ABSTRACT:
The invention relates to compounds of formula (I), prepared by quaternising a compound (II) by means of at least one compound R3—X⊖:R1=H or —CH3; R2=—CH3; —C2H5; —C3H7or —C4H9; and compound (I) is optionally quaternised on one of the nitrogens, which is symbolised by the fact that the R3, X⊖and ⊕ associated with this nitrogen are shown between brackets; if compound (I) is quaternised on a single nitrogen, R3and X⊖have the following meanings: (1) R3=—CH3or —CH2C6H5; and X⊖=Cl⊖or CH3OSO3⊖; or (2) R3=a C1-C12-alkyl group; and X⊖=Br⊖or I⊖; if compound (I) is quaternised on both nitrogens, the two X⊖may be the same or different and the two R3may be the same, in which case: (3) R3=a C5-C12alkyl group; and X⊖=CH3OSO3⊖, Br⊖or I⊖; or different, in which case: (4) one of the R3=—CH3or —CH2C6H5; and X⊖=Cl⊖or CH3OSO3⊖; and the other=a C5-C12-alkyl group; and X⊖=Br⊖or I⊖.
