Hierarchical composite catalysts of MCM-41 on zeolite Beta for conversion of heavy reformate to xylenes

, 2021
Hierarchical composites of MCM-41 on zeolite Beta were synthesized by in-situ hydrothermal technique, characterized and their catalytic performance for converting heavy reformate into valuable xylenes was evaluated.

Purification of m-xylene from the mixed xylenes by stripping crystallization

, 2021
Stripping crystallization (SC) was applied in this work for purification of m-xylene (MX) from the mixed xylenes consisting of MX, p-xylene (PX), o-xylene (OX) and ethylbenzene (EB).

Electron ionization of o-xylene, m-xylene and p-xylene

Chemical Physics Letters, 2013
Abstract Cross sections of electron ionization of three isomeric xylenes, in an electron energy range of 10–200 eV, are measured. The maximum total cross sections are observed at 80-eV electron energy to be 2.24, 2.10 and 2.05 × 10−15 cm2 for m-xylene, p-xylene and o-xylene, respectively.

Intravenous xylene poisoning

Intensive Care Medicine, 1992
A 30-year-old man injected intravenously 8 ml of xylene in a suicidal attempt. After 10 min he developed acute pulmonary failure requiring intubation, controlled ventilation with PEEP and high FiO2. Combined hemoperfusion and hemodialysis were carried out for 4 h.
