Introduction in an aldol condensation, two molecules of aldehyde or ketone are joined together along with the loss of water. Synthesis of dibenzalacetone by sandy thea san carlos on prezi. For example, in the aldol condensation shown in figure 1, two molecules of ethanal are reacted to produce an a,bunsaturated aldehyde and water. Synthesis of dibenzalacetone by the aldol condensation. Patchbased texture synthesis creates a new texture by copying and stitching together textures. Using the caboncabon bond making ability in carbonyl chemistry, dibenzalacetone is synthesized from 2 equivalent.
We take advantage of neural techniques to provide adequate styl ization at the global level and use their output as a prior for subsequent patchbased synthesis. Dibenzalacetone trans, trans 1,5diphenylpenta1,4dien3one is prepared by the aldol condensation of acetone with excess benzaldehyde. In this paper, we develop a general method for patchbased. Aldol condensation of ethanal to understand the aldol. Image inpaiting is an important task in image processing and vision. Patchbased synthesis involves a user providing one or more exemplar images to an algorithm, which is then able to automatically synthesize new output images.
