Separation of xylenes by enclathration [PDF]

Chemical Communications, 2015
The isomers of xylene have been separated by enclathration using three host compounds: 9,9′-bianthryl (H1), 9,9′-spirobifluorene (H2) and trans-2,3-dibenzoylspiro[cyclopropane-1,9-fluorene] (H3).

Determination and modeling of binary solid-liquid equilibria of para-xylene/meta-xylene, para-xylene/ortho-xylene by DSC method

Fluid Phase Equilibria, 2022
Abstract Solid-liquid equilibria of three binary mixtures consisting of para-xylene, ortho-xylene, meta-xylene and ethylbenzene were investigated in this study using differential scanning calorimetry (DSC) method, the mixtures were cooled to -120°C and then heated to 20°C at different heating rates, eutectic phase diagrams were observed for para ...

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.

The developmental toxicity of xylene and xylene isomers in the hydra assay

Toxicology and Applied Pharmacology, 1986
Two laboratories tested multiple forms of xylene for their developmental toxicity hazard potential (A/D ratio) by means of the hydra assay. The three isomers, as well as a solution of mixed xylenes, all interfered with development (D) at or near to concentrations that also were toxic to adult (A) hydra.

Oral Toxicology Studies with Xylene Isomers and Mixed Xylenes

Drug and Chemical Toxicology, 1988
Xylene isomers and mixed xylenes were administered to male and female Sprague-Dawley rats to evaluate their effects on standard toxicological parameters which included body and organ weights, hematology, serum chemistries, urinalysis and histopathological examination.

Selective Conversion of CO2 into para-Xylene over a ZnCr2O4-ZSM-5 Catalyst.

ChemSusChem, 2020
An Oxide-Zeolite (ZnCr 2 O 4 -ZSM-5) catalyst for directly converting CO 2 to aromatics was designed and developed. It showed high PX/X (the C-mol ratio of Para-Xylene to all xylene) and PX/Aromatics (the C-mol ratio of Para-Xylene to aromatics) ratios ...

Alternative pathways foro-xylene orm-xylene andp-xylene degradation in aPseudomonas stutzeri strain

Biodegradation, 1993
Pseudomonas stutzeri OX1 is able to grow ono-xylene but is unable to grow onm-xylene andp-xylene, which are partially metabolized through theo-xylene degradative pathway leading to the formation of dimethylphenols toxic to OX1.P. stutzeri spontaneous mutants able to grow onm-xylene andp-xylene have been isolated.

Record-setting selectivity for p-xylene by an intrinsically porous 0D metallocycle.

Journal of the American Chemical Society, 2020
In its crystalline state a dinuclear Cu-based metallocycle discrimi-nates between the three isomers of xylene with liquid-phase selec-tivity in the order p-xylene  m-xylene  o-xylene. This selectiv-ity holds over a wide concentration range, with para-

Exposure test for xylenes

International Archives of Occupational and Environmental Health, 1976
The relation between the mean all-shift concentration of xylene vapor in the atmosphere and the amount of conjugated toluic acids excreted in urine of exposed persons, was derived from the results of 38 experiments with pure xylene isomers and with a mixture of isomers at ratio 1:1:1.
