INTRODUCTION Worldwide, air pollution is a growing threat to human health and the natural environment. One of the major effects of air pollution is acid rain and it is caused by sulfur dioxide (SO2) and nitrogen oxides (NOx) gases. The combustion of high sulphur content fossil fuels can release harmful toxic gases into the air and therefore pose serious environmental problems. Coal, oil and natural gas are major energy resources available in environment where as fuel combustion processes and…

1.1 Introduction/ what is Acid Rain? Acid rain, or acid precipitation is a term used to describe any form of precipitation with a pH of less than 5.6. In recent years, the effects of acid rain are being experienced on a global scale with widespread environmental effects. Primarily, acid rain is caused by emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) from the combustion of fossil fuels. However, even pure rainwater is slightly acidic (pH of 5.6-6.5) due to the reaction between H2O…

Introduction: Nitrous acid (HNO2) is used as a source of nitrosonium ion (N≡O+). The nitrosonium ion by reacting with an aromatic amine converted into a diazonium salt. As diazonium ion is a weak electrophile, it reacts with electron-rich, aromatic coupling agents to produce an azo dye. The products are mainly ortho and para due to the reaction being an electrophilic aromatic substitution Reaction: p-nitroaniline p-nitro benzenediazonium chloride Para-red…

1-phenylazo-2-naphtol, also known as Sudan-1. The first is the diazotization reaction in which a diazonium salt is formed from the conversion of primary aromatic amines, such as aniline, to compounds with the nitroso functional group using a nitrous acid, such as HNO2. The diazonium salt was then used as an electrophile in a coupling reaction with an aromatic compound, β-naphthol. Recrystallization was conducted and yielded 0.18 g of a red-orange compound. The percent yield was determined to be…

T. Heinze et. al. reported the synthesis of new 6-deoxy-6-pheylethylamino cellulose derivatives with DSamino 0.4-0.6 by nucleophilic displacement of cellulose tosylates (DSTos 0.74 and 1.29) with a racemic mixture of 1-phenylethylamine under homogeneous conditions, in DMF/H2O82, scheme 30. The optical properties of these deoxyamino cellulose derivatives was studied. A regioselective synthesis of 6-amino-6-deoxycellulose, 6-N-sulfonated, and 6-N-carboxymethylated deoxycellulose were…

physical properties of the elements that are interacting. As of the experiment, when the copper wire and copper (II) sulfate were put together, no physical change was observed. Moreover, copper is not an active metal and does not react with diluted acids. This leads to the conclusion that no reaction occurred between them.…

Acid Rain is best described as any form of precipitation with high levels of nitric and sulfuric acid. Acid rain or acid deposition is the result of burning of fossil fuels. About two-thirds of SO2 and one-fourth of NOx are released into the air; it comes from electric power generators. These chemicals react would react with water, oxygen, and other substances to form delicate solution of sulfuric and nitric acid to form acidic pollutants. The source of sulphur dioxide comes from volcanoes,…

ABSTRACT: Terpolymer / kaolinite microcomposites were synthesized by 2:2:1 molar ratio of aniline, anthranilic acid and o-phenylenediamine monomers, respectively using various percentages of kaolinite clay via modified in situ oxidative ter-polymerization. The results were confirmed by FT-IR and UV-Vis absorption spectra of terpolymers / kaolinite composites. The thermal behaviour of the terpolymer and composites was studied. Terpolymers / kaolinite composites were thermally more stable than…
