    Microwave (MW) assisted Esterification of Benzoic Acid (BA) offers the advantage of transformation of energy and heating throughout the volume efficiently in a shorter period and eliminates the use of excess solvent, during the course of reaction. The present study aims to assess the conversion and selectivity for the production of methyl benzoate compounds by esterification of benzoic acid using microwave irradiation. Effects of operating parameters such as reaction time, feed composition,…

    • 2 Pages

    The definition of an accelerant is a substance that accelerates the speed of fire or makes a fire more intense (Accelerant | Define Accelerant at Dictionary.com, n.d.). When forensic laboratories have debris that was collected from a crime scene they can use either the Headspace or the Vapor Concentration techniques to determine if there was an accelerant used. Both techniques use Gas Chromatography, which is separating mixtures based on their distribution between a stationary liquid phase and…

    The purpose of this lab is to observe the different colors produced by different compounds. My hypothesis is that each compound will produce a different color. For the procedure, we first took a wooden splint and placed it in distilled water. Then, we lit matches we received from Mr. Maloney, and turned on the gas which turned on the bunsen burner. We then took one compound from the front table. We took the wooden splint in the water, and scooped up a tiny bit of the substance and placed the…

    Do you ever wonder how glass art is made? It is called glassblowing where artists known as glassblower/gaffers basically blowing air into a 6 ft long pipe that has heated molten glass at the end of it which causes the glass to become larger and shapeable. During this process they will continue to heat the glass in a furnace while in between applying steady rotation by rolling it on a table to to form a shape. Sometimes they may even add some color by rolling the hot glass different colorful…

    • 4 Pages

    2.3.1 MAJOR PROCESSES 2.3.1.1 THERMAL PROCESSES (DISTILLATION) Around half of the world’s desalted water is produced with heat to distill freshwater from seawater. The process of distillation mimics the natural water cycle in that saline water is heated, producing water vapor that condensed to form freshwater. In an industrial plant or laboratory, water is heated to reach the boiling point to produce the maximum water vapor amount. To make it economically in a desalination plant, the…

    The purpose of this lab was to prepare tetraphenylcyclopentadienone most commonly known as tetracyclone. This involved a 3-step synthesis over the course of 3 weeks. The first step was the preparation of benzoin, which was completed through self-condensation of benzaldehyde with thiamine used as the base catalyst of the reaction. The next step was the preparation of benzil from the oxidation reaction of benzoin with nitric acid. In the oxidation reaction, the alcohol functional group of benzoin…
