Would someone be so kind as to give me their opinion on the following
reaction:
I am trying to form an ester from a zwitterionic acid compound using
different long chain or aromatic alcohols and HCl gas as the catalyst. I add
molecular sieves 3angstroms to absorb the water formed so that the reaction
continues in the forward direction. It only takes 10 minutes for something
to occur and with a little bit of heat (40C) then a residue is formed in 5
minutes. This residue looks different to the starting material but I am not
sure if it is just that the alcohol has evaporated off even at such low
temps. Would enclosing the reaction with a solid catalyst be a better idea
and if so should the temperature or pressure be controlled?
Thank you
Marie
