It has greater rate of filtration (faster) and gives a purer product because the solvent is drawn into the flask with vaccum.

It will give you the corresponding NH4Cl salt (solid)

That’s the equation thats asked, right? Reaction of 2,3dimethyl aniline with HCl. It will make a salt(solid) that is water soluble. And since phenols are not so soluble in aqueous medium they will stay back when a work-up is performed

what about part lll, how would we obtain 2,3-dimethylamine from the product ?

React with a base(NaOH)

wouldnt you react it with react it with na2co3 to get rid of the impurities and then do redistillation ?

yeah sure, i just just the simplest and the first base that came to my head, so i guess Na2CO3 would work too
just try and understand whats the idea behind the questions- aniline being insoluble and the salt being soluble. So just knowing that is good enough i think, even if you write [Base] instead of a specific one, still works afaik
