A multi-component detergent, including at least two components, that is contained in a container having at least two chambers, wherein a first component K1 is a first liquid composition, containing at least one catechol metal complex compound of formula (I) ##STR00001##
and at least one free catechol compound of formula (II) or the salt thereof ##STR00002##
with the proviso that the catechol compound of formula (II) and the salt thereof are different from the compounds of formula (I), and a second component K2 is a second liquid composition, containing at least one surfactant. The present invention further relates to the use of the multi-component detergent for removing bleachable stains and a method for washing textiles using the multi-component detergent.

The invention discloses an iron bipyridine complex, a preparation method of the same, and use of the same in polymerization of conjugated dienes the invention provides an iron bipyridine complex, which is used as a primary catalyst showing high activity in the polymerization of polyprene to obtain a polymer with a high branched-chain degree. The polymer has the characteristics of a high molecular weight and narrow molecular weight distribution, and the molecular weight of the polymer can be adjusted by a chain transfer reagent. The obtained poly(conjugated diene) rubber has high branched-chain content and an ultrahigh molecular weight. Because there are a large number of side groups on the molecular chains of the rubber, the rubber is mainly used for preparing high-performance tires and other related rubber products with good wet traction and low friction-induced heat generation.

Catechol metal complex compounds of formula (I) ##STR00001##
are colored and can be used to give color to surfactant compositions. Detergents containing these catechol metal complex compounds do not stain the textile even after repeated use.
