been carried out using chromium oxides, but using hypochlorite was the safer route and less expensive route (1). The reaction performed was an exothermic reaction. As bleach was added to the reaction mixture, which consisted of 2-octanol, glacial acetic, and reagent grade acetone, the temperature began to rise. The key thing during this experiment was adding the bleach at a slow, steady rate, so that the temperature didn’t exceed 40. Once this part of the reaction was complete, starch iodine tests

first experiment was done on a compound which is commonly known as a triglyceride which contains three fatty acids and a glycerol backbone. The next experiment was done one a caffeine which is a hetercylic ring. However, this heterocyclic ring has all oxygens in the place of the carbons. The third eextraction was done on benzoic acid and acentanilide and the last experiment was done on acetic acid to purify an ester. The first of these many experiments was the extraction of trimyristin from nutmeg. Trimyristin

Experiment Three Report Riboflavin Fluorescence Spectra Name: Holly Experimental Section: Include all details on preparation of standard solutions. Also include the vitamin tablet brand name; the listed mass of vitamin B2 per tablet; procedure used for extraction of the tablet and dilutions performed. The experiment began by determining the best wavelength at which to excite the riboflavin molecule, by examining the graph given in the laboratory manual[1]. Because plastic cells that absorb

fluorine doped tin oxide (FTO) electrospun on glass substrate were prepared. These transparent conductive films were prepared at a substrate temperature in the range 350-550 οC. A solution of SnCl2.2H2O in methanol and glacial acetic acid was used as a precursor. Hydrofluoric acid was added to the precursor solution as a dopant. The films were prepared in one single step and no further treatment is required. The distance between the spray nozzle and the substrate was in the range 2-10 cm, the liquid

The attractants like apple cider vinegar, wine, or tequila contain acetic acid molecules and hence the fruit flies are attracted to them. Apple Cider Vinegar Fruit Fly Trap: I can bet, you will hear the name of apple cider vinegar traps every time, someone talks about fruit fly traps. Apple cider vinegar is one of the most

that become vapours quickly so they are present in perfumes. Ethyl ethanoate is made from ethanol and ethanoic acid. In the reaction sulphuric acid is added as a catalyst. On a large scale ethanol and ethanoic acid is added to get the product ethyl ethanoate and water. Ethanol + Ethanoic acid  ethyl ethanoate + water The smell of the product is the the reaction proceeds. The ethanoic acid in the reaction is neutralised by adding sodium hydrogen carbonate and few drops of the mixture is added to the

Introduction Ways to Synthesize Acetanilide The goal of this experiment was to synthesize acetanilide form aniline and acetic anhydride. Even though this was the reactants used in the laboratory, there are other reactions that would result in the same compound. One way to produce acetanilide is to use aniline but to replace the acetic anhydride with acetonitrile and add deionized water. Even though this reaction has a ninety-eight percent yield, the consequence is that the reactants need to be heated

Clostridia usually has two phases, acidogenesis and solventogenesis (Lee et al., 2008). In the acidogenesis phase, glucose or other sugars are converted into acids such as acetate acid and butyrate acid, which leads to rapid decrease in pH. Under certain critical pH, Clostridia shifts to the solventogenesis phase during which it consumes acids to produce solvents (acetone, ethanol and butanol). The most important factor that triggers the shift from acidogenesis to solventogenesis is external and internal

The main purpose of this experiment was to synthesize an unknown ester using Fischer esterification reaction between an unknown carboxylic acid and an unknown alcohol as reactants as well as sulfuric acid as a catalyst. At the first step, the reaction mixture was created using the two key reactants, then the product was isolated by removing the aqueous layer. Through the distillation process, the crude product was purified to generate a clear liquid with a banana like odor as a final product of the
