In this experiment‚ we used methyl benzoate from the last experiment with HNO3 and H2SO4 to synthesize methyl 3-nitrobenzoate. First we added methyl benzoate to 12 mL cooled conc. Sulfuric acid in a flask. In a separate flask‚ we made a solution of 4 mL conc. Sulfuric acid and 4 mL nitric acid and then added dropwise to the solution of methyl benzoate in an ice bath on a stir plate while maintaining the temperature of reaction between 5-15 °C. After the addition was complete we took the flask out

para-hydroxybenzoic acid‚ which is why they are collectively called parabens. However‚ in contrast to its cousins‚ ethylparaben‚ butylparaben‚ and propylparaben‚ methylparaben receives its specific name owing to the fact that its chemical structure contains the methyl alkyl group. Methylparaben is found in several fruits‚ in particular blueberries‚ where it acts as an antimicrobial agent. Methylparaben is an anti-fungal agent often used in a variety of cosmetics and personal-care products. Methylparaben is commonly

4-4 Boiling Point Elevation If you dissolve a substance such as ordinary table salt (NaCl) in water‚ the boiling point of the water will increase relative to the boiling point of the pure water. In this assignment‚ you will dissolve a sample of NaCl in water and then measure the boiling point elevation for the solution. 1. Start Virtual ChemLab and select Boiling Point Elevation from the list of assignments. The lab will open in the Calorimetry laboratory with a calorimeter on the lab bench

4. Paragraphs 1-4 In User Domain the people are often the weakest link in IT security. In Workstation Domain is vulnerable if not kept up to date. In LAN-to-WAN Domain IP addresses are accessible from anywhere in the world‚ and attackers are constantly probing public IP addresses. They look for vulnerabilities and when one is found‚ they pounce. In Remote Access Domain is vulnerable to authentication because when the user provides credentials to prove identity‚ if found the attacker can later

Methyl Red and Voges-Proskauer Test The Methyl Red test shows which bacteria are creating stable acids through mixed acid fermentation of glucose. This helps to identify enteric bacteria by examining how they metabolise glucose. Every enteric bacteria first produces pyruvic acid from metabolism of glucose. A methyl red positive enteric bacteria‚ uses the mixed acid pathway when breaking down pyruvic acid to different acids‚ like lactic‚ acetic‚ and formic acids. The Voges-Proskauer test determines

In this experiment the initial mass of the sodium carbonate used was 2.69g. In each titration‚ 3 drops of methyl orange was added to the sodium carbonate solution. With this information the titration can begin‚ and the results obtained are shown below: Titration readings Titration Rough 1 2 3 4 5 Initial 0.00 4.30 22.00 21.00 15.00 25.90 Final 4.30 22.00 38.60 37.60 32.60 42.20 Titre (cm3) 4.30 17.70 16.60 16.60 17.60 16.30 Therefore‚ the average titre would be calculated as follows;

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

Title: Preparation of Cyclohexene from Cyclohexanol Aim: To prepare an alkene‚ cyclohexene‚ by the dehydration of an alcohol‚ cyclohexanol‚ and better understand the processes that take place during this reaction. Introduction: One of the common ways of preparing an alkene is through the dehydration of an alcohol. In this experiment cyclohexanol is dehydrated to prepare cyclohexene while using sulfuric acid as a catalyst. A bromine test can be later done to ensure that the end product is
