Asolventless aldol reaction one week labi the intent of this lab to carry out a mixed aldol reaction using "green" methodology e introduction condensation represents a powerful general method for the construction of carbon-carbon bonds orming a mixed one of the central themes of synthetic organic chemistry. in this experiment we will be pert aldol condensation of 3,4-dimethoxybenzaldehyde and 1-indanone in contrast to typical experimental procedures, this reaction is waste and make any synthesis more "green" are a welcome and developing trend in modern chemistry. carried out wi t solvent. efforts thout to reduce parta experimental- the reaction 3,4-dimethoxybenzaldehyde (0.25 g). 3m hc1 (2 ml), stirring rod. 1-indanone, naoh. a lab with glassware, organie and inorganic compounds, useful hints. objective: present the written group plan to your instructor that outlines how the aldol reaction of 3,4-dimethoxybenzaldehyde and 1-indanone is to be carried out. your plan must be approved before proccedins. hints: mix equimolar amounts of 3,4-dimethoxybenzaldehyde and 1-indanone in a cylindrical vessel with optimal surface area. be gentle with your stirring. but not too gentle. seeing a brown oil is a good thing before the next step. add freshly ground naoh (0.8 molar ratio with the aldchyde) and continue stirring. seeing the mixture turn solid is a good thing. wait 15 minutes and isolate the crystals using the aqueous 3m hci (the overall solution must be acidic). how do you check for this? isolate the crude crystals and dry them in an efficient way (no oven). record the crude yield before you forget it. part b experimental-recrvstallization of the impure product given: slightly damp crude product from part a. objective: present a written plan from your group that describes how the crude product is to be purified. calculate the theoretical yield of product. note: a complete group plan details a % yield calculation.
