  • Advantages And Disadvantages Of Diazonuim Salts

    997 Words  | 4 Pages

    Introduction: Diazonuim salts are unsaturated compounds which have a trible bond. There was a scientist his name was Griess, this scientist gave Diazo name to diazonuim salts as he thought that two hydrogen atoms in the benzene ring will be replaced by two atoms of nitrogen. Diazonuim salts divided into two types of salts: Aromatic diazonuim salts and alephatic ( non- aromatic) diazonuim salts. Non aromatic salts are less important than aromatic. Under normal conditions, diazonuim salt is highly

  • Preparing Azo Dyes Using Combinatorial Methods For The Formation Of An Azo Dye

    1782 Words  | 8 Pages

    purpose of this experiment was to prepare azo dyes using the combinatorial approach to show the principles combinatorial chemistry. Using combinatorial synthesis, an array of chemicals can be synthesized by using a parallel synthesis to identify potentially valuable compounds. This electrophilic aromatic substitution reaction involved multiple steps to complete, however, no major techniques were used; only the use of a hot place and an ice bath. The specific azo dyes produced in this experiment used

  • The Decolorization Potential of Microorganisms

    (complete decolorization in 2 h), while in sterile, cell free medium decolorization did not occur up to 48 h of incubation suggesting the absence of abiotic decolorization. As RO16 showed complete decolorization in 2 h, this industrially important toxic azo dye was taken for further studies. Lysinibacillus sp. RGS could decolorize RO16 rapidly and thus was found to be better than the bacterial consortium DAS reported by Jadhav et al (2011). To confirm the decolorization, UV-Vis spectroscopic analysis was

  • Lab Report On Dyes And Chemicals

    3.1. DYES AND CHEMICALS Six reactive azo dyes namely, Reactive Violet 5, Reactive Red 2, Reactive Orange 16, Reactive Blue 4, Reactive Black 5 and Reactive Green 19A were generous gifts from Colors India Inc. Pvt. Ltd. Ahmedabad, India. All these dyes were of industrial grade and are widely used in textile industries. Reactive Violet 5 (vinyl sulfone as a reactive group) and Reactive Red 2 (triazin as a reactive group) were used as model azo dyes in this study. All required chemicals and solvents

  • The Health Of The Common American

    In this fun strategy, students use a “phone,” (usually a rounded piece of plastic, like a PVC pipe) to hear themselves. It is effective for building fluency, since students can focus on their speaking. Additionally, they help to keep students focused on instruction. Students monitor their own reading and the classroom is usually quiet because students are encouraged to whisper (hence the name) so that all students can hear themselves (Cadieux, 2012). This strategy is a simple one: practice. The
