Synthesis and evaluation of N,N-dibutylundecenamide as new eco-friendly
Tertiary fatty amide, namely N,N-dibutylundecenamide (DBUA), has been synthesized and evaluated as potential plasticizer for polyvinyl chloride (PVC). Homogeneous PVC/DBUA composite films containing 20, 30 and 40 wt% of DBUA were prepared by solvent casting. Infrared analysis of PVC/DBUA blends indicated molecular interactions between polar –CH–Cl group of PVC and carbonyl group of
Current Status of Plasticizer Research | SpringerLink
3.5.3 New Environmentally Friendly Plasticizers. Plasticizer producers should increase the R&D investment to develop new products and circumvent the technical barriers to win the international market. Currently, the research on environmentally friendly plasticizers obviously falls behind the practical needs.
Development of a Highly Efficient Environmentally Friendly Plasticizer
The new environmentally friendly plasticizer has good compatibility with PVC and high thermal stability. The effectiveness of the plasticizing action of adipate based on the...
Synthesis and evaluation of N,N-dibutylundecenamide as new eco-friendly
Overall, the obtained results indicate that tertiary fatty amide DBUA is promising eco-friendly plasticizer for PVC which combines good low-temperature performance, high biodegradability, as well
A highly stable bio-based plasticizer constructed from renewable acids
The results of optical performance showed that, compared to ATBC and DOP, PVC plasticized by 50 phr LLMEE had both high transparency and UV resistance. According to the results of tensile tests, the elongation at break of PVC plasticized by 60 phr LLMEE reached 833.1%, indicating its excellent mechanical properties.
- Which plasticizer has a strong migration resistance?
- Hyperbranched plasticizer has strong migration resistance due to its unique structure. Lactic acid-based plasticizers are a very cutting-edge direction that requires more research and development. These bio-based plasticizers can give PVC materials excellent thermal and mechanical properties under the premise of resistance to migration.
- Are plasticizers compatible with PVC?
- By analyzing the relationship between molecular structure and performance of plasticizers, researchers found that the presence of carbon–carbon double bonds and hydroxyl groups reduces the compatibility of plasticizers with PVC, while the epoxy groups and ester bonds can improve the plasticizing capability of plasticizers on PVC.
- Why is cardanol a suitable raw material for bio-based plasticizers?
- In summary, cardanol is a suitable raw material for the preparation of bio-based plasticizers due to the benzene ring, phenolic hydroxyl group and unsaturated double bond on its molecular structure as well as its abundant biomass source.
- What are natural biodegradable plasticizers?
- Natural biodegradable plasticizers can be isolated from the agro products and litters that are cost-effective, sustainable, and huge abundant. Several natural plasticizers originate from agricultural products like trees, oleaginous plants, cereals, vegetables, and fruits, as well as their waste .
- What are ESO plasticizers?
- Common ESO plasticizers have been fully studied, so the focus of research is mostly on the functionalization, designing new structure and process optimization of soybean oil-based plasticizers . He et al. used α-Al 2 O 3 ·H 2 O as the catalyst for the epoxidation reaction and H 2 SO 4 as the catalyst for the ring-opening reaction.
- What is the best plasticizer for PVC films?
- Thermal and mechanical properties of PVC films are shown in Table 1. For PVC, AcMAE-C6 was found to be the most effective plasticizer (780%), followed by AcMAE-C8 (757%), AcMAE-iC8 (729%), AcMAE-iC13 (595%), and AcMAE-C4 (477%). The results showed that AcMAE-C6 and AcMAE-C8 showed better plasticizing properties than DOA and DEHP.
