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. 相似文献

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. 相似文献
