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
Ethanol and methanol are good recrystallising agents.the process of recrystllisation involves dissolution of solid in appropriate solvent in elevated temperature.

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.
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?
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...
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...
You will have to perform all the steps necessary to separate your assigned compound from its impurities and prove through analysis (melting point, boiling point (if applicable), NMR, IR and Rf-values (if applicable)) that your compound is pure: An organic student was trying to purify acetaminophen from Advil but the extraction using dichloromethane yielded a mixture of caffeine and acetaminophen. Purify the acetaminophen. Provide data to show that your compound is pure. Materials Available to you: Solvents: acetone, ethanol, methanol,...
please answer all these questions, thank you. CHEM 242L Exp. 4 Report/ Synthesis of Oil of Wintergreen Name Score: 20 1) Assess the effectiveness of the experiment and your technique by A) reporting the yield of each step in grams and percent as well as the overall percent yield (What is "overall percent yield?).

What is the theoretical yield (in grams) and percent yield of your triphenylmethanol product in this experiment? (Weight of triphenylmethanol: 0.060g) BACKGROUND AND THEORY The Grignard reaction was one of the first organometallic reactions discovered and is still one of the most useful synthetically. By reacting an organohalide (usually a bromide) with magnesium in ethereal solvent, carbon becomes a nucleophile. Grignard reagents are the starting points for the syntheses of many alkanes, primary, secondary, and tertiary alcohols, alkenes, and carboxylic...
