Abstract The homophase polymerization of acrylic acid is carried out in a solution poly(butyl acrylate) trithiocarbonate (PBATC) mixed solvent 2-propanol–water. phase diagram the three-component PBATC-2-propanol–water system at 22°C obtained. region compositions semidilute solutions determined. AA 70°C, which with respect to PBATC similar thermodynamic quality θ-solvent 22°, yields narrowly dis...

The extraction and transesterification of soil lipids into fatty acid methyl esters (FAMEs) is a useful technique for studying soil microbial communities. The objective of this study was to find the best solvent mixture to extract soil lipids with a pressurized solvent extractor system. Four solvent mixtures were selected for testing: chloroform:methanol:phosphate buffer (1:2:0.8, v/v/v), chlor...

Bisphenol A (BPA) is metabolized by a Gram-negative aerobic bacterium via a novel pathway involving oxidative skeletal rearrangement of the BPA. Oxidation of the aliphatic methyl group of BPA leads to coproduction of the methyl-hyroxylated 2,2-bis(4-hydroxyphenyl)-1-propanol and a skeletally rearranged triol 1,2-bis(4-hydroxyphenyl)-2-propanol. The major route of metabolism (> 80%) is through t...
