application:
edm can be mainly used as the solvent for nitrocellulose, synthetic resin, paint and printing ink. it can be used as paint deleting solvent and diluent because of its excellent solubility. it can also be used as organic synthetic inertia solvent due to its chemical stability.
besides the usage mentioned above, dedm can be used as solvent of water-soluble painting, leveling agent of leather and fiber, leveling agent in photo or printing, and aprotic polar solvent used in organic synthesis.
triedm can be used in the reaction of organic synthesis as high-boiling point solvent. it can also be used as de-sulphurizate agent or de-carbon agent for synthetic ammonia or natural gas.
tetredm can be used as excellent solvent of alkaline metal hydride and used in alkyl combination or recycle chemical reaction. with louise alkalinity, it can selectively 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.)
