Natural colorants play a vital role in the production of eco-leather by substituting environmentally hazardous and toxic synthetic dyestuffs. In this study, natural dye is extracted optimized from bark Ficus sycomorus, plant species locally known as shola, designing different combinations concentration, temperature, time parameters. A 120 g/l concentration at temperature 1000°C for 60 minutes s...

A new series of fluorinated quinoline -1,4-dithiones 3(a-f) were obtained by the treatment 3-aryl-2-hydrazino-quinolines 1(a-f) with isobenzo furan-1,3-dithione 2 in presence p- toluene sulphonic acid (PTSA) solid state at room temperature as one pot. All products are monitored TLC and isolated GC furthermore confirmed spectral analysis.

Abstract The toxicity of heavy metals in the aquatic environment is a serious challenge to global community. Even at low concentrations, have cumulatively destructive effect on living organisms environment. Biomass wastes been investigated for removal published literature; however, performance and capacity biomass represents drawback towards effective application. Therefore, this study, waste s...
