Problems solved by technology

In short, despite the extensive literature on macrocycles and transition metal complexes, crosslinking bridged tetraaza- and pentaazamacrocycles appear to be relatively unreported and not explicitly derived from the extensive chemical literature. Identify these substances, either alone or in their transition metal complexes, used in bleaching detergents

Embodiment 1

[0228] Example 1 - [Mn(Bcyclam)Cl 2 ]Synthesis (a) Method 1

[0229] "Bcyclam" (5,12-dimethyl-1,5,8,12-tetraazabicyclo[6.6.2]hexadecane) was introduced by G.R.Weisman et al., in J.Amer.Chem .Soc.), (1990), 112,8604 described in the synthetic method to prepare. Dissolve Bcyclam (1.00 g, 3.93 mmol) in anhydrous CH 3 CN (35ml, from CaH 2 distilled). The solution was then evacuated at 15 mm pressure until CH 3 CN started to boil. The flask was then connected to atmospheric pressure Ar. This degassing step was repeated 4 times. Under Ar atmosphere, add the Mn (pyridine) synthesized according to the method in H.T.Witteveen et al. 2 Cl 2 (1.12 g, 3.93 mmol). The cloudy reaction solution slowly started to turn black. After stirring overnight at room temperature, the reaction solution turned dark brown with suspended fine particles. The reaction solution was filtered with a 0.2 μ filter. The filtrate was light brown. The filtrate was evaporated to dryness us...

Embodiment 2

[0230] Freshly distilled Bcyclam (25.00 g, 0.0984 mol) prepared by the same method as above was dissolved in anhydrous CH 3 CN (900ml, from CaH 2 distilled). The solution was then evacuated at 15 mm pressure until CH 3 CN started to boil. The flask was then connected to atmospheric pressure Ar. This degassing step was repeated 4 times. Under Ar atmosphere, add MnCl 2 (11.25 g, 0.0894 mol). The cloudy reaction solution immediately turned black. After stirring at reflux for 4 hours, the reaction solution became dark brown with suspended fine particles. The reaction solution was filtered through a 0.2 μ filter under dry conditions. The filtrate was light brown. The filtrate was evaporated to dryness using a rotary evaporator. The resulting tan solid was dried overnight at room temperature at 0.05 mm. The solid was suspended in toluene (100ml) and heated to reflux. The toluene was decanted and the procedure repeated with an additional 100 ml of toluene. The remaining ...

Embodiment 3

[0234] Will C 4 -Bcyclam (2.00g, 6.76mmol) suspended in anhydrous CH 3 CN (75ml, from CaH 2 distilled). The solution was then evacuated at 15 mm pressure until CH 3 CN started to boil. The flask was then connected to atmospheric pressure Ar. This degassing step was repeated 4 times. Under Ar atmosphere, add MnCl 2 (0.81 g, 6.43 mmol). The brown cloudy reaction solution turned black immediately. After stirring at reflux for 4 hours, the reaction solution became dark brown with suspended fine particles. The reaction solution was filtered through a 0.2 μm membrane filter under dry conditions. The filtrate was light brown. The filtrate was evaporated to dryness using a rotary evaporator. The resulting white solid was suspended in toluene (50ml) and heated to reflux. The toluene was decanted and the procedure repeated with an additional 100 ml of toluene. Remove the remaining toluene using a rotary evaporator. After drying overnight at room temperature at 0.05 mm, 2.4...

Abstract

Laundry or cleaning composition comprising: (a) an effective amount, preferably from about 0.0001 % to about 99.9 %, more typically from about 0.1 % to about 25 %, of a bleach activator and / or organic percarboxylic acid; (b) a catalytically effective amount, preferably from about 1 ppb to about 99.9 %, of a transition-metal bleach catalyst which is a complex of a transition-metal and a cross-bridged macropolycyclic ligand; and (c) at least about 0.1 % of one or more laundry or cleaning adjunct materials, preferably comprising an oxygen bleaching agent. Preferred compositions are laundry compositions and automatic dishwashing detergents which provide enhanced cleaning / bleaching benefits through the use of such catalysts in combination with bleach activators and / or organic percarboxylic acids.

Description

field of invention [0001] The present invention relates to detergent and detergent additive compositions and methods of their use. The composition comprises selected transition metals such as Mn, Fe or Cr with selected large polycyclic rigid ligands, preferably cross-linked large polycyclic ligands with bleach activators and / or organic percarboxylic acids, Combinations of hydrophobic and / or hydrophilic bleach activators are preferred. More particularly, the present invention relates to the catalytic oxidation of soils and stains and the inhibition of dye transfer during laundering of fabrics, said soils and stains using cleaning compositions comprising bleach activators and / or organic percarboxylic acids and said metal catalysts. For example on surfaces such as fabrics, dishware, counter tops, dentures, etc. The composition comprises a bleach activator and / or an organic percarboxylic acid, a detergent adjunct component and a catalyst, wherein the catalyst comprises a combina...
