Application of 6640-47-7, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.6640-47-7, Name is Quinoxaline-2,3-diamine, molecular formula is C8H8N4. In a article£¬once mentioned of 6640-47-7
New bisanthraquinone azomethine dyes
The present invention relates to novel colorants based on bisanthraquinone azamethine derivatives or their metal complexes for the mass coloring of polymers, either for polar polymers such as polyamides, polyesters, polycarbonates and ABS; or for non-polar polymers such as polyethylene and polypropylene.The novel colorants are characterized by i) a central substituted or unsubstituted annealed aromatic ring system comprising at least one heteroatom and ii) two anthraquinone moieties attached thereto by azamethine bridges.The novel colorants provide for excellent compatibility with the polymer substrate, excellent heat stability and light fastness.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 6640-47-7
