TRIPHENYLBORANE is a severe eye irritant.
| [Purification Methods]
Recrystallise the borane three times from Et2O or *C6H6 under N2 and dry it at 130o. It can be distilled in a high vacuum at 300-350o and has been distilled (b 195-215o/~15mm) in vacuum using a bath temperature of 240-330o. N2 is introduced into the apparatus before dismantling. It forms complexes with amines. [Nielsen et al. Chem Ind (London) 1069 1957, Wittig et al. Justus Liebigs Ann Chem 563 110 1949, Bent & Dorfman J Am Chem Soc 57 1259 1935, Beilstein 16 IV 1623.] |
