-------------------------------------------------------------------------------- With Calcium Hypochlorite and Acetone When chlorine is passed into boiling alcohol‚ both chlorination of the methyl group and oxidation of the primary alcohol group to an aldehyde occur‚ giving trichloro-acetaldehyde or chloral: When chloral is treated with caustic alkali‚ fission of the C-C linkage occurs‚ giving chloroform and a formate. Acetaldehyde and also many ketones‚ such as acetone‚ containing the CH3CO- group behave similarly when treated with calcium

molten polystyrene into Styrofoam through the construction of a porous cellular structure. The organic compound (CH3)2CO‚ or acetone‚ is a translucent flammable liquid that exhibits a high degree of solvency. Many compounds are soluble when exposed to acetone. A Styrofoam and acetone experiment can determine if Styrofoam will dissolve when placed inside a container of acetone. Starch is the major component of flour. Starch exists in tiny granules‚ which swell and break when boiled in water. This

mixture of hexane and acetone was determined to best solvent for this extraction. Knowing this add one mL of the pure hexane and one mL of the pure acetone to the mortar. Grind the contents until the cell walls have been adequately broken. Transfer the mixture to a centrifuge tube to separate the sample into layers‚ to help remove the water. Once the sample is finished spinning extract the organic layer and place in a test tube. TLC: To determine which mixture acetone and hexane is the best

substitution reaction. Procedure: 1. Sodium Iodide in Acetone. Acetone‚ with a dielectric constant of 21‚ is a relatively nonpolar solvent that will readily dissolve sodium iodide. The iodide ion is an excellent nucleophile‚ and the nonpolar solvent‚ acetone‚ favors the Sn2 reactions; it does not favor ionization of the alkyl halide. The extent of reaction can be observed because sodium bromide and sodium chloride are not soluble in acetone and precipitate from solution if reaction occurs. 2. Ethanolic

phytochemical and biological analysis of Paris polyphylla (PP). Crude Chloroform/Methanol (1:1) extraction performed on the rhizomes of Paris polyphylla collected from himalayan region of Nepal was followed by fractionaion process using petroleum ether and acetone for the separation of extract based on their polarity. The extract was run through Thin Layer Chromatography and the test confirmed the presence of polar and Non-polar compounds based on their mobility. Phytochemical screening was performed and presence

capillary Tube: Before using the capillary tube in an experiment using acetone‚ students are advised to clean the inside of the tube. Prepare a weak solution of detergent. Use the Hirschman pipette to fill the tube with the solution. Tapping the of side of the tube may be necessary if the solution is trapped and does not flow down. Turn the tube upside-down and shake. Empty the tube. Repeat steps 2 to 3 with acetone. The tube is now ready for student experiment. General Shut-down

The Effect of Solvent Exposure and Temperature on Beet Cell Membrane Integrity Introduction: • Cell membranes are vital to proper cellular function • Cell membranes consist of a lipid bilayer made up of phospholipids • Phospholipids are amphipathic molecules meaning they have a dual nature in that they show both hydrophilic (water-loving) and hydrophobic (water-fearing) properties • The amphipathic nature of phospholipids causes them to spontaneously form bilayers in water
