Ethylene glycol Essays

What Is It? Ethylene glycol is an organic compound, specifically an alcohol that belongs to the –OH functional group; it is composed of carbon, hydrogen, and oxygen with the chemical formula of C2H6O2. It is a colourless, clear liquid with a syrupy consistency and sweet taste; it has no odor however. Ethylene glycol has a melting point of −12.9 °C (8.8 °F; 260.2 K) and boiling point of 197.3 °C (387.1 °F; 470.4 K). Ethylene glycol is soluble in most organic solvents. It was French chemist, Charles-Adolphe

Checkers – Redesigned fast food flavours Fast food or food on the go is one of the fastest growing industries. A conventional fast food restaurant will have a walk up counter and/or drive-thru window to place order and pick up food without long wait. They are popular because they serve filling foods that taste good and cost less. For years such diners dominated the casual restaurants or eat ins. The launch of Checkers was a step above these restaurants. Their double lanes drive in and dine in restaurants

Water potential is often represented by the Greek letter, psi ψ .The higher the rate of collisions of the water molecules with the membrane, the greater the pressure on it. This pressure is called water potential. Water always moves from higher water potential to lower water potential. The standard unit for water potential is kilopascals (kPa), which is also the unit pressure. Pure water is designated a water potential of zero which has the highest water potential under atmospheric pressure at 25°C

by The Food Trust, a regional advocacy group that gets funding from a variety of public and private sources (Hargreaves, 2015). The Trust provides training on how to handle fresh produce, like not storing bananas next to apples, as apples give off ethylene, which rots the bananas. In addition, the Trust gives advice on how to sell produce, as well as training with ordering and bookkeeping (Hargreaves, 2015). In the

Teenagers and Depression Teenagers experience a great deal of life changing events and some studies even suggest that the teenage years may be the most stressful time in people lives. Academics' are the most effective in teenage depression; putting in effort to make exceptional grades, pass exams and having enough credits to graduate. Another cause of teenage depression is sleep deprivation, which consist of unhealthy sleeping habits due to studying late and fitting in a healthy social life. Teenagers

The sociological imagination can be used to explain why people continue to smoke despite being aware of the health risks involved. The Sociological imagination is the shift from viewing social issues and diseases through a personal perspective to considering all the social factors that influence and shape the social issues and diseases within our lives. (Gilbert, Selikow, & Walker, 2010) A social issue that is largely influenced by society is smoking, because studies that will be discussed later

Health Benefits The primary thing that makes most people consider e-smoking, I think, is the potential health benefits that it can have as an alternative to tobacco. The substance that you inhale — e-liquid — typically has four ingredients: propylene glycol, vegetable glycerin, nicotine and food-grade flavors. Cigarette smoke contains substances such as carbon monoxide, tar, arsenic, ammonia, cyanide and acetone among many others. So, it may be possible that e-cigarettes are a safer alternative. In fact

causing lots of problems and hurt to the characters. Shelley’s warning has now caught up to us and Vapes and/or Electronic Cigarettes are the Frankensteins shelly was teaching us about. Vapes have a juice that contains vegetable glycerin, and propylene glycol, two ingredients commonly used in food products and in fogging machines. It also contains a flavor product and nicotine. This is all mixed together and fired from a battery that creates an electric circuit to a coil which in return heats the juice

extract botanicals. This is the ingredient that produces the smoke-like vapor when the electronic cigarette is inhaled. There are approximately twenty percent vegetable glycerin in all e-juices, however sometimes they use seventy percent propylene glycol and thirty percent vegetable glycerin. The Food and Drug Administration has classified glycerin as "generally recognized as safe". The risk of being allergic to Vegetable Glycerin is very small. The only population that is really affected by this

are present in everyday life in a variety of places. Ethylene glycol, commonly found in antifreeze and other household products. Ethylene glycol can be toxic to humans, as well as pets. With antifreeze founds in many households, it is common for pets to find and ingest this toxin. Commonly found in garages where antifreeze is kept, the sweet tasting liquid is often was entices pets to drink it up. Even in the smallest amounts, ethylene glycol has been proven toxic. Dogs often lap it up in the garage

Amorphous density (at 25oC) is 1.33 g/cm3. PET can be produced by 2 different reactions as a product of polymerization. The first reaction is between ethylene glycol with terephthalic acid. The second one is the reaction of ethylene glycol with dimethyl terephthalate in acid catalyst. Figure 2: Molecular Structure of ethylene glycol Ethylene glycol is an organic compound with the formula (CH2OH)2. It is

medium for mixing, ethylene glycol is for formation of gel in this projectIn this project, different stoichiometric

available. Production: Polyethylene terephthalate is made by the condensation of terephthalic acid, or a derivative such as dimethyl terephthalate, with ethylene glycol. Reaction a. Ethylene Glycol: It is made by the catalytic oxidation of ethylene, which is obtained from petroleum craching. Ethylene oxide is produced . Hydration of this yields ethylene glycol

lab admitted that in his initial tests on Randy Thompson's samples he made a mathematical error which led him to say that the levels of ethylene glycol found in Thompson's blood were not significant. Once he re-examined the samples he ran a test on Thompson's urine samples and blood and concluded in the end that there definitely was a high level of ethylene glycol in the victim's body. This clearly shows that the toxicologist's research plays a huge role in a case because if Tilson would have kept

allows one to carry out hydrolysis reactions under atmospheric pressure in a large temperature range up to the boiling point of the polyol. Ethylene glycol has been widely used in the polyol process for the synthesis of metal (pure and alloyed) nanoparticles due to its strong reducing power and relatively high boiling point (~1970C). In this method ethylene glycol (fisher scientific 99.5%) is used as solvent and strong base sodium hydroxide (NaOH) (Qualigens 98%) is used as reducing agent along with

IMPROVING THE HEAT REMOVAL RATE OF AN IC ENGINE USING NANO PARTICLE MIXED COOLANT ABSTRACT: Performance of an engine is greatly dependent on the cooling system of the engine. Addition of nanoparticle to coolant changes the physical and chemical properties of coolant. Hence latent heat and thermal conductivity is improved. Quantity of coolant required of heat removal rate is hence decreased. Improving the thermal efficiency of the engine leads to

Rose Bengal-(bis(aminoethyl)ethylene glycol) (2) from Rose Bengal disodium salt (1) The synthesis was done following procedure from [15]. Rose Bengal Na+ salt (915 mg, 0.90 mmol) was dissolved in DMF (2ml) and DIPEA (0.312 ml, 1.80 mmol), HATU (308 mg, 0.81 mmol) were added. After activation for 15 min, the mixture was added to O-Bis-(aminoethyl)ethylene glycol trityl resin (309 mg, 0.31 mmol) preswollen in DMF for 2 hours. The coupling reaction wrapped in aluminum foil was allowed to proceed overnight

Alcohol is abused daily from newly inexperienced drinkers in their teenage child hoods to older alcoholics that live on with their dreadful lives. People are consuming Alcohol beverages all hours of the day. The notice in alcohol contents is steadily increasing now more than the 1920’s when the 18 amendment was officially a federal law. Alcohol is changing year by year, causing more problems than helpfulness to human society in the twenty first century. The most known commonly known alcohols are

Twenty years after the experiments, the U.S. Department of Energy and the University of California Davis are still cleaning up an animal research facility that tested the effects of radiation on hundreds of beagles. Antifreeze that contains ethylene glycol has a sweet taste that attracts animals but is deadly if consumed in even small quantities; one teaspoon can kill a seven-pound cat. The HSUS recommends

died and Ryan’s mother was committed to kill Ryan because FBI found ethylene glycol in his bother. After her mother spent 6 months in jail, the scientists confirmed that the reason of Ryan death was because of MMA which caused genetic disorder. By knowing this story and studying the concept, it helps me easily to remember the property of this substance and to apply on my lab experiments. Especially when I work with ethylene glycol, it knows it a toxic substance, so I need to handle or carefully perform
