in the following various embodiments 1 a 2 a and 3 a first 100 ml sized two neck round bottom flask is used to add 1 82 gm 0 01 mole of 7 8 acenaphthrenequinone 2 37 gm 0 03 mole of ammonium bicarbonate 1 45 gm 0 011 mole of acetyaldehyde and 30 ml of acetic acid under nitrogen then heat stir and recirculate for 12 hours under 100 u00b0 c and then hold still until it cools back down to room temperature it may have a faint yellow solid to separate out and thus filter out a solid from the reactive liquid finally after vacuum drying is used to dry out the solid a compound a of 1 96 gm 9 5 mmole crystallizes out the absorption rate is 95 percent the reactive formula is represented by the following formula ii after that take 1 50 gm of compound a 7 3 mmole to add 0 21 gm 8 8 mmole of sodium hydride into 30 ml of tetrahydrofuran and then stir under room temperature for 2 hours then add 1 25 gm 8 8 mmole of methyl iodide and then heat and recirculates for 6 hours then hold it still until it cools back down to room temperature finally after vacuum drying is used to dry out the solid a compound b of 1 52 gm 6 9 mmole crystallizes out the absorption rate is.
