Our results indicate that the benzidine/phenol adducts are analogous to the indoaniline dyes, differing only in substitution of a biphenyl group for a benzene ring. The reaction of benzidine di-imine with endogenous phenols may represent a new pathway for detoxication, removing potentially harmful ...

The mechanism of formation and the nature of the distribution of this pore structure is discussed. From the isotherms and heats of adsorption of benzene and n-pentane vapor the principal structural features of ultrastable dealuminized Y zeolite have been determined: micropore volume W o =0.18 cm ...

Recently, tar product has been defined as all the hydrocarbons with a molecular weight higher than benzene [4]. Compositional studies on liquid tar by-products have resulted in several research papers in recent years. Knowledge of the composition of liquid tar by-product is important to better ...
benzene, toluene, and mixed xylenes (BTX) in a process such as steam cracking. High-value chemicals are demanded by plastics, synthetic fibers, and rubber production. Ammonia and methanol production highly rely on natural gas and coal which makes those chemicals one of the most emission-...
According to that, although both distillation methods share 38 common components in their essential oils, including 10-epi-g-eudesmol, but the total components responsible for the fragrant odor, particularly for terpenoids (the sesquiterpenes) and benzene derivatives, are shown to be higher in the ...
