DescriptionSodium carbonate( 497-19-8), Na2CO3, is a sodium salt of carbonic acid. The pure product appears as a while, odorless powder with a strong alkaline taste. It has high hygroscopicity. It can be easily dissolved in water to form an aqueous solution with moderate alkalinity. ...
Reactivity of the active sodium carbonate towards the hydrogen chloride is lower as compared with its reactivity towards the sulphur dioxide. A relationship was found between the reactivity of the solid and the way of its preparation. The inactive form of the sodium carbonate is inactive towards ...
Process for producing sodium carbonate from the sodium amalgam of mercury-process salt electrolysis, wherein a caustic soda solution is reacted with carbon dioxide gas to produce sodium carbonate which is further subjected to crystallization and separation and a mother liquid resulted from the crystal...
Thereaction was quenched by addition of aqueous methanol, concentrated in vacuoand purified by flash chromatography on silica gel (methylenechloride:methanol, 87:13) to give the title compound (44 mg). 三、硼氢化钠(钾)还原羧酸酯成伯醇示例 ...
A method for solution mining nahcolite, capable of extracting nahcolite from geological formations lean in nahcolite comprising injecting high pressure water (which may include recycled aqueous solution of bicarb and sodium carbonate) at a temperature of at least 250° F. into the formation, dissol...
