Unformatted text preview: 141.6°C, a temperature consistant with the melting point of 1,9-diphenyl-1,3,6,8-nonatetraen-5-one. A TLC analysis was taken of the starting material X, crude product, and the recrystalized product in 80:20 and 90:10 hexane:ethyl acetate. The Rf values in 80:20 hexane:ethyl acetate solution were .33mm (aldehyde X), .32mm (crude product), and.30mm (recrystalized product). The Rf values in 90:10 hexane:ethyl acetate solution were .22mm (aldehyde X), .18mm (crude product), and.16mm (recrystalized product). The final weight of the recrystalized product was found to be 0.04g giving a 20.51% percent yield....
