Quaternary ammonium salt organic silicon gemini surfactant and preparation method thereof

The invention relates to a quaternary ammonium salt organic silicon gemini surfactant and a preparation method thereof. The preparation method is prepared by the following steps of mixing polyethylene glycol diglycidyl ether, alpha-hydrogen-omega-hydroxyl-polydimethylsiloxane and acetone, adding tetrabutylammonium bromide and sodium hydroxide solutions, stirring and refluxing at the temperature of 50 to 70 DEG C, so as to obtain epoxy polyether-modified siloxane; adding a hydrochloric acid solution, long-strand alkyl dimethye third amine and a solvent into a reactor, uniformly stirring, dripping the epoxy polyether-modified siloxane, and reacting until the amine value is not changed, so as to obtain a target product. The quaternary ammonium salt organic silicon gemini surfactant has the advantages that the product has excellent surface activity, the surface tension in the water solution is minimum to 28.24mN/m, and the critical micelle concentration is minimum to 1.5*10-6mol/L, and is far lower than the critical micelle concentration of the traditional hydrocarbon single-strand surfactant DTAB (dodecyl trimethyl ammonium bromide); by using the linking of covalent bonds, the hydrolysis resistance property or organic silicon is improved; the advantages of the quaternary ammonium salt organic silicon gemini surfactant and the organic silicon surfactant are simultaneously realized.

Method for simultaneous desulfurization denitrification and mercury removal based on hydroxyl and sulphate radical oxidation

The invention relates to a method for simultaneous desulfurization denitrification and mercury removal based on hydroxyl and sulphate radical oxidation. According to the method, ultraviolet radiation is adopted to decompose peroxide to produce hydroxyl and sulphate radical with strong oxidizing property, which serves as an oxidizing agent, and oxidation is performed in an impact bed, so as remove SO2, NOx and Hg0 in flue gas. The flue gas from an emission source is mixed with peroxide solution and then is sprayed into the impact bed at a high speed through coaxially and oppositely distributed nozzles, and two atomized gas-liquid mixtures are oppositely impacted and mixed in the impact bed. Ultraviolet radiation decomposes the peroxide in the solution to produce hydroxyl and sulphate radical to oxidize and remove the SO2, NOx and Hg0; divalent mercury produced during reaction enters a mercury separation tower, so as to be separated and recycled; sulfuric acid and nitric acid solution enter an absorption tower to produce ammonium sulfate and ammonium nitrate solution; the ammonium sulfate and ammonium nitrate solution finally enter an evaporation crystallization tower to produce solid ammonium sulfate and ammonium nitrate solution. A system can realizes complete removal of the SO2, NOx and Hg0, no secondary pollution exists during removal, and the method has a wide market application prospect.

Synthetic method and application of N, N'-bis-[3-hydroxy-4-(2-benzothiazole)phenyl] carbamide

The invention relates to the field of chemistry, in particular to a synthetic method and application of N, N'-bis-[3-hydroxy-4-(2-benzothiazole)phenyl] carbamide. The molecular structural formula of the N,N'-2-[3-hydroxy-4-(2-benzothiazole)phenyl] carbamide is shown at the right; and the synthetic method of the N, N'-bis-[3-hydroxy-4-(2-benzothiazole)phenyl] carbamide comprises the step that 2-(4-amido-2-hydroxybenzene radical) benzothiazole, 4-AHBA for short, and carbonyl imidazole, CDI for short, are used as raw materials and react in toluene, benzene or xylene solvents to obtain the N, N'-bis-[3-hydroxy-4-(2-benzothiazole)phenyl] carbamide, for short 4-DHBTU. The reaction equation is shown at the right upper part. The invention has available reaction raw materials, mild reaction conditions and high yield; any other catalysts and (or) reaction auxiliary agents do not need to be added in the reaction process, the operation is simple and safe, the phenolic hydroxyl radical of the 4-AHBA does not need to be protected, and the recovery of a byproduct of the imidazole is convenient; and the 4-DHBTU is used as a fluorescent probe and used for the detection of Zn, the concentration lower limit of the Zn is measured and can reach 1*10mol / L, and Fe, Fe, Cd, Co, Mn, Cu, Ni, Ag, Sn, La and Pb all do not interfere the measurement of the concentration of the Zn.
