Manganese oxalate – a Bio-inspired bleach catalyst was written by Reinhardt, G.;Best, M.;Ladwig, M.. And the article was included in SOFW Journal in 2011.Reference of 10543-57-4 This article mentions the following:
Sustainability driven trends to lower temperatures and shorter washing times require the use of alternative bleaches in automatic dishwashing applications. α-Manganese oxalate dihydrate, a synthetic analog of the mineral Lindbergite, offers a new proposition for a low temperature bleach catalyst in automatic dishwashing detergents. In combination with sodium percarbonate, the biodegradable catalyst enables tea stain removal at temperatures below 50°C where common bleaches fail. Storage stable co-granules comprising the catalyst in combination with the activator tetraacetyl ethylenediamine offer excellent tea stain removal while ensuring a high level of hygiene even at low temperatures In the experiment, the researchers used many compounds, for example, N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4Reference of 10543-57-4).
N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4) belongs to amides. Because of the greater electronegativity of oxygen, the carbonyl (C=O) is a stronger dipole than the N–C dipole. The presence of a C=O dipole and, to a lesser extent a N–C dipole, allows amides to act as H-bond acceptors. Amides can be recrystallised from large quantities of water, ethanol, ethanol/ether, aqueous ethanol, chloroform/toluene, chloroform or acetic acid. The likely impurities are the parent acids or the alkyl esters from which they have been made. The former can be removed by thorough washing with aqueous ammonia followed by recrystallisation, whereas elimination of the latter is by trituration or recrystallisation from an organic solvent.Reference of 10543-57-4
