    Properties and use of glycol and glycol/water mixtures

    Glycols are organic compounds, which consist of an aliphatic hydrocarbon structure (alkylene radical) and two hydroxyl groups.

    Their scientific name is diols (divalent alcohols), which are derived from ethylene glycol (so-called 1,2-diols, vicinal diols or alkanols) and are represented by the following general chemical formulas.

    C2H2n(OH)2     n = 2, 3, 4 …

    Examples of this are our ethylene glycols and propylene glycols.

    Derivatives of ethylene glycol whose hydroxyl groups do not occupy vicinal positions are also known as glycols. Glycols are frequently used in cooling medium and antifreeze as well as deicers, as the melting point is −10 to −15°C below the melting point of water. In conjunction with water, the melting point is significantly lower still, and can reach as low as −55°C depending on the mixing ratio.

    When using glycol/water mixtures, please note that these mixtures can have a very significant corrosive effect on metals. In this case, the addition of corrosion inhibitors and stabilisers is essential. Our Glysofor concentrates already contain all of the important components to provide optimal corrosion protection for copper, brass, aluminium, solder, steel, iron, grey cast iron, etc.

    We support pure glycols in solvent form and additives for varnishes, paints, and cleaning agents as well as binders for plastics manufacturing and antifreeze production. We supply triethylene glycol, for example, to the oil and gas industry where, due to its hygroscopic properties, it is used as a dehydration agent.

    Ethylene glycol

    (Mono)ethylene glycol (MEG) is colloquially referred to as glycol. MEG is the simplest divalent alcohol with the scientific name ethane-1,2-diol. This makes it the simplest diol. Other diols are diethylene glycol (DEG), triethylene glycol (TEG), or polyethylene glycols. A majority of the glycol produced is used as an antifreeze in aqueous heat transfer fluids and cooling mediums. Due to its freezing point-lowering effect, glycol can also be used as a basic component in deicing fluids for spaceflight. Due to its high boiling point, relative low steam pressure, and good tolerance to water, glycol is also used in conjunction with water as a hydraulic fluid. Glycol is strongly hygroscopic, which makes it suitable as a gas drying agent and sealing fluid. Other applications of glycol are as a solubilising agent and humectant in the field of cosmetics, the production of printing and stamping inks, and as a reactive intermediate product in the production of polyester fibres.

    Diethylene glycol

    Diethylene glycol is colloquially referred to as diglycol. Diethylene glycol is a derivative of ethylene glycol and therefore belongs to the alcohols group. Diethylene glycol is synthesised by the ethoxylation of ethylene glycol with ethylene oxide. In general it occurs as a by-product, during the production of ethylene glycol. The majority of the diethylene glycol produced is used as a raw material for the synthesis of polyester resins. It is also used as a solvent for nitrocellulose, synthetic resins, dyes, oils, and some other organic substances. In addition, diethylene glycol is used as a humectant for tobacco, corks, inks, and adhesives. A mixture of diethylene glycol and water can be used as antifreeze. However ethylene glycol, which is better suited to this purpose, is generally used. In a diethylene glycol/water mixture the boiling point is also increased, indeed to a greater extent than with a water/glycol system. For this reason, diethylene glycol is also used as an additive in hydraulic and brake fluids.

    Triethylene glycol

    Triethylene glycol is colloquially referred to as triglycol. Triethylene glycol is produced by the ethoxylation of diethylene glycol, and occurs as a by-product of ethylene glycol production. Due to its high boiling point, triethylene glycol is used for applications which occur at high temperature (> 200°C). It is an important intermediate product in the production of polyester resins. Due to its odour-neutralising properties, triglycol is used in room air fresheners (air sanitisers). Triglycol also has a drying effect on the ambient air and a dehydrating effect on micro-organisms. Triglycol is used to disinfect the ambient air in areas which high hygiene requirements. Triethylene glycol is also used in braking systems and hydraulic systems to increase the boiling point of the fluid. It is also used to dehumidify natural gas from offshore sources.

    Propylene glycol

    1,2-Propanediol (1,2-Propylene glycol) is a clear, colourless, practically odourless, and strongly hygroscopic liquid. Propylene glycol belongs to the group of polyvalent alkanols. It is miscible with water in any ratio, though not with fatty oils. On an industrial scale, propylene glycol is produced from the hydrolysis of propylene oxide. This uses a high-temperature process without catalysis at 200–220°C. Propylene glycol is contained in hygiene products such as skin creams, toothpaste, and deodorants as a humectant and plasticiser. Propylene glycol can significantly improve the solubility of various substances and ensure a more stable dispersion of pharmaceutical ingredients in ointments. In addition, it can often contribute to significantly improving absorption of various active ingredients. Propylene glycol is used in the food industry as a carrier material or carrier solvent for dyes, antioxidants, emulsifiers, and enzymes. 1,2-Propanediol (1,2-Propylene glycol) is a clear, colourless, practically odourless, and strongly hygroscopic liquid.

Due to its harmless nature, it is contained in heat and cold transfer fluids used in food processing (Glysofor L), antifreezes, cooling brines, solar fluids, etc. Propylene glycol is used as an additive in the feeding of dairy cattle, and is approved in the EU as a food additive (E 1520).
