Synthesis of a Novel Bio-Oil-Based Hyperbranched Ester

The commercial plasticizer DOP is the usual main plasticizer, which is limited by the law due to its high risk of biological effects and toxicity on humans. Furthermore, because of easy diffusion to surroundings from PVC resin, phthalates have an environmental impact, which also reduce the durable performance of PVC products.

Synthesis of Bio-base Plasticizer Using Waste Cooking Oil

The structure-property analysis of bio-based plasticizers a, b and c for the PVC confirmed the following: first, the introduction of a benzene ring and ester bonds increased the polarity of the plasticizer molecules, which further improved the compatibility between the plasticizer and PVC resin; second, the higher molecular weight could reduced ...

Furan-2,5- and Furan-2,3-dicarboxylate Esters Derived

Esters of furan dicarboxylic acids (DAFs) were synthesized by a one-pot reaction between marine biomass-derived galactaric acid and bioalcohol under solvent-free conditions and were fully characterized. The catalyst amount could be reduced without loss of reaction yields using p-xylene as the material separation agent. Also, a possible mechanism was proposed for the first time. Then the ...

Occasional band cells and atypical cells with meandering nuclei were also evident. By PND 9–10, although some testes had focal granulomata (indicating that the hemorrhage was limited to focal areas and contained) (Fig. 4C), others manifested extensive coagulative necrosis, a sequel of hemorrhage (Fig. 4D). The latter were the grossly visible ...
