Abstract
This invention relates to organic catalysts comprising iminium or oxaziridinium moieties, cleaning compositions comprising such catalysts; and processes for making and suing such catalysts and cleaning products.
Claims25
An organic catalyst having the following formula:
- 8
- wherein:
- R1 is a aryl or heteroaryl group that can be substituted or unsubstituted;
- R2 is a substituted or unsubstituted alkyl;
- R1 and R2 when taken together with the iminium form a ring
- R3 is a C1 to C20 substituted alkyl;
- R4 is the moiety Qt—A
- wherein:
- Q is a branched or unbranched alkylene
- t=0 or 1 and
- A is an anionic group selected from the group consisting of SO3O−, SO3−, CO2−, OCO2−, OPO32−, OPO3H− and OPO2−;
- R5 is the moiety —CR11R12—X—Gb—Xc—[(CR9R10)y—O]k—R8
- wherein:
- each X is independently selected from the group consisting of O, S, N—H, or N—R8;
- and
- each R8 is independently selected from the group consisting of alkyl, aryl and heteroaryl, said R8 moieties being substituted or unsubstituted, and whether substituted or unsubsituted said R8 moieties having less than 21 carbons;
- each G is independently selected from the group consisting of CO, SO2, SO, PO and PO2;
- R9 and R10 are independently selected from the group consisting of H and C1-C4 alkyl;
- and
- R11 and R12 are independently selected from the group consisting of H and alkyl, or when taken together may join to form a carbonyl;
- and
- b=0 or 1;
- c can=0 or 1, but c must=0 if b=0;
- y is an integer from 1 to 6;
- k is an integer from 0 to 20;
- and
- R6 is H, or an alkyl, aryl or heteroaryl moiety;
- said moieties being substituted or unsubstituted.
