I'm supposed to do a lab tomorrow that involves creating a procedure where 2 of 3 components are to be separated and purified. The mixture is: 50% benzoin, 40% o-toluic acid and 10% 1,4-dibromobenzen. The reagents available are: NaOH, HCl, NaHCO3, saturated NaCl, diethyl ether, 95% ethanol, methanol, isopropyl alcohol, acetone, hexanes, toluene, methylene chloride, anhydrous sodium sulfate. Any suggestions on how to create a flow chart procedure for this?

I'm to develop a separation or purification scheme for the following mixtures:50% benzoic acid, 40% benzoin, 10% 1,4-dibromobenzene50% fluorene, 40% o-toluic acid, 10% 1,4-dibromobenzene50% ethyl 4-aminobenzoate, 40% benzoin, 10% 1,4-dibromobenzene50% ethyl 4-aminobenzoate, 40% benzil, 10% 1,4-dibromobenzene50% o-toluic acid, 40% fluorene, 10% 1,4-dibromobenzeneThe mixture is first dissolved in either diethyl ether or methylene chloride. And the available reagents are 1M NaOH, 6M NaOH, 1M HCl, 6M HCl, 1M NaHCO3, saturatedsodium chloride, diethyl ether, 95% ethanol, methanol, isopropyl alcohol, acetone, hexane, toluene,...
Organic Chemistry: Separation and Purification Scheme How do I isolate a mixture of 1,4-dibromobenzene from methyl chloride? Can I use the following reagents or is there a technique I should consider to separate these two? The reagents available are: 1M NaOH, 6M NaOH, 1M HCl, 6M HCl, 1M NaHCO3, saturated sodium chloride, diethyl ether, 95% ethanol, methanol, isopropyl aochol, acetone, hexane, toluene, methylene chloride, and granular anhydrous sulfate.
Given a mixture (0.5g total) with 50% 2-chlorobenzoic acid, 40% fluorene, and 10% 1,4-dibromobenzene, write a complete scheme/procedure for separation and purification. The following reagents will be available to use in the lab: 1M NaOH, 6M NaOH, 1M HCl, 6M HCl, 1M NaHCO3, saturated NaCl, diethyl ether, 95% ethanol, nethanol, isopropyl alcohol, acetone, hexane, toluene, methylene chloride, and anhydrous sodium sulfate. In addition, N2 gas will be available for evaporation and a vacuum will be available for filtration. Once you...
What are good recrystallizing agents for o-toluic acid, benzil, benzoin, p-aminoacetophenone, and phenanthrene? These are the available reagents: 1M NaOH, 6M NaOH, 1M HCl, 6M HCl, 1MNaHCO3, saturated NaCl solution, methyl t-butyl ether, ethanol, methanol, isopropylalcohol, acetone, hexane, methylene chloride, and anhydrous sodium sulfate
I have a mixture of three compounds and I want to separate them. The compounds are ethyl aminobenzoate (50%), benzoin (40%), and 1,4-dibromobenzene(10%). I started the experiment by dissolving the mixture in the methylene chloride, then I added HCl, so I got two layers, first one is aqueous layer that contain ethyl aminobenzoate, and the second one is organic layer that contain benzoin and 1,4-dibromobenzene. After that I add NaOH to aqueous layer and I got a solid, then I...
Please explain what is going on in this lab for STEP 3. what are some important factors? Multistep Synthesis Preparation of 4,4-Diphenyl-3-buten-2-one! This experiment illustrates se multistep synthesis, in which the the next. This process is very common iment illustrates several important concepts of organic synthesis. It is a synthesis, in which the product of one reaction becomes the starting material of This process is very common in industry and research, and demands careful to vields and techniques. The experiment...
1. Procedure A. Lithium 2,6-dimethylphenoxide. In a 300-ml. flask, equipped with a magnetic stirrer and a reflux condenser and flushed with nitrogen, are placed 150 ml. of toluene (freshly distilled from sodium), 1.40 g. (0.202 mole) of lithium metal (Note 1) and 25.0 g. (0.205 mole) of resublimed 2,6-dimethylphenol. The mixture is heated under reflux with stirring for 36 hours; a nitrogen atmosphere is maintained for the reflux period (Note 2). The condenser is replaced by a distillation head with...
Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
