Essays on Benzene

It has come to our knowledge that your company has been using the chemical benzene. We know that benzene is really being used in the manufacturing process. Though it may not be so harmful with limited exposure and small doses, long term exposure can cause a lot of dangerous side effects, illnesses, and diseases. It easily evaporates into the air, dissolves in water and considered as highly flammable (Michon 2016). We would like to inform you the harmful effects of benzene if people are exposed to it for a long time. When we say long term, that means more ...

Creating change in any organization might seem like an insurmountable task given that human beings are usually resistant to change. But is that really true? A lot of employees, as normal workers, in middle and upper management actually embrace change if only they can be convinced of its validity and the manner in which it affects their best interests in a positive manner. No one likes to change anything that seems to working perfectly, right? That's what the employees of the bottled mineral-water company Perrier have been struggling to cope with for a number of years after the organization ...

Introduction

Environmental concerns have created significant interests from various stakeholders with criminologists playing a critical role in responding to environmental harms. Environmental criminology applies to wide range of environments comprising of air, water, and land, and major issues such as overexploitation of natural resources and the emission of high volumes of toxic wastes in air, water, and soil. Multidisciplinary approaches have been adopted to help in curbing such environmental crimes whereby ecological, legal, economic, and social implications of the crimes have been analyzed by various stakeholders. Interventions have also led to extensive methods including monitoring, assessing the damage, enforcing legal ...

Electrophilic Aromatic Substitution to yield 4-Bromoacetanilide

Introduction Halogenation is a common process in organic synthesis. It is used in industrial and research synthesis as halogenated compounds are used for numerous widely used goods, including plastics. The lab aimed to perform monohalogenation of acetanilide. The reaction is specific since it is performed without catalyst. The typical halogenation is realized in presence of Lewis acid. Halogens molecules are electrophilic, and do not actively react. In presence of Lewis acid, the interaction is rather active.2 The lab used catalyst-free halogenation. The acetanilide molecule contains the acylated amine. As a result, the electronic density is shifted towards the amine ...

Abstract

In this experiment, benzene was treated with hydrogen in the presence of Pt/SiO2 as an example that can be applied on industrial operations to show that the most recently modernized methods of neutron total scattering that cover a wide Q-range allow the use of appropriate catalytic chemistry that can be measured on time domain to probe directly on site the hydrogenation of benzene within the catalyst pore. Based on this method, it is possible to study the rates of reaction on length scales that can provide measurements equivalent to the size of an atom or a nanometre. Furthermore, the ...

Assumptions in Molecular Weight Determination and their impact on MW determination

DSC measures the quantity of required heat necessary to melt a sample where the heat of fusion is calculated based on a percentage of crystallinity. Therefore, the methods used to measure crystallinity, weight determination such as DSC must be detailed to retrieve valuable results. However, in most of the molecular weight determination methods, there are certain assumptions undertaken but those assumptions also have a certain impact on results. In DSC profile, three types of distinct probabilities of uncertainty exist. The first is natural uncertainty that may be linked to equipment such as uncertainty of weight measurements of the sample. ...

Introduction

There are environmental chemical processes which require light to react. These processes are called photochemical reactions. Photochemical reaction is commonly initiated due to the absorption of solar energy or light. When molecules absorb energy in the form of light, the atoms are converted in a transient excited state (Larson & Weber, 1994). This transition state or excited has completely different physical and chemical properties with the initial state of the molecule. The excited states also have more tendencies to react since they are considered stronger acids and stronger reductants that the initial state of the molecule. The excited state of ...

According to EPA (2016), environmental management involves the development of systems aimed at reducing environmental impacts of various activities. In the Brundtland commission report (WCED), sustainable development has been described as development aimed at meeting the current needs of the present generation. However, as the current generation focuses on meeting their own needs, their activities should not compromise the capability of future generations to also meet their own needs. Available evidence suggests that the future generation would have challenges meeting their own needs if the current generation fails to adopt sustainable practices. The sustainable development incorporates the triple line: ...
