Aldol Condensation Conclusion In this lab experiment, we synthesized at a yield of 12.70% an enolate from acetophenone, and used the enolate to perform an aldol condensation with 4-nitrobenzaldehyde to produce 4-nitrochalcone, a dehydrated product of the aldol condensation. The low yield of 12.7% can be attributed to several causes. For one, I was careless in transferring my product; I spilled product almost each time I attempted to move the product from filter paper to filter paper, and from filter paper to weighing paper. Even when I was scraping the product from the flask into the beaker I lost product, and not all product was completely scraped off into the beaker. Adding all of these little losses provides for a much greater overall loss. There needs to be a more efficient way of transferring to minimize loss. Another large source of error occurred through the filtration process. When the product was filtered through vacuum filtration, a significant amount of product could be seen in the filtration flask. This is due to the degree to which the filter paper is porous, and using a less porous filter paper would help
