Recrystallization of Benzoic Acid ABSTRACT The recrystallization of Benzoic Acid was performed to fully master the ability to purify a solid compound. This form of purification technique is especially important in chemical identification‚ where the melting point of the compound is taken to confirm its purity. In order to perform recrystallization a solubility test much be completed. Four solvents (95% Ethanol‚ Petroleum Ether‚ Acetone and distilled water) were used to identify which one is an ideal

Preparation of Ethers: 1. Preparation of symmetrical ethers from alcohols H2SO4 R O R + H2O 2ROH 2. Williamson Ether Synthesis R O Na - - + + + R’X R O R’ + NaX Ar O Na + RX Ar O R + NaX Involves a nucleophilic substitution reaction. Halide ion is displaced by the alkoxide or phenoxide ion. Gives best results when 1o alkyl halides are used. Mechanism is SN2. Alkoxides may be prepared by reacting an alcohol with NaH or by reacting an alcohol with Na metal

preparation of aspirin and oil of wintergreen | Introduction Organic compounds are those which contain carbon as well as a select other elements. An organic acid however‚ is an organic compound which contains acidic properties. An ester is an example of being a derivative of these organic acids. Esters can be prepared by the reaction of carboxylic acids and alcohols‚ with an inorganic acid used as a catalyst which is dubbed esterification. With o-hydrobenzoic acid‚ or salicylic acid‚ we are

Synthesis of Aspirin and Oil of Wintergreen INTRODUCTION: Synthesis and use of organic compounds is an extremely important area of modern chemistry. Approximately half of all chemists work with organic chemicals. In everyday life‚ many if not most of the chemicals you come in contact with are organic chemicals. Examples include drugs‚ synthetic fabrics‚ paints‚ plastics‚ etc. Synthesis of Aspirin and Methyl Salicylate. The two compounds we will be preparing‚ aspirin (acetylsalicylic acid) and oil

Lab 5 Acid/Base Extractions Introduction The purpose of this experiment is to separate either the organic base (amine) or organic acid (carboxylic acid) from a mixture that contains inorganic impurities (salt) by performing a liquid-liquid extraction and then taking a melting point. Key Experimental Details and Observations Our starting material‚ Compound B‚ was a fine white powder and weighed 0.535g. The final product was a shiny white sheet that resembled acrylic paint and weighed 0.109g

Title: Estimation of Ascorbic acid Aim: To determine the ascorbic acid content of canned apple and orange juice To determine the volume of canned juice necessary to provide 75mg of Vitamin C Introduction: For the estimation of ascorbic acid‚ the method used involved the titration of the ascorbic acid‚ in the presence of a redox indicator 2‚6-dichlorophenol-indophenol (DCPIP) which acts as both an oxidant so as to oxidise the ascorbic acid to dehydroascorbic acid‚ and it acts as an indicator
