Selective toluene methylation to p-xylene: current status & future perspective

Catalysis reviews, 2022
Industrially, petroleum naphtha reforming and steam cracking are two major multistep and energy-intensive sources for p-xylene production. Additionally, p-xylene is also produced by selective toluene disproportionation, heavy (C9) aromatics trans ...

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-

Poly(p-xylene disulfide) and poly(p-xylene tetrasulfide): synthesis, cure and investigation of mechanical and thermophysical properties

, 2020
In this work, two polysulfide polymers were synthesized using aromatic organic monomer (α,α′-dichloro-p-xylene) and sodium disulfide (Na2S2) and sodium tetrasulfide (Na2S4) aqueous monomers. Then, the curing process of the polymers was carried out at 170°

The Origin of p-Xylene Selectivity in a DABCO Pillar-Layered Metal-Organic Framework: a Combined Experimental and Computational Investigation.

ACS Applied Materials and Interfaces, 2019
Separation of p-xylene (pX) from xylene isomers is an important and challenging issue due to the similar physical properties between the molecules. In this study, we found that 1,4-diazabicyclo[2.2.2]octane (DABCO) has a selective interaction with pX and

Ultrafast, Highly Sensitive, and Selective Detection of p-Xylene at Room Temperature by Peptide-Hydrogel-Based Composite Material

ACS Applied Polymer Materials, 2019
A peptide/carbon dot (CD) composite xerogel is used as a selective p-xylene VOC (volatile organic compound) sensor. The fiber formation by the peptide allows us to attain a semiconducting property, whereas the presence of the CD amplifies the sensitivity.

Binary Adsorption Equilibrium and Breakthrough of n-Butyl Acetate and p-Xylene on Granular Activated Carbon

Industrial & Engineering Chemistry Research, 2019
Compared with abatement methods (regenerative thermal oxidizer, regenerative catalytic oxidizer, etc.), the adsorption–desorption combined method has been considered as a sustainable way to treat and recover volatile organic compounds (VOCs) from off ...
