Repeat with a second portion of acetone. Discard the acetone in the organic Wastes beaker (in the fume hood). The acetone readily dissolves the water removes it. The acetone is easily removed by gentle heating since acetone

The method used to separate the mixture is Distillation. Distillation is the process of separating liquid mixtures with components of varying degrees of volatility or significant differences in boiling point. The water and the acetone separated. The water and Acetone has different

The antioxidant activity was correlated with the amount of total phenolics present in the respective extracts in each assay. 50% acetone proved to be the most efficient solvent for extraction of antioxidants from mahua as the related extract contained the highest amount of phenolic compounds and also exhibited the strongest antioxidant capacity in all the assays used‚ while ethanol

Synthesis of Dibenzalacetone Leah Monroe May 15‚ 2003 Organic Chemistry Lab II Experiment performed on May 6 and 8‚ 2003 Abstract: The purpose of this experiment was to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. This was done by mixing the two reactants with NaOH and ethanol‚ then allowing the reaction to sit for thirty minutes. The crystals were then washed with water three times and recrystallized using ethanol. It was then characterized

shamefully seen in a Prius or Smart Car. One way to cheaply increase the fuel efficiency of your very own car is with the use of pure Acetone. Pure Acetone added to your gas tank at a ratio of three ounces of Acetone per ten gallons of gasoline can increase your fuel economy by 15 – 35 % depending on what you drive and what gasoline you use. This works because the Acetone changes the molecular structure of the gasoline so that it “stirs up” the molecules of the fuel to break surface tension‚ making the
