Product Description

CAS: 298-07-7, IUPAC name: Bis(2-ethylhexyl) hydrogen phosphate.
Normally it is used to remove impurities, then use DZ272 to extract cobalt and magnesium instead of P507, then get nickel from Laterite-Nickel Ore, the efficiency will be raised too much. This is the reason why we recover to produce this old product again.
