These are a result of over production as well as under utilization of adrenalin.

In the hydroxylation of phenol with H〓O〓 in the presence of Ti-ZSM-5, water is best solvent. It produces catechol and hydroquinone simultaneously, and catechol/hydroquinone ratio is approximately 0.85. The results show H〓O〓 utilization ratio increase 14%, when nonoxidizable weak acid HAc is added into the reaction system. Under the conditions of Ti-ZSM-5 as catalyst, phenol/H〓O〓 ratio being 10, a little HAc, temperature 75℃, reaction time 6h, H〓O〓 utilization ratio reaches 74. 6mo1% in the reaction.

In engineering application, we think that the rock laboratory experiments may simulate and reshow rock bursts considering the conditions of coupled static-dynamic loads and rock burst and their comparison. Energy demand of rock burst occurring is revealed through analyzing energy transition of rock failure process under coupled static-dynamic loads. At the same time, the rule of energy utilization under coupled static-dynamic loads is discovered; the measures for rock cracking by utilizing high stress condition in deep rock mass and energy utilization improving are found.
