666 results about "Nitryl" patented technology

Nitryl is the nitrogen dioxide (NO₂) moiety when it occurs in a larger compound as a univalent fragment. Examples include nitryl fluoride (NO₂F) and nitryl chloride (NO₂Cl). Like nitrogen dioxide, the nitryl moiety contains a nitrogen atom with two bonds to the two oxygen atoms, and a third bond shared equally between the nitrogen and the two oxygen atoms. The nitrogen-centred radical is then free to form a bond with another univalent fragment (X) to produce an N-X bond, where X can be F, Cl, OH, etc.

Method for synthesizing permanent violet

The invention discloses a method for synthesizing permanent violet. The method comprises the following steps of: 1) alkylating, namely, in a closed reaction kettle, putting carbazole into solution consisting of an inert halogenated aryl hydrocarbon solvent and an alkali metal hydroxide; and performing a reaction with bromoethane in the presence of a quaternary ammonium salt catalyst; 2) nitrifying, namely, treating an obtained N-ethyl carbazole-contianing organic phase by using dilute nitric acid; and after cooling, crystallizing and separating, obtaining a midbody 3-nitryl-N-ethyl carbazole by washing paste; 3) reducing, namely, after dissolving a 3-nitryl-N-ethyl carbazole material in inert halogenated aryl hydrocarbon, performing hydrogenated reduction by using fermium-containing Raney's nickel as a catalyst; and 4) performing a condensation reaction and a ring closing reaction. The method has the advantages that: 1) in the alkylation of the invention, the inert halogenated aryl hydrocarbon is taken as a solvent, so that pollution and cost are reduced and production devices are simplified at the same time; 2) in the method, the temperature for the nitration is improved, so that raw material consumption and the discharge of waste water are reduced; and 3) the process of industrial hydrogenated reduction is perfected, so that the problem of waste water reduction treatment is solved basically, and energy consumption is reduced obviously.

Phosphorescent dye parent materials with tetrahedral structure, and application thereof in electroluminescent device

The invention belongs to the technical field of organic electroluminescence material, in particular to a series of phosphorescent dye parent materials with a tetrahedral structure, and the application of the materials in an electroluminescent device. The phosphorescent dye parent materials can be used for a panel display device, a light-emitting diode (LED) and an electronic imaging device. The phosphorescent dye parent material has excellent electronic and hole transmission properties, can be independently used as a luminous layer and a current carrier transmission layer, and can be used as matrix and doped with other fluorescent or phosphorescent dyes. The compound has stronger fluorescent property in a state of solution or solid, can be used for forming an even film, and has better optical stability and thermal stability. R1, R2, R3 and R4 are respectively connected with phenyl group by a single bond, and are respectively selected from one of hydrogen, alkyl group, alkoxy, nitryl, hydroxyl, cyano-group, benzene cyano-group, amino, sulfydryl, halogen, diphenyl phosphoryl, furan, thiophene, pyrrole, pyridina, diazine, triazine, pyran, quinoline, benzpyrole, carbazole, aniline or phenothiazine, and X is C or Si.

Yellowing-resistant nitro white matt finish and preparation method thereof, use method

The invention relates to anti-yellowing nitryl white matt surface lacquer which is prepared from the following components in weight percentage: 31 to 70 percent of a mixed solvent, 15 to 25 percent of nitrocellulose, 15 to 30 percent of thermosetting acrylic resin, 0.3 to 0.5 percent of a dispersant, 10 to 20 percent of rutile type titanium pigment, 0.1 to 0.3 percent of a leveling agent, 0.2 to 1.5 percent of flatting powder and 1.7 to 5 percent of butyl acetate. The preparation method comprises the following steps: the nitrocellulose is pre-dissolved; the mixed solvent and the nitrocellulose are mixed and are dispersed at intermediate speed till the nitrocellulose is fully dissolved; the thermosetting acrylic resin and the dispersant are evenly stirred at low speed and are added with the rutile type titanium pigment, the mixture is dispersed for 15 to 20 minutes at high speed till the fineness is less than or equal to 20 um; the flatting powder is added to the mixture and the mixture is dispersed for 10 to 15 minutes at high speed till the fineness is less than or equal to 25 um; the leveling agent and the butyl acetate are added to the mixture, and the mixture is dispersed for 10 minutes at intermediate speed until the mixture is even; and after the dissolved nitrocellulose is added to the mixture under the low-speed stirring, the mixture is evenly stirred for 10 to 15 minutes at low speed and is filtered to obtain the anti-yellowing nitryl white matt surface lacquer. The lacquer has good anti-yellowing property; when a lacquer film is placed in an indoor place where no sunlight irradiates, the lacquer film has no obvious yellowing within one year; and the lacquer has high weather resistance and gloss retention.
