Some novel azo disperse dyes prepared 4-(N-acetyl amino) 2-methyl phenacyl chloride was reacted with aniline Then resultant product were hydrolysis to give yield 1-(4-amino-2-methyl phenyl)2-(phenacyl) ethanone.Then diazotized by the standard procedure and coupling with various components. Thus a series of azo disperse dyes has been prepared. After syntheses compounds were characterized by chemical as well as instrumental methods. like melting point, elemental analysis and IR spectral studies. Source

Complexes of 2-(8-Quinolinol-5-yl) - amino methyl-3- (4- Methoxy Phenyl)-5-(4-chloro Phenyl)-Pyrazoline with Cu(II), Mn(II) and Co(II) have been synthesized and characterized using elemental analysis, IR spectra, PMR spectra, Reflectance spectra, Conductivity measurements and antimicrobial activity. These studies revealed that they are having octahedral geometry of the type [ML2 (H2O)2].The compounds show net enhancement in activity on coordination of metals with ligand but moderate activity as compared to standard drugs.

Cyclohexanone-formaldehyde (CHF) resin was brominated and the brominated CHF (BCHF) was then reacted with excess aromatic diamines. The aminated CHF resins designated as ACHFs (modified ketone resin) were characterized and then applied as epoxy resin curing agents. Thus, the curing of the commercial epoxy resin diglycidil ether of bisphenol-A (DGEBA) by ACHFs was monitored by differential scanning calorimetric (DSC), based on the the DSC scans, the glass fiber-reinforced composites of DGEBA-ACHF systems were prepared and characterized by chemical resistivity and mechanical properties.
