More Information
Summary:The invention comprises compounds of general formula <FORM:1000526/C2/1> in which R1 is alkyl (1-4 C), chloroalkyl (1-4 C) or phenyl which may have a chloro or nitro substituent, R2, R3 and R4 are hydrogen alkyl (1-4 C) or aryl (6-10 C), or R2 together with R3 or R4 may form a saturated ring having 5-7 ring members, or R3 and R4 may form a ring having 5-6 ring members and optionally in addition an oxygen atom; and their preparation by reacting a compound ClCH2.R1.N-CO-Cl with a compound R2-CO-N.R3.R4 at 0 DEG to 150 DEG C. Specification 946,397 is referred to.ALSO:Disinfectant compositions comprise aqueous solutions of chloromethylamidinium salts of general formula <FORM:1000526/A5-A6/1> in which R1 is alkyl, chloroalkyl (1-4C) or phenyl which may have a chloro or nitro substituent, R2, R3 and R4 are hydrogen, alkyl (1-4C) or aryl (6-10C), or R2 together with R3 or R4 may form a saturated ring having 5-7 ring members, or R3 and R4 may form a ring having 5-6 members and optionally in addition an oxygen atom. 0.5-5% solutions for dipping or spraying are mentioned. Specification 946,397 is referred to.
