A similar reaction in the presence of potassium bromide was found to preferentially produce corresponding brominated derivatives. These reactions seem to proceed through PAHs adsorbed on the silica surface and halogenating agents, the electrophilicity of which may be raised by the catalytic effect of ...
Two principal methods are used for the preparation of aqueous solutions of chlorine dioxide for water treatment (Masschelein, 1967; Gall, 1978). The first is the reaction of sodium chlorite (NaClO2) and chlorine (Cl2) in acidic aqueous solution, primarily by the following equation:(4)H...
(17.73) depend on the reaction conditions. In the ClNO3 molecule the chlorine atom is bonded to oxygen so the linkage is ClONO2. Dichlorine monoxide also reacts with metal chlorides, and the reaction with SbCl5 can be represented by the equation...
and some paints. Following are some of the more importantcompounds of chlorine used in industries: hydrochloric acid (HCl + H2O), table salt (NaCl),chloroform (CHCL3), carbon tetrachloride (CCl4), magnesium chloride (MgCl2), chlorinedioxide (ClO2), potassium chloride (KCl), and lithium chloride...
What mass of potassium chloride can be produced directly from 5.5 grams of potassium and 7.8 grams of chlorine? 2K + Cl2 arrow 2KCl How many moles of KCl are produced from 128.17 grams of HCl and excess KOH? HCl + KOH arrow KCl + H2O If this r...
Excess of nitrite, after reaction with aniline, sulphanilic acid or sulphanil-amide in the presence of potassium bromide, is determined by flow injection voltammetry at a glassy carbon electrode by injection of the reaction mixture into ... AG Fogg,NK Bsebsu,MA Abdalla - 《Analyst》 被引量...
Characterization of the CH Addition Product from Meta- and Ortho-Xylene + CH Reaction and Direct Experimental Observation of the Tetrabromine Cluster Br4 u... We present the first determination of the homoatomic polyhalogen tetrabromine, Br4, in the gas phase. Detection was achieved through the...
An even simpler way to increase the amount of sample passing the reaction zone, consists in the addition of a wick after the reaction zone glued in between the test strip and the backing card (cf. Fig. 2e). When the same material is used for the wick and the test strip, the sample ...
(van Pee and Unversucht2003). Enzymes known to mediate intracellular chlorination include FADH2-dependent halogenases and perhydrolases. In addition, biotic chlorination has been suggested to involve an enzymatic reaction, where methyl halide transferase catalyses the formation via the reaction of S-...
