NaOH as substitute for KOH in methylation of amino alcohols
Reference: http://pubs.acs.org/doi/pdf/10.1021/jo01067a619
Does anyone know why NaOH would not be ideal to use in stratification step in substitute of KOH? Specifically the methylation 1-amino-2-propanol. I
know that NaOH is more hygroscopic than it's buddy, probably helping keep moisture levels lower in the final product. I would prefer not to have to
wait a week for KOH to come in the mail. (no soap making shops where i live)

In your reference, they use NaOH in one example, and KOH in another. They are just used as base in the workups. Moisture absorbance or solubility
might have played a role in their choice, but I doubt there would be much difference exchanging one for the other in this particular instance.

I always used KOH for adding solid (flakes) of base. It seems to be easier to visualize the response using KOH rather than with NaOH but I was
following procedures and wondered about it from time to time. For those who would like to read the whole article:
