroscopy as well as DSC, and TGA methods. Also, plasticizers reactivity toward alkyne‐azide reaction, have evaluated through
Synthesis and application of eleostearic acid based plasticizer
Abstract. This study reports the synthesis of a kind of biomass-based plasticizer: epoxy eleostearic acid catechol ester (EEAE), originating from biomass resources eleostearic acid and catechol by way of esterification and epoxidation. Its effect on the plasticization, mechanical properties and migration resistance of poly (vinyl chloride) (PVC
Synthesis of Biomass Based Plasticizer from Linoleic Acid and
In this paper, we synthesized a kind of bio-based plasticizer epoxidized linoleic acid cardanol ester (ELCE) from cardanol and linoleic acid. Its chemical structure was characterized with FT-IR and 1H NMR. Polyvinyl chloride (PVC) blends plasticized with ELCE were prepared via thermoplastic blending with torque rheometer. The performance including torque, mechanical property, thermal stability
- 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.
- Does epoxy acetylated castor oil increase tensile strength?
- Specifically, the tensile strength and elongation at break of a PVC sample plastified by epoxy acetylated castor oil (EACO) were 18.5 and 10.0% higher than that of DOTP, and 13.9 and 23.8% higher than that of ESO, respectively.
- What is epoxidized methyl acetoricinoleate?
- For example, epoxidized methyl acetoricinoleate is a common castor oil based plasticizer with high epoxy value and good thermal stability, 15 but a large amount of glycerol is produced during its preparation, which represents excess capacity.
- 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.
- What are the plasticizing effects of synthesized plasticizers in PVC?
- The plasticizing effects of the synthesized plasticizers in PVC as plastisol viscosities, thermal stability, glass transition, tensile properties, hardness, migration stability, exudation loss, and volatility stability were measured and compared to DOP.
- How to make bio-compactible plasticizer?
- One of the most distinguished methods in producing bio-compactible plasticizer is the epoxidation of vegetable oils and fatty acid. There are several processes for the epoxidation such as chemical and chemoenzymatic processes.
