SYNTHESIS OF ESTERS USING GREEN AND NON-GREEN CHEMISTRY Abstract Esters are a class of organic compounds with the general formula RCOOR’. Ester also contributes the flavor and aromas in fruits and flowers. The esterification reactions will use in the procedure‚ which are the interaction of a carboxylic acid with an alcohol‚ aided by an inorganic acid catalyst (H2SO4). Moreover‚ the green method will not use any catalyst but using heating source instead (microwave). Based on the comparison of

IONIC COMPOUNDS In chemistry‚ an ionic compound is a chemical compound in which ions are held together in a lattice structure by ionic bonds. Usually‚ the positively charged portion consists of metal cations and the negatively charged portion is an anion or polyatomic ion. Ions in ionic compounds are held together by the electrostatic forcesbetween oppositely charged bodies. Ionic compounds have high melting and boiling points‚ and they are hard and very brittle. Ions can be single atoms‚ as the sodium and chlorine in

REDUCTION GEARBOX DESIGN PROJECT DESCRIPTION You are the designer and you have been asked to design a speed reducer that will take power from the shaft of an electric motor rotating at 1500 rpm and deliver it to a machine that is to operate at approximately 750 rpm. Assume that you have decided to use spur gears to transmit the power and you are proposing to use a single-reduction speed reducer. The power to be transmitted by the shaft is 20 KW and the input shaft is coupled to
