Highly selective synthesis of renewable p-xylene (PX) from bio-based 2,5-dimethylfuran (DMF) and ethylene was successfully realized on H-Beta zeolite catalysts with further Al-modifications. The influ...
Studies on the use of gas phase applications of light emitting diodes (LEDs) in photocatalysis are scarce although their photocatalytic decomposition kinetics of environmental pollutants are likely di...
In this study, changes in testicular tissues of rats subjected to xylene and formaldehyde inhalation were evaluated. Three experimental groups were included in the study. Each group of rats was expose...
The chemical and physical differences of secondary organic aerosol (SOA) formed at select isothermal temperatures (278 K, 300 K, and 313 K) are explored with respect to density, particle volatility, p...
Biodegradation kinetic behaviors of ethyl acetate and xylene in a sugarcane bagasse biofilter were investigated. Microbial growth rate, biochemical reaction rate and kinetic analysis were inhibited at...
In order to evaluate the effectiveness of the Iranian made charcoal tubes in the field , 60 local made and 60 imported ones (SKC type) were randomly selected and placed side by side for sampling aroma...
Background: Determination of organic pollutants usually requires extraction of the pollutants from samples, using hazard­ous solvent. Solid phase micro-extraction (SPME) is a solvent-free equilibr...

Van der Wals团簇ο-xylene N2的共振双光子电离光谱。
The present study investigated the effects of chelating agents on the aromatic hydrogenation activity and the surface fine structure of NiW/Al2O3 catalyst. NiW/Al2O3 catalyst was prepared from impreg...
Mehm WJ, Reimers SD, Casale JG. A Procedure for Removing Xylene Fumes from Hyperbaric Chamber Air. J. Hyperbaric Med 1990; 5(1):23-27.
Secondary organic aerosol (SOA) formation from the photooxidation of m-xylene, toluene, and benzene is investigated in the Caltech environmental chambers. Experiments are performed under two limiting ...
Consecutive reactions of adducts, resulting from OH radicals and aromatics, with the tropospheric scavenger molecules O2, NO and NO2 have been studied for benzene, naphthalene, toluene, m- and p-xylen...
用介观动力学在介观层次上对不同组分的PluronicL64/水/p-xylene三元体系的相分离进行了研究,得到了和实验相吻合的结果。计算表明对于纯p-xylene溶剂和有含少量水的p-xylene溶剂,体系没有发生相分离,随着水的含量增加,体系发生了明显的相分离,产生了不同形态的胶团。本研究还通过对比不同溶剂组分下的体系介观形貌,讨论了水在体系相分离中的作用。同时通过分析模拟了1000步后体系中...
Preparation and pervaporation of a palygorskite/polyacrylamide inorganic-organic hybrid membrane for separating m-/p-xylene isomers.
