Abstract A polyester plasticizer (RSOP) for polyvinyl chloride based on rubber seed oil (RSO) was synthesized. Firstly, RSO monoglyceride were synthesized by the transesterification of with glycerol at 220–240 °C. Secondly, RSOP from and adipic acid esterification. The characterized GPC, FT-IR, 1 H NMR DSC. Plasticized (PVC) materials dioctyl phthalate (DOP) in varying ratios prepared via therm...

Abstract There is growing interest in biodegradable and bio‐based materials that can replace conventional plastics applications such as packaging. Polymers based on 2,5‐furandicarboxylic acid (FDCA) have been proposed analogues for polymers terephthalic acid. However, they tend to be brittle, exhibit limited biodegradability, there are few examples of biocomposites from these polymers. Describe...

The dicarbonylation of 1,3-butadiene to adipic acid derivatives offers the potential for a more cost-efficient and environmentally benign industrial process. However, complex reaction network regioisomeric carbonylation isomerization pathways, make selective direct transformation particularly difficult. Here, we report surprising solvent effects on this palladium-catalysed process in presence 1...

We report on the synthesis of a series poly(ester-anhydride) composed following dicarboxylic acids: adipic, suberic, sebacic, dodecanedioic acids; and hydroxyalkanoic ricinoleic 12-hydroxystearic acid with control molecular weight approaching from new method in which well-defined ester monomers are first synthesized by stepwise addition acids molecules into melted acids. The key advantage this ...

A visible-light-active photocatalyst, SnP/AA@TiO2, was fabricated by utilizing the coordination chemistry between axial hydroxo-ligand in (trans-dihydroxo)(5,10,15,20-tetraphenylporphyrinato)Sn(IV) complex (SnP) and adipic acid (AA) on surface of TiO2 nanoparticles. The SnP center strongly bonded to nanoparticles via linkage as confirmed various instrumental techniques. SnP/AA@TiO2 exhibited re...

• Fungal and shrimp chitosan were wet spun to monofilament yarns. Using adipic acid as solvent generally resulted in fibers with higher tensile strength compared obtained using lactic acid. Chitosan monofilaments showed a similar or better biocompatibility commercial sutures. are good candidates for being used Purified fungal crustacean by acids solvent. The lowest viscosity at which fiber form...

Mixed yeast elongator-tRNAs (bulk tRNA lacking fRNAm,fMet), pure isoaccepting species of elongator-tRNAs (tRNAmMet and tRNAPhe), and purified initiator-tRNA (tRNAfMet) were each oxidized with periodate and the 3' terminus was coupled to Sepharose 4B through an adipic acid dihydrazide spacer. The rat liver ribosomal proteins that associated with the tRNAs were isolated by affinity chromatography...

Biomass-derived chemicals can offer unique chemical functionality relative to petroleum-derived building blocks. To this end, here we report that ?-ketoadipic acid (?KA), a C6 diacid with ?-ketone group, be used as performance-advantaged replacement for adipic in nylon-6,6 analog. Building on our previous efforts produce shikimate-derived products from carbohydrates, Pseudomonas putida KT2440 i...
