Ethyl acetate containing trace amounts of ethanol reacts in the presence of sodium
Ethyl acetate (ethyl acetate sds), also known as ethyl acetate, is an important and widely used chemical in industry. It has an important role as a solvent in adhesives, paints or coatings and can be used to replace aromatic solvents such as toluene (Appel et al., 2011; Nguyen et al., 2010). In addition, ethyl acetate exhibits similar physicochemical properties to some previously discussed chemicals that may show potential as a diesel additive (Ashok, 2010). In this study, compression combustion (CI) diesel engines ran on a mixture containing ethanol and conventional diesel. Ethyl acetate is added to the mixture and acts as a surfactant. The results showed that significant reductions in environmentally harmful emissions of particulate matter, smoke density, hydrocarbons and carbon monoxide were observed.
In fact, there are several alternatives to ethyl acetate production techniques. Traditionally, ethyl acetate has been produced from fossil resources, but in terms of sustainability, recent research efforts have focused on investigating the possibility of a simple and economical one-pot synthesis strategy utilizing bioethanol.
Ethyl acetate containing trace amounts of ethanol reacts in the presence of sodium to form a self-condensation product, a sodium derivative of ethyl acetoacetate, which is carefully acidified to form a free n-keto ester. The entire reaction, often referred to as Claisen ester condensation, essentially eliminates one ethanol molecule from two ethyl acetate molecules.
Ethyl acetate forms hydrogen bonds with silanol groups separated on silicon dioxide, producing infrared bands at 3440 and 1712 cm−1, which are attributed to tensile vibrations that perturb silanol and carbonyl groups, respectively (Figure 5B-F). The band at 1747 cm−1 is caused by the carbonyl stretching vibration of ethyl acetate in solution. The spectrum of preheated silica at 453 K contains bands at 3660 and 3550 cm-1, which may be attributed to the two types of adjacent interacting surface hydroxyl groups (Cross and Rochester, 1979; Rochester and Trebilco, 1979).
