The first synthetic sweetener‚ saccharin‚ was discovered five years prior to Dulcin. The discovery of Dulcin occurred in 1883. Approximately seven years after it’s discovery‚ J.D. Reidel‚ of Berlin‚ was able to synthesis Dulcin at a reasonable cost. Once it became possible to synthesis at a reasonable cost‚ mass production of the sweetener began. Dulcin was favored over its competitor‚ Saccharin‚ because it did not possess a bitter aftertaste. For a very brief period of time Dulcin was marketed

Abstract – This multi-step synthesis uses aniline as the starting reagent to synthesize five compounds employing several reactions such as acetylation‚ diazo coupling‚ nitration‚ bromination‚ and hydrolysis. The isolated products were analyzed with TLC and spectral data that determined most products were pure while some had a few impurities indicated by GC‚ LC‚ and a wide melting point range was shown for products 2 and 3. The presence of water in product 2 and 7 was indicated by the IR. Acetanilide

For over the past several years each student is given 3 containers‚ each with 1 larva‚ which they had to care for. After the larvae had formed their chrysalises each student put 1 of their containers into a cold climate approximately 45°F‚ 1 in a warm climate approximately 85°F and 1 stayed out at room temperature approximately 72°F. The larvae spent a total of 5 days in each climate‚ and then they were removed and brought back to room temperature. Then the waiting game started to see how long it
