The synthesis,antimicrobial activity and absorption characteristics of some novel heterocyclic disazo dyes

Aniline derivatives were diazotized and coupled with 3-aminocrotononitrile to give the corresponding 2-arylhydrazono-3-ketiminobutyronitriles. Cyclization of these arylhydrazono derivatives with hydrazine monohydrate afforded 5-amino-4-arylazo-3-methyl-1H-pyrazoles which were subsequently diazotised and coupled with malononitrile to yield a series of pyrazolylhydrazonomalononitriles. These compounds were then reacted with hydrazine monohydrate to provide 10, novel, heterocyclic disazo dyes, which were characterized by elemental analysis and spectral methods. The antimicrobial activity and absorption characteristics of the dyes were also examined in detail.     

Synthesis,spectral properties and application of novel disazo disperse dyes derived from polyester waste

Terephthalic dihydrazide was obtained through aminolytic depolymerisation of polyester bottle waste by using hydrazine hydrate. It was further reacted with 4‐aminobenzoic acid in the presence of polyphosphoric acid to obtain a cyclic compound, 4,4′‐[5,5′‐(1,4)‐phenylene)bis(1,3,4‐oxadiazole‐5,2‐diyl)dianiline, having a heterocyclic moiety. Diazotisation of this compound followed by coupling with various N,N‐disubstituted anilines afford a series of novel disazo disperse dyes. The structures of these synthesised dyes were confirmed by elemental analysis and Fourier Transform–infrared, proton nuclear magnetic resonance and mass spectroscopy. Ultraviolet–visible spectra of these azo dyes in different polar solvents showed considerable variation in the wavelength of maximum absorbance (λ_max). Application of these dyes on polyester and nylon fabrics using high‐temperature dyeing methods gave brilliant yellowish red hues with fair to moderate light fastness and very good to excellent wash fastness and sublimation fastness.     

Synthesis, spectral characterisation and antimicrobial activity of new disazo dyes derived from heterocyclic coupling components

Two series of new disazo dyes were prepared by diazotising 4,4'-diaminodiphenylsulphonamide and 4,4'-diaminodiphenylurea and coupling with 3-methyl-1-phenyl-pyrazoline-5-one, 2-methylindole, 8-hydroxyquinoline, 2-phenylindole, 1-methyl-2-phenylindole, 3-amino-1-phenyl-pyrazoline-5-one. These dyes were characterised by ultraviolet–visible, Fourier transform infrared, nuclear magnetic resonance spectroscopic techniques and elemental analysis. The spectral characterisation of the dyes was evaluated with respect to visible absorption properties in various solvents. The effects of acid and base on the visible absorption maxima of the dyes were also reported. In addition, the antimicrobial effect of the dyes was evaluated.     

Cohesion parameters for surfaces, pigments, and fillers

Conclusions  The surfaces of pigments, fillers, plastics, fibres, and other materials can be characterized by cohesion parameters. These have a solid fundamental basis. Greater insight into the make-up of a product is possible when one also has the cohesion parameters for the polymer and solvents which are used in connection with these pigments and fillers. The critical surface tension and wetting tension are single point determinations. Cohesion parameters allow a more complete characterization of surfaces than do these single point measurements, and at the same time allow insight as to how the single point measurements fit into the overall energy picture for the product. A simple test method based on the spontaneous spreading of small droplets of known liquids is suggested to determine whether or not a surface is contaminated.

Characteristics of pigments,modification, and their functionalities

Novel treatments of pigments with inorganic materials have tremendous industrial and commercial prospects. Specific treatment of pigment has a marked effect on its behavior during application. The treatment allows a broad modification of the surface characteristics of pigment particles which leads to improved functionalities. Surface modification of pigments is achieved via coating, polymerization with modifying reagent, treatment with derivatives or polymers, which alter either the optical, conductivity or dispersibility during processing and application. These and many other distinguishing factors that affect the characteristics of pigments such as the class, crystal structure, particle morphology, particle size, hiding power, pigment volume concentration, surface character, and surface treatment have been reviewed. Various organic pigments such as those from fungus and bacteria, and the various families of pigment types such as metallic pigment, light interference, and diffractive pigments which presents decorative quality such as leafing, nonleafing, pearlscent, and Fabry‐Perot effects on substrates have also been reviewed in addition to those from inorganic sources with emphasis on the structure and physiochemical modifications using metal and nonmetal Ions.
