Adol Condensation Introduction: This reaction is carried out by adding benzaldehyde and acetone into a flask. The product created is a 1‚5-diphenyl-1‚4-pentdiene-3-one‚ which includes two double bonds‚ and two benzyl ring functional groups. This is a dehydration reaction that occurs twice in order to form the diene. After obtaining the product‚ via vacuum filtration‚ it will be recrystallized and then analyzed for purity by determining both products’ melting point. The two products will be

workshop‚ to produce the powder. The process was similar to that of making kajal. The researchers used two earthen pots—one to keep wood wool and the other to cover it. The wood wool soot deposited on the upper pot was scraped out and washed with acetone. The washed soot was then air dried and oxidised with nitric acid to obtain wsCNPs. The nanoparticle was tested on three types of mosquitoes–Anopheles‚ Aedes and Culex. To monitor the growth and life cycle‚ optical fluorescence microscope was used

procured from Agilent Technologies (USA). HPLC grade acetonitrile‚ acetone and ethyl acetate were supplied by Merck (Mumbai‚ India). Analytical grade sodium chloride (NaCl) and anhydrous magnesium sulfate (MgSO4) was obtained from Merck. Anhydrous magnesium sulfate was activated in a muffle furnace at 400 ºC for 6 hr before to use and kept in desiccators. Individual standard stock solutions of 1000 µg/mL were prepared in acetone in a class A grade volumetric flask of 25 ml capacity by dissolving

Objective: The objective of the lab is to separate the caffeine samples we are using‚ using thin layer chromatography. The solvent we are using for the separation is 3:1 mixture of Chloroform and Acetone. Principle: Thin layer chromatography (TLC) is an important technique that is useful for separating organic compounds. TLC is often used to monitor the progress of organic reactions and to check the purity of products. Separations in Thin layer chromatography involve distributing a mixture of

Restoring Balance LeChâtelier’s Principle and Equilibrium Introduction Chemical equilibrium is a true balancing act. What happens when the balance is disturbed? The purpose of this lab is to observe the effects of concentration and temperature on equilibrium and to visualize how balance can be restored based on LeChâtelier’s Principle. Background Not all chemical reactions proceed to completion‚ that is‚ to give 100% yield of products. In fact‚ most chemical reactions are reversible

Essay #1 1. Mr. Sanchez makes an appointment to see his doctor for pain in his abdominal area. Tests and x-rays reveal kidney stones as well as bones with a moth-eaten appearance. Further questioning reveals a medical history of abnormal reflexes and weakness. What is the problem and what treatment would be recommended? Mr. Sanchez is suffering from hyperparathyroidism which is when the parathyroid glands secrete too much hormones. According to the medical website MedicineNet.com 85% of people
