Preparation of alkylidene-bis-haloalkanoic amides

Claim 1

THE METHOD OF PREPARING ALKYLIDENE-BIS-HALOALKYL AMIDES WHICH COMPRISES VAPORIZING AN UNSATURATED NITRILE OF THE CLASS CONSISTING OF LOWER ALKENYL AND CHLORO-LOWER ALKENYL NITRILES, CONTACTING SAID NITRILE WHILE IN THE VAPOR PHASE WITH THE VAPOR OF A LOWER ALKANAL, VAPOR OF THE GROUP CONSISTING OF HYDROGEN CHLORIDE AND HYDROGEN BROMIDE, AND WATER VAPOR, AT A TEMPERATURE FROM ABOUT 80* C. TO 500* C., IN THE PRESENCE OF A CATALYST SELECTED FROM THE CLASS CONSISTING OF ALUMINUM CHLORIDE, ALUMINUM OXIDE, BORON PHOSPHATE, ZINC OXIDE, CLAY SHARD, SILICA GEL, AND MIXTURES THEREOF, THE MOLAR AMOUNT OF ALKANAL RANGING FROM ABOUT 0.5 TO 3 TIMES THE MOLAR AMOUNT OF NITRILE, THE MOLAR PROPORTION OF HYDROGEN HALIDE BEING AT LEAST 1 MOL RELATIVE TO EACH MOL OF THE NITRILE, THE QUANTITY OF WATER BEING FROM TWO TO THREE TIMES THE QUANTITY OF ALKANAL, AND COLLECTING THE BIS-AMIDE.

Claim 2

THE METHOD OF PREPARING ALKYLIDENE-BIS-HALOALKYL AMIDES WHICH COMPRISES VAPORIZING AN UNSATURATED NITRILE OF THE CLASS CONSISTING OF LOWER ALKENYL AND CHLORO-LOWER ALKENYL NITRILES, CONTACTING SAID NITRILE WHILE IN THE VAPOR PHASE WITH THE VAPOR OF A LOWER ALKANAL, VAPOR OF THE GROUP CONSISTING OF HYDROGEN CHLORIDE AND HYDROGEN BROMIDE, AND WATER VAPOR, AT A TEMPERATURE FROM ABOUT 80* C. TO 500* C., IN THE PRESENCE OF A CATALYST SELECTED FROM THE CLASS CONSISTING OF ALUMINUM CHLORIDE, ALUMINUM OXIDE, BORON PHOSPHATE, ZINC OXIDE, CLAY SHARD, SILICA GEL, AND MIXTURES THEREOF, THE MOLAR AMOUNT OF ALKANAL RANGING FROM ABOUT 0.5 TO 3 TIMES THE MOLAR AMOUNT OF NITRILE, THE MOLAR PROPORTION OF HYDROGEN HALIDE BEING AT LEAST 1 MOL RELATIVE TO EACH MOL OF THE NITRILE, THE QUANTITY OF WATER BEING FROM TWO TO THREE TIMES THE QUANTITY OF ALKANAL, AND COLLECTING THE BIS-AMIDE.
