Seperating and extracting the components of panacetin aim: to measure, analyze, through extraction and seperation of the components of chemical, panacetin, which will conclude whether the label attached measures adequate amounts and contains us grade safe contents to which the drug, panacetin, is originally produced by extraction of the. In lab 2 you had separated a mixture of panacetin into separate pure compounds and determined the composition of each component in the drug in this lab you will be identifying the unknown component (acetanilide or phenacetin) by melting point analysis.
Extraction and evaporation: separating the components of panacetin panacetin is typically made up of sucrose, aspirin, and acetaminophen, but the third component in this experiment is unknown the unknown component is suspected to be a chemical relative of acetaminophen, either acetanilide or phenacetin. Introduction panacetin is a common analgesic and antipyretic drug derived from aspirin, acetaminophen, and sucrose the given sample is known to contain 8-12% sucrose, 35-45% aspirin, and the remaining 45-55% is an unknown component. Reality sandwich is a magazine of ideas for the transformational community we cover subjects like shamanism, non-local consciousness, visionary art, alternative economics, psychedelics, permaculture, transformational festivals, meditation, democratic engagement, near death experiences, and tantra.

Shot by paul j ramsey, media resources, eastern kentucky university. Physical separation techniques introduction when two or more substances, that do not react chemically, are blended together, the result is a mixture in which each component retains its individual identity and properties the separation of the components of a mixture is a problem frequently encountered in chemistry the basis of the separation. Separation of the components using dcm was first employed this step separated sucrose from the rest of the mixture the liquid portion was then combined with nahco3 creating two separate layers, an aqueous top layer and an organic bottom layer. 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 05 g sucrose, 05 g aspirin, and 10 g of crude unkn, here’s what the calculations would look like.
