The influence of the association patterns of phosphorus–substrates and xylene–substrates on the degradation of xylenes in an alluvial aquifer [PDF]

Journal of the Serbian Chemical Society, 2005
The association patterns of xylene and of total phosphorus with sediment constituents in an alluvial aquifer consisting of clays and sands which had been contaminated by a spill of technical grade xylene were investigated with the aim of assessing the ...

Study of Catalytic Properties of the HoxMg1-xAl2O4 Modified HZSM-5 Zeolite in Conversion of Methanol to C2-C4 Alkenes and p-Xylene

Bulletin of Chemical Reaction Engineering & Catalysis, 2022
Selective conversion of methanol to C2-C4 alkenes and p-xylene is one of the appealing chemical routes. Currently, there are no effective catalysts for the co-production of C2-C4 alkenes and p-xylene from methanol.

Aqua{μ-1,4-bis[(1,4,7,10-tetraazacyclododecan-1-yl)methyl]benzene}(nitrato-κO)dicopper(II) tris(nitrate) trihydrate

IUCrData, 2023
In the title dinuclear CuII complex, [Cu2(NO3)(C24H46N8)(H2O)](NO3)3·3H2O, the two CuII molecules both have a square-pyramidal geometry, but the ligands in the axial positions are different: a water molecule and a nitrate ion.
