Checking the math - Ketoxime formation
« on: February 16, 2004, 09:00:00 AM »
While studying Chromic's awesome write up on the buffered peracetic rxn,

https://www.thevespiary.org/rhodium/Rhodium/chemistry/peracetic.chromic.html

, I was looking for the molar equivalent of Sodium Bicarbonate to use in place of Sodium Carbonate for ketoxime formation.

Chromic's experimental example lists 126 mmol of Sodium Carbonate as 6.7 grams. At 105.98 grams per mole, wouldn't 126 mmol actually be double that (~13.34 grams)?

Any help will be greatly appreciated. Maybe my math is wrong.

yes you are correct, but i beleive Chromic was refering the amount of sodium available to react with the hydroxylamine.

Sodium Carbonate is Na2CO3 and has 2 sodium atoms
Sodium Bicarbonate is NaHCO3 and has 1 sodium atom

hope that helps
