Essays on Salicylic Acid

Introduction

Until recently, genetic foods have become popular for their ability to address many production and quality issues faced by natural/organic farming methods. Genetically modified crops are those whose genetic makeup has been improved to enhance the level of nutrients, resistance to diseases, increase yields, adaptability to climatic factors, and reduce the time of production (Ronald & Adamchak, 2008). It is different from the conventional breeding because genetic modification allows introduction of genes from any organism (animal and plants) in altering crops whereas breeding allows transfer of genes across related species only. On the other hand, organic farming is a natural ...

INFRARED SPECTROPHOTOMETRY AND ORGANIC CHEMISTRY

Infrared Spectrophotometry and Organic Chemistry Infrared (IF) Spectrophotometry is designed to determine the sample by measuring infrared radiation absorption of wavenumbers within the region of 4,000-400 cm-1 at different wavenumbers, as it passes through the sample. This technique employs the property that the IF absorption spectrum of the material is typical of its chemical structure. IR spectra are demonstrated in charts drawn via plotting on the abscissa and the absorbances or transmittances on the ordinate. Except when indicated, when the spectrum of the sample is the same in the intensity of absorption at a similar wavenumber to the ...

Introduction

Aspirin is one of the most commonly used drug in the world. The generic name is acetyl salicylic acid and the drug belongs to the group of non- steroidal anti-inflammatory medicines, which works by inhibiting the production of compounds in the body that cause pain, fever, inflammation, and blood clots (Koester, 1993). Aspirin is also a member of the salicylate family of compounds as it is synthesized from salicylic acid, which was discovered in Oxford (UK) by Edward stone in 1793 and first synthesized in the laboratory in 1897 by a German scientist, Felix Hoffmann of the Bayer company (Rinsema, 1999). ...

Introduction

Aspirin or acetylsalicylic acid refers to a salicylate drug that is usually used to relieve pains as an analgesic, as an antipyretic in the reduction of fever, as well as in fighting against inflammation. Aspirin falls in the category of weak acids and usually undergoes slow hydrolysis where one molecule of aspirin reacts with two hydroxide (OH-) ion. Different methods are applied in determining the amount of aspirin that is contained in an analgesic drug. These methods include back titration and fluorescence spectrophotometry. In fluorescence spectrophotometry, the molecules absorb the light energy supplied and then re-emit it. The emitted ...

Chemistry can be described as the branch of science concerned with the substances of which matter is composed, the investigation of their properties and reactions, and the use of such reactions to form new substances.

The Mechanisms and Synthesis of Aspirin

Aspirin is also known as acetylsalicylic acid (ASA). It is a salicylate drug used as an analgesic (something that relieves pain without producing anesthesia or loss of consciousness) for minor aches and pains, as an anti-inflammatory drug, and as an antipyretic to suppress fever. (Vane & Bottling 2000) The name “Salicylic acid’ was derived from salix, which is the willow family of plants. In ancient ...

Introduction

Aspirin is a commonly used drug. One of the properties of aspirin is that it is an analgesic, meaning that it relieves of pain. Aspirin is also an antipyretic drug meaning that it relieves on of fever. It also has anti-inflammatory properties meaning that if readily relieves swelling from tissues (Ahluwalia, Sunita & Adarsh 231). Salicylic acid has two functional groups. One of the functional groups is the phenolic group while the other functional group is carboxylic acid group. The presence of these two functional groups means that salicylic acid can undergo esterification in two different reactions. In one reaction, ...

[Class Name]

Aim/Objectives The aim of this experiment is to quantify the how much salicylic acid is collected between three different urine samples. A control sample, samples taken from subjects taking sodium bicarbonate to make the urine more basic, and samples from subjects taking ammonium chloride to make the urine more acidic. Using the assays provided, we will attempt to quantify the amount of salicylic present in the urine sample by the concentration and pH level since the ionization of salicylic acid is dependent on urinary pH.

Abstract/Introduction

Salicylic acid, a major component of Aspirin, is a compound used to ease ...

In the healthcare perspective, according to Gennaro et al. (2000), biochemical reactions are the chemical reactions involved in biochemical and cellular processes and particular actions of substances that affect these processes. Understanding biochemical reactions lead to the “understanding of the molecular bases of diseases”. The knowledge of receptor sites and metabolism (among other things) direct healthcare measures in efficient therapy management. Knowing normal cellular communication and metabolic pattern chemical reactions determine conditions that are abnormal in disease states. To Giese (2013), the scope of pharmaceutical reactions involve those of pharmaceutical biomolecules and biomolecule analogues and the chemical reactions involving ...

Lab Report on preparation of Esters by Esterification

Introduction The organic esters are characterized using their pleasant and fruity odors. Some of these odors include lead to fruits such as banana, pear, and orange to have their pleasant smelling. When carboxylic acid is mixed with an alcohol in the presence of a strong acid leads to the production of an ester. The strong acid is used as a catalyst and the general reaction is as below. The esterification reaction is a reversible reaction with the forward being referred to as esterification, while the reverse reaction hydrolysis. The general formula of an ester compound is as follows: The experiment aimed ...

Lab report on Preparation of Aspirin

Lab report on Preparation of Aspirin Introduction The chemical name for aspirin is the acetylsalicylic acid and is a drug that is used as an antipyretic. Aspirin reduces fever, relieves the pain and inflammation (Thomson Healthcare, 2012). The compound structure of acetylsalicylic acid has an ester group and is produced through an esterification reaction. Aspirin is synthesized through a reaction of salicylic acid with acetic acid using sulfuric acid as a catalyst. The reaction equation occurs as shown below. The experiment aimed at synthesizing aspirin, providing an opportunity to familiarize with vacuum filtration as well as melting point techniques. ...

PART-1 DILUTIONS

a) the technique of transferring an exact amount of liquid from one container to another a) The process of achieving a precise volume in one container while still being able to thoroughly mix the contents.

While pipetting, one should take care to avoid errors. The reading is taken by positioning the eye in correct point with the lower meniscus. Water is added little at a time to the volumetric flask to enhance proper mixing. Tap water is undesired since it has impurities plus ions, which interferes with the results of the experiment. When the water meniscus is almost fill line a “disposable pipette” ...
