Hello Friends !
I have some work-up problem in my solvent media.
I made one Amine HCl in n-Butanol media by acidifying the Amine dissolved in n-Butanol with hydrochloric acid. Due to this acidification, the butanol remains acidic & distills also as acidic when I concentrate it to get the Hydrochloride salt.
Here, my problem is I can not distill this acidic n-BA in my plant as I have only the SS reactor which can not suffer the acidic vapor or solvent.
I tried adding NaHCO3 to this and made around 5-6 pH, but even at this slight acidic stage, some hydrochloride salt breaks out to the Amine !
Can anyone pls suggest me something that how I can neutralize this n-Butanol+Amine HCl mixture so that my hydrochloride salt remains protected & solvent gets neutralized !
Pls suggest at earliest !
Thanking you in advance,
Kamal
