IR Spectra of Dicarboxylate of Alkali-earth Metal;

Their heat stabilization effect on PVC was tested by Congo red method and heating method,which showed all the dicarboxylates had reasonable thermostability.

Aim To synthesize O acyl or S acyl amino acids by condensation of dicarboxylic acids and amino acids.

Effect of dicarboxylic acids on phases compositions of calcium oxalate;

Supramolecular Complexes and Titanocene Complexes Constructed by Dicarboxylic Acids (H_2DTB, H_2TDA) and Containing N and O Ligands;

According to dicarboxylic acid anhydrides can rapidly react quantitatively with aniline to form anilic acid in special conditions.

Development of down stream products of dicarboxylic acids such as dicarboxylic acid esters and separation of dicarboxylic acid esters can not only enlarge application range of dicarboxylic acids and significantly increase added value of three dicarboxylic acid esters but also extend industrial chain, which means great economic and social benefit.

This paper research on the synthesis of salt of polyacid,the excellent results have been achieved by using this sodium polyacid in detergent to replace sodium triphosphate and ester of this polyacid in PVC products to replace phthalate of n-butal.
