Acetic anhydride from accetyl chloride
I have 99% pure acetyl chloride. I want to convert it into acetic anhydride .. can some where share the process for a small lab. I have tried a few
things but I'm getting a 45-50 percent concentrated acetic anhydride. How can I increase this purity level.

Are you using the reaction between sodium acetate and acetyl chloride? Is the contamination acetic acid? If it is, you should be able to fractionally
distil unless it forms an azeotrope. You could stop the contamination by drying your sodium acetate first. How is it that you have access to acetyl
chloride but not acetic anyhydride?
