Description
Technical Field
The invention relates to a method for preparing o-diol by oxidizing olefin, in particular to a method for preparing o-diol by oxidizing olefin under the co-catalysis of a titanium silicon molecular sieve and a tungsten-containing compound.
Background
Vicinal diols refer to hydrocarbon organic compounds in which hydroxyl groups are present in each of the adjacent two carbon atoms. Common vicinal diols include 1, 2-ethanediol (hereinafter abbreviated as ethanediol), 1, 2-propanediol (hereinafter abbreviated as propanediol), 1, 2-butanediol (hereinafter abbreviated as butanediol), 1, 2-hexanediol (hereinafter abbreviated as hexanediol), and the like. The vicinal diols have important uses, for example, ethylene glycol can be used as a solvent, an antifreezing agent, synthetic polyester, etc., propylene glycol can be used as an unsaturated polyester resin, as an antifreezing agent, a humectant, etc., and hexylene glycol can be used for the production of high-end cosmetics, etc. The o-glycol has wide market application, and the yield is larger, and the global propylene glycol yield in 2018 reaches 180 ten thousand tons/year by taking propylene glycol as an example.
The main production method of the vicinal diols is obtained by hydrolyzing the upstream epoxy compounds under certain conditions. For example, ethylene oxide is hydrolyzed to obtain ethylene glycol, propylene oxide is hydrolyzed to obtain propylene glycol, and hexane is hydrolyzed to obtain hexylene glycol, etc. In addition, the propylene glycol can also be obtained by a dimethyl carbonate/propylene glycol co-production method. The method for hydrolyzing the epoxy compound must prepare the epoxy compound first, and the whole flow brings the problems of increased process complexity, low raw material utilization rate and three wastes discharge, which directly leads to increased cost. The co-production method also requires the production of the epoxy compound first, and in addition, the price of the co-production product is always affected by market fluctuation.
US10214471 and US20180354878A1 disclose a method for obtaining propylene glycol by reacting propylene and hydrogen peroxide in a reactor under the action of a heteropolyacid and a phase transfer catalyst. In the method, heteropolyacid and hydrogen peroxide form heteropolyacid peroxide salt in a water phase, and organic phase soluble salt is formed by the phase transfer catalyst and the heteropolyacid peroxide salt. In the method, an alkylated aromatic organic solvent having 8-12 carbon atoms increases the proportion of heteropolyacid salt in the organic phase to complete the oxidation of propylene to propylene oxide. The heteropolyacid is dissolved in water to continuously act with hydrogen peroxide, and the generated propylene oxide can enter into a water phase, and the propylene oxide is hydrolyzed under the action of water phase acid to obtain propylene glycol because the pH value of the water phase is maintained within the range of 1-3.5. The method is actually only to carry out two-step reaction of propylene epoxidation to propylene oxide, wherein the propylene oxide is hydrolyzed and ring-opened to propylene glycol under the action of acid in one reactor, a large amount of solvent is needed in the reaction process, the catalyst system is complex, and the operation difficulty is high.
EP1527057A1 discloses a process for the continuous preparation of propylene glycol. Propylene and hydrogen peroxide react to generate propylene oxide, propylene glycol is produced as a byproduct, the generated propylene oxide is reacted at 180-220 ℃ and 15-25bar to generate propylene glycol, and the propylene glycol is obtained after separation. The method is the physical integration of two-step reaction of epoxidation and hydrolysis, and cannot avoid the problems of low reaction efficiency and severe hydrolysis treatment conditions.
WO2019029808A1 discloses a process for preparing terminal 1, 2-alkanediols having from 5 to 12 carbon atoms by mixing the corresponding terminal alkene with formic acid and hydrogen peroxide to give the mono-or di-formate, and decomposing the mono-or di-formate under the action of a decarbonizing catalyst to give the corresponding diols and carbon monoxide. The method has low selectivity and high safety risk of the organic peroxide.
CN103570493a discloses a method for synthesizing 1, 2-o-diol by solid-supported heteropolyacid phase transfer catalytic oxidation, which is characterized in that acid, terminal alkene, hydrogen peroxide and heteropolyacid phase transfer catalyst are mixed and reacted, then separated to obtain an epoxidation mixture, then alkali liquor is added to maintain the pH value of 10-12, and then the o-diol is obtained by extraction with ester and reduced pressure distillation. The method has long operation flow and low product yield.
CN107879893a discloses a method for preparing an ortho-diol compound by catalytic oxidation, which is to prepare ortho-diol under the action of olefin, oxidant and bifunctional catalyst, wherein the bifunctional catalyst contains silicoaluminophosphate molecular sieve, alumina and titanium silicalite molecular sieve. The method uses an aluminum-containing catalyst, and the utilization rate of hydrogen peroxide is low.
CN102452899a discloses a method for preparing propylene glycol from propylene, which is to perform epoxidation ring-opening hydration reaction on titanium-silicon molecular sieve composite catalyst, propylene and hydrogen peroxide to prepare propylene glycol, wherein the titanium-silicon molecular sieve composite catalyst comprises titanium-silicon molecular sieve, acidic molecular sieve and resin. The method has low hydrogen peroxide utilization rate.
CN104447204a discloses a method for preparing glycol, which uses a titanium silicon molecular sieve loaded with rare earth oxide as a catalyst to promote the reaction of olefin and oxidant to generate glycol. The method has low hydrogen peroxide utilization rate.
