Blue Dye Synthesis

experiment was to synthesize two organic dyes then observe their effective dye strength on various synthetic and natural materials. This was achieved by means of chemical reactions outlined below, heat to increase the reaction rate, ice baths to precipitate out the product, vacuum filtration to isolate the product, washing with water and 95% ethanol to purify the product, and dying of the clothe to observe dye effectiveness. The test of the effectiveness of the dye required that the fabric absorb one

Commercialization of Photochromic Dyes and Products Background While most people, including this author, hold quite optimistic views of the photochromic industry, very little commercial success has been realized. In Professor Giacomo Ciamician’s famous paper on photochemistry of the future, he predicted that photochromic clothing would be popular. It turns out that he was right. His paper was written in 1912 and photochromic clothing was not commercially successful until the early 1990’s.

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 coupling

approach of affinity chromatography with extremely significant results is dye-ligand affinity chromatography. In this type of affinity chromatography, dyes compose the group of ligands than are employed in the technique (Hage et al., 2012). The initial motivation for scientists to investigate more about dye ligand affinity chromatography was given after the interactions that took place between Blue Dextran, a Cibaron Blue and dextran conjugate, which is used as a void marker in size-exclusion chromatography

price being at one time worth more than gold. Apart from its associations with royalty, the color, which ranged from more blue to more red, had strong associations with blood. The chemical makeup of Tyrian purple is strikingly related to the chemical pigment found in pea plants in India.

1. INTRODUCTION Environmental problems related with hazardous wastes and toxic water-pollutants have attracted much attention towards itself. Organic dyes are one of the major groups of pollutants in wastewaters released from textile and other industrial processes. Photocatalysis is a simple and promising technique for solving various current environmental issues. Semiconductor absorbents offer a great potential for eliminating the organic pollutants present. Semiconductor photocatalysts for example

Fluorescein dye has been used for a very long time and it serves many purposes within the lab and in everyday life. As a product fluorescein appears to be a brownish-orange powder solid that appears to be bright, neon green under a UV lamp. Fluorescein, Yellow No.7 dye, is used as a color addictive to food, medications, and beauty products.2 It is also used as a fluorescent tag for labeling antibodies that will be targeting specific areas of a cell1 or identify and locate life threating thrombotic

were utilized starting chemicals and purchased from Sigma–Aldrich Chemise (Germany). Agarose was purchased from Fischer- Biotech (GE Heath care). Tracking dye (0.25 % bromophenol blue, 40 % sucrose, 0.25 % xylene cyanole and 200 mM EDTA) and Ready-load 100 bp DNA ladder were used as the native size DNA and purchased from Bio labs. 2.1 Synthesis of the investigated bi-dentate CBAP imine ligand The investigated bi-dentate CBAP imine ligand was synthesized by adding 4-chloro Benzaldehyde(10mmole

electrical field at a voltage of 1-5 V/cm and DNA will migrate towards the anode (red lead). For correctly attached leads: bubbles are generated at electrodes, bromophenol blue migrates from tank to walls. The electric field must be applied till bromophenol blue and xylene cyanol FF have migrated to a third of the gel. • Once DNA/dye samples have separated enough to be detected, the electric current is switched off and the leads are taken off the tank. Alternatively, the gel can be stained by soaking

This antibiotic acts by limiting normal protein synthesis. Streptomycin is effective against E. Coli, gram-negative bacilli, as well as many cocci. Neomycin an antibiotic derived from a strain of Streptomyces fradiae. Neomycin effectively destroys a wide range of bacteria. Kanamycin an antibiotic

Introduction In the past century extensive research has been conducted on porous organometallic compounds for use in various material applications. Although numerous compounds containing Lewis bases, such as nitriles and bipyridines and have been reported to be successful at the sorption of small molecules, the desorption of the guest often leads to structural collapse of the host. 1,2 Metal-organic frameworks (MOFs) have shown to be a valuable class of newer materials that can support permanent
