Difference between propylene glycol and polyethylene glycol

Polyethylene glycol or polyethylene glycol (PEG) is a polyether with many applications from manufacturing to the medical industry. Polyethylene glycols (PEG) and methoxypolyethylene glycols (MPEG) are some of the most versatile chemical ingredients used either to improve production processes, in applications such as mold release agents, lubricants, anti-static agents and other processing aids or also as chemical intermediates, resulting in foam control products and thickeners. They are also widely used in the medical and chemical industries.

Polyethylene glycol is produced by the interaction of ethylene oxide with water, ethylene glycol or ethylene glycol oligomers. The reaction is catalyzed by acidic or basic catalysts. Ethylene glycol and its oligomers are preferred as starting material instead of water, because they allow the creation of polymers with low polydispersity (narrow molecular weight distribution). Polymer chain length depends on the ratio of the reagents.

What is polyethylene glycol used for?

The solvent molecules exert their action by interacting with and surrounding the solute molecules. This is known as solvation. Polar solutes will be dissolved by polar solvents by establishing electrostatic interactions between the dipoles. Non-polar solvents dissolve non-polar substances by interactions between induced dipoles.

The volatile nature of organic solvents causes them to evaporate rapidly into the air, reaching significant concentrations in confined spaces. The greatest risks to humans are caused by absorption through the skin and inhalation. Direct contact with the skin allows the solvent to pass into the blood, causing immediate and longer-term effects.

To reduce the environmental impact of current organic solvents there are a number of substances that can be used as alternatives, being the so-called alternative solvents or new solvents, belonging to the branch of green chemistry, in which the following principles can be included:

If treated promptly, patients with ethylene glycol poisoning can recover, even from renal failure or coma. However, with delayed or no treatment, ethylene glycol poisoning can be deadly. mercydesmoines.org

Clinical signs present in most cases are: a) tachypnea, as a compensatory mechanism of metabolic acidosis, b) tachycardia and hypotension resulting from dehydration; c) painful abdominal palpation and d) level of consciousness preserved, otherwise other conditions.

Organic solvents

Water vapor drastically decreases the PCI of biogas, facilitates the formation of corrosive acids and causes blockages in the piping system, thus affecting both the operation of the facility and the energy efficiency of the equipment involved in its use as biofuel (engines, turbines, boilers, burners, blowers, etc.).

Therefore, before being used as biofuel, it is appropriate to reduce its moisture content as much as possible. This moisture contained in the biogas is an acid moisture due to the contact with the acid gases present in the biogas (CO2 and H2S), therefore, when it enters the cogeneration system it also produces corrosion.
