that of 228 nm for one of the degraded pq1 molecules it is likely that all pq1 will eventually be degraded in to the small molecules during reaction or storage if the time is long enough in order to prevent the side end capping reaction and increase the main end capping reaction rate the amount of tea in the admixture of the reactants was increased table 2 shows the proton nmr spectrum data for pq1 synthesized at 65 u00b0 c with admixture of 1 mole of 1 4 bis dimethylamino 2 butene 0 9 moles of tea and 1 15 moles of 1 4 dichlo butene the molar ratio of 1 4 bis dimethylamino 2 butene with tea is 1 11 1 instead of 5 1 as in example 1 above the far right column of table 2 lists the end capping percentage over the reaction time it can be seen that even at the presence of large excess amount of tea the reaction is still not complete until a time of 4 hours see fig1 and 2 10 14 grams 71 3 mmoles of 1 4 bis dimethylamino 2 butene 6 4 grams 42 8 mmoles of tea 4 92 ml of 6n hcl 29 5 mmoles 18 8 grams of water and a stir bar were combined in a 100 ml three mouth flask the flask was submerged.
