Kind of a difficult question. Should have included that the base used is nBuLi and the quench is to pour the mixture into an ice water slurry. Most of the acrolein will polymerize quite fast in water and precipitates out. Acrolein will polymerize if left at RT as well, so I am wondering if expediting the process with a gentle heating may do the trick with vigorous stirring. Though I dont want entrapment to happen with my compound. But may be worth it to get the small oligomers out. The last time I did this reaction, after the work up I distilled and the pot got very viscous.....what yall think I should do??
