Hello Friends !!

I'm performing one reaction in which I'm using Sodium Metal to reduce =
the oxime for making Amine in n-Propanol. In this manner, besides Amine =
I'm getting Sodium-n-Propoxide salt as a by-product which remains as =
solid in vessel after concentration & being so difficult to discard. =
However, it is soluble in water & but I'm looking for such possibility, =
if I can break this salt & can get n-Propanl back again as recovered !

My reaction is :
CH3CH2CH2OH + Na + Oxime ________\ CH3CH2CH2ONa + Amine + 1/2 H2
                                                             /

By the way, looking at one guessing, I passed HCl gas after the =
reduction in the reaction mixture which is mixture of Propoxide salt + =
Amine in n-Propanol. I assumed to perform making Amine Hydrochloride =
Salt as under :


CH3CH2CH2ONa + Amine + HCl (g) _________\ CH3CH2CH2OH + Amine =
HCl + NaCl
                                                                         =
  /


CAN ANYONE PLS SUGGEST ME SOME BETTER WAY TO BREAK THIS PROPOXIDE SALT & =
RECOVER THE n-PROPANOL ?




Thanks a lot in advance,
KAMAL
