Toluene

Discussion of Results During the first week the goal was to determine the unknown compound. In order to determine the unknown compound, many tests were performed testing the solubility, pH level, conductivity, cations present (flame test), and the anions present in the compound. The anion test had positive results for the sulfate test due to the formation of a white precipitate, indicating the presence of a sulfate ion. For the sulfate test the unknown solution, potassium sulfate, and combining…

more than 90 percent of shale gas, leak during fracking” (Fracking Is Harmful). Methane itself is not dangerous, but mixed with other substances it can become explosive and harmful. Additionally, volatile organic compounds, including benzene and toluene, are released during fracking (Fracking Is Harmful). These compounds can mix with nitrogen oxide emissions from diesel-fueled vehicles and equipment to form ground-level ozone. “These emissions contribute to the enhanced greenhouse effect and…

How to Grow Nails Faster Nails are layers of a tough protective protein called keratin, and different factors such as your age and health can affect nail growth. Children’s nails grow much faster than adults until they reach puberty, and women who are pregnant also experience a faster nail growl due to an increase in hormones that boost metabolism and increases circulation. However, illness and certain medications can slow down nail growth, and if you want to know how to grow nails faster, you…

Workers in the factories were exposed to toluene which is known to cause damage to the liver, kidneys and central nervous system. In an inspection report that was prepared in January for the company's internal use only, Ernst & Young wrote that workers at the factory near Ho Chi Minh City were exposed…

Stereochemistry conformation is how molecules are orientated in space. There are two basic types of isomers: constitutional or stereoisomers. Constitutional isomers gave the same molecular formula but different connectivity, while stereoisomers have the same connectivity but a different orientation in space. Stereoisomer has two subunits called enantiomers and diastereomers. Enantiomers are molecules that are mirror images, while diastereomers are not mirror images. Stereochemistry focus…

find the unknown compound, to discover the compounds chemical and physical properties and create two synthesis of the compound and compare the two compounds. We found out our compound was ionic because the compound dissolved in water, but not in toluene or acetone by using a solubility test, results on Table 1 of the group lab report. On page 59 of the Cooperative Chemistry Laboratory Manual is a chart on suggested liquids and the inference if the compound is soluble [1]. When then checked the…

The average person today will fill up their vehicles with different grades of petrol, because that is what the common vehicle takes. They normally don’t consider a substitute for the petrol that they fill up their cars with. Although petrol is the most common, it isn’t the only source of power for a car; electricity and diesel can be used instead of the general petrol that powers most automobiles. Although they differ from each other, electricity and diesel are replacements to the average petrol…

We have conducted a case study about air pollution. Air pollution is one of the biggest threat to earth and our existence because air pollution effects the ozone layer in a bad way where it shrinks the thickness of the ozone layer. If the ozone layer disappear, all of the sun rays including healthy and harmful will have contact our skin and body, And will eventually kill us. Air pollution is a combination of gases that surround us in the air. Also we can call it a mixture of chemicals and gases…

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,…
