GLYCOL ETHERS - Oxiteno

GLYCOL ETHERSGlycol EthersDESCRIPTIONGLYCOL ETHERS result from the reaction of alcohols or phenol with ethylene oxide. Thereactions to obtain these compounds and their molecular structures are shown in the figurebelow, starting from methanol and ethanol. The reactions with butanol and phenol are similar.Oxiteno produces the following types of glycol ethers: methyl glycol (MEGME), methyl diglycol(DEGME), ethyl glycol (MEGEE), ethyl diglycol (DEGEE), ethyl triglycol (TEGEE), butyl glycol(MEGBE), butyl diglycol (DEGBE), butyl triglycol (TEGBE) and ULTRASOLVE ® P 240 A (phenylglycol or MEGFE).The GLYCOL ETHER line is made up of the following products:Product Other denominations CAS 1 numberMETHYL GLYCOLMETHYL DIGLYCOLETHYL GLYCOLETHYL DIGLYCOLETHYL TRIGLYCOLBUTYL GLYCOLBUTYL DIGLYCOLBUTYL TRIGLYCOLMonoethylene glycol methyl ether2-methoxyethanolMEGMEDiethylene glycol methyl etherDEGMEMonoethylene glycol ethyl ether2-ethoxyethanolMEGEEDiethylene glycol ethyl etherDEGEETtriethylene glycol ethyl etherTEGEEMonoethylene glycol butyl ether2-butoxyethanolMEGBEDiethylene glycol butyl etherDEGBETriethylene glycol butyl etherTEGBE109-86-4111-77-3110-80-5111-90-0112-50-5111-76-2112-34-5143-22-6ULTRASOLVE P 240 A Phenyl glycol, Monoethylene glycol phenyl ether, 2-phenoxyethanol, MEGFE 122-99-61.

GLYCOL ETHERSGlycol EthersAPPLICATIONSLeathersETHYL DIGLYCOL, BUTYL GLYCOL, BUTYL DIGLYCOL and BUTYL TRIGLYCOL are used aspenetrating agents in water-based formulas since they reduce the surface tension of water,increasing penetration of paints and lacquers, and improving resistance and leveling of thefilm.INFORMATIVE PROPERTIES (*)ProductAppearance@ 25°CPt-CoColorDensity20/20°CWater(%wt.)Acidity as AceticAcid (ppm)METHYL GLYCOL Clear liquid 10 max. 0.964 - 0.969 0.1 max. 100 max. 124.5METHYL DIGLYCOL Clear liquid 10 max. 1.021 - 1.025 0.1 max. 100 max. 194.2ETHYL GLYCOL Clear liquid 10 max. 0.930 - 0.933 0.1 max. 50 max. 135.1ETHYL DIGLYCOL Clear liquid 10 max. 0.989 - 0.993 0.1 max. 100 max. 202.7ETHYL TRIGLYCOL Clear liquid 100 max. 1.020 - 1.060 0.1 max. 100 max. 245.0BUTYL GLYCOL Clear liquid 10 max. 0.901 - 0.904 0.1 max. 100 max. 171.2BUTYL DIGLYCOL Clear liquid 15 max. 0.954 - 0.958 0.1 max. 100 max. 230.6BUTYL TRIGLYCOL Clear liquid 100 max. 0.990 - 0.997 0.1 max. 100 max. 270.0ULTRASOLVE P 240 A Clear liquid 500 max. 1.09 - 1.13 0.3 max. 500 max. 245.0Boiling Pt.(°C)@ 760mm HgNOTE: (*) The properties described above are informative only and may be altered without prior notice. Please consult the productspecification for current details.HANDLING AND STORAGESince these GLYCOL ETHERS have low vapor pressure, the risks of intoxication from inhalingtheir vapors are small. However, one should avoid prolonged or frequent exposures to theirvapors.During handling, the use of gloves, PVC coat and safety goggles are recommended. Forpotential prolonged exposure, it is advisable to use masks suitable for organic vapors. In caseof accidental contact, act as follows, seeking urgent medical care:• Eyes: wash immediately with abundant water for at least 15 minutes• Skin: remove the contaminated clothing and wash affected parts with abundant water• Ingestion: seek urgent medical care, keeping the head lower than the torso to preventinhaling the product through the lungsContaminated clothes and shoes must be removed and washed before reuse.GLYCOL ETHERS are classified as flammable or combustible substances, depending on theether type and according to its flash point. It is therefore necessary to protect them fromsources of ignition, such as open flames, hot surfaces, electric discharges, etc. Theextinguishing agents are water, dry chemical powder, carbon dioxide and foam.Because GLYCOL ETHERS are hygroscopic, we recommend storing under an inert atmosphere,preferably nitrogen, to minimize water absorption.2

GLYCOL ETHERSGlycol EthersGLYCOL ETHERS should not come in prolonged contact with air due to the possibility offorming peroxides.To store GLYCOL ETHERS, we recommend using AISI 304 or 316 stainless steel tanks.Aluminum and its alloys should be avoided. Polymeric coatings are not recommended due tothe excellent solvency power of GLYCOL ETHERS.® Oxiteno’s Registered Trademark.DISCLAIMERThis bulletin contains information given in good faith, based on Oxiteno’s current knowledgeon the subject, and is purely indicative.
