Plasticizers Derived from Biomass Resources: A Short Review
Ester-amide of ricinoleic acid, as shown in Figure 22, is synthesized and used as primary plasticizer to replace phthalate plasticizers in PVC materials [ 105 ]. Tg of PVC materials blended with 40 wt % of ester-amide of ricinoleic acid reaches 13.5 °C. Figure 22. Synthesis of ester-amide of ricinoleic acid.
Synthesis of an efficient bio-based plasticizer derived
In order to develop an efficient and sustainable plasticizer, the waste cooking oil and malic acid were used as the main raw materials in this study to synthesize a bio-based plasticizer (acetylated-fatty acid methyl ester-malic acid ester, AC-FAME-MAE) by environment-friendly methods, and the structure was characterized by FTIR and 1 H NMR.
Recent Attempts in the Design of Efficient PVC Plasticizers
A series of palm oil-based plasticizers prepared using palm oil, glycerol, phthalic anhydride, acetic acid, and calcium hydroxide in different compositions was proposed by Rozaki et al. in 2017 . These plasticizers exhibited varying molecular weights (from 2279 to 9560 g/mol) and caused a decrease in T g when compared with neat PVC, but was not
Bis(2-ethylhexyl) terephthalate
This colorless viscous liquid is used for softening PVC plastics and is known for chemical similarity to general purpose phthalates such as DEHP and DINP, but without any negative regulatory pressure. It possesses very good plasticizing properties and may be used as a direct replacement for DEHP and DINP in many applications. Production [ edit]
Synthesis and properties of castor oil based plasticizers
The mechanism and modeling of the thermal degradation of PVC samples mainly at 10°C/min have been reviewed and discussed. 55 In the literature, the TGA traces of plasticized PVC films have...
- What is the best catalyst for palm oil methyl ester conversion?
- The study shows that methanesulphonic and sulphuric acid were the best catalysts and reaction with methanol obtained greater yields. At optimized reaction conditions a palm oil methyl ester conversion up to 100% could be achieved in transesterification using the liquid core encapsulated lipase .
- What is epoxy fatty acid methyl ester?
- Epoxy fatty acid methyl ester Description: Epoxy fatty acid methyl ester is colorless or light yellow liquid at ambient temperature. It is a new type of environmental friendly plasticizer with vegetable oil as raw material. It can replace all kinds of main plasticizers such as DOTP, DOP, DBP, DINP, TBC, DINCH and so on.
- Can palm oil methyl ester be used as an additive?
- Masjuki and Maleque , used palm oil methyl ester (POME) as an additive in application of sliding wear of cast iron against mild steel. In the study pure diesel oil, pure POME and formulated diesel oil blended with different percentages of POME as an additive were studied.
- What is the difference between DOP and plasticizing efficiency?
- 8. Plasticizing efficiency is higher than DOP, it can reduce the total amount of plasticizer.
