Procedure

Following the procedure of Example 5, but substitute ammoniumpentaborate with 5.82 g (0.02 mole) borax pentahydrate and using 3.08 g (0.0126 mole) bariumchloride in a total of 33 ml boiling water (1 hr), 4.1 g bariumtetraborate was isolated. The analysis for BaB4O7.4 H2O showed a B/Ba ratio of 4.01:1. IR spectrum showed λmaxKBr 3400 (broad), 1640 (medium), 1420 (shoulder), 1340 (broad, very strong), 1000 (broad, very strong), 730 (weak), 690 (weak) cm- 1.
