Sodium carbonate analysis issues
Thread Content
Some of our mixtures contain sodium carbonate among the {organic substances}, which gives the material an alkaline nature with a pH of around 8-9. We would like to know the amount of sodium carbonate present in these mixtures; could someone please advise us?
Take two equal amounts of the sample: one is analyzed for its total alkali content, while the other is treated with barium chloride to determine its sodium hydroxide content; the total alkali content minus the sodium hydroxide content gives the sodium carbonate content
The issue mentioned by the poster should be the analysis of sodium carbonate in the material at the bottom of the reactive distillation tower during the production of dimethyl carbonate. The following relevant **standards can be queried
