    • 4 with a P/B ratio above 1 shows no activity for the GBR on the basis of their results obtained with a pulse reactor. In the present study, material balance between the inlet and outlet of the reactor was poor for several ten minutes just after feeding the reactant. We guess that they measured the catalytic performance at an unstable state during the initial period even if they turned their attention to the dehydration of the catalysts prior to the catalytic examination: J.

    • Sato et al. pointed out the possibility of OXM-silyl ether and CL-silyl ether as the intermediates for the GBR over silicalite-1, although this dehydrated type of intermediate has not been approved afterward in the mechanism proposed for the GBR at silanol nests: H.

    • For example, as is well known for the reactivity of a silylating reagent, an active hydrogen can be protected as a silyl derivative; the order of reactivity is reported as OH > NH > CONH. Also, the order of hydrolysis of silyl derivatives is as follows: CON-Si > N-Si > O-Si: a) T. W. Greene, "Protective Groups in Organic Synthesis," John Wiley & Sons, N.Y. (1981).
