Ürün Açıklaması
Monoetilen glikol dimetil eter, nötr, hafif uçucu renksiz bir sıvıdır. Oksijen atomlarındaki serbest elektron çiftleri nedeniyle, monoetilen glikol dimetil eter yüksek çözme gücüne sahiptir ve su ve tüm yaygın çözücülerle herhangi bir oranda karışabilir. Kimyasal stabilitesinin ve reaktif grupların yokluğunun bir sonucu olarak, monoetilen glikol dimetil eter, birçok organik ve organometalik reaksiyon için (örneğin Suzuki-birleştirme, Simmon-Smith-reaksiyonları, Grignard reaksiyonları) ve polimerizasyonlar için inert bir reaksiyon ortamı olarak kullanılabilir. . Aprotik yeteneklerinden dolayı monoetilen glikol dimetil eter, lityum piller için elektrolitik çözücü olarak da kullanılır (diğer çözücülerle kombinasyon halinde). Daha fazla bilgi için lütfen teknik bültenlerimizi isteyin.

Çözme Gücü
Monoetilen glikol dimetil eter, aşağıdakileri kolaylıkla çözer: alkid reçineleri, bitümler, selüloz nitrat, selüloz aseto bütirat, klorlu kauçuk, kumaron reçineleri, dammar reçineleri, difeniller (klorlanmış), epoksi reçineleri, formaldehit reçineleri, keton reçineleri, fenolik reçineler, formaldehit yağları ®Mowilith, nitroselüloz, bitkisel yağlar, polivinil asetat, klorlu propilen, polistiren boyalar, polivinil klorür (sonradan klorlanmış), sabit yağlar ve vinil klorür. Mumlar ve kresoller yüksek sıcaklıklarda çözünür. Monoetilen glikol dimetil eterde çözünmeyenler şunlardır: gomalak, selüloz nitrat (alkolde çözünür tipler), polivinil karbazol, PTFE, polietilen, polipropilen, poliamid, poliakrilonitril, politereftalik asit glikol ester. Monoetilen glikol dimetil eterde şişen maddeler, doğal ve sentetik kauçuk ve poliakrilatları içerir.

Depolama Önerileri
Monoetilen glikol dimetil eter, karayolu tankerleri, demiryolu tankerleri ve polietilen varillerde tedarik edilmektedir. Glikol eterler ve türevleri, oksijen varlığında peroksitler oluşturabilir. Bu nedenle monoetilen glikol dimetil eter, 100 mg / kg 2,6-Di-tert.-butil-4-metilfenol (BHT) ile depolama stabilize edilir. Ürün higroskopiktir ve su emilimini önlemek için uygun şekilde saklanmalıdır. Bu, ürünü kuru bir nitrojen örtüsü altında saklayarak yapılabilir. Nefes alabilen bir tankta saklanırsa, silika jel gibi kurutucu maddeler kullanılmalıdır. Daha fazla bilgi için lütfen güvenlik veri sayfasına bakın.

Product Description
Monoethylene glycol dimethyl ether is a neutral, slightly volatile colorless liquid. Because of the free electron pairs at the oxygen atoms monoethylene glycol dimethyl ether has high solvating power and is miscible with water and all common solvents in any ratio. As a result of its chemical stability and the absence of reactive groups, monoethylene glycol dimethyl ether can be used as an inert reaction medium for many organic and organometallic reactions (e.g. Suzuki-coupling, Simmon-Smith-reactions, Grignard reactions) and for polymerizations. Because of its aprotic abilities monoethylene glycol dimethyl ether is also used as electrolytic solvent for lithium batteries (in combination with other solvents). For further informations please ask for our technical bulletins. 

Dissolving Power
Monoethylene glycol dimethyl ether readily dissolves the following: alkyd resins, bitumens, cellulose nitrate, cellulose aceto butyrate, chlorinated rubber, coumarone resins, dammar resins, diphenyls (chlorinated), epoxy resins, formaldehyde resins, ketone resins, phenolic resins, mineral oils, ®Mowilith, nitrocellulose, vegetable oils, polyvinyl acetate, chlorinated propylene, polystyrene paints, polyvinyl chloride (post-chlorinated), stand oils, and vinyl chloride. Waxes and cresols are soluble at elevated temperatures. Insoluble in monoethylene glycol dimethyl ether are: shellac, cellulose nitrate (alcohol-soluble types), polyvinyl carbazole, PTFE, polyethylene, polypropylene, polyamide, polyacrylonitrile, polyterephthalic acid glycol ester. Substances that swell in monoethylene glycol dimethyl ether include natural and synthetic rubber and polyacrylates. 

Storage Advices
Monoethylene glycol dimethyl ether is supplied in road tankers, rail tankers and polyethylene drums. Glycol ethers and their derivatives can form peroxides in the presence of oxygen. Therefore monoethylene glycol dimethyl ether is storage stabilized with 100 mg/kg 2,6-Di-tert.-butyl-4- methylphenol (BHT). The product is hygroscopic and must be properly stored in order to prevent water absorption. This can be done by storing the product under a dry nitrogen blanket. If stored in a breathable tank, drying agents such as silica gel should be utilized. For further informations please refer to the safety data sheet.
