    Synthesis of Methyl Stearate The purpose of this lab was the convert liquid methyl oleate to solid methyl stearate by catalytic hydrogenation. Firstly‚ we produced hydrogen gas using solid mossy zinc and sulfuric acid. Using the hydrogen produced in the previous reaction‚ we were able to convert the liquid methyl oleate to solid crystals of methyl stearate. A mineral oil was also used to bubbler was used to maintain the hydrogen pressure slightly above the atmospheric pressure and to prevent back-diffusion

    For the first part of the experiment‚ it began by weighing 4.0ml of methyl salicylate into a flask—a stir bar was added. While stirring‚ 40ml of 6M sodium hydroxide was added and the solution was heated and boiled for about 15 minutes. After the 15 minutes‚ a bit of water was used to wash down the sides of the flask and the solution was cooled. It was boiled for another 15 minutes‚ after this the solution was cooled for 5 minutes in an ice water bath. While the flaks was in the ice bath‚ 50ml of

    Nitration of Naphthalene Wed 2/25/2015 Lab report # 1 Abstract: The purpose of this experiment was to nitrate naphthalene with nitronium ion‚ which is formed at low concentration from a reaction of nitric acid and sulfuric acid. The percent yield from the experiment was 54.4% of the product‚ and the melting point of the possible results were 59 °C for 1-nitronaphthalene‚ and 78°C for 2-nitronaphthalene. Introduction: Polynuclear aromatic hydrocarbons such as naphthalene can be nitrated

    substitution reaction is the attack of a benzene ring on an electrophilic species resulting in the substitution of a proton with a functional group. The electrophilic aromatic substitution reaction nitration is used to nitrate methyl benzoate and acetanilide with a nitronium ion. Crystallization was used to purify the product. The melting point was used to determine its purity and the regiochemistry of the products. The methyl benzoate reaction product‚ methyl nitrobenzoate‚ was determined to be meta-substituted

    We performed two procedures in which we reduced methyl acetoacetate. For the first procedure we produced a racemic mixture of Methyl (S)-3-Hydroxyacetate and Methyl (R)-3-Hydroxyacetate. For the second we produced only one of the enantiomer products depending on which enantiomer of Tartaric Acid was used. A reduction is a reaction which generally means adding more carbon-hydrogen bonds to a compound. In a reduction reaction the oxidation number of a carbon atom decreases. The opposite is an oxidation

    ABSTRACT This experiment was conducted to synthesize methyl benzoate form benzoic acid and methanol by using the Fischer esterification method. The Fischer exterification technique is utilized in the academic and industrial settings due to the simplified synthesis and safety parameters of the overall reaction. Both benzoic acid and methanol are relatively cheap to obtain from a commercial source as well as being easy to store with a relatively long shelf life. The Fischer esterification method is
