Styrene is an important organic raw material for chemical industry. Normally it is made by dehydrogenization of ethyl benzene at adiabatic and vacuum conditions.
苯乙烯是重要的有机化工原料,通常采用负压绝热脱氢法,然后再精馏分离获得高纯度的苯乙烯产品。
The invention also relates to the catalyst C and methods involving the cross-linking of silicon by dehydrogenization with condensation (anti-cling coating on paper).
本发明还涉及催化剂C和包含通过脱氢缩合交联有机硅的方法(在纸张上的非粘涂层)。
The fatigue life-spans of specimens after dehydrogenization heat treatment and crystallization heat treatment are all decreased observably, which is caused by the tension internal stress.
