Comparison of vanillin and isovanillin photolysis in aqueous solutions
General kinetic regularities of reactions of stationary and laser photolysis of 3-methoxy-4-hydroxybenzaldehyde (vanillin) and 3-hydroxy-4-methoxybenzaldehyde (isovanillin) are investigated by the method of nanosecond laser flash-photolysis. The 4th harmonic of a Nd:YAG laser (λexc = 266 nm) with pu...

| 520 | 3 | |a General kinetic regularities of reactions of stationary and laser photolysis of 3-methoxy-4-hydroxybenzaldehyde (vanillin) and 3-hydroxy-4-methoxybenzaldehyde (isovanillin) are investigated by the method of nanosecond laser flash-photolysis. The 4th harmonic of a Nd:YAG laser (λexc = 266 nm) with pulse duration of 7 ns, output power of 100 MW/cm2, and delay time of 30 ns was used as an excitation source. As a result of photolysis, the same photoproducts are formed in the region of absorption at 715 nm. The rate constants of vanillin and isovanillin decomposition obey the first order law and are 2.3106 and 2.5106 s-1, respectively | |
