Combustion Of Alcohols Planning This investigation involves burning alcohol in the air. Key science- Chemistry by Eileen Ramsden says that " an alcohol is a series of organic‚ homologous compounds‚ with the general formula Cn H2n+1OH". The alcohol reacts with the oxygen in the air to form the products water and carbon dioxide: Cn H2n+1OH +(n+n/2)-1O2 ? nH2O + nCO2 The structure of the molecules in this reaction is: H H | | H - C - C - O- H + 3[O=O] ? 1/2[O=C=O] + 3[H-O-H] | | H H This reaction

realize the influence of different parameters on SAGD. The effects of parameters such as horizontal well length‚ steam quality‚ viscosity‚ porosity‚ permeability in both horizontal and vertical directions‚ injection well location‚ injection rate‚ shale barrier and grid refinement on proficiency of SAGD are analysed. The following findings were obtained: Higher viscosity. | Higher CSOR ate earlier times. | Same permeability with one having low porosity. | Better recovery factor. | Injector well

polymerization from its terminal methacrylate groups. Since this structure has hydroxyl groups near the benzene ring‚ this polymer is considered to have high viscosity. Since high viscosity will affect the rigid structure after polymerization‚ a compound‚ typically triethyleneglycol dimethacrylate‚ or TEGDMA‚ is added to reduce the viscosity. Another disadvantage of using bis-GMA is that it absorbs light‚ which could possibly lead to color changes. Knowing this‚ the compound‚ 2-hydroxy-4-methoxy benzophenone

Synthesis of Methyl Stearate The purpose of this lab was the convert liquid methyl oleate to solid methyl stearate by catalytic hydrogenation. Firstly‚ we produced hydrogen gas using solid mossy zinc and sulfuric acid. Using the hydrogen produced in the previous reaction‚ we were able to convert the liquid methyl oleate to solid crystals of methyl stearate. A mineral oil was also used to bubbler was used to maintain the hydrogen pressure slightly above the atmospheric pressure and to prevent back-diffusion

for two types of fuels (methanol and ethanol) unlike the professional report which showed results for many types of fuels including biogas‚ LPG‚ kerosene and wood. This might mean that the reports would not be able to be compared as easily making them less useful. The professional report would be more useful for general fuel efficiency as it is more detailed whereas mine would be more useful if only information about the efficiency of methanol and ethanol was needed. Both of the reports
