Each node contains a C(R), C(R1)(R2), or a C(R)2 unit. Each R may be H, alkyl, cycloalkyl, cylcoalkenyl, alkenyl, aryl, alkynyl, alkylaryl, halogen, alkoxy, or phenoxy, CH2CF3, CF3 and combinations thereof, or form a substituted or unsubstituted benzene ring, or together with a paired R substituent bound to the same carbon atom form a cycloalkyl or cycloalkenyl ring; M is a transition metal; Q is any counterion; and L is any labile ligand.

摘要： N-acyl compounds known as bleach activators especially tetraacetylalkylene diamines, are reacted with a peroxygen source in aqueous solution at an acidic pH to form an oxidising product which is a stronger oxidising agent than the peroxygen source used as the starting material. The product solution is used for instance as a bleach or disinfectant. The activator and peroxygen source may be provided as a concentrate product ready for dilution with components able to produce acidic pH in the aqueous solution. The product is, for instance in particulate solid form containing granules of activator and different granules of peroxygen source.

摘要： The invention provides a method for the application of a bleaching agent to a substrate, the method comprising the treatment of the substrate in an aqueous system comprising a liquid bleaching agent in a closed container, the treatment being carried out at a ratio of liquor to substrate which does not exceed 3:1. Typically, the method is applied to the bleaching of textile fibres and may optionally comprise a bleaching and scouring treatment. The invention also provides a method for the removal of surplus bleaching agents following the bleaching treatment, the method comprising not more than three aqueous wash-off treatments of the substrate. In addition to facilitating the use of much reduced liquor levels, the method also allows for significant reductions to be achieved in usage levels of bleaching agents, auxiliary agents and rinsing agents, thereby reducing generation of waste liquors requiring disposal. Furthermore, treatment temperatures are also significantly lower than for prior art methods, providing yet further benefits in environmental and cost terms.
