Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
124 words
A METHOD FOR MANUFACTURING SUBSTITUTED AMIDES FROM PROTEINACEOUS MATERIALS, COMPRISING: HEATING AND REACTING AN AMINE-SUPPLYING COMPOSITION HAVING AT LEAST ONE ACYLATABLE AMINO HYDROGEN AND SELECTED FROM THE GROUP CONSISTING OF WATER-SOLUBLE ALIPHATIC ALKYLOLAMINES AND WATER-SOLUBLE ALIPHATIC POLYAMINES WITH A PROTEINACEOUS COMPOSITION HAVING MORE THAN ONE PEPTIDE GROUP UNDER CONDITIONS SUCH THAT THERE IS PRESENT DURING THE AMIDATING REACTION LESS THAN 20% WATER BASED ON THE WEIGHT OF SAID PROTEINACEOUS COMPOSITION, SAID REACTION BEING CARRIED OUT BY HEATING THE REACTION MIXTURE AT A TEMPERATURE SUFFICIENT TO REMOVE WATER FROM THE SYSTEM, SAID HEATING BEING CONDUCTED UNTIL AN ALIQUOT PART OF THE REACTION PRODUCT IS SOLUBLE IN DILUTE AQUEOUS ACID WHEREBY WATER-SOLUBLE AMIDES OF THE CONSTITUENT AMINO ACIDS AND POLYPEPTIDES OF SAID PROTEINACEOUS MATERIALS ARE FORMED.
