name of thiamine hydrochloride may be used to catalyze the benzoin condensation, which is preferable to using cyanide. This experiment will test whether thiamine can effectively catalyze the reaction (2). The experiment begins with the condensation of benzoin (eq. 1). In the presence of the thiamine catalyst, the 2 benzaldehyde molecules condense to produce benzoin when they are heated with sodium hydroxide and ethanol. Equation 1: Benzoin Condensation. The production of benzil (eq. 2) is a redox
The substance that seems most interesting is benzoin, which is characterized in two of the functional groups mentioned. It is involved in many different processes and is widely used in foods, mainly baked products. Benzoin is viewed as off-white crystals, with a slight camphor odor. A camphor smells of vanilla with a slight medicinal scent. The substance's formal hydrocarbon chemical name is 2-Hydroxy-1,2-diphenylethanone. Many other names for Benzoin includes 2-Hydroxy-2 – phenyl acetophenone benzoylphenyl
was to identify the three components in the mixture and to determine the percent recovery of each from the mixture. 4) Separation of a Neutral and Basic Substance A mixture of equal parts of a neutral substance containing either naphthalene or benzoin and a basic substance containing either 4-chloroaniline or ethyl 4-aminobenzoate were to be separated by extraction from an ether solution. Once the separation took place, and crystallization was carried out, it became possible to determine what components
