Electric Literature of 1679-47-6, 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, 1679-47-6, molcular formula is C5H8O2, introducing its new discovery.
Heterocyclic esters of alkylphenyl benzopyranopyridines represented by the formula STR1 wherein R1 is hydrogen, loweralkyl, loweralkanoyl, cycloalkylloweralkyl, cycloalkylloweralkanoyl, loweralkenyl, loweralkynyl, haloloweralkenyl, phenylloweralkyl, phenylloweralkenyl or phenylloweralkynyl; R2 is loweralkyl; R3 is STR2 WHEREIN X is a straight or branched chain alkylene group having from one to eight carbon atoms, a is an integer from 1 to 4, b is an integer from 1 to 4 and Z is CH2, O, S or NR7, with R7 being hydrogen or loweralkyl, with the limitation that when X is O, S or NR7, the sum of a and b is 3 or 4; and R8 is hydrogen or loweralkyl; Y is a straight or branched chain alkylene group having from one to ten carbon atoms; and each R4 and R5 and R6 are the same or different members of the group consisting of hydrogen, halo, trifluoromethyl or loweralkyl; and the pharmaceutically acceptable acid addition salts thereof.
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 1679-47-6 is helpful to your research. Electric Literature of 1679-47-6
