Synthesis of Tetrachloro-Bisphenol A by Chlorination of Bisphenol A

The Journal of the Society of Chemical Industry, Japan, 1971
一般液相塩素化触媒を用い, 酢酸溶媒中で BPA の塩素化を行ない, 塩化アルミニウム触媒が最も適当な触媒と認めた。反応条件は BPA 仕込み濃度 10%, 触媒濃度 1% 以上, 反応温度 30～33℃ が適切であった。触媒の選択作用は強く, 無触媒とは異なった選択逐次反応で進行する。Cl2流速/BPA (l/min・mol) 0,25～0.60 の各実験における BPA の消失速度から擬一次反応の成立が確認され, その速度定数たと反応時間tの積τ と BPA,反応中間物の濃度の関係はほぼ同一曲線上にプロットされた。その曲線から, 試行錯誤により求められた各中間物の相対速度定数Kは, K2=k2/k1=1.3, K2=k3/k1=1.2, K4=k4/k1=1.8, K5=k5/k1=≒0 ...

Glyoxylic‐Acetal‐Based Gel‐Polymer Electrolytes for Lithium‐Ion Batteries

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
A safe electrolyte based on tetraethoxyglyoxal (LE) is combined with a methacrylate polymer matrix. The resulting gel‐polymer electrolyte (GPE) exhibits an increased flash point, suitable ionic conductivity, and a stable performance in lithium‐ion battery cells.

Magnetic lipase B from Candida antarctica (CALB) biocatalyst for integrated valorization of tilapia by‐products and biodiesel biorefining

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The immobilization of lipase B from Candida antarctica (CALB) on an amino‐epoxy functionalized magnetic support (Fe3O4‐PEI‐DGEBA) resulted in a highly stable and efficient biocatalyst for biofuel production from tilapia oil. The synthesized support was characterized using scanning electron microscopy, transmission electron microscopy, X‐ray ...

Urinary Bisphenols as Biomarkers of Exposure to Bisphenol A, Bisphenol F, and Bisphenol S: A New Procedure for Biomonitoring

Laboratories
Introduction. Bisphenols are chemicals widely used in industrial production, but they are also of significant concern due to their potential health effects. In particular, bisphenol A (BPA) is a documented endocrine disruptor. As a result, bisphenol S (BPS) and bisphenol F (BPF) are now frequently used as substitutes.
