A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 4180-23-8, Name is (E)-1-Methoxy-4-(prop-1-en-1-yl)benzene, molecular formula is C10H12O.

Toward Rational Design of Amine Solutions for PCC Applications: The Kinetics of the Reaction of CO2(aq) with Cyclic and Secondary Amines in Aqueous Solution
The kinetics of the fast reversible carbamate formation reaction of CO2(aq) with a series of substituted cyclic secondary amines as well as the noncyclic secondary amine diethanolamine (DEA) has been investigated using the stopped-flow spectrophotometric technique at 25.0 degrees C. The kinetics of the slow parallel reversible reaction between HCO3- and amine has also been determined for a number of the amines by H-1 NMR spectroscopy at 25.0 degrees C. The rate of the reversible reactions and the equilibrium constants for the formation of carbamic acid/carbamate from the reactions of CO2 and HCO3- with the amines are reported. In terms of the forward reaction of CO2(aq) with amine, the order with increasing rate constants is as follows: diethanolamine D EA) < morpholine (MORP) similar to thiomorpholine (TMORP) < N-methylpiperazine (N-MPIPZ) < 4-piperidinemethanol (4-PIPDM) similar to piperidine (PIPD) < pyrrolidine (PYR). Both 2-piperidinemethanol (2-PIPDM) and 2-piperidineethanol (2-PIPDE) do not form carbamates. For the carbamate forming amines a Bronsted correlation relating the protonation constant of the amine to the carbamic acid formation rate and equilibrium constants at 25.0 degrees C has been established. The overall suitability of an amine for PCC in terms of kinetics and energy is discussed. Interested yet?
