CHALCONES A NEW CLASS OF POTENTIAL NONAZO DYES
Keywords:Azo‐dyes, Synthetic chalcones, Optimization of dyeing conditions, Colour fastness
Five substituted chalcones have been synthesized by Claisen‐Schmidt condensation of substituted acetophenones and substituted benzaldehydes in
the presence of a base by conventional and microwave assisted method. They have been characterized by spectral data and evaluated as non‐azo
dyes for dyeing of silk fabric using metallic and natural mordants and their combination. Optimization of different dyeing conditions as well as
washing and light fastness of some selected dyed samples has also been examined.
