recently reported the antimicrobial properties of disperse dyes based on 3-oxo-2(phenylhydrazono) -3-p-arylpropionaldehydes.
We previously reported the synthesis of some novel disperse dyes based on substituted pyridines and their derivatives, oxazine, carbooxyanilide and thiocarbamate and evaluated their insecticidal and antifungal activity [18, 19].
Synthesis of disperse dyes: Eight novels disperse dyes based on substituted pyridines and their derivatives, oxazine, carbooxyanilide and thiocarbamate were synthesized using substituted aryl amines as chromophores.
ASD will have their daily classes winding up at 3:45 pm, as usual, while DESS and Cambridge International will continue to disperse
Drais Perl ball mills finely disperse and homogenize high-, medium-, and low-viscosity materials and stiff pastes.
FM mixer has the ability to frictionally elevate the temperature of material being mixed and to disperse agglomerated fine powders including most pigments.
As non-sodic soils were not expected to disperse spontaneously, for analysis the `mechanically dispersed' and `not dispersed' categories were amalgamated into a single, `not dispersed' category.
From the concept that a soil with a Ca: [Mg1:5 and ex] ratio [greater than or equal to] 1 will not disperse, it was determined how often this was correct for these samples.
The aim of this study was to determine whether or not the easily dispersed colloidal materials differ in their properties from colloidal materials that do not disperse easily.
Organic materials such as fungal hyphae and fine roots can help prevent dispersion by stabilising macroaggregates and thereby reducing the surface area from which clay can disperse (Tisdall 1996).
Single powder based products may include accelerators, zinc oxide, sulfur, magnesium oxide, calcium oxide or other difficult to disperse
