Abstract:

A pilot plant comprising three independent production units was constructed for the preparation of diborane according to the following equation 3LiBH4 BF3 C2H52O Ether 2B2H6 3LiF C2H52O. A total of 4.2 Kg of diborane of about 95 percent purity was prepared in forty-seven runs with an over-all yield of 90.9 percent based on the lithium borohydride. A production unit was essentially all glass and consisted of a reactor connected to suitable cold traps for purification and transfer of the product. The reaction was carried out under an inert atmosphere and transfers to storage bombs were made at reduced pressure. Author
