Dibenzalacetone Synthesis PURPOSE: purpose of this lab exercise is to synthesize dibenzalacetone by means of an aldol condition. INTRODUCTION: Wow, is it wet in here or what? That's what happens when you condense, right? No, that is not right, you say! You can condense things without getting wet in organic chemistry. Think about aldol condensations, you tell me. Yes. yes..of course you are correct: organic condensations dont get you wet. They get you a new product. Silly me Aldol condensation...
