Application
EDM can be mainly used as the solvent for nitrocellulose,synthetic resin,painting and printing ink.It can be used as
paint deleting solvent and diluent because of its excellent solubility.And it also can be used as organic synthetic inertia
solvent due to its chemical stability.Besides above usage,DEDM can be used as solvent of water-soluble painting and
leveling agent of leather or fiber mix flating agent in photo or printing.TRIEDM can be used in the organic reaction as
high-boiling point solvent.And it also can be used as desulphurizate agent or decarbon agent for synthetic ammonia or
natural gas.TETREDM can be used as excellent solvent of alkaline metal hydride and it is used in alkyl combination or
recycle chemical reaction.And this chemical compound has Louise alkalinity,it can electively absorb acid gas to purify
the synthetic gas,natural gas and acetylene.(NOTE:this product can`t be exposed outside for a long time,otherwise it can
produce peroxide)
Package:
180KGS/Iron Drum for EDM. 200KGS /Iron Drum for others.
Storage and Transportation:
Store in cool, dry well-ventilated location, for EDM,DEDM transport as hazard chemicals, while the others
transport as common chemicals.

应 用:
乙二醇二甲醚主要用作硝化纤维素、合成树脂、油漆、油墨等的溶剂,其溶解力较强,可作脱漆
剂溶 剂,稀释剂,由于其化学稳定性好,也可作有机合成的惰性溶剂。二乙二醇二甲醚除上述应用外,尚可
作水性 漆的溶剂,皮革及纤维的匀染剂,照相印刷的调平剂。可作为有机合成中使用的非质子极性溶
剂,阴离子聚 合、配位离子聚合的溶剂。三乙二醇二甲醚可作高沸点溶剂用于有机合成反应中,也可用于合
成氨或天然气的 脱硫、脱碳剂。四乙二醇二甲醚可作为碱金氢化物的优良溶剂。用于烷基化缩合和还原
等多种化学反应工艺 中。由于该化合物具有路易斯碱性,所以它能选择吸收酸性气体,用于合成气、天然
气、乙炔等气体的纯化。
(注意:本品不宜长期暴露于空气中,不然会形成过氧化物。)
