Ethyne Glycol Research Paper

This experiment involved three steps: synthesis of aspirin, isolation and purification, and the estimation of purity of the final product. The synthesis involved the reaction of salicylic acid and acetic anhydride in the presence of a catalyst, phosphoric acid, H3PO4. When the aspirin was prepared, it was isolated and filtered. The percentage yield of the synthesis was calculated to be 78.42%. The experimental melting point range of aspirin was determined to be 122 -132°C. Due to its wide range, and lower value than that of the theoretical melting point of 136°C, it was

A common road salt, magnesium chloride, was analyzed in the lab to test its effectiveness as a road salt. The Van’t Hoff factor of the salt and the enthalpy of dissolution when dissolved in pure water were experimentally tested to evaluate its many characteristics as a deicer. To determine the Van’t Hoff factor, the difference of temperatures of freezing water

The goal of this experiment was to determine the empirical formula for a hydrate of magnesium sulfate and water. The technique that was used was measure the mass of the hydrate and then apply heat to evaporate the water. Then determine the mass of water that was in the hydrate and the mass of the remaining magnesium sulfate. The equation for the hydrate is determined by calculating the mole to mole ratio of the water and the anhydrous. The resulting formula will be formated as: MgSO4*_H2O

Acetaminophen, [uh-see-tuh-min-uh-fuh n]; is a name for a drug, which is fairly difficult to pronounce. Thankfully though we have several medicines to make it simpler to say. The over the counter drugs contain but are not limited to, APAP, Aspirin Free Pain Relief, Children's Pain Reliever, Feverall, Mapap, Meda, Tempra, Tylenol, and Uni-Ace. Though the most commonly known product is probably, Tylenol. Tylenol can be prescribed for relief of mild pain and reduction of fever. Though it is mainly prescribed for that, it can be used for a variety of things. For example, short term pain during pregnancy, colds, muscle aches, arthritis, backache, and toothaches.

The production of aspirin begins salicylic acid which has been derived from the active site of salicin found in willow bark. This is done through multi-step process where substrates of salicin are converted into more basic products such as salicylic acid. Salicylic acid cannot be consumed by itself due to the fact that it is bitter and irritates the stomach causing side effects such as nausea and internal bleeding within the stomach. This is due to the fact that salicylic acid exists in protonated form in the stomach; therefore, the pH of the salicylic acid is low, thus affecting the lining of the stomach. Therefore, to stabilise salicylic acid, it is synthesized into acetylsalicylic acid also known as aspirin. Acetylsalicylic acid is not pronated in the stomach and thus, the pH of acetylsalicylic acid is not as low compared to salicylic acid, thus it does not affect the lining of the stomach as much compared to salicylic acid.

The periodic table has 118 elements. The compound we are going to focus on is acetaminophen. What is the drug acetaminophen? It is an over-the-counter drug that serves as a painkiller and a fever reducer. It is used to treat various conditions such as muscle aches, backache, toothaches, headaches, and arthritis. Although it is considered an analgesic because it is a pain reliever, it has no anti-inflammatory properties. Also, because it contains no anti-inflammatory properties, it is not a member of the non-steroidal anti-inflammatory drugs, also known as NSAIDs.

The first compound they started off with was NaCl which is table salt. They noticed that table salt alone wasn't doing a great job so they tried CHKO2, which is the formula for potassium formate. Potassium formate is an ionic compound which is a chemical compound in which ions are held together by electrostatic forces termed ionic bonding. After they created this compound they liked the results so they didn’t need another compound. As you can see they used chemical compounds by taking single elements and putting them together to make a new substance to de-ice the roads.

Suppose we make a solution by mixing water and ethylene glycol (C2H6O2, the main ingredient in antifreeze).

Aspirin: A mainstay at pharmacies ever since its invention, aspirin is great for fevers, colds, and headaches. It even reduces the risk of heart attacks, but like ibuprofen, it's hard on the stomach.

As the acid was being added, the mixture was being stirred over a stir plate. Once completed, the reaction mixture was poured from the round bottom flask into a 500 mL separatory funnel and its top (organic) layer was extracted into another beaker. The bottom (aqueous) layer was placed back into the funnel and extracted twice with 50.0 mL of ethyl ether each. The newly extracted layers were combined and dried over magnesium sulfate (MgSO4). The dried solution was the decanted into a beaker to remove the MgSO4 salts and the product solution was collected via Buchner vacuum filtration. The resulting product was transferred into an Erlenmeyer flask with an inverted beaker on top and stored in a drawer.

of prostaglandin E2, which lessen the hypothalamic target point to reduce fever, and creating active the descending inhibitory serotonergic pathways to produce analgesia. Even though acetaminophen have similarities with the analgesic and antipyretic properties of other COX inhibitors like the aspirin and the non-steroidal anti-inflammatory drugs (NSAIDs), still it does not possess considerable anti-inflammatory properties. Contrary to aspirin, acetaminophens do not hinder thromboxane and, as such, aggregation of platelet does not change.

Epsom Salt is simply magnesium sulfate (MgSO4) in a heptahydrate form (hepta = 7, hydrate = H20). They are widely used to sooth and hasten healing of cuts, scrapes, bruises and sore muscles when used as a soaking agent in a bath. Though this salt has many other uses in agriculture, medical, and chemical arenas, we will be focusing on how it can help bodybuilders.

Anti-inflammatory properties — Swedish research has found that THCA inhibits COX1 enzymes by over 50 percent. Plus, COX2 enzymes are inhibited by over 30 percent. COX1 and COX2 enzymes produce inflammatory substances, known as prostaglandins, from omega-6 fatty acids. Aspirin works in the same way. https://www.ncbi.nlm.nih.gov/pubmed/21532172

Antifreeze is a coolant solution composed of an ethylene based product that contains a rust inhibitor. Since it is a “dual performance product,” antifreeze can do two main things: stop your car engine from freezing or stop the radiator from overheating. The rust inhibitor that is included in the solution prevents rusting or corrosion in parts of all engines. Without antifreeze, we would not be able to drive on extremely hot or cold days. It does this by lowering the boiling point of water. The product can lower the boiling point of water by This product was created by NASA to be used for automobiles, generators, and diesel engines to reduce the risk of complications in machinery. There are many other benefits of using antifreeze.
