    摘要： THE INVENTION RELATES TO THE PREPARATION OF POTASSIUM CYANOBOROHYDRIDE. THIS COMPOUND IS PREPARED BY MIXING SUBSTANTIALLY ANHYDROUS HYDROGEN CYANIDE WITH A SUBSTANTIALLY ANHYDROUS POTASSIUM BOROHYDRIDE AT A TEMPERATURE BETWEEN 0*C. AND 100*C. IN SUBSTANTIALLY ANHYDROUS DIMETHYLFORMAMIDE AT ATMOSPHERIC PRESSURE. IF DESIRED TO AVOID LOSS OF HYDROGEN CYANIDE, A PRESSURE OF FROM ABOUT 1 TO 5 POUNDS PER SQUARE INCH MAY BE USED. PREFERABLY, THE PREPARATION IS CARRIED OUT IN TWO STAGES (1) INITIALLY AT A TEMPERATURE BETWEEN ABOUT 10*C. TO ABOUT 35*C. UNTIL SUBSTANTIALLY ALL HYDROGEN HAS CEASED TO BE EVOLVED, AND (2) THEN AT A TEMPERATURE BETWEEN ABOUT 35*C. AND THE BOILING POINT OF THE SOLVENT UNTIL ALL THE INTERMEDIATE PRODUCTS HAVE BEEN CONVERTED TO THE DESIRED CYANOBOROHYDRIDE.

    摘要： THE INVENTION RELATES TO THE PREPARATION OF LITHIUM, SODIUM AND QUATERNARY AMMONIUM CYUANOBROHYDRIDES. THESE COMPOUNDS ARE PREPARED BY MIXING SUBSTANTIALLY ANHYDROUS HYDROGEN CYANIDE WITH A SUBSTANTIALLY ANHYDROUS LITHIUM OR SODIUM OR QUATERNARY AMMONIUM BOROHYDRIDE AT A TEMPERATURE BETWEEN 0*C. AND 100*C. IN A SUBSTANTIALLY ANHYDROUS SOLVENT, SUCH AS TETRAHYDROFURAN, GLYME, DIGLYME, TRIGLME OR DIMETHYL FORMAMIDE OR MIXTURES OF THESE AT ATOMPHERIC PRESSURE. IF DESIRED. TO AVOID LOSS OF HYDROGEN CYANIDE, A PRESSURE OF FROM ABOUT 1 TO 5 POUNDS PER SQUARE INCH MAY BE USED. PREFERABLY, THE PREPARATION IS CARRIED OUT IN TWO STAGES (1) INTIALLY AT A TEMPERATURE BETWEEN ABOUT 10*C. TO ABOUT 35*C. UNTIL SUBSTANTIALLY ALL HYDROGEN HAS CEASED TO BE EVOLVED AND (2) THEN AT A TEMPERATURE BETWEEN ABOUT 35* C. AND THE BOILING POINT OF THE SOLVENT UNTIL ALL THE INTERMEDIATE PRODUCTS HAVE BEEN CONVERTED TO THE DESIRED CYANOBOROHYDRIDE.
