Experimental Utilization Of 2 Ethoxy Ethyl Acetate

1404 words - 6 pages

Introduction
The diesel engine dominates the field of commercial transportation and agricultural machinery on account of its superior fuel efficiency. However they emit more emissions. The use of oxygenated fuels seems to be a promising solution towards reducing emissions in existing and future diesel engines. Oxygenated fuel is a chemical compound containing oxygen. It is used to help fuel burn more efficiently and cut down on some types of atmospheric pollution. Oxygenated fuels are characterized by the following molecular conditions of the fuels: molecular weights are low and the molecules have high hydrogen to carbon ratios and a low number of carbon to carbon bonds which lower the formation of solid carbon particulates, molecules contain oxygen which suppress the formation of soot, molecular bonds break up to radicals at reasonable activation energy which leads to high cetane numbers. The oxygenated blends usually enhance the combustion efficiency, burn rates and the ability to burn more fuel and these blends offer the reduction of exhaust emissions. Oxygenate utilization to produce "cleaner burning" diesel fuels has been known for over fifty years. Oxygenates are well known to reduce particulate emissions. Low molecular weight alcohols, such as methanol, ethanol, and t-butyl alcohol, have been reported to reduce emissions. Higher alcohols, carbonates, diethers, such as diglyme, and various glycol ethers have also been reported. Particularly attractive are P-series glycol ethers, which contain both ether and a propylene glycol end-group. This paper deals with 2-Ethoxy Ethyl Acetate criterion and emmision reductions in modern diesel engine. Various application strategies to reduce emissions and enhance diesel fuel performance are discussed. Diesel engine exhaust emissions (commonly known as 'diesel fumes') are a mixture of gases, vapours, liquid aerosols, and substances made up of particles.
Experimental Setup
The test rig facility used in the experimentation is developed at GGS College of Modern Technology, Kharar. It consists of CI engine of 5 HP rated power, a single-cylinder, 4-Stroke, water-cooled engine. An electrical dynamometer was used for loading the engine; a 5 KW generator was attached to the engine. A digital tachometer was used to measure the speed of the engine. The exhaust gas temperature was measured by a K-type thermocouple. The concentrations of NOx, HC and CO were measured by an exhaust gas analyzer. The output power of the engine was calculated based on the data of the engine torque and speed, while the brake thermal efficiency was obtained by using the data of the engine output power and the data of the fuel consumption measured by using burette.

Lab report on a fischer esterfication

868 words - 3 pages temperature was too high in heating the mixture, reflux would not occur. That is to say the solvent would not boil and then recondense in the reflux condenser. This would cause more the ethyl acetate to boil out as it forms. Third, if the starting material or finished product were spilled when being weighed the percent yield would be incorrect.To get better results in this experiment would simply be to do as many trials as it takes until the results show a higher percent yield. By doing this one could lower the error percentage and see what the actual amount of Hexyl acetate that can be produced if one was shooting for high yield.
