removing quat salts
« on: September 30, 2004, 01:14:00 PM »
a certain otc product is mostly a aqueous solution of a chem swim wants, unfortunatly there is about 0.5% alkyl (C14-C18) dimethyl benzyl ammonia chloride, can swim remove this with a nonpolar extraction?

maybe extraction doesn't help - but distillation..

Qaternary alkylammonium salts with such long side chains are usually PTCs - so I wouldn't hope for too much regarding extractions...

Is there a possibility for you to distill the mixture? Should enable you to get rid of the quad...

sorry, but whats a ptc?

sorry, but whats a ptc? phase transfer catalyst?

distillation isn't an option unfortuantly.

Yes, PTC means Phase Transfer Catalyst. Their purpose is to "fuck up" layers of normally immiscible solvents, as they are soluble in both and are able to carry other molecules from one phase into the other... :(

I doubt that you will have luck with non-polar xtractions (although the benzyl group could makeĀ  big difference, regarding solubility)... but maybe you should just try it with a small amount; experiment is king!

What about alternative quat ?

What is the purpose of your quat ? Numerous quats can be substituted by another one. Depending on what you wanna do, maybe the idea is to find an alternative, instead of doing a difficult extraction. For exemple some otc quat are used to eliminate algae in swimming-pools. The quat often change with each different firm of production, so different varieties can be obtained.
