Benzocaine
« on: May 26, 2006, 01:14:38 PM »
In making benzocaine, I added ethanol to p-aminobenzoic acid, then added H2SO4 which caused precipitation.  After refluxing, I added Na2CO3 to neutralize the mixture.  The pH was at least 8.  I need to know why benzocaine precipitates during neutralization and I need a balanced equation for the neutralization of the benzocaine product using structural formulas.

Thanks for your help.

protonating the amino group makes it ionic therefore more polar and soluble in water
