Forming Methyl Orange an Azo Die Abstract: An synthetic azo dye was created by reaction of diazonium salt with N‚N-Dimethylanaline. The final product created was 4-dimethylaminoazobenzene-4-sulfonic acid‚ an orange clay-like substance. Sulfanilic acid was chemically manipulated by using sodium carbonate followed by cooled sodium nitrate and hydrochloric acid to form the diazonium salt used in the reaction. The products were washed in ethanol. The product was obtained at an 84% yield and was

The methylene blue staining procedure is used to measure yeast viability based on the assumption that the methylene blue will enter the cells and be broken down by living yeast cells that produce the enzymes which breaks down methylene blue‚ leaving the cells colourless. The non- viable cells do not produce this enzyme (or enzymes) and as such the methylene blue that enters the cells are undegraded causing the cells to remain coloured (the oxidized form concentrates intracellularly). The coloured

Chemicals Hordenine and methyl jasmonate were purchased from Tokyo Chemical Industry (Tokyo‚ Japan). Dimethyl sulfoxide (DMSO) was obtained from Sigma-Aldrich (Tokyo‚ Japan). Plant materials Two-year-old seedlings of Vitis vinifera cv. Koshu were cultivated in perlite:vermiculite (1:1) soil in a growth chamber (11.8 Wm-2 for 14 h in a day) at 27 °C. Seedlings of Fragaria×ananassa cv. Nyoho were grown in 55% peat moss‚ 10% perlite‚ 5% vermiculite‚ and 30% decomposed granite soil at 25 ºC in a greenhouse

Purpose The purpose of this experiment is to determine the rate constants‚ k1‚ for the methyl acetate hydrolysis reaction at 25 °C and 35 °C‚ as well as the overall activation energy of the reaction. Methods Methyl acetate was placed in an HCl solution‚ in which it reacts with water to form acetic acid over time. At each time interval‚ an aliquot of the mixture was removed for titration against NaOH to determine the concentration of the acetic acid produced. From the amount of acetic acid produced

Synthesis of Benzanilide and Methyl 3-Nitrobenzoate and the Identification of ‘Unknowns’ from Spectroscopic and Physical Properties James Lucas 10394308 23/11/12 Introduction In this series of practicals it was the aim to synthesise both Benzanilide and Methyl 3-Nitrobenzoate. Benzanilide was synthesised using The Schotten Baumann reaction which takes a hydrogen atom from an amino group and substitutes it for an acyl group. For Methyl 3-Nitrobenzoate‚ NO2+ was used as an

Experiment #5: Esterification of Methyl Benzoate from Benzoic Acid October 28‚ 2010 Abstract: This experiment was conducted to synthesize methyl benzoate from benzoic acid and methanol by using the Fischer esterification method. Methanol (12.5ml) and Benzoic acid (4.9 grams) are heated together in the presence of concentrated sulfuric acid (1.5ml) until equilibrium is achieved. A reflux apparatus is set up for 1 hour to carry out the reaction at the boiling point of the solvent (Methanol
