Typical physical properties


DIETHYLENE GLYCOL Description The characteristics of MEGlobal's diethylene glycol (DEG) products supplement our monoethylene glycol (MEG) portfolio, augmenting our capabilities to include applications that require hygroscopicity, lubricants and low volatility. Products that capitalize on these and other DEG properties include: Drywall joint compound
Thermoplastic polyurethanes
Glass- and cement-grinding aids
Furniture and shoe polishes
Printing ink
Diethylene Glycol is a colorless, low-volatility, low viscosity, hygroscopic liquid. Under normal conditions, diethylene glycol has no detectable odor; however, under high vapor concentrations, a slightly sweet odor may be detected. It is completely miscible with water and many organic liquids. Because of its higher molecular weight, diethylene glycol is considerably less volatile than ethylene glycol and differs sufficiently in that it has specialized uses. The reactivity and solubility of diethylene glycol provide the basis for many applications. Hydroxyls The hydroxyl groups on glycols undergo alcohol chemistry, providing opportunities for production of a wide variety of derivatives. Hydroxyls can be converted to aldehydes, alkyl halides, amines, azides, carboxylic acids, ethers, mercaptans, nitrate esters, nitriles, nitrite esters, organic esters, peroxides, phosphate esters and sulfate esters.

Plasticizer for paper, composition cork, glues, adhesives, bookbinding and coatings
Diethylene Glycol Material Safety Data Sheets MEGlobal encourages and expects customers to read and understand the entire Material Safety Data Sheet (MSDS), as there is important information throughout the document We expect customers to follow the precautions identified in this document unless use conditions would necessitate other appropriate methods or actions. A new MSDS is generated with every shipment of Diethylene Glycol (DEG) for individual grades. The MSDS links below are representative information and are relevant to ALL grades of Diethylene Glycol.

Natural Gas Remove impurities in gas more efficiently and cost effectively - and optimize processing operations - with solutions from Dow Oil & Gas. Our extensive line of industry-tested, proven specialty solvents, along with dedicated monitoring and on-site evaluation of amine system output, can help gas treating operations run more efficiently and economically. Minimize costs, maximize profitability UCARSOL™, SELEXOL™ and SYLTHERM1 product lines help plants stay ahead of tightening regulations by giving customized solutions that absorb more impurities more efficiently. High pressure performance Our SELEXOL™ line of solvents was created to perform at the high pressure requirements of large-scale gasification operations. Its ability to co-absorb impurities at high pressure and release these impurities cleanly during pressure let down results in consistent, easy-to-run syngas operation. Enhanced Oil Recovery: More oil. More efficiently. With oil reserves getting harder to reach and global demand increasing, we're working to develop solutions to help get the most from existing wells. There are innovative technologies to help reach and recover more oil in tertiary operations. We can help achieve more efficient flow through formations with Dow surfactants and polymers for miscible gas and chemical floods. ELEVATE™ line of surfactant products offers innovative chemistries and technologies to help achieve new levels of success in oil recovery operations. We also offer many water treatment solutions to help control contaminants, scale and microbes in injection water and steam processes.
HOLLOW GLASS BUBBLES Need for Low Density Drilling Fluids Increasing necessity to drill deposits which have entered a partially depleted stage. Excessive levels of overbalance pressure can increase fluid invasion. Differential sticking is a costly common problem associated with fluid invasion. Low density fluids, in principle, would permit maximum extraction while minimizing damage to the producing formation from filtrate. A typical methodology consist of using aerated or nitrified muds. An Alternative to Aerated Fluid l An innovative alternative to produce low density drilling fluids consists of incorporating hollow glass spheres (HGS) into conventional drilling fluids.
Additive can be added to virtually any type of existing mud system.
In principle, hollow glass sphere based fluids avoid the problems related to overbalanced drilling.
Technology allows under or near balanced drilling in low pressure formations without the use of air or other gases.
Methodology allows usage of standard mud handling equipment. Hollow Glass Spheres Micrograph of Actual Glass Bubbles, PSD: 10 – 100 microns. Aspect ratio = 1
