Abstract

This method for producing stable dimethylamineboran comprises processing unstable dimethylamineboran in two steps, with water and at a temperature which is higher than the dimethylamineborane melting point but lower than that of its chemical dissolution. In the first step, the water is fed in an amount sufficient for chemically dissolving the active impurities in the dimethylamineboran and for forming from said impurities gaseous and solid reaction products which are further discharged. In the second step, the water is fed in an amount sufficient for physically dissolving the impurities that remain in the dimethylamineboran after the first step, wherein said dimethylamineboran is further stored in a non-dissolved state.

This method is concluded in that an unstable alarm will allow vacuum distillation. In doing so, they remove excess dimethylamine from the WB, which is the main impurity contaminating the target product. After removing the impurity, the DBD in the liquid state is discharged from the process and stored in a temperature monitor and at a constant temperature, where it is disposed of. After a vacuum distillation, a stable DRB is obtained, which has a long white needle pattern and a melting point
