IR spectra analysis of lanthanide(M=La,Ce)complexes with carboxylic acid;

Koch Carbonylation Synthesis of Carboxylic Acids and Its Prospect in Industrial Application;

Adsorption of carboxylic acids by "cage" polyamidoxime adsorbent;

Effect of carboxylic acids on crystallization of calcium oxalate in gel systems;

Correlation analysis of structures and pKa values of carboxylic acids by quantum-chemical descriptors;

NaBH4 can not reduce carboxylic acids,esters,amides,acid chloride,amino acids and their derivatives under ambient conditions,reflux and standing overnight are necessary.

The Syntheses and Characterization of Organotin Carboxylate Compounds;

The results show that the content of shortchain carboxylates (the dominant species are acetate and formate) is relatively high, but that of difuctional species (oxalate) is low.

Three Schiff base cobalt(Ⅱ) complexes containing benzoaza-15-crown-5,CoL1,CoL2 and CoL3 were used in catalytic hydrolysis of carboxylic ester (PNPP,p-nitrophenyl picolinate) as mimic hydrolytic metalloenzyme at pH 7.

Complexes of the Schiff base with morpholino or aza-crown pendants,CoL1 and CoL2,as mimic hydrolytic metalloenzyme,were used in catalytic hydrolysis of carboxylic ester(PNPP) at pH7.

Recent research progresses in the synthesis of carboxylic ester by phase transfer catalyst such as hexadecy trimethylammonium chloride/bromide and tetrabutylammonium chloride/bromid were reviewed.

This paper studied the effect of three kinds of water-reducing agent(lignosulfonate MG,naphthalene sulfonate FDN, polycarboxylate KH-JS)on setting time,fluidity and strength of building gypsum at 28 d,by using scanning electric microscope(SEM),the change of hydrated crystal morphology was also studied.
