According to the present invention, chloride(Cl2) generated in an anode chamber when electrolyzing water via electrolyte is contacted with a drain of sodium hydroxide (NaOH), thereby preparing sodium hypochlorite (NaOCl) solution having excellent bleaching effects. As the sodium hydroxide (NaOH) ...
The method of sodium hydroxide preparation includes usage of reagent water solutions and solid inert electrodes separated with diaphragm. Anolyte is sulphide water solution with concentration 180-200 g/l, katholyte is water solution of NaOH with concentration 100-120 g/l barbotated with technical ...
A process for the preparation of a catalyst for isomerisation of alkyl aromatic compounds comprising treating dealuminated crystalline sodium mordenite with aqueous ammonium salt solution to obtain, crystalline ammonium mordenite subjecting the same to calcination by known methods treating the calcined reacti...
N-y-Chloropropylpentafiuoropropionamide (Sa) To an ice-cooled THF solution (650 ml) of pentafl.uoropropanoyl chloride (75.4 g, 0.402 mol) and 3-chloropropylamine hydrochloride (52.3 g, 0.402 mol), was added triethylamine (130m!, 0.932mol) dropwise during 2h with vigorous stirring under ...
The cellulose of carex meyeriana kunth (CMKC) was used as raw material, and the spinning solution was prepared by combining with polyacrylonitrile (PAN). The nano-cellulose fiber of carex meyeriana kunth (CMKN) was prepared by electrospinning. Used to remove methylene blue dye (MB) in aqueous...

Solution A20 ml Solution B20 ml ■ 制品说明 大肠杆菌经过处理后可以摄取外源DNA (Plasmid DNA、Phage DNA等),处于这种状态的细胞称为感受态细胞 (Competent Cell)。在基因工程实验中,经常要使用各种感受态细胞进行DNA的转化操作。 实验使用的感受态细胞的来源大体可以分为两种:一种是购买商品化的感受态细胞,但商品化...
The synthesized formulations were analysed for thermodynamic stability, indicating 1:0.5 (oil: surfactant) ratio to be the most stable of thyme oil nanoemulsion while 1:1 (nanoemulsion: chitosan solution) ratio of its chitosan encapsulation. These were further characterized by dynamic light scattering ...
Three-dimensional bioprinting of cell-laden hydrogels in a sacrificial support-bath has recently emerged as a potential solution for fabricating complex biological structures. Physical properties of the support-bath strongly influence the bioprinting process and the outcome of the fabricated constructs. In...
