Experiment 2 Title: preparation of a halogenoalkane Objective: To synthesis 2-cholo-2-methylpropane by using corresponding alcohol and HCl(aq). The reaction is via SN1 of tertiary alcohol. Techniques: i) Distillation of the reactant and the product ii) Purification by separating funnel Theory: In the experiment‚ SN1 reaction take place‚ HCl is added to initiate the reaction. The R-OH attack the H+ with the lone pair on O. Then the R-O+H2 bond breaks the release a water molecule and

diabetes but no other major risk factors for heart disease probably should not be on low-dose aspirin therapy‚ new research suggests. The new recommendations are based on close examination of nine studies that found the risks of some aspirin side effects‚ such as stomach bleeding‚ should be better balanced against the possible benefits of using aspirin. The larger theme here is that use of low-dose aspirin to prevent heart attacks in people who have not already experienced one is probably not as efficacious

Aspirin Synthesis Introduction Out of all the pharmaceutical drugs in the worlds‚ aspirin is made the most. Any potential pharmacist must be familiar with synthesizing the drug. The goal of this lab is to synthesize as much pure aspirin as possible. The reactants‚ acetyl anhydride and salicylic acid‚ must react in phosphoric acid. With phosphoric acid as a catalyst‚ the reaction yields aspirin and acetic acid. The equation for the reaction is as follows: “(CH3CO)2O + HOC6H4COOH □(→┴yields ) CH3CO2C6H4CO2H

to synthesise acetylsalicylic acid (aspirin) by creating a reaction between acetic anhydride and salicylic acid. This was be accomplished through the use of recrystallization. Acetic anhydride and salicylic acid are mixed together‚ and then acidified by the addition of a few drops of concentrated sulfuric acid‚ which catalyzed the reaction. The percent yield is calculated to determine the effectiveness of the reaction in preparing the desired product (aspirin). The limiting reactant of the equation

Chewable aspirin can be chewed‚ crushed or swallowed whole but after being consumed the consumer should drink full glass of water. There are many uses for Aspirin. Prescription Aspirin is used to relieve symptoms of rheumatoid arthritis‚ arthritis caused by the swelling of the lining of joints‚ osteoarthritis‚ arthritis caused by breakdown of lining of joints‚ systemic lupus erythematosus‚ the immune system attacks joints and organs‚ and can cause pain/swelling.
