In our ecocolumn many changes occurred over the several week course we were observing and collecting data on the three chambers. Aquatic and Decomposition quickly turned septic while terrestrial experienced plant growth. Overall the health of the ecosystem was very poor due to the severe changes in the aquatic chamber. Terrestrial In the Terrestrial camber of our ecocolumn‚ several changes happened over time. The clover seeds planted at the beginning had a rapid growth rate. At one point our chamber

Preparation and melting point of Aspirin Aspirin is a painkilling drug and is produced worldwide to reduce and stop pain. Aspirin is made up of ehtanoylation of 2-hydroxbenzenecarboxylic acid in a presence of phosphoric acid. AIM: The aim of the experiment is to prepare and produce aspirin as pure as possible. I will do this threw preparing the aspirin and purifying the product threw recrystallization. I will then obtain a melting point of my product to get an estimate of its purity. By the end

Prelab 5B Macrocyclic Synthesis OBJECTIVE: The objective this week is to produce Tetraphenylporphyrin and its metal complex. This will be carried out by condensation of 4 equivalents of Benzaldehyde and pyyrole in the presence of propanoic acid. The product will undergo UV/Visible Spectrum tests to determine its lambda max. The lambda max will show us the relationship between a conjugated system and the visible spectrum. PROCEDURE: Step 1: preparation of meso-tetraphenylporphyrin (TPP)

Purification of Acetanilide by Recrystallization Method Dupaya‚ Julian Victor M. Estacio‚ Jerwin Caesar A. Farnacio‚ Rebecca Ruth Gabito‚ Jose Luis F. Gallo‚ Cian Carlo M. Galvez‚ Joshua M. Group no.4‚ 2D-Medical Technology‚ Faculty of Pharmacy‚ University of Santo Tomas ABSTRACT Recrystallization is a method for purifying solid organic compounds. The process is dissolving the solid to be purified in a hot solvent and cooling the solution slowly‚ this allows impurities with different

Soluble aspirin tablets Adult dosage: To treat pain or fever in adults‚ the recommended dose is 325 mg to 650 mg every 4 to 6 hours as needed. The maximum daily dose is 4‚000 mg‚ unless otherwise directed by your doctor. For adults with conditions caused by inflammation such as rheumatoid arthritis‚the usual dose is 975 mg 4 to 6 times daily on a regular basis. Sometimes‚ higher doses may be used. To treat migraine headache pain‚ the recommended adult dose is 1‚000 mg at the onset of pain or

Once the aspirin is prepared‚ it is isolated from the reaction solution and then it is purified. The aspirin is insoluble in cold water‚ and it is isolated by filtering the chilled reaction solution. Purification is essential to remove any unreacted salicylic acid and acetic anhydride as well as the acetic acid product and phosphoric acid. Acetic anhydride is caused to decompose by the addition of water once the formation of aspirin is complete. C4H6O3 (Acetic anhydride) + H2O (Water) ------------------------->
