Abstract
NaBH4 is prepared by reacting B2H6 and NaH in a compound of formula RO(CH2.CH2O)nR1 where R and R1 are alkyl radicals containing 1-4 C atoms and n is an integer from 1-4, at 35-75 DEG C. The ethers include diethyl, dimethyl, and di-n-butyl ethers of ethylene glycol, and of di-, tri-, and tetra-ethylene glycols, and should contain 1-10% NaH. The ether solution of NaBH4 may be reacted with BCl3 at 40-47 DEG C. to form B2H6.
