Notes for class 11 Physics, Chemistry As shown by the atom economy this reaction has high atom efficiency: mass of atoms in desired productmass of atoms in reactants=8888=100%(to3sf). An assessment of different intensified processes for the production of ethyl acetate through Fisher esterification has been carried out. In the production of ethyl acetate via ethanol dehydrogenation there are some safety concerns that rise, such as the huge amount of pure hydrogen that is produced as a by-product. The aldol-Tishchenko reaction: A tool in stereoselective synthesis. The project economic analysis provided in the report discusses a Germany-based plant and encorporates: From $ USD The hydrogen gas produced can also be used as a carrier gas in the process (Santacesaria et al,2011). However as with esterification there is again the need to separate the catalyst from the product and there is generation of a large amount of spent catalyst and waste water due to using homogeneous catalysts. This restriction means that the available options for a location to build the plant are very limited and because these are less common in Europe due to Europe not being a large petrochemical producer and the fact that the ethyl acetate produced is required specifically for the European market means that that the only viable options would be to import from outside Europe or build the plant outside of Europe both of which would be very costly. Also, because this reaction does not tend to lead to formation of by-products which have boiling points close to that of ethyl acetate, recovery of substantially pure ethyl acetate from the esterification product mixture is usually not complicated by the presence of by-products (Colley et al, 2004). This alternative makes this process highly sustainable as opposed to other process routes which require fossil based feedstock.
