1353843 Aminotriazine derivatives CHEMIELINZ AG 3 Feb 1972 [5 Feb 1971] 5186/72 Heading C2C Aminotriazine derivatives of formula in which R represents an optionally branched alkyl group or alkenyl group (up to 6C), and R1 represents an optionally branched alkyl group (up to 6C) and X is a hydrogen atom or an amino group, an alkyl group (up to 4C), a phenyl group or the group by reacting an aminotriazine derivative in which Y is a hydrogen atom, an alkyl group (up to 4C) or an amino group and R11 is a hydrogen atom or the group with at least one R11 being hydrogen if Y is other than an amino group, with at least 0À5 mol. excess of an aldehyde and with at least 1 mol. excess of a primary or secondary saturated or unsaturated alcohol R.OH, at between 50‹ C. and the boiling point of the mixture, in the presence of an inorganic or organic acid as the catalyst. The ether groups may be trans-etherified by a further alcohol in the presence of an acid catalyst. Melamine or alkylated or phenylated guanamines may be used and the alcohol may also serve as solvent. Catalysts may be p-toluene sulphonic acid and sulphamic acid. Examples describe the preparation of N,N1-bis-iso-butylol-melamihe-methyl, -ethyl, -propyl, -isopropyl, -n-butyl, -isobutyl, -isoamyl, -alkyl ethers, N,N1-bis-propylolmelamine - isobutyl ether, N,N1,N11 - tris - isobutylolmelamine - methyl and isobutyl ether, N,N1,N11 - tris - n - butylolmelamine - methyl, - ethyl, and -isobutyl ether, N,N1,N11-trispropylolmelamine - methyl - ether, N,N1,N11- trisethylolmelamine - methyl ether and N,N1- bis - (1 - methoxyisobutylamino) - 6 - methyl - striazine.
