Dear Rakesh Mishra, to get a really useful answer to your question you should provide a few more details, e.g. is this a new reaction or a literature procedure, is your product soluble in water or ethanol, what is the nature of your product etc.
Dear all, I suppose ethanolic solution is that of KOH. If it is the case, neutralize the KOH by passing CO2 gas to form KHCO3 which precipitates in ethanol. However, the question environment is a bit ambigous. My Regards
Dear Frank T. Edelmann, I have to do EDC/NHS coupling of caffeic acid. For this firstly, I dissolved caffeic acid in ethanolic aqueous solution and then added remaining ingredients accordingly. I would like to know after completion of the reaction, how to collect the product?
