PILOT PLANT PREPARATION OF DIBORANE.
Abstract
A pilot plant comprising three independent production units was constructed for the preparation of diborane according to the following equation: 3(LiBH4) + (BF3) (C2H5)2(O) = (Ether) 2(B2H6) + 3(LiF) + (C2H5)2(O). 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)
