3-perylenepentanol‚ M4 39‚ 51 To a solution of 3-perylenepent-4-ynol‚ M3 (0.32 g‚ 0.957 mmol) in THF (20 mL)‚ Pd/C (600 mg‚ 3 wt% on activated carbon) was added. Nitrogen gas was turned off‚ hydrogen gas balloons were used to supply H2 gas to the flask. The reaction mixture was stirred for 15 h under hydrogen atmosphere at room temperature. Ethyl acetate was added to the reaction mixture and the Pd/C was removed by filtration. Solvent was removed in vacuo to afford 3-perylenepentanol as yellow solid

A simple‚ rapid‚ specific and highly sensitive spectrofluorimetric method has been developed for the quantification of dabigatran etexilate mesylate (DAB) in bulk and capsule dosage form. A linear relationship was found between fluorescence intensity and DAB concentration in the range of 0.01-1.0 μg/ml in DMSO as solvent at an emission wavelength of 391 nm after excitation at 334 nm‚ with a good correlation coefficient (0.989). The detection and quantification limits were found to be 0.005 and 0

The Preparation of Methyl Salicylate Introduction: Esters have various smells that differ due to the types of carboxylic acids and alcohols one mixes together. This is called esterfication. The reaction is catalyzed by an inorganic acid usually H2SO4 Purpose: In this lab Methanol alcohol and Salicylic acid were reacted together to form Methyl Salicylate. This was done to determine the characteristic odour of the Methyl Salicylate. Safety: Safety goggles must be worn at all times. Methanol: Toxic

behaviour? What is going on? “Drink driving is usually defined as driving with a specific amount of alcohol in the blood‚ known as an individual’s BAC – which can be measured from blood‚ urine‚ and breath tests that estimate the number of grams of ethanol per 100ml of blood.” (Reference: article 1) How is the behaviour performed? When? Where? Drink driving is performed when an individual drives a vehicle whilst over the legal BAC limit of 0.05 and 0.00 for Provisional drivers. It can be performed

Discussion and Interpretation of Results The addition of HBr to 1-hexene created a 2-bromohexane‚ as indicated from the ethanol silver nitrate test and sodium iodide/acetone test. The observations when the product was subjected to these tests were similar to what were observed with the 2° bromide compound. When subjected to the silver nitrate test‚ the product produced a precipitate at the same rate of the 2° bromide compound‚ and the product produced a hue of yellow that was also similar to the
