Salicylic acid

types of esters by the process of dehydration synthesis using an alcohol with an acid. Introduction The process by which esters are formed is a reversible reaction called esterification. They are formed when alcohols react with carboxylic acids in the presence of hydrochloric acid or sulfuric acid. This reaction is known as a condensation reaction. In the reaction above, the hydroxyl group (-OH) in the carboxylic acid is replaced by the alkoxy group (-R*O) of the alcohol yielding an ester and water

In an esterification reaction, a carboxylic acid reacts with an alcohol. The synthesis of aspirin is an esterification reaction. Initially, the proton, i.e. the hydrogen ion, from the acid attacks the acetic anhydride and attaches itself on a double bond oxygen. This makes the compound more electrophilic, meaning that it has a higher affinity for electrons. This is what sets off the reaction. The salicylic acid then acts as an alcohol and attaches its OH group onto a carbon on

of recrystallised compound. 2. INTRODUCTION 2.1 Definition of aspirin. “Aspirin is a white, crystalline compound, CH3COOC6H4COOH, derived from salicylic acid” and is commonly use in tablet form to relieve pain, reduce fever and inflammation. It is also use as an anti platelet agent (Yahoo! Inc, 2009). The chemical name of aspirin is acetylsalicylic acid (Aspirin.foundation 2010). It has analgesic, antipyretic, and anti-inflammatory

Organic chemistry is the complexity of natural compounds. It is applied to the production of mundane objects that include: plastics, polymers, soaps, detergents and drugs. Such compounds of organic chemistry involve the identification, modelling, chemical reactions and synthesis – it initiates the concept of design implemented in organic compounds (Helmenstine A, 2014). An example of an organic compound is the product of organic drugs in which are manipulated behind the chemistry of its design. A

Introduction: Heartburn is generally caused by imbalanced gastric juices/acids. Antacids are a type of medication, which corrects the pH balance in your stomach. A pH scale is a scale that ranges from 0-14, with 0 being the most acidic, 7 being neutral, and 14 being most basic. There are many types of antacids, such as sodium bicarbonate (contains baking soda), calcium carbonate, there is also aluminum and magnesium based antacids. A combination of aluminum and magnesium based antacids also

Glycolic acid helps remove the epidermal layers which enables the ingrown hair to find its way out above the skin layer. In addition, glycolic acid has antibacterial properties preventing any further infections due to pathogenic bacteria. Glycolic peels are also available to enable treatment of razor bumps on legs. It is a convenient way to get rid of razor burns as the application is simple and the results are swift. In addition, a glycolic acid peel will enhance the tone of the skin.  Salicylic acid

!!!Carboxylic Acids: Structural Formula and Properties Carboxylic acids are among us - they are used in manufacturing common items we have at home, like soap, vinegar and aspirin. There are so many commercial products that we use that are manufactured using carboxylic acids. So, what exactly are carboxylic acids? __Carboxylic acids__ are a classification of organic compounds. They are organic because they contain carbon (C) in their chemical structure. [{Image src= 'carboxylicacidspicture1.png

hydrogen in the compound's carboxyl group is replaced with a hydrocarbon group. Esters are derived from carboxylic acids and (usually) an alcohol (Helmensine A, 2017). The reaction required to produce an ester is called esterification. Esterification is the reaction in which a Carboxylic acid combines with an alcohol in the presence of a catalyst (commonly concentrated sulphuric acid) to form an ester (Esterification, 2017). This is an example of a general class of reactions called condensations
