The oxidation of primary alcohol to aldehyde by the homogeneous catalyst is an added advantage due to mild reaction condition and simplified downstream processing. The reaction normally carried out at low temperature in the organic media with the presence of co-catalyst, base and excess amount of pure oxygen. However, the process is susceptible to overoxidation which leads to the formation of carboxylic acid. RCH2OHk1DCHOk2RCOOH b] Recently, an investigation has been carried out on the conversion of a long chain of primary alcohol (CAo=2mol/L ) to aldehyde in a tubular reactor. It has been found that the oxidation of alcohol to aldehyde and carboxylic acid follows the first order of reaction with k1=0.008/s and k2=0.002/s : The initial concentration of the primary alcohol is 0.2mol/L with inlet volumetric flow rate of 0.05L/s. [i] Find the conversion of alcohol at space-time, =400s. [6 marks] [ii] Determine the space-time and volume of the reactor where the concentration of aldehyde is at the optimum level
