Description
Technical field
The present invention relates to a kind of method for preparing pimelinketone.
Background technology
Pimelinketone is an important chemical material, is mainly used in outside the monomer of polymeric amide (nylon 6 and nylon-66) such as producing hexanolactam, hexanodioic acid, also is widely used in industry such as fiber, synthetic rubber, technology coating, medicine, agricultural chemicals, organic solvent.The method of traditional mode of production pimelinketone is with producing cyclohexane by adding hydrogen in benzene, again it catalyzed oxidation is made hexalin, pimelinketone, perhaps phenol hydrogenation is produced hexalin, obtains pimelinketone through catalytic dehydrogenation again.CN1847206A has reported the method for phenol hydrogenation synthesizing cyclohexanone, and CN1793099A is an oxygenant with the hydrogen peroxide, and the catalyzed oxidation hexalin makes pimelinketone in organic solvent.At present, the main method of producing pimelinketone both at home and abroad is a cyclohexane oxidation process, and is wherein important with the catalyzed oxidation of hexanaphthene again.At present, the industrial route that cyclohexane oxidation is produced pimelinketone has two, and the one, the hexanaphthene catalyzed oxidation, another is the non-catalyst oxidation of hexanaphthene.It is catalyzer that catalytic oxidation adopts cobalt salt, boric acid or metaboric acid.Problems such as this technology exists conversion of cyclohexane not high (～4%), alcohol ketone selectivity low (about 80%), power consumption is high, environmental pollution is serious.
CN1982273A, CN101293810A has reported at oxidation stage and has adopted supergravity reactor respectively, the processing method of the pimelinketone of the cyclohexane liquid-phase oxidation preparation of microreactor, CN1834078A designs a kind of novel process, be about to hexanaphthene and oxidation products and pass through reactor from bottom to up continuously to be similar to the plug flow pattern, and oxygen-containing gas with and stream mode adopt alkali lye outer circulation and static mixer by reactor CN1253938A at the cyclohexyl hydroperoxide catabolic phase, CN1397538A makes the decomposition of the oxidation mixture that contains cyclohexyl peroxide divide two sections to carry out, and has reduced the consumption of NaOH.These have all more or less solved some above-mentioned difficult problems.Because pimelinketone is than the easier oxidation of hexanaphthene, cyclohexane oxidation process has a large amount of by-product production, in order to reduce the production of by product, improve product selectivity and yield, the researchist must control conversion of cyclohexane, and the residence time of hexalin, pimelinketone, if but transformation efficiency is too low, a large amount of hexanaphthenes have neither part nor lot in reaction, and then the separation costs of product, raw material can strengthen, investment simultaneously is also big, and economic benefit is descended.If overstand, then hexalin, pimelinketone are easily by deep oxidation, and the selectivity and the yield of reaction all descend.
The exploitation of catalyzer and research become improved emphasis, and the eco-friendly cyclohexane oxidation catalyst of development of new becomes the task of top priority.CN1062718A adopts the organic high conductivity polymer molecular clustering of transition metal catalyzer one-step synthesis hexalin, pimelinketone; CN1530358A adopts the reactor and the combination of different structure under catalysis of metalloporphyrin agent effect, obtain hexamethylene alcohol ketone product.But the both is a homogeneous catalysis, the easy blocking pipe of the industrial application of catalyzer.CA1745895A is with the cupric pyrophosphate composite catalyst, be easy to from reaction solution, separate, but wherein the selectivity of tetrahydrobenzene has 0～18.9%, and add siccative CN101817733A to reaction system adopts cobalt to replace Dawson type phosphorus molybdenum-vanadium multi-metal oxygen hydrochlorate as catalyzer, with the hydrogen peroxide is oxygenant, and easy deep oxidation of hydrogen peroxide and utilization ratio are lower.CA1810746A adopts the AlPO-5 molecular sieve catalyst that has supported Ce, CA101747142A adopts nano ferrite to make catalyzer, their all recyclable utilization, environmental friendliness, being easy to reaction system separates, but the low temperature high catalytic activity that does not have nano catalyst will obtain reaction product in 4～10 hours 130～160 ℃ of reactions.CN1781889A adopts micro porous molecular sieve loading Pd or Pt noble metal catalyst, and it is catalyzer that CN1623971A has the silica-based mesoporous molecular sieve of ruthenium with load, and the both has the product separate easily; Environmentally safe need not to use the solvent advantage.CN101204664A has invented a kind of hexanaphthene catalyzed oxidation that is used for and has produced heterogeneous catalyst of pimelinketone and hexalin and preparation method thereof, and cyclohexane conversion reaches as high as 13.02%, but hexalin and pimelinketone selectivity have only 80.43%.
CN101822990A, CN1827213A, what CN101862660A adopted is nano catalyst, to the hexanaphthene better catalytic activity, but what adopt carrier all is metal oxide, and it is the effect of solid acid catalyst that carrier has, and is not pure redox catalyst, and do not utilize molecular sieve pore passage select the shape effect, therefore being used for industrial selectivity can be relatively low.
CN1772723A adopts molecular sieve supported gold (Au/SBA, Au/HMS) catalyzer, and charged pressure is 5～15Mpa, and 120～200 ℃ of temperature were reacted 4～10 hours, and pressure and temp is all higher.It is catalyzer that CN1611476A (Au-MCM-41, Au-SAPO-11, Au-Ti-MCM-41, Au-Pd-MCM-41) has the silica-based molecular sieve of gold with load, 140～160 ℃, charged pressure is the oxygen of 1～3Mpa, and selective oxidation prepared pimelinketone in 4～10 hours under the air tight condition.CA101698153A has invented a kind of nano-noble metal catalyst and preparation method, described support of the catalyst is a mesoporous molecular sieve, catalyst active center is Au/Ag, and it is better to be used for cyclohexane selectively oxidizing process effect, but does not adopt micro porous molecular sieve to carry the catalyzer of gold.
Above the deficiencies in the prior art part: adopt the dioxygen oxidation hexanaphthene, be unfavorable for industrialization, still have energy consumption height and environmental pollution problems.
Summary of the invention
