Estimating the term…
Bleaching compositions are provided that comprise a nitrile containing compound that has the nitrile bonded to a quaternary nitrogen through a methylene unit (where one or both of the normal hydrogens can be substituted), and two of the quaternary nitrogen bonds are part of a saturated ring. This saturated ring contains from two to eight atoms in addition to the quaternary nitrogen. A source of active oxygen will react with the nitrile for bleaching applications. Particularly preferred nitrile containing compounds are N-alkyl morpholinium acetonitrile salts.
A compound having the structure of Formula IA ##STR11## wherein A is a saturated ring formed by a plurality of atoms in addition to the N.sub.1 atom, the saturated ring atoms to include at least one carbon atom and at least one heteroatom in addition to the N.sub.1 atom, the said one heteroatom selected from the group consisting of O, S and N atoms, the substituent R.sub.1 bound to the N.sub.1 atom of the Formula IA structure is (a) a C.sub.1-8 alkyl or alkoxylated alkyl where the alkoxy is C.sub.2-4, (b) a C.sub.4-24 cycloalkyl, (c) a C.sub.7-24 alkaryl, (d) a repeating or nonrepeating alkoxy or alkoxylated alcohol, where the alkoxy unit is C.sub.2-4, or (e) --CR.sub.5 R.sub.6 C.tbd.N where R.sub.5 and R.sub.6 are each H, a C.sub.1-24 alkyl, cycloalkyl, or alkaryl, or a repeating or nonrepeating alkoxyl or alkoxylated alcohol where the alkoxy unit is C.sub.2-4, in Formula IA at least one of the R.sub.2 and R.sub.3 substituents is H and the other of R.sub.2 and R.sub.3 is H, a C.sub.1-24 alkyl, cycloalkyl, or alkaryl, or a repeating or nonrepeating alkoxyl or alkoxylated alcohol where the alkoxy unit is C.sub.2-4, and Y is at least one counterion.
A compound having the structure of Formula IA ##STR12## wherein A is a saturated ring formed by a plurality of atoms in addition to the N.sub.1 atom, the saturated ring atoms to include at least one carbon atom and at least one heteroatom in addition to the N.sub.1 atom, the said one heteroatom selected from the group consisting of O, S and N atoms, the substituent R.sub.1 bound to the N.sub.1 atom of the Formula IA structure is (a) a C.sub.1-8 alkyl or alkoxylated alkyl where the alkoxy is C.sub.2-4, (b) a C.sub.4-24 cycloalkyl, (c) a C.sub.7-24 alkaryl, (d) a repeating or nonrepeating alkoxy or alkoxylated alcohol, where the alkoxy unit is C.sub.2-4, or (e) --CR.sub.5 R.sub.6 C.tbd.N where R.sub.5 and R.sub.6 are each H, a C.sub.1-24 alkyl, cycloalkyl, or alkaryl, or a repeating or nonrepeating alkoxyl or alkoxylated alcohol where the alkoxy unit is C.sub.2-4, at least one of the R.sub.2 and R.sub.3 is H, and the other of R.sub.2 and R.sub.3 is H, a C.sub.1-24 alkyl, cycloalkyl, or alkaryl, or a repeating or nonrepeating alkoxyl or alkoxylated alcohol where the alkoxy unit is C.sub.2-4, and Y is at least one counterion selected from the group consisting of bromide, nitrate, and alkyl sulfate.
