Separation Of Excedrin

Recommended: Synthesis and extraction of aspirin lab report
This paper describes the separation and isolation of the three active components of Excedrin. The three components of aspirin, acetaminophen, and caffeine were separated using the technique of acid-base extraction with K2HPO4 and KOH being the bases and HCl as the acid. Distillation was also performed on the ether layer to extract the caffeine. One week later, crystals from the K2HPO4 and KOH solutions were acquired via vacuum filtration. Due to the ether evaporating, crystals from the ether did not need to be filtered. Thin Layer Chromatography (TLC) was then performed on the K2HPO4 crystals, the KOH crystals, the ether crystals, the K2HPO4 liquid solution, and the KOH solution. The TLC determined the K2HPO4 crystals as aspirin, the KOH crystals

Separation Challenge Lab Report
1157 Words | 3 PagesThe Separation Challenge is an experiment involving the use of background knowledge of mixtures, properties of matter, and creativity in order to find a solution to separate three different substances layered on top of each other within a container. The experiment required a matter of coming up with a solid and thought out procedure to successfully separate the three substances individually within an amount of time using various lab materials and technology accessible at the time.
Summary Of Phensuprin
1470 Words | 3 PagesThe purpose of this experiment was to learn and preform an acid-base extraction technique to separate organic compounds successfully and obtaining amounts of each component in the mixture. In this experiment, the separation will be done by separatory funnel preforming on two liquids that are immiscible from two layers when added together. The individual components of Phensuprin (Acetylsalicylic acid, Acetanilide, and Sucrose as a filler) was separated based upon their solubility and reactivity, and the amount of each component in the mixture was obtained. Also, the purity of each component will be determined by the melting point of the component.

Nano Thermal Analysis of Pharmaceutical Materials
1158 Words | 3 PagesThe analysis is therefore one of the most effective methods of ensuring that each drug being prescribed to patients is safe. It also ensures that all drug components are understood in terms of their structure and chemical behavior. This understanding is very important in the manufacture of drugs and other pharmaceutical products.
Caffeine Extraction Experiment
1054 Words | 3 PagesThe experiment was conducted in three parts: Part A of the experiment consisted of extracting caffeine from an aqueous solution; Part B consisted of using three different compounds: benzoic acid, succinic acid, and sodium benzoate; and the last part of the experiment consisted of using a solid neutral compound with an acid or base impurity.
Deciphering Mixture Components Through Separation Techniques
1876 Words | 4 PagesBased on our observations during the separation techniques and some speculation, we were able to identify eight components of our mixture: graphite from the filtration residue, Epsom salt from crystallization, water and acetic acid through distillation, red and orange dye, iron metal, marble chips, and sand.
A Summary Of Acid-Base Extraction To Isolate Eugenol
783 Words | 2 PagesPerforming this experiment, we used the technique called Acid-Base extraction to isolate Eugenol, which is one of the main ingredients of clove oil. Acid-Base extraction is the most efficient method for isolating organic component; it is efficient because it purifies the acid and base mixture based on their chemical identities. We have seen throughout this experiment that acid and base play an important role, when it comes to solubility in water. Our basic knowledge of acid and base is acid is a proton donor and base is a proton acceptor. This ideology helps us to understand why organic compounds are not soluble in water. When compounds tend to be insoluble, we have to use acid and base reaction, to change its solubility. The changes that occurred
The History and Uses of Asprin
847 Words | 2 PagesMost people know Aspirin as a pill to take when they have a headache or some other ailment. There’s much more to Aspirin than most people know about. This report will explain the chemical properties of Aspirin as well as what the uses are, the history of the chemical, and the discovery of the molecule.
LAB Elimination Reactions Tested
1551 Words | 4 PagesPurpose/Introduction: In this experiment, four elimination reactions were compared and contrasted under acidic (H2SO4) and basic (KOC(CO3)3) conditions. Acid-catalyzed dehydration was done on 2-butanol and 1-butanol; a 2o and 1o alcohol, respectively. The base-induced dehydrobromination was performed on 2-bromobutane and 1-bromobutane isomeric halides. The stereochemistry and regiochemistry of the four reactions were analyzed by gas chromatography (GC) to determine product distribution (assuming that the amount of each product in the gas mixture is proportional to the area under its complementary GC peak).
Aspirin Is Bad
654 Words | 2 PagesAspirin contains the substance acetylsalicylic acid (ASA), which can relieve inflammation, fever, pain, and known as a “blood thinner”. Aspirin was not officially trademarked until March 6, 1899 when the Imperial Office of Berlin made it official. It has been used for the last 110 years, but its natural form, salicylic acid has been around for thousands by Egyptians, Greeks, and Romans. Aspirin is available in over 80 countries and known as the best non-prescription drug. The most common use of aspirin is to cure headaches and use it as a pain reliever, but aspirin is known to prevent heart attack and strokes. It was first proposed in 1940, but wasn’t confirmed until 1970 when doctors would recommend taking aspirin daily [1].
Paracetamol Lab Report
671 Words | 2 PagesThe conical vial was placed in a small beaker and allowed to cool to room temperature. The mixture was Cooled thoroughly in an ice bath for 15-20 minutes and crystals collected by vacuum filtration on a Hirsch funnel. The vial was rinsed with about 5 mL of ice water and transferred into to the Hirsch funnel and again washed with two additional 5mL portions of ice water. Crystals were dried for 5-10 minutes by allowing air to be drawn through them while they remained on the Hirsch funnel. The product was transferred to a watch glass plate and allow the crystals to dry in air. Crude acetaminophen product was weighed and set aside a small sample for a melting point determination and a color comparison after the next step. Calculation of the percentage yield of crude acetaminophen (MW = 151.2). was done and recorded in the lab notebook.

Analgesics
539 Words | 2 Pages·Aspirin (salicylic acid acetate) is an anti-inflammatory (decreases swelling and inflammation), anti-pyretic (fever reducing), and anti-platelet (decreases platelets in the body to thin blood). Many heart treatment patients take an aspirin a day to prevent blood clotting. However, if aspirin is taken in large quantities over long periods of time, it may cause gastric ulcers or other internal damage. The molecular formula of aspirin is C9H8O4. Some examples of Aspirin are Bayer, Ecotrin, and Aspergum.
