The invention relates to compounds of formula (I), prepared by quaternising a compound (II) by means of at least one compound R
3
—X
⊖
:
R
1
=H or —CH
3
; R
2
=—CH
3
; —C
2
H
5
; —C
3
H
7
or —C
4
H
9
; and compound (I) is optionally quaternised on one of the nitrogens, which is symbolised by the fact that the R
3
, X
⊖
and ⊕ associated with this nitrogen are shown between brackets; if compound (I) is quaternised on a single nitrogen, R
3
and X
⊖
have the following meanings: (1) R
3
=—CH
3
or —CH
2
C
6
H
5
; and X
⊖
=Cl
⊖
or CH
3
OSO
3
⊖
; or (2) R
3
=a C
1
-C
12
-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 R
3
may be the same, in which case: (3) R
3
=a C
5
-C
12
alkyl group; and X
⊖
=CH
3
OSO
3
⊖
, Br
⊖
or I
⊖
; or different, in which case: (4) one of the R
3
=—CH
3
or —CH

; and X
⊖
=Cl

=Br
⊖
or I
⊖
.
该发明涉及公式(I)的化合物,通过用至少一种化合物R3—X⊖对化合物(II)进行季
铵化制备:
R1=H或—
CH3;R2=— ;—
C2H5;—
C3H7或—
C4H9;化合物(I)在其中一个氮上进行可选的季
铵化,这表明与该氮相关的R3、X⊖和⊕在括号之间显示;如果化合物(I)在单个氮上进行季
铵化,R3和X⊖具有以下含义:(1)R3=— 或—CH2C6H5;X⊖=Cl⊖或 OSO3⊖;或(2)R3=一种C1-C12烷基基团;X⊖=Br⊖或I⊖;如果化合物(I)在两个氮上进行季
铵化,两个X⊖可以相同也可以不同,两个R3可以相同,此时:(3)R3=一种C5-C12烷基基团;X⊖= OSO3⊖、Br⊖或I⊖;或不同,此时:(4)其中一个R3=— 或—CH2C6H5;X⊖=Cl⊖或 OSO3⊖;另一个=一种C5-C12烷基基团;X⊖=Br⊖或I⊖。
