Ethylene glycol

Ethylene glycol (antifreeze), chemical formula C2H6O2, is made up of 2 carbon ions (C), 6 hydrogen ions (H), and 2 oxygen ions (O). This ionic compound is used as an engine cooling and de-icing fluid, and when it's mixed with water, ethylene glycol has a freezing point of -45 degrees Celsius, making it perfect for icy winter conditions. When dissolved in water, ethylene glycol disrupts hydrogen bonding, therefore preventing ice from forming. As water freezes, it gets bigger and crystallizes, however

Discussion Three polymers with industrial applications were produced. Ethylene glycol and glycerol both produced polyesters with thermoplastic properties. These plastics are soft and malleable when heated, but solidify once removed from heat. Thermosetting plastics were obtained from a reaction with phthalic anhydride rather than with a carboxylic acid because it is more reactive. The reaction between phthalic anhydride and ethylene glycol produced the linear polyester. Correspondingly, the reaction between

1. Abstract:- Corrosion is a destructive attack of a material by reaction with its environment and a natural potential hazard associated with oil and gas production and transportation facilities. This material degradation results in the loss of mechanical properties like strength, ductility, impact strength and so on. In order to ensure smooth and uninterrupted flow of oil and gas to the end users it is imperative for the field operators, pipeline engineers and designers to be corrosion conscious

using 2D, 3D cell cultures and zebrafish embryos. The polymers to be studie include the well-known cationic transfection agents Poly(ethylenimine) (PEI) and poly(ethylene glycol) (PEG) for their established cytotoxicity as well as the uncharged drug carrier material pHPMA (i.e. poly(N-2-hydroxypropyl) methacrylamide), Poly(ethylene glycol)-b-poly(N-(2-hydroxypropyl)

its product feed over 14 million dogs annual according to Nielsen. However, the brand has come under criticism from bloggers who blame the company of a number of ills, including the use the poisonous ethylene glycol ingredient in its products. Unfortunately, many people are confusing ethylene glycol with the approved propylene

Sharpie markers contain mostly alcohols, however, they also contain ethylene glycol monobutyl ether and permachrome ink. Ethylene glycol monobutyl, also known as 2-butoxyethanol, is an organic compound that is nonvolatile, has a low toxicity, and is used in many domestic and industrial products because of its properties as a surfactant (Wikipedia.com)

The polymer that I choose is polyethylene glycol (PEG). Polyethylene glycol is produced because of the interaction with ethylene oxide with water, ethylene glycol or ethylene glycol oligomers. Some cons of using polyethylene glycol are hypersensitivity, unexpected change in pharmacokinetic behavior, and toxic side products. PEG is also a laxative that can also be used to prepare the bowels before surgery. PEG is also used to slow the clearing of protein from the blood. This makes medicine last longer

Common causes of high anion gap metabolic acidosis (HAGMA) include diabetic ketoacidosis, lactic acidosis, renal failure and toxic ingestions of salicylates, ethylene glycol, methanol and propyl glycol. Pyroglutamic acidosis or 5 oxoprolinuria is an established but often underdiagnosed cause of HAGMA. A sixty-one-year-old woman with a history of type 2 DM on Metformin, Systolic CHF, hypothyroidism, depression, gastric bypass presented to the ED on account of poor oral intake, altered mental status

ABSTRACT Self compacting concrete with suitable chemical admixtures like Super Plasticizer and viscosity modifying agent can be cured, alternatively by addition of an internal curing agent instead of using large quantities of water. Steel fibers on the other hand have been used in cement and concrete composites for more than four decades, most of the steel fibers were introduced in the market prior to 1980. This is in sharp contrast to the continuous progress and development in the cement matrix

Risk is defined by the EPA as “the chance of harmful effects to human health or to ecological systems resulting from exposure to an environmental stressor” (EPA, 2012). The scenario provides us with some basic information about the employee’s tasks. The first is to replenish various engine and mechanical fluids, in order to do this he has to work with substances such as petrochemicals, organic vapors, engine oil, solvents and other decomposition products than can pose a health risk overtime.
