- If 80% of a desired compound is extracted into the organic phase in each step (leaving 20% in the aqueous layer), how many extractions are necessary to ensure that at least 99% of the compound has been recovered in the organic phase? 1 extraction 2 extractions 3 extractions 4 extractionsWhich is the more effective extraction technique, single or multiple extractions? Explain.A mixture is made up of low molecular weight carboxylic acid, alcohol and ester. What one step procedure can you use to extract the ester component from the mixture? Describe the process briefly
- methyl alcohol and ethyl alcohol are poor extraction solvent. why?3 Draw a flow chart to shows the strategy for separation of three compounds: Phenanthrene and 4-Aminoacetophenone and 1,4-Dibromobenzen and dissolve mixture is Diethyl ether. add NaOH (1M) and (6M) to the aqueous layer and ether layer..Suppose you have an organic sample X that is somewhat soluble in water, even though it issomewhat more soluble in dichloromethane or ether solvents. But if you do a singleextraction, you get only 60% of your material to transfer from the water to the organic layer.How many “washes” would it take to extract over 90% of your organic material extracted fromthe water layer?
