    Ethylene glycol ( CAS # 107-21-1), also known as monoethylene glycol (MEG), 1,2-ethanediol, 2-hydroxyethanol, dihydroxyethanol, glycol, glycol alcohol, and ethylene alcohol , is a toxic, colorless, odorless, sweet, and viscous liquid (NLM, 2012). It is a member of the glycol family, a group of simple organic chemicals characterized by two hydroxyl (-OH) groups at adjacent positions on a hydrocarbon chain (WHO, 2002). This unique chemical arrangement contributes to: high solubility in water, lower

    All animals are susceptible to ethylene glycol toxicity, but it is most common in dogs and cats. Most intoxication is associated with ingestion of antifreeze, which is typically 95% ethylene glycol. Cats are susceptible to ethylene glycol toxicity with a minimum toxic dose of just 1.4 ml/kg. Exposure occurs when cats drink the toxin which has a sweet taste or when anti-freeze is added to water sources or their coats/feet are contaminated with the chemical. Some of the initial clinical signs or symptoms

    Ethylene Glycol also called antifreeze is a sweet tasting, odorless liquid. Due to the sweet taste cats willingly drink the liquid that has leaked on garage floors or driveways. Only a tiny amount can result in severe poisoning in cats. The toxic dose in cats is 1.4 ml/kg (Browne, 2016). For example, a 3kg (6.6lbs) only needs to drink a teaspoon to be lethal. Dogs, poultry, swine and cattle are other species that can be affected by the toxicity. When the cat ingests the ethylene glycol is then absorbed

    purified by distillation or crystallization. This is then allowed to react with the glycol by ester interchange. The reaction generally is a two-step reaction a. First, low MW polyester is made with excess of glycol to ensure that the hydroxyl end groups are formed and then the temperature is raised and pressure is decreased to facilitate condensation of these molecules by ester interchange simultaneously with the loss of glycol. [7] PET resins can be produced in two ways commercially. These two ways are

    I enjoy a nice, cold Coke as much as anyone else does. The sweet carbonation is quite refreshing when its over 100 degrees outside which is pretty much every day. Coke is my favorite soda but the negative aspects of it really outweigh the positive. Is there really any positive reason to be drinking Coke? Other than cooling off there really isn’t any positive aspect of drinking it. Sometimes I wonder why it hasn’t been banned yet. I’m not just talking about banning it in America, I’m talking about

    Abstract During this research paper we will be looking into the definition of flight into known icing as it’s described by the Federal Aviation Administration (FAA) with special emphasis on the word known or forecasted icing as a legal requirement for both pilots and aircraft. We will look at aircraft systems designed for such operations and we will be analyzing the misunderstanding that many pilots have about this issue. One of the biggest misconceptions is that an aircraft equipped with deicing

    level are needed. 9. Based on laboratory results, this patient has co ingested a toxic alcohol i.e. methanol, eythlene glycol, isopropyl alcohol. Other lab tests that could be ordered to confirm diagnosis include measuring blood levels for methanol or ethylene glycol. Urine can also be obtained to see if calcium oxalate crystals are present to confirm diagnosis of ethylene glycol ingestion. I could also request for a blood lactate to rule out lactic acidosis which could be explained by the decrease

    ETHYLENE GLYCOL Description Ethylene glycol is a colorless, odorless, sweet-tasting chemical. It is poisonous if swallowed. Ethylene glycol was once thought innocuous; in 1931 it was suggested as being suitable for use as a vehicle or solvent for injectable pharmaceutical preparations. Numerous cases of poisoning have been reported since then, and it has been shown to be toxic to humans. Ethylene glycol poisoning is a relatively common occurrence worldwide. Human poisoning often occurs in isolated
