SYNTHESIS, PHYSICO-CHEMICAL CHARACTERIZATION AND BIOLOGIC ACTIVITY OF A NEW NICKEL COMPLEX WITH 2-CYANOGUANIDINE

A new complex of nickel with 2-cyanoguanidine and acrilato ion as ligands was synthesised. The physico-chemical characterisation revealed the unidentate coordination mode of ligands as well as the metallic ion octahedral...

A NEW N,N-DIMETHYLBIGUANIDIUM DERIVATIVE – SYNTHESIS AND STRUCTURAL CHARACTERISATION

A new N,N-dimethylbiguanidium derivative (C4H12N5)2(NO3)(ClO4) has been synthesised and characterised by single crystal X-ray diffraction. The derivative crystallizes in the monoclinic C2/c space group and the N,N-dimeth...

CHARACTERIZATION BY DYNAMIC THERMAL METHODS OF SOME BIS-AZOPOLYETHERS WITH AN OCTAMETHYLENE SPACER

This paper presents the characterization by dynamic thermal methods of some bis-azopolyethers with an octamethylene spacer. For the thermal analysis we used a MOM-Budapest derivatograph which enables the simultaneous rec...

A DSC STUDY OF gamma-AMINOBUTYRIC ACID GAMMA IRRADIATED

The behaviour on heating of irradiated with gamma rays and non-irradiated γ-amino-butyric acid (γ-AMB) was investigated by means of differential scanning calorimetry. γ-AMB decomposes before melting.
