Experiment conducted: 05/02/2009 Date Report Written: 08/02/2009 Synthesis of Acetyl salicylic acid (Aspirin) Abstract Introduction: The following report contains information on how to produce aspirin. The experiment has been carried out on a small laboratory scale. The experiment starts by combining such chemicals such as salicylic acid and acetic anhydride. The synthesis of aspirin is classified as an esterification reaction. This is a substitution reaction where the alcohol group from

Synthesis of Aspirin and Oil of Wintergreen Janelle Alyssa P. Prudente De La Salle University-Dasmariñas Dasmariñas City‚ Cavite‚ Philippines ABSTRACT In this experiment‚ acetylsalicylic acid commonly known as aspirin and methyl salicylate‚ commonly known as oil of wintergreen‚ was synthesized from salicylic acid. This study will show that it is possible to show two very different organic compounds from the same common starting material. For the synthesis of aspirin‚ salicylic acid

One disadvantage is the concept of this low cost lightweight laptop has a lack of awareness of how the laptop would educate children and market problem. OLPC’s mission is to help children for learning and developing knowledge throughout the low cost laptop and it calls an education project (LOPC mission). The point is that OLPC needs to educate foreign countries and their governments of education about the feature of this laptop works‚ and most importantly‚ what are the key essential techniques of

Constituent of “Panacetin” Recrystallization& Melting-Point Measurement Organic Chemistry Lab Introduction: Panacetin purportedly includes sucrose‚ aspirin‚ and acetaminophen. However‚ the accuracy of Panacetin’s contents has been called into question by the Association for Safe Pharmaceuticals. Therefore‚ the lab must discover the accuracy of the ingredients listed on Panacetin’s label. The unknown in this experiment is presumed to be something

Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that

Investigation and Preparation of Esterification Lab Introduction Esters are classified as organic compounds commonly derived from carboxylic acids. They are compounded from the reaction of a carboxylic acid with an alcohol in the presence of a strong acid to be used as a catalyst. The formula that represents an ester is R-COO-R where both Rs’ are alkyl groups‚ one which is bonded to an oxygen‚ and the other to a carbon which is double bonded to 1 oxygen and single bonded to the other. Esters

of the specialized underlying structures of these life-forms. In order for us to appreciate these special adaptation‚ we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab‚ we will determine the effects of hypertonic‚ isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell’s placed in hypertonic solution it shrivels; a plant cell on the other hand undergoes plasmolysis. When an animal
