April Goodson CHEM 242L-002 February 20‚ 2013 Oxidation of Cyclohexanone to Adipic Acid Abstract The cyclic ketone cyclohexanone was oxidized to adipic acid using the oxidizing agent nitric acid. The experiment yielded 0.2667 grams of adipic acid‚ giving a percent yield of 113.97%. Although the product was allowed to dry for one week‚ residual moisture was still present in the sample and a melting point could not be obtained. This error in the experiment either resulted from adding too much

Clays are one of the important natural materials‚ which have been examined for catalytic applications. Clays are characterized by a layered structure and hence they are slippery when wet. They are broadly classified as cationic or smectite type (having layer lattice structure in which two-dimensional oxyanions are separated by layers of hydrated cations) and anionic or brucite type (in which the charge on the layer and the gallery ion is reversed complimentary to smectite type). Anionic clays are

Synthesis and Structure of Alcohols Alcohols can be considered organic analogues of water. H O H R O H Alcohols are usually classified as primary‚ secondary and tertiary. H R H OH H primary R R OH R R OH OH R secondary tertiary phenol Alcohols with the hydroxyl bound directly to an aromatic (benzene) ring are called phenols.

your body can cause dizziness‚ nausea‚ headaches and fatigue. Bad Breath Low-carb diets lead to incomplete burning of fats to produce energy in your body‚ and in the process‚ ketones are produced‚ says Anssi H Manninen‚ an exercise physiologist specializing in sports nutrition and ergogenic aids. Excess ketones in your body come out through your urine and saliva. This causes bad breath among people on low-carb diets. Though you cannot do much to stop bad breath‚ drinking water and chewing sugar-free
