Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics, 106261-49-8, Name is 4-[(4-Methylpiperazin-1-yl)methyl]benzoic acid dihydrochloride, SMILES is Cl.Cl.CN1CCN(CC1)CC2=CC=C(C(=O)O)C=C2, belongs to piperazines compound. In a document, author is Breite, Daniel, introduce the new discover, Computed Properties of C13H20Cl2N2O2.
Reduction of Biofouling of a Microfiltration Membrane Using Amide Functionalities-Hydrophilization without Changes in Morphology
A major goal of membrane science is the improvement of the membrane performance and the reduction of fouling effects, which occur during most aqueous filtration applications. Increasing the surface hydrophilicity can improve the membrane performance (in case of aqueous media) and decelerates membrane fouling. In this study, a PES microfiltration membrane (14,600 L m(-2)h(-1)bar(-1)) was hydrophilized using a hydrophilic surface coating based on amide functionalities, converting the hydrophobic membrane surface (water contact angle, WCA: similar to 90 degrees) into an extremely hydrophilic one (WCA: similar to 30 degrees). The amide layer was created by first immobilizing piperazine to the membrane surface via electron beam irradiation. Subsequently, a reaction with 1,3,5-benzenetricarbonyl trichloride (TMC) was applied to generate an amide structure. The presented approach resulted in a hydrophilic membrane surface, while maintaining permeance of the membrane without pore blocking. All membranes were investigated regarding their permeance, porosity, average pore size, morphology (SEM), chemical composition (XPS), and wettability. Soxhlet extraction was carried out to demonstrate the stability of the applied coating. The improvement of the modified membranes was demonstrated using dead-end filtration of algae solutions. After three fouling cycles, about 60% of the initial permeance remain for the modified membranes, while only similar to 25% remain for the reference.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 106261-49-8 is helpful to your research. Computed Properties of C13H20Cl2N2O2.
