6. Two chemical processes are presented below. Compare and contrast the enviromental impacts of each of these processes using the green chemistry tenets discussed in class. NaCN CEN H20 .80, (eat)REACTION A H20-solvent 0.15 mol% O C-OH CO (gas): 0.05 mol % Pd\", R REACTION B NaOH-H20
Solution
First point, Reaction A is two step reactRea while reaction B is one step reaction. According to green chemistry, atom economy should be there, more number of steps lesser atom economy. So reaction B is more acceptable.
Second point, In Reaction A, all compounds and reagent are easily available and easily to handlle while in reaction B phenylphosphine sulfate is required with palladium. ( Transition metal are not green reagent while difficult to handle phosphine compound. Green chemistry principle to use benign chemicals.
Third point, you have not mentioned about the amount of quaternary ammonium salt does it require in stoichoimetric ratio or catalytic amount. If it is in stoichoimetric then it is not catalyst because in green chemistry principle, catalyst should be use in catalytic amount. In Reaction B catalyst used in catalytic amount.
Fourth point, you have not mentioned about the temperature, pressure and yield of product. Reaction should be energy efficient for green chemistry principle.
