be188 hcp d400 d400 were changed to 1 0 3 0 7 and 1 0 7 0 3 respectively repeat step 2 of example 1 except that hcp d400 was not added so that the equivalent ratio of be188 hcp d400 d400 was 1 0 1 tetrahydrofuran thf 40 g and d400 10 g 25 mmole were added in a three necked bottle and uniformly mixed hcp 7 24 g 4 2 mmole 20 wt in thf was slowly dropped into the above solution next tea 3 79 g was slowly dropped into the three necked bottle so that the mole ratio of hcp d400 tea was 1 6 9 the solution became white from transparency the reaction was performed in nitrogen gas and controlled at 50 u00b0 c after 24 hours the resultant salt was filtered with a filter paper and thf was removed by decompression rotary concentration to obtain the final product hcp d400 water was added into a beaker containing na mmt 1 g 1 2 meq to have a whole mass 100 g the solution was then swollen at 80 u00b0 c for 1 hour hcp d400 2 61 g 3 6 meq from step 1 was mixed with hcl aq 0 125 g 1 2 meq at an equivalent ratio h u2014 nh 2.
