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.)
200kg/drum; 1000kg/IBC
Storage should be at cool, dry and ventilate.
