The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.33100-27-5, Name is 1,4,7,10,13-Pentaoxacyclopentadecane, molecular formula is C10H20O5. In a Article，once mentioned of 33100-27-5, SDS of cas: 33100-27-5
Complexation constants of the proton, Kf(LHS+), and of the hydronium ion, Kf(LH3O+), with a host of crown ethers (L) in acetonitrile have been determined.With 12-crown-4 the proton yielded LHS+ and (a sandwich complex?) L2HS+.The dibenzo effect in 18-crown-6-on Kf(LHS+) and Kf(L3O+) is 2 orders of magnitude greater than that on Kf(LK+).It is concluded that the proton as well as the hydronium ion is complexed by hydrogen bonding to the ether oxygens in addition to ion-dipole interaction with the oxygens.The exchange constant between LHS+ and Ag(1+) has been determined in propylene carbonate and found equal to the ratio of formation constants of the complexes.The mobility (lambda0) of the hydronium ion complex with dicyclohexano-18-crown-6 in acetonitrile (cis, syn, cis) has been found equal to 68.3 (25 deg C) and is considerably greater than the literature value of 53.3 of the complex with potassium.
The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 33100-27-5 is helpful to your research., SDS of cas: 33100-27-5
