Lab 3 - Extraction Objective In this experiment, you will separate the components of a commercial headache powder via an extractive process. This separation will be accomplished by taking advantage of the fact that each component contains different functional groups which will react differently when treated with a specific reagent.
The insoluble sucrose can be filtered out if Panacetin is dissolved completely in dichloromethane by gravity filtration or centrifugation leaving the soluble aspirin, acetanilide and phenacetin in the solution.
The experiment involved the separation of the unknown from the Panacetin by first isolating the sucrose and the aspirin. This process was done by starting with three grams of Panacetin and adding dichloromethane to dissolve and then separating the sucrose by filter-gravity filtration.
Using your understanding of these properties, separation of a mixture containing a carboxylic acid, an amine, and a neutral compound can be carried out via sequential acid and base extractions. The precipitates will be collected and characterized by melting temperature analysis.
Separation of the two layers results in the separation of the two compounds. The extent to which an acid-base reaction proceeds to completion depends upon the relative acidity of …

The label on the suspected bottle lists the ingredients per tablet as aspirin (200 mg), acetaminophen (250 mg), and sucrose (50 mg). The sucrose is an inactive ingredient used to make the tablets more palatable to children.
Panacetin tablets are known to contain aspirin, acetaminophen, and sucrose; therefore, the tablets tested, containing aspirin and sucrose, are thought to contain an unknown of something similar to that of acetaminophen such as acetanilide or phenacetin.

Sample Calculations for Panacetin. Students are asked to do several calculations related to the Panacetin painkiller experiment. The following example calculations should be helpful. (Your weights may not match the weights in the example.) Assuming a student isolated 0.5 g sucrose, 0.5 g aspirin, and 1.0 g of crude unkn, here's what the calculations would look like:
1 Aspirin is the common name for the compound acetylsalicylic acid, widely used as a fever reducer and as a pain killer. Salicylic acid, whose name comes from Salix, the willow family of plants, was derived from willow bark extracts.
Sucrose is one of the oldest sweetening agents and the most used caloric sweetener, both for home and commercial use. Also known as common table sugar, brown sugar, liquid sugar, sugar, table sugar, refined sugar, or white sugar, it consists of one unit of glucose plus one of fructose linked together by α-(1→2) glycosidic bond.
Aspirin reacts with bases (NaOH) to form a salt (sodium acetylsalicylate) that is insoluble in DCM; relatively soluble in water --> if first convert Aspirin (after Sucrose removal), will separate Aspirin (salt) from rest of drug mixture (due to insoluble in DCM) and can then convert salt back into Aspirin
A flow chart is often used to illustrate the steps involved in the separation of a mixture. In a flow chart, the substances in the mixture are listed inside boxes and are connected by arrows.
Acetaminophen is a weaker acid than carbonic acid, but aspirin is a stronger acid than carbonic acid. Prepare a flowchart showing a procedure for separating a mixture of sucrose, aspirin…
Prof. Gabriela Weaver, Special Assistant to the Provost for Educational Initiatives, was a recent guest panelist on the 22News program InFocus which discussed STEM (Science, Technology, Engineering, and Math) education programs in higher education.

The percent composition that was listed in the book was sucrose: 8-12%, aspirin: 35-45%, and the unknown: 45-55%. The most likely problem for the sucrose not being in the ideal percentage was because of the presence of water.
Once you have separated the sucrose and aspirin from the unknown, you will. At a constant boiling temperature and can not be separated by distillation. The separation process itself encourages mastery of several laboratory.

Sep 10, 2010· I am at my wit's end on this one and would really appreciate it if someone could explain this question and how to solve it to me: Acetaminophen is a weaker acid than carbonic acid (H2CO3), but aspirin is a stronger acid than carbonic acid. Prepare a flow diagram showing a procedure for separating a mixture of sucrose, aspirin, and acetaminophen.
