Description
Technical field
The invention belongs to the synthesis technical field of Cu-lyt., be specifically related to the green synthesis method of a kind of Cu-lyt..
Background technology
Cu-lyt. is a kind of butter, and for tetrahedral crystal shape or white cubic crystal, appearance color is white or pale powder, sometimes with loose spot shape.Cu-lyt. is slightly soluble in water, poisonous, easy photodissociation, deliquescence, is placed in air the copper chloride hydroxide (Cu being easily oxidized to green2(OH)3Cl), rapidly hydrolysis generates Cu-lyt. hydrate and white in the hot water.The more prominent position of occupation ratio in chlorine derivative product, Cu-lyt. is commonly used for catalyst in organic synthesis industry and rubber industry, such as prepare vinyl acetate with ethylene for raw material, produce a chlorobutadiene, acrylonitrile, second dialkylene acetylene etc., it is possible to prepare diphenyl ether polymerization catalyst with diamidogen；Cu-lyt. can be used as desulfurizing agent, release agent and decolorising agent in petro chemical industry；Oil and fat chemical is used as catalyst, reducing agent and flocculating agent, especially the most famous with catalyst；Except producing aniline dyes in the production of dyestuff, phthalocyanine blue, phthalocyanine green, active emerald green pigment rise outside mantoquita mating reaction, are also serving as condensing agent, catalyst and reducing agent；In silicone industry, highly active Cu-lyt. is the most important purposes of Cu-lyt. as the catalyst that methyl chloride silane mixture monomer synthesizes.High activity Cu-lyt. is the granule crystalline powder without coherent condition, its short texture, but specific surface area is big, there is small-size effect, surface and interfacial effect, quantum size effect etc., outward appearance and the physical arrangement of such Cu-lyt. are the most more complicated, because its activity is high, therefore the nanoscale Cu-lyt. synthesized by certain technique is widely used on Catalytic processes.Additionally have been widely used in metallurgical industry, electroplating industry, medical industry and agriculture chemicals fungicide industry.
The method of traditional mode of production Cu-lyt. mainly has: copper wire air oxidation process, and this method response speed is slow, material and energy expenditure height and copper wire price height and limited source；Copper sulfate method, production cost is high and reaction produces a large amount of acid mist pollution environment, and tiny being difficult to of prepared product granularity is filtered, and product easily aoxidizes；Copper scrap chlorine direct oxidation method, this method uses industrial chlorine direct oxidation, and therefore equipment anticorrosion is poor with production environmental safety；Copper scrap hydrochloric acid method, this method raw material only limits copper scrap mud, otherwise should need to add copper oxide rich in copper oxide in mud, and reaction rate is low, long action time, and product purity is the highest.
In addition, Luo Genxiang etc. prepare Cu-lyt. (CN101928034A) with copper chloride powder and copper powder for raw material in the eutectic solvent that carbamide and choline chloride are mixed to form, the method, to the dissolving of some reactants is limited and liquid temperature scope is little, limits the pure eutectic solvent range of application as reaction dissolvent.Ying Tao opens etc. and to utilize ionic liquid to prepare Cu-lyt. (CN100513315C), the method is to add the raw material in ionic liquid to react, thus reduce the pollution to environment, and can recycle after ionic liquid is separated, but because producing the problems such as garbage in ionic liquid preparation cost, biodegradability and preparation process, its green still suffers from dispute.Wang Baoluo etc. use hydrothermal reduction method to prepare Cu-lyt. (CN1235806C), the method is copper sulfate and sodium chloride to be made into mixed solution regulation acidity proceed to pressure-resistant corrosion-resistant reactor, add excess red copper powder, heating refluxes, add hydrochloric acid after reaction completely and make Cu-lyt., but the method due to the hydro-thermal method i.e. High Temperature High Pressure of feature own thus makes it have the biggest danger.Therefore exploitation a kind of simple to operate effectively, energy consumption is relatively low and eco-friendly method carrys out synthesizing chlorinated cuprous be very important.
