Question about imines
Q:
Today in lecture, you were showing us how an amine can react to form
an imine by reacting with a carbonyl compound and acid. You also said
that the imine can be hydrolyzed back to the amine and carbonyl
compound by adding aqueous acid. One of the products of the reaction
you showed us today was water, so does that water and the acid thats
already present hydrolyze the imine back to the amine and ketone to
some extent to form an equilibrium? Also, is there a way to minimize
the hydrolysis back to the amine and ketone and keep the imine?
A:
Yes, it is an equilibrium. If you remove water you can drive the formation of the imine. Water can be removed using molecular sieves or distillation, depending on the reactants.

I wondered if molecular sieves could be used as an emergency containment system for absorbing CBR (Chemical, Biological, Radiation) materials? From what I could find the answer is….they can probably be useful in absorbing CBR discharges from weapons.
You should add trackbacks to your site.
As ever,

Jonathan,
Molecular Sieves are mainly used to trap small molecules like water. So they can be added to solvents to keep them dry. I don't think they could be used for biological agents.
I thought I needed to use Typepad to be able to add trackbacks.
