Synthesis of a bio-based plasticizer from oleic acid and its
Moreover, an oleic acid-based plasticizer was described by Omrani et al. [88] It was obtained using reactions with thioglycolic acid and then with hydrogen peroxide to get sulfone group....
Synthesis of a bio-based plasticizer from oleic acid and its
The bio-based plasticizers have been extensively developed due to their high compatibility and low toxicity. In this study, the bio-based plasticizers of methyl 10-(2-methoxy-2-oxoethansulfonyl) octadecanoate (MDA) and ethyl 10-(2-ethoxy-2-oxoethanesulfonyl) octadecanoate (EDA) were synthesized from the oleic acid and thioglycolic acid and characterized by 1 HNMR and FT-IR.
Synthesis and evaluation of epoxidized vegetable oleic acid
A bio-based plasticizers, acetyl-oleate triethylene glycol (AOT), was successfully synthesized by using oleic acid as a raw material through esterification, epoxidation, and acetylation. Its structure was analyzed by Fourier transform infrared spectroscopy and 1 H nuclear magnetic resonance.
Synthesis and properties of a bio-based PVC plasticizer
A novel green plasticizer, acetylated lactic acid 1,6-hexane diester (ALHD), was successfully synthesized based on l-lactic acid, a renewable organic acid from corn starch. Its chemical structure was characterized using FTIR, 1H NMR and matrix-assisted laser desorption/ionization time of flight mass spectrom
Research progress of novel bio-based plasticizers and their
The synthesis route of epoxidized castor oil-based ester is shown in Scheme 1. They added these prepared plasticizers to PVC as the main plasticizer and compared their plasticizing properties with epoxidized soybean oil (ESO) and dioctyl terephthalate (DOTP).
- Are oleic acid-based hyperbranched plasticizers brittle?
- However, its intrinsic brittleness restricts its widespread application. In this study, we leveraged the potential of resources to successfully design and synthesize a variety of oleic acid-based hyperbranched plasticizers by combining them with the green platform chemical alcohol ether ester.
- Are oleic acid-based hyperbranched polylactic acid biodegradable?
- Polylactic acid (PLA) has garnered significant attention as a biodegradable and renewable material. However, its intrinsic brittleness restricts its widespread application. In this study, we leveraged the potential of resources to successfully design and synthesize a variety of oleic acid-based hyperbranched
- What are the mechanical properties of Bio-Base plasticizers?
- The structures of bio-base plasticizers (a, b and c) were confirmed by Fourier transform infrared spectroscopy (FT-IR), 1 H NMR and 13 C NMR. The mechanical properties of a/PVC were as good as those of PVC films with the dioctyl phthalate (DOP) plasticizer. Meanwhile, the elongation at break of c/PVC reached 422%.
- Which Bio-Base plasticizer has a better plasticizing effect at low temperature?
- The FT-IR of PVC films showed that the downfield shifts of the —CH—Cl groups of the PVC plasticized with a and c were greater than that of b/PVC. The bio-base plasticizers b had a better plasticizing effect at low temperature. 1. Introduction
- Is acetylated castor oil a bio-based plasticizer?
- Although acetylated castor oil has excellent performance as the bio-based plasticizer and has realized industrialized production, the price of it is three to four times more expensive than phthalates, which limited its utilization (Bocque et al., 2016).
- What are the epoxidation and ring opening reactions of Bio-Base plasticizers?
- The epoxidation and ring opening reactions were mainly investigated through GC-MS analysis. The structures of bio-base plasticizers (a, b and c) were confirmed by Fourier transform infrared spectroscopy (FT-IR), 1 H NMR and 13 C NMR. The mechanical properties of a/PVC were as good as those of PVC films with the dioctyl phthalate (DOP) plasticizer.
