Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 622-88-8, Name is (4-Bromophenyl)hydrazine hydrochloride, molecular formula is C6H8BrClN2, belongs to phthalazine compound, is a common compound. In a patnet, author is Zhao, Shanshan, once mentioned the new application about 622-88-8, COA of Formula: C6H8BrClN2.
Thermostable PPESK/TiO2 nanocomposite ultrafiltration membrane for high temperature condensed water treatment
Poly (phthalazine ether sulfone ketone) (PPESK)/TiO2 organic-inorganic composite ultrafiltration (OF) membranes with enhanced performance for high temperature condensed water treatment were prepared using a phase-inversion method. The effects of TiO2 concentration on the membrane morphologies, physic-chemical properties, membrane permeability and antifouling performance were investigated and discussed. The SEM result reveals that the penetrated finger-like structure in sublayer is suppressed, and sponge-like structure begins to be developed. The mechanical strength and thermal stability of composite membrane are improved due to the existence of hydrogen bond between TiO2 and polymer. The permeate flux is also enlarged due to the improved hydrophilicity and porosity. Compared with neat PPESK membrane, the composite membranes present improved antifouling properties, showing lower filtration resistances, MEI values and better flux recover property during high temperature condensed water treatment. The optimal addition amount of TiO2 is 2 wt.%. The high temperature condensed water with excess oil and iron can be treated efficiently using PPESK/TiO2 composite membrane. The turbidity of feed solution is almost removed. The oil and iron concentrations in permeate solution are 0.89 mg/L and 26.4 mu g/L which meet the Quality Criterion of Water and Steam for Steam Power Equipment in China. (C) 2012 Elsevier B.V.
