Coupling heat curing and surface modification for the fabrication of high permselectivity polyamide nanofiltration membranes

Surface modification is an efficient post-treatment method to optimize the properties of nanofiltration (NF) membranes. Here, we report a facile surface modification strategy coupling with heat curing for grafting monoethanolamine (MEA), a monomer containing both a primary amine and a primary alcohol group, onto a nascent polyamide NF membrane. With grafting 0.5 wt% MEA at 50 degrees C, the pure water permeability of the polyamide NF membranes was improved from 7.9 to 19.5 L m(-2) h(-1) bar(-1) due to their enhanced physicochemical property, such as superior hydrophilicity, rough surface morphology, and enlarged membrane pores. Meanwhile, the rejection of Na2SO4 remained above 97.5%. More importantly, the optimal membrane modified with 0.5 wt% MEA exhibited a high Na2SO4 rejection of 99.1% and a negative NaCl rejection of -20.1% when treating a mixed salt solution containing 2 g/L Na2SO4 and 2 g/L NaCl. Our study provides a novel insight for the fabrication of high permselectivity NF membranes via surface modification.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 100442-33-9, in my other articles.

Application of 100442-33-9, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.100442-33-9, name is 1-(3,3-Diphenyl-N-methylpropylamino)-2-methyl-2-propanol, molecular formula is C20H27NO, molecular weight is 297.4345, as common compound, the synthetic route is as follows.

2,N-Dimethyl-N-(3,3-diphenylpropyl)-l-amino-2-propanol (5g) and methyl acetoactate (7.5g) were dissolved in xylene (50 ml) at 25-30C followed by the addition of zinc dust (1.75g). The reaction mixture was heated at 140-145C for 7 hours. Next,25 xylene was distilled out along with simultaneous addition of xylene in order to maintain the volume of xylene in the reaction mixture. The reaction mixture was cooled at 25- 30C followed by filtration to remove the catalyst. Distillation was carried out to remove xylene under reduced pressure. The resulting residue was degassed for 1 hour to produce title compound as viscous brown oil.

Statistics shows that 100442-33-9 is playing an increasingly important role. we look forward to future research findings about 1-(3,3-Diphenyl-N-methylpropylamino)-2-methyl-2-propanol.
