METHOD FOR PRODUCTION OF POLYGUANIDINE SALT Russian patent published in 2008 - IPC C07C279/02 A61L2/16

Abstract RU 2318803 C1

FIELD: medicine, veterinary, waste treatment, biocide preparations.

SUBSTANCE: claimed method includes premixing of diamine and guanidine salt in reactor and gradual heating of obtained mixture. At optimal temperature of 180-220°C reaction of polycondensation is carried out in melt with simultaneous melt decompressing at Prest = 0.05-0.2 atm for 4-6 hours up to total ammonia and diamine rest elimination. Further melt is fed into cooling form and ground in dry atmosphere.

EFFECT: simplified technology, decreased impurity content.

3 cl, 1 tbl, 7 ex, 1 dwg
