This main common synthesis methods of aroyl chloride were introduced,and analysed these methods on the economy and environmental protection.

The synthesis of diaryl sulfones from arensulfonyl chloride with aromatic hydrocarbons is conducted under Friedel Crafts conditions in the absence of solvent using ZrO 2/S 2O 8 2- solid superacid as catalyst in 79%～93% yields.

The effect of the technology of thermal stretching on chloride-polysulfonamide (Cl-PSA) fiber spun by wet methods is studied in this paper.

A new tripodal aryl amide type ligand,1,1,1-tris{[(2′-benzylaminoformyl)phenoxyl]methyl}-p-toluene sulfonyl aminomethane,and its Eu(NO_3)_3,Tb(NO_3)_3 complexes have been synthesized.

The preparation of aryl amides by selective oxidation of aryl nitriles using sodium tungstate as catalyst and sodium percarbonate or sodium carbonate-hydrogen peroxide as the oxidant in a methanol and water solution was studied.

Coordination polymer {[La(NO3)3]2·L3}n {L= 1,4-bis{[2'-(benzylaminocarbonyl)-phenoxyl]-methyl} benzene has been synthesized by the reaction of an aryl amide type bis-monodentate ligand and La(NO3)3·6H2O, and the crystal structure of this complex has been characterized by X-ray diffraction analysis.

Preparation and influence factors of aromatic polyamide nanofiltration membrane;

Preparation and Separation Performance of Aromatic Polyamide Nanofiltration Membrane;

Based on the relationship between polymer structures and properties, model tri-block copolymers with a chain sequence of aliphatic polyamide-aromatic polyamide-aliphatic polyamide were designed and synthesized by the so-called "one step" and "two step" high-temperature polycon-densation.
