nalant@yahoo.com Abstract A series of 5-nitro-3-[(5-nonsubstituted/methyl-4-thiazolidinone-2-ylidene)hydrazono]-1H-2indolinones (3a-j and 4a-h) was synthesized by cyclization of 5-nitro-1H-indole-2‚3-dione-3thiosemicarbazones (1a-k) with ethyl bromoacetate or ethyl 2-bromopropionate. The primary antiviral activities of the new hydrazonoindolinone derivatives‚ the previously reported 5-nitro1H-indole-2‚3-dione-3-thiosemicarbazones (1a-k) and 1-morpholino/piperidinomethyl-5-nitroindole-2‚3-dione-3-thiosemicarbazones

Laboratory #16: Analysis of Grease in Water by Solvent Extraction Experiment Date: 2/19/10 Due Date: 2/26/10 II. Objective The goal of this lab was to determine the amount of impurity‚ in the form of oil‚ in water using the method of solvent extraction‚ also known as liquid-liquid extraction‚ a method of separating two materials with different physical and/or chemical properties. Two methods of evaporation will be used to finally determine the concentration of impurity- one using an explosion-proof

Ethyl alcohol is a 2-carbon alcohol with a molecular formula of CH3CH2OH (Smith‚ 2014). Ethyl alcohol is an inebriating substance commonly found in alcoholic beverages. This substance acts as a central nervous system depressant and is commonly referred to as a “psychoactive drug‚” which is capable of altering brain function. This substance can be lethal if consumed in high doses. The amount of ethyl alcohol that is consumed can be quantified by blood alcohol content (BAC). BAC is measured as weight

PICRIC ACID (DIRECT DYE): Take about 60 mL of water in a 400 mL beaker. Add 2-3 drops of concentrated sulphuric acid and about 0.5 g of Picric Acid to it. Stir the solution with a wooden stick and warm over a hot water bath. Immerse one piece of each wool‚ cotton‚ polyester‚ nylon and terecot into it. When the pieces are thoroughly wetted in dye solution remove these with the help of forceps. Wash these with the help of warm water till the washing is colourless. Dry the pieces and note the results
