摘要:在固体亚硝酸钠存在下,某些电子给体与磺胺酸的固-固反应通过在无溶剂条件下以中等产率将磺胺酸(2)进行自催化重氮化而得到偶氮染料.也有一些电子给体与重氮化反应ø硝基苯胺(5),米硝基苯胺(6)和p在催化固体亚硝酸钠的存在下硝基苯胺(7)P-甲苯磺酸(Ptsa)得到偶氮染料在无溶剂条件下,收率很高.这种新方法完全避免了在重氮化和重氮偶联反应中使用酸,碱和有毒和/或昂贵的溶剂.

摘要:The present disclosure includes a method for preparing an aqueous dispersion of γ-Fe 2 O 3 nanoparticles. The method includes grinding an iron (II) hydrated salt, an iron (III) hydrated salt, an inorganic salt, and alkali hydroxide in a grinding or milling machine. The inorganic salt may be a salt matrix that prevents growth and aggregation of the synthesized nanoparticles. The aqueous dispersion of γ-Fe 2 O 3 nanoparticles may optionally be hydrothermally treated to become an aqueous dispersion of α-Fe 2 O 3 nanoparticles. Also disclosed is a method for preparing an mixture of α-Fe 2 O 3 nanoparticles and γ-Fe 2 O 3 nanoparticles, in which at least an iron (III) hydrated salt, an inorganic salt, and alkali hydroxide are ground in a grinding or milling machine. Uses for the nanoparticles include: a magnetic resonance image contrast agent, a color print ink, an artificial tanning pigment, a photocatalyst for degradation of organic dye, a red pigment, an adsorbent for waste water treatment, a catalyst support, and a catalyst.

标题:Green synthesis method of antibacterial super-porous hydrogel, product of antibacterial super-porous hydrogel and application of antibacterial super-porous hydrogel to degradation of various pollutants in wastewater treatment

摘要:Disclosed are a green synthesis method of an antibacterial super-porous hydrogel, a product of the antibacterial super-porous hydrogel and an application of the antibacterial super-porous hydrogel to degradation of various pollutants in wastewater treatment. The super-porous hydrogel based on poly (ionic liquid) is prepared by copolymerization of an imidazole type ionic liquid with double bonds and polyethylene glycol diacrylate (PEGDA) as a cross-linker. In the reaction system, water is a good solvent for the monomer ionic liquid and PEGDA, but a poor solvent for the poly (ionic liquid); when an initial concentration of the ionic liquid is higher than 25%, the phase separation typically proceeds through poly(ionic liquid) formation, interconnected networks with macroporous structure could be obtained by photo-crosslinking.

权利人:UNIV NORTH CAROLINA STATE
摘要:Provided are MOF-fabric composites having a crystalline MOF adhered directly to fibers of the fabric and methods of making MOF-fabric composites. A solution is adsorbed onto a fabric. The solution can include a metal salt, a linker, and a solvent. The solution is adsorbed onto the fabric and the fabric suspended over a heated vapor. The vapor releases onto the fabric, causing the metal salt, the linker, and the solvent to diffuse out of the polymer fibers. The linker links metal from the metal salts to form crystals attached to the fabric, and the vapor aids crystallization.

摘要:The present invention is related to a process for obtaining organic ammonium salts (OAS) and their derivatives, supramolecular surfactants (SS), which simultaneously present the properties of traceability and detergents dispersant of organic scales. Organic ammonium salts (OAS) and their derivatives supramolecular surfactants (SS) have applications as differentiators, markers, or tracers in fuels derived from hydrocarbons; and also to disperse organic scales or inhibit the gums precipitation both in injectors and intake valves of automotive vehicle engines. Organic ammonium salts (OAS) are obtained through an acid-base reaction between a molecule from the azo family and an amine. Once the OAS is obtained, it reacts with an organic compound (OC) so that through non-covalent interactions, a self-assembly process occurs that gives rise to the SS. Said process is based on green chemistry, that is, in the absence of solvents. These OAS and SS are quantified through the analytical techniques of ultraviolet-visible (UV-VIS) and high-performance liquid chromatography (HPLC) through a calibration curve. Additionally, its performance as a gum-dispersing agent in a single-cylinder engine is evaluated.
