What is the pH of ethylene glycol?
5.5 to 8.0
According to various manufacturers of uninhibited ethylene glycol, they state this chemical has a pH of 5.5 to 8.0. Most uninhibited ethylene glycol manufacturers do not specify a pH for this chemical; they state not applicable or not available (NA) on the product data sheet or material safety data sheet (MSDS).
Is ethylene glycol acidic or basic?
Ethylene glycol is a diol, an alcohol with a molecular structure that contains two hydroxyl (OH) groups, and terephthalic acid is a dicarboxylic aromatic acid, an acid with a molecular structure that contains a large, six-sided carbon (or aromatic) ring and two carboxyl (CO2H) groups.
What is the pH of propylene glycol?
9.3 to 10.5
Protein/propylene glycol alginate gels can be formed using 6% protein in a suitable 0.1 M buffer solution in the pH range 9.3 to 10.5.
What is mono propylene glycol used for?
Monopropylene glycol USP grade is used in food, beverage and animal feed, in pharmaceuticals as an excipient (inactive ingredient or carrier in a pharmaceutical product), in cosmetics and personal care products. The application of MPG USP for direct injections into the blood system is not allowed.
How do you find the pH of glycol?
Testing Your Glycol pH Level. Using narrow range pH paper is an easy and reliable way to read your pH level. A pH tester can also measure alkalinity or acidity of the fluid. Any fluid with a pH below 7.0 should be replaced.
How do you make mono ethylene glycol?
Mono Ethylene glycol is produced from ethylene, via the intermediate ethylene oxide. Ethylene oxide reacts with water to produce ethylene glycol according to the chemical equation. The major byproducts are the diethylene glycol, triethylene glycol, and poly glycol.

Is ethylene glycol viscous?
Ethylene glycol (CH₂OH₂), also known as 1,2-ethanediol, is an alcohol-based organic compound often used as an anti-freezing agent in HVAC equipment and vehicle systems, among others. Its an odorless, colorless, viscous liquid, known to have a sweet taste.
What glycol is used in boilers?
Installers may use either propylene glycol (non-toxic food-grade antifreeze, recommended where a tankless coil is used on a heating boiler and in some other cases), or ethylene glycol (automotive type and highly toxic antifreeze).
How to calibrate pH in monoethylene glycol (MEG) + water solvents?
A convenient calibration method for pH measurements in monoethylene glycol (MEG) + water solvents is described. The calibration has to be performed once for each electrode type. pH measurements were performed in CO2 (g, 1 bar)-saturated solutions of 60 and 90 wt % MEG at 4−80 °C with varying NaHCO3 and KHCO3 contents.
What is mono ethylene glycol fibre?
Mono Ethylene Glycol – Fibre. Mono Ethylene Glycol (also known as MEG) is a clear, colourless, virtually odourless, and slightly viscous liquid. It is miscible with water, alcohols, and many organic compounds, and has the formula C2H6O2.
What is the density of Mono Ethylene glycol?
Density: 1.115 at 68 °F How is it produced? Mono ethylene glycol is produced industrially using ethylene oxide via hydrolysis. Ethylene oxide is obtained through oxidation and is then reacted with water to give mono ethylene glycol with di and tri ethylene glycols as co-products:
How is mono ethylene glycol stored and distributed?
Storage and distribution Mono Ethylene Glycol can be stored in stainless steel, aluminium, or lined drums, tank cars, or tank trucks. It has a specific gravity of 1.115 and a flash point of 110 °C (closed cup). It is not regulated for transport on road, rail, air, or sea but it is classified as harmful, and is harmful if swallowed.
