  • Importance Of Inhibition Efficiency Of Polymers

    weight. The modification of these properties pave the way for future research in inhibitor technology. Introduction The inherent protection of metals and their alloys used in industry are of the upmost importance when it comes to longevity and reliability of structures. Many chemical compounds have been developed over the years that can inhibit the corrosion rate of metal alloys but cost effectiveness, toxicity, processibility and other factors limit the applications1. The need for new, eco-friendly and cost effective corrosion inhibitors have led to research in the field of polymer chemistry. Discussion The performance of a polymeric corrosion inhibitor is a function of its size and number of functional anchoring groups1. The anchoring groups allow the polymer to adsorb to the metal surface and assist in corrosion mitigation. Other main factors that influence corrosion protection are molecular size, weight, pH, and composition. It has been observed that adsorption characteristics of a polymer strongly depend on…

  • Synthesis Of Benzalknoium Salts

    Benzalknoium salts are acknowledged as benzalknoium chloride, also known as BZK, BKC, BAC, alkyldimethylbenzylammonium chloride and ADBAC. These salts are known to have several names and are also considered as cationic surfactants. Surfactants are compounds that subordinate the surface tension among two liquids or among a liquid and a solid. Surfactants have the availability to act as detergents, wetting agents, emulsifiers, foaming agents, and dispersants. Benzalknoium salts are used in…

  • Principle Of Green Chemistry

    Green chemistry principles were applied to multi-step synthesis reactions; these reactions included the bromination of trans-diphenylethylene, bromination of ethyl trans-cinnamate, and debromination of 1, 2-dibromo-1, 2-diphenylethane. These reactions featured a reflux set-up, which allowed the reactions to occur at higher temperatures and aided in the prevention of the evaporation of the solvent and the loss of product thereby increasing the efficiency of the reactions. Furthermore, the…

  • Liquid Compounding Process Once the components are brought from the Pre-weigh area for batching, the compounder assigned the batch must verify the chemicals and quantities brought from the Pre-weigh department and the weigh tickets must be affixed to the back of the Work Order (do not throw away). If there are any missing tickets stop the process and notify your supervisor for prompt follow-up, you may resume once the ticket and chemical is verified (this is an urgent matter and must be addressed…

  • Chromium: The Most Toxic Chemical Compounds In Industry

    Chromium (Cr) is one of the most toxic chemical compounds due to the common use of chromium compounds in industry in addition to its natural sources (Costa et al., 2003). Exposure to chromium occurs via contaminants found in drinking water and food, through air containing particulates or mists of hexavalent chromium Cr (VI) compounds, or through skin contact with soil at hazardous waste sites (National Institute for Occupational Safety and Health, 2013). Cr (VI) may be found in drinking water…

  • Dangers Of Cannabis

    least 50 percent of the government’s involvement in cannabis should be dedicated to help the public understand the important implications and associations of its use, to fund clinical studies for public health and safety, to research potential risks of mental illness, and regulate publications about the relationship between medical and recreational cannabis. Cannabis may be defined as a psychoactive drug, a chemical substance that changes brain…

  • The Love Canal: A Case Study

    Between 1942 and 1953 there was active dumping of chemicals waste into the canal. Document submitted by Hooker to New York interagency task force of hazardous waste, showed that an estimate of about 21,800 tons of chemicals waste from the manufacturing process of the company was dumped in the canal. “These waste were mainly organic pesticide residues, waste solvents, fly ash and process sludge” (Philip, et al. p 313-314). About 6,900 tons of lindane (hexachlorocyclohexanes), 2000 tons of…

  • Chemical Changes Lab Report

    Chemical changes are everywhere from everyday things such as baking to scientific things such as changing one gas into another. Physical changes are changes that can be observed with senses and change a certain property or properties to a substance but it still remains chemically the same. This can include changes in the state of matter, size and shape. Chemical changes are when the substance is changed chemically with its properties changing with it. The substance with change from one substance…
