摘要：
UREIDOPROPIONIC ACIDS OF THE FORMULA:
R1-N(-R2)-CO-N(-R3)-CH2-C(-R4)(-R5)-COOH
WHEREIN R1 TO R5 DENOTE IDENTICAL OR DIFFERENT ALIPHATIC, CYCLOALIPHATIC, ARALIPHATIC OR AROMATIC RADICALS, SAID UREIDOPROPIONIC ACIDS BEING PREPARED BY REACTING A UREIDOPROPIONALDEHYDE HAVING THE FORMULA:
R6-N(-R2)-CO-N(-R3)-CH2-C(-R4)(-R5)-CHO
WITH AN OXIDIZING AGENT AT A TEMPERATURE OF FROM 0* TO 100*C., SAID ACIDS BEING USEFUL AS PAPER FINISHING AGENTS AND AS STARTING MATERIALS FOR THE PRODUCTION OF PAPER FINISHING AGENTS AND HERBICIDES.
