PRACTICAL 2Materials required♦ Sunflower Seed OilFoam Bath which contains the following surfactants:Sodium Laureth SulphateCocamide DEAMethodTake 100ml of the foam bath and add the Sunflower Seed Oil in incremental amounts whilst stirring,until 2% has been added.Note any physical changes that occur during the addition and stirring process. Leave to stand for 3hours and again note any physical changes.Relate what mechanisms you think are occurring to the relevant outcomes that have been learnt in yoraw material, surfactant technology or surface chemistry units.Write a report noting your observations and the reasons for these changes that occur in this specificexperiment.

. Given the following drugs in a urine specimen: Cocaine alkaloid Secobarbital (a derivative of barbituric acid) Carisoprodol (a neutral drug) Devise an analytical flow chart that will be used to separate these substances from a urine specimen. The separation will be liquid extraction methods. Choose appropriate solvents and reagents based on the properties of the materials to be separated.
U Select all the statements that are true regarding the flowchart shown below. Mixture of three components in an ether solution. OH H₂N Benzoic Acid Ethyl 4-aminobenzoate 9-Fluorenone A Add 3 M NaOH Ether Layer Aqueous Layer Add 3 M HCI B с Ether Layer Aqueous Layer D E LL F Add 6 M NaOH A will only contain dissolved 9-fluorenone. D will contain dissolved 9-fluorenone. F will contain dissolved sodium benzoate. E will contain dissolved ethyl 4-aminobenzoate salt. C will contain solid ethyl 4-aminobenzoate. Add 6 M HCI
what would the overall reaction be for the recrystillzation of aspirin using 91% isopropanol to get pure aspirin?(drawn out) what would the mechanism be(if any)? More information provided below: You are removing salt, talc and other impurities to get pure aspirin. Recrystallization is a useful technique that can be used to purify solid organic compounds. Thistechnique involves the solubility of organic solids in various solvents. For recrystallization towork properly, the target compound must dissolve in a solvent when it is hot and not dissolvewhen it is cold. In this experiment you will isolate pure aspirin from aspirin tablets. Aspirin tabletscontain various salts and impurities in addition to aspirin. By using recrystallization, you will beable to remove the impurities and be left with pure aspirin.Sometimes pairs of solvents can used to produce better results. In this experiment, 91%isopropanol will be used to recrystallize aspirin. The 91% isopropanol contains 91%…

1) A polyester made from sebacic acid (CAS# 111-20-6) and 1,6-hexanediol (CAS# 629-11-8) has the molecular weight fractionation listed below. Calculate an appropriate average molecular weight for this polyester. Source: Batzer, H., Macromolecular Chemistry and Physics 5
A student use the same protocol as in the lab manual to extract 4 chloroanilline, benzoic acid and naphthalene. Below are the steps he took Step 1 - Dissolve all three in 15 ml ether and place in separatory funnel Step 2- Add 15 ml of hydrochloric acid and mix well Step 3 - Isolate the aqueous layer and add sodium hydroxide which resulted in a precipitate Step 4- Add 15 ml of sodium carbonate to the ether layer and mix Step 5- Isolate the aqueous layer and add hydrochloric acid, which resulted in a precipitate. Step 6- dry the ether layer and collect the solid that is left
Complete boxes in the flow chart. Draw the structure of the organic compound foundin each layer after adding 3M NaOH and extraction. Make sure to include any charges. Provide explanation on answers.
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?
Why does a solid form at the interface of the two solutions? PROCEDURESynthesis of NylonIn a small beaker dissolve ~ 0.5 mL of sebacoyl chloride in 12 mL of ether. In a smalltest tube get ~ 6 mL (~1/4 of a 6 “ test tube) of 1,6-diaminohexane solution in water.In order to form the good polymer fibers, it is best to not mix the solutions. Youshould try to layer one solution on top of the other. First pour the 1,6-diaminohexanesolution into a 100 mL beaker. Then slowly pour the sebacoyl chloride down the sideof the tilted beaker with minimal mixing. At this point you should see two distinctlayers with a white film at the interface. Hook the nylon which forms at the interfacewith a straightened paper clip and pull slowly straight up as high as possible. Thenwrap it around your large beaker and then continue to wind the polymer around tillthe reaction is complete. Rinse your polymer in DI water to remove any salts or acidthat may be present.Weigh your product and characterize it by…

The purpose of this experiment is to use both extraction and crystallization techniques to separate a solid mixture of organic compounds. You will receive a packet with 1 g of a unknown (pH is basic) amide solid sample which will contain three components, one from each group: Group 1 (~50% wt): ethyl 4-aminobenzoate, ortho-toluic acid, or benzoic acid Group 2 (~40% wt): fluorene, 1,4-dibromobenzene, benzil, benzoin Group 3 (~10% wt): fluorene, 1,4-dibromobenzene, benzil, benzoin (but not the same as Group 2 compound) Create a lab procedure that will allow you to successfully isolate, purify, and identify the two major (Group 1 and Group 2) components of the unknown amide sample. reagents that can be used are 1M HCl, 6M HCl, 1M NaOH, 6M NaOH, diethyl ether, and methylene chloride
