Abstract
This present invention provides materials for use as solid or concentrated chemical precursors for the production of organic peroxy acids (peracids). Organic peroxy acids are formed using a precursor according to the invention when they are combined with hydrogen peroxide or a hydrogen peroxide precursor such as a percarbonate or a perborate in aqueous medium. Organic peroxy acids, such as peroxyacetic acid, are used currently to disinfect medical equipment such as endoscopes and related items.
Claims62
1) A composition of matter useful for forming organic peroxy acids, which comprises a polyamino compound having the structure:
- 53
- in which L is a divalent radical that is independently selected from the group consisting of:
- 54
- and wherein R1, R2, R3, and R4 are each independently selected from the group consisting of:
- hydrogen, any C1 to C20 hydrocarbyl group, and the group:
- 55
- subject to the proviso that:
- at least one of R1, R2, R3, and R4 are the group:
- 56
- in which R5 is in each occurrence independently hydrogen or any C1 to C20 hydrocarbyl group.
28) A process for disinfecting a surface comprising the steps of contacting said surface with an aqueous composition that is formed from mixing:
- a) water;
- b) a composition of matter which comprises an amino compound having the structure:
- 68
- in which L is a divalent radical that is independently selected from the group consisting of:
- 69
- and wherein R1, R2, R3, and R4 are each independently selected from the group consisting of:
- hydrogen, any C1 to C20 hydrocarbyl group, and the group:
- 70
- subject to the proviso that:
- at least one of R1, R2, R3, and R4 are the group:
- 71
- in which R5 is independently in each occurrence hydrogen or any C1 to C20 hydrocarbyl group;
- and
- c) a source of peroxide.
41) A process according to claim 41 wherein said source of peroxide is a solid compound which upon being contacted with water yields a peroxide.
48) A process for volatilizing a peroxy acid which comprises mixing:
- a) water;
- b) a composition of matter which comprises an amino compound having the structure:
- 83
- in which L is a divalent radical that is independently selected from the group consisting of:
- 84
- and wherein R1, R2, R3, and R4 are each independently selected from the group consisting of:
- hydrogen, any C1 to C20 hydrocarbyl group, and the group:
- 85
- subject to the proviso that:
- at least one of R1, R2, R3, and R4 are the group:
- 86
- in which R5 is in each occurrence independently hydrogen or any C1 to C20 hydrocarbyl group;
- and
- c) a source of peroxide,
- under conditions sufficient to enable evolution of vapors of peroxy acid from the aqueous solution so formed.
