Electric Literature of 695-53-4, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 695-53-4, molcular formula is C5H7NO3, introducing its new discovery.
Photographic yellow dye-forming couplers
A photographic element comprises a light sensitive silver halide emulsion layer having associated therewith an open chain alpha-carbonyl acetanilide yellow dye-forming coupler having the formula: wherein R1is selected from the group consisting of alkyl, aryl, heterocyclic, and amino groups, provided that R1may form a ring bonded to another carbon atom which is a member of Ring “A”; each R2is independently selected from the group consisting of those substituents having a Hammett’s sigma value of 0 or less, and m is from 0 to 4; each R3and R4for each of the n carbon atoms is independently selected from the group consisting of hydrogen, alkoxy, aryl, heterocyclic, aryloxy, and alkyl groups, and n is 0 to 16; each R5independently selected from the group consisting of amino, alkyl groups, and groups linked to the “B” ring by oxygen or sulfur, and p is 1 to 3, provided that two R5groups may join to form a ring; R6is selected from the group consisting of alkyl, aryl, and amino groups; each L is independently a divalent linking group and q is 0 to 3; and Ring “A” is bonded indirectly to the 3-, 4-, or 5-position of Ring “B”; and Z is hydrogen, or a group capable of coupling-off when the coupler reacts with an oxidized color developing agent.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 695-53-4 is helpful to your research. Electric Literature of 695-53-4
