Chemical Characterization
Diethylene glycol monomethyl ether 2-(2-Methoxyethoxy)-ethanol
CAS-No.: 111-77-3
EINECS-No.: 203-906-6
Product Description
Methyl diglycol is a colorless, neutral, weakly hygroscopic and liquid with a mild pleasant odor. It is miscible in any ratio with water and the usual organic solvents e.g. acetone, diethyl ether and methanol. Methyl diglycol is starting material for the production of methyl diglycol acetate. It is also used as a solvent for fats, oils and waxes; constituent of hydraulic fluids; additive in cleaners for soiled surfaces and starting material for syntheses. To prevent dermal exposure methyl diglycol is not suitable for any application in paints and paint strippers. The technical characteristics of methyl diglycol enable it to meet the requirements stipulated for the technical Supply Conditions as drawn up in accordance with MIL-DTL-85470B in addition with an antioxidant (Clariant product name: Methyl diglycol JFA).
Storage Advices
Glycol ethers and their derivatives tend to form peroxides in the presence of air or oxygen. For further informations please refer to the safety data sheet. Storage tanks should be made from norm-steel or stainless steel. Aluminum and other light metals are not suitable due to alcoholate formation with methyl diglycol.
Azeotropic mixtures
Methyl diglycol builds no azeotrope with water and diglycol; nevertheless with several other organic solvents. Some of them are listed

Kimyasal Karakterizasyon
Dietilen glikol monometil eter 2- (2-Metoksietoksi) -etanol
CAS-No .: 111-77-3
EINECS-No .: 203-906-6
Ürün Açklamas
Metil diglikol, renksiz, nötr, zayf higroskopik ve hafif ho kokulu bir svdr. Su ve olaan organik çözücülerle her oranda karabilir, örn. aseton, dietil eter ve metanol. Metil diglikol, metil diglikol asetat üretimi için balangç materyalidir. Ayn zamanda kat yalar, sv yalar ve vakslar için bir çözücü olarak kullanlr; hidrolik svlarn bileeni; kirli yüzeyler için temizleyicilerde katk maddesi ve sentezler için balangç malzemesi. Deri maruziyetini önlemek için metil diglikol, boya ve boya sökücülerdeki herhangi bir uygulama için uygun deildir. Metil diglikolün teknik özellikleri, bir antioksidan (Clariant ürün ad: Metil diglikol JFA) ile birlikte MIL-DTL-85470B’ye göre hazrlanan teknik Tedarik Koullar için öngörülen gereksinimleri karlamasn salar.
Depolama Önerileri
Glikol eterler ve türevleri, hava veya oksijen varlnda peroksitler oluturma eilimindedir. Daha fazla bilgi için lütfen güvenlik veri sayfasna bakn. Depolama tanklar norm çelikten veya paslanmaz çelikten yaplmaldr. Metil diglikol ile alkolat oluumundan dolay alüminyum ve dier hafif metaller uygun deildir.
Azeotropik karmlar
Metil diglikol, su ve diglikol ile azeotrop oluturmaz; yine de birkaç baka organik çözücü ile. Bazlar listelenmitir
