This thesis covers the practical research done on the condensation of thioacetophenone with benzaldehyde and the library research covers the chemistry of thioketones and the thioflavanones. Most of the thioketones have been made by dissolving a ketone in ethanol, usually absolute although 95 percent was also used, saturating the solution with anhydrous hydrogen chloride at ice temperature, then admitting hydrogen sulfide for several hours. This method was first used by Fromm and Baumann when they made thioacetophenone from acetophenone. David Shirley also gives theis process in his book “Preparation of Organic Intermediates” published by Wiley and Sons in New York. SOmetimes a metallic oxide dehydration catalyst such as alumina is used.
