The rates of hydrolysis of sodium dithionate in a phosphate buffer solution (0.2 mol//), sodium hydroxide solutions (0 to 1.02 mol/l) and sulfuric acid solutions (0 to 0.780 mol//) were investigated in the temperature ranges 140 to 180, 120 to 150, and 80 to 130°C, respectively. ...
In general, the lower the acid concentration the higher the amount of hydroxides/oxides formed on the metal surface. This observation is related to the possible formation of magnesium hydroxide during the HF treatment in aqueous solutions. Magnesium hydroxide can be formed by the reaction of the ...
a process for producing the above-mentioned alkoxycarbonylalkylthioaryl compound, which process comprises reacting the above-mentioned disulfide compound with the above-mentioned hydroxide of an alkali metal M 1 in the presence of the above-mentioned sulfur compound to obtain an alkali metal salt of...
Although NaOH is shown in equation I as the base utilized, any alkali metal hydroxide is suitable, i.e. lithium, sodium, potassium, rubidium or cesium. A strong base, such as the alkali metal hydroxide, is needed. When weaker bases such as NaHCO3were used, no reaction occured. At least...
