mass, so obtained, is neutralized to the methyl orange indicator endpoint, so as to neutralize all sulfonic acid radicals present by means of caustic soda. The material then is dissolved in several times its volume of water and extracted with a suitable solvent, such as petroleum ether, benzol...
About 0.76 g (0.02 mmol) of LiAlH4 was suspended in a mixture of 75 ml of diethylether and 25 ml of tetrahydrofuran (dried over LiAlH4). The mixture was cooled to 0° C. in an ice bath. Then 1.35 g (0.01 mmol) of AlCl3 was added in small portions and the mixture was stirred ...
Formaldehyde, 37% --- 81 HC1 (concentrated) --- 1.5 Monoalkyl (Cio-C2o, principally Cz-C14) benzene monosulfonic acid sodium salt -- .8 60 Xylene --- -- 150 Diethyleneglycol diethylether ---This phenol was solid. The phenol, xylene, diethyleneglycol diethylether, and hydrochloric acid...
Under proper conditions of use, examples of suitable ethylenically unsaturated monomers can include acrylic acid, methacrylic acid, vinylsulfonic acid, vinylbenzylsulfonic acid, vinylbenezenesulfonic acid, vinyl acetate, acrylonitrile, methyl acrylonitrile, vinyl alkyl ether, vinyl chloride, maleic ...
This could be as a result of the limitation to mass transfer and inhibition effects. Chen et al. [127] investigated the desulphurization ability of bacterium Mycobacterium sp. ZD-19. The result showed that TH and BTH were completely removed in 10 and 42 h, respectively. Also, about 100% ...
