: Jun. 12‚ 2009) Abstract : 2-Acetylcyclohexanone was synthesized by acylation reaction of acidic anhydride using enamine as organiocatalyst instead of a strong base‚ NaOH‚ resulting in milder reaction conditions. The reaction was conducted in toluene and direct distillation of the reaction mixture before hydrolysis was leaded to a high yield of the pyrrolidine enamine. This condition was leaded good yields (73.6%) without side reactions. Acylation gave an enol form (71.7%) and a keto form (28

These functional groups are removed by using a basic solution as shown in (i) below1. The product formed with water is stable only due to resonance‚ but does

The basic ingredients are Formaldehyde‚ DBP‚ and Toluene. Also‚ formaldehyde is a chemical that helps harden your nails‚ but is is also harmful as it is proven to cause lung cancer. DBP or Dibutyl Phthalate‚ makes the nail polish a little more flexible and less prone to chipping. Many companies are changing

this experiment was to separate Toluene and Hexane by distillation and gas chromatography based on their difference in boiling points. The boiling point of hexane is 69 degrees Celsius and the boiling point of toluene is 110 degrees Celsius. Three fractions were collected for both simple and fractional distillation. The first fraction was hexane since it had the lower boiling point. The second fraction was a mixture of toluene and hexane. The third fraction was toluene since it had the high boiling
