USE OF SUBSTITUTED 2,4-BIS (ALKYLAMINO) PYRIMIDINES OR -QUINAZOLINES AS ANTIMICROBIALS.

摘要

The use of 2,4-bis(alkylamino)pyrimidines of formula (1) R1 is C1-C12alkyl or C6-C10laryl; R2 is hydrogen or C1-C12alkyl; or R1 and R2 together forma radical of formula (1 a) R' and R" are each independently of the other hydrogen, C1-C6alkyl or C1-C6alkoxy, R3 and R5 are each independently of the other hydrogen or C1-C8alkyl; R4 is C1-C20alkyl, unsubstituted phenyl, C6-C10aryl, C6-C10aryl-C1-C6alkyl, hydroxy-C1-C6alkyl, di-C1-C6al-kylamino-C1-C6aIkyl, mono-C1-C6alkylamino-C1-C6alkyl, -(CH2)2-(O-(CH2)2)1-4-OH or -(CH2)2-(O-(CH2)2)1-4-NH2; R6 is C1-C20alkyl, C6-C10aryl, C6-C10aryl-C1-C6alkyl, hydroxy-C1-C6alkyl, di-C1 -C6alkylamino-C1-C6alkyl, mono-C1-C6alkylamino-C1-C6alkyl, -(CH2)2-(O-(CH2)2)1-4-OH or -(CH2)2-(O-(CH2)2)1-4-NH2; or R3 and R4 and/or R5 and R6, together form a pyrrolidine, piperidine, hexamethyleneimine or morpholine ring; in the antimicrobial treatment of surfaces.
