Benzene

Abstract A Friedal-Craft reaction was performed to synthesize 1,4-di-t-butyl-2,5-dimethoxy-benzene from p-dimethoxybenzene and t-butyl alcohol. The product of the reaction was filtered using a Hirsch funnel, before recrystallizing and filtering a second time. The recorded mass of the product was .08g and the melting point was 47-52.7 °C. Introduction1 This experiment was designed to practice working with electrophilic aromatic substitution reactions. Specifically, a Friedel-Craft reaction was…

Benzene can be found in certain types of detergents, pesticides, drugs, lubricants, rubbers, and dyes. Once inhaled benzene is rapidly absorbed and widely distributed. Benzene is highly lipophilic and readily crosses the blood brain barrier allowing it to accumulate into the brain. Users experience a feeling of euphoria, headache, and dizziness. Some of the adverse effects of benzene use include serious damage to the bone marrow, toxicity to…

In the years 1940-1950, The Hooker Chemicals and Plastics Corporation used a canal in Niagara Falls, New York, as a dumping ground. The company disposed of toxic chemicals; including polychlorinated biphenyls, dioxin and pesticides. This land was then covered with fill and sold to a developer. A housing development was built on the chemical dump in the 1970s. Residents of the area began to experience various health issues. The government did not begin investigating and relocating families until…

Elias Abejo Acute Myelogenous Leukemia Symptoms: Acute lymphoblastic leukemia is a fast-growing type of leukemia that rapidly creates not fully developed immature blood cells. There are three symptoms of acute myelogenous leukemia that require a medical diagnosis or determines that you have acute myelogenous leukemia. The first symptom that will occur in leukemia is fatigue, or extreme tiredness and lack of energy you will feel all the time. You will also have infections that will occur more…

crises through an evaluation and analysis of the eight step model’s practical application in five real life crisis case studies (Argenti, 2013). The Johnson & Johnson’s Tylenol recall, British Petroleum’s (BP) Deepwater Horizon disaster, Perrier’s benzene contamination crisis, Cadury’s worm infestation, McDonald’s ingredient scandal, and Pepsi-Cola’s syringe hoax will all provide insight into the actual application and theoretical application of the eight step model (Argenti, 2013; Padgett et…

Temazepam, commonly known as Restoril, is a sleeping pill that is prescribed to patients. This drug is classified under a type of drugs called benozaphines, which are, “a large group of drugs with sedative and anxiety-reducing properties, which have been found valuable for a large number of uses” (UXL Encyclopedia of Drugs and Addictive Substances). This class of drugs is used to reduce anxiety and help with insomnia. Since temazepam is classified as a benzodiazepine, I was curious as to what…

The highest bioremoval occurred for toluene/benzene, followed by ethylbenzene and m,p-xylene, and the lowest for o-xylene. For toluene, the lowest bioremoval (76.7%) occurred at run/treatment 13, while the highest bioremoval (98.3%) at run 14 (Table 2). The lowest and highest bioremoval of other hydrocarbons also occurred at runs 13 and 14, respectively. The originally toluene-adapted and toluene-removing bacterium could also remove benzene very well, but not xylenes, even after almost several…

History Morphine was first isolated in its crystal form by pharmacist Friedrich Sertürner in 1817. Because of the pain relief effects of the opium poppy, many chemists were attempting in the decade beforehand to extract what was later to be called morphine. With the extraction of morphine also was a milestone as it was the first alkaloid to be isolated. Since its discovery its use has become widespread both as a painkiller, for its recreational effects, and was once thought to be a cure for…

Montgomery County’s environment was classified amid the filthiest twenty percent, for carcinogen emissions, of all United States counties in 2002. Before that, in 1999, it was categorized among the worst thirty percent in unpredictable organic compound outputs. Also, three percent of homes are vulnerable to a high risk of lead exposure. Fortunately, there are is no record of any waste sites on the EPA’s official list. Therefore, the area most seriously affected by pollution in this particular…

Even though it is said that the current process is legal, I feel like OSHA has not thoroughly gone through the entire process in the company. As per the federal standards, benzene level should be 10 times per million. But the current level is 1000 times per million and this is 10000% higher than the normal level. This will definitely come in to play in the foreseeable future so the company will get punished if they are not…
