Definitions
- the present invention relates to a method for collecting cumene. More specifically, the present invention relates to a method for recovering cumene, which efficiently recovers 2,3-dimethyl-2,3-diphenylbutane produced in a process using cumene as cumene. Background art
- cumene is used as cumene hydroperoxide
- a process for obtaining phenol and acetone by acid decomposition of the cumene hydroperoxide is known.
- an undesirable side reaction is the reaction of cumene dimerizing to give 2,3-dimethyl-2,3-diphenylbutane.
- the by-product of 2,3-dimethyl-2,3-diphenylbutane consumes cumene and causes undesirable phenomena, such as interfering with the desired reaction. Disclosure of the invention
- An object of the present invention is to provide a method for efficiently recovering 2,3-dimethyl-1,2,3-diphenylbutane produced in a process using cumene as cumene.
- the present invention provides a process for recovering cumene, characterized in that, in a process using cumene, the produced 2,3-dimethyl-2,3-diphenylbutane is hydrocracked in the presence of a catalyst and converted into cumene to be recovered. Pertains to the method. The best form to apply the invention
- cumene is used as cumene hydroperoxide, and a process including a step of obtaining propylene oxide from the cumene hydroperoxide and propylene, or cumene is used as a cumene hydroxide peroxide.
- a process for obtaining phenol and acetone by acid decomposition of hydroperoxide can be mentioned.
- the produced 2,3-dimethyl-2,3-diphenylbutane is hydrocracked in the presence of a catalyst, and is converted to cumene and recovered.
- a catalyst containing a metal of Group 10 or Group 11 of the periodic table (IUPAC revised edition of inorganic chemical nomenclature (1989)) is preferable.
- the metal is preferably at least one selected from the group consisting of copper, palladium, platinum and nickel. From the viewpoint of suppressing by-products, it is preferable to use a copper-based catalyst.
- Copper-based catalysts include copper, Raney copper, copper, chromium, copper 'zinc, copper-chromium-zinc, copper-silicon, copper-alumina, and the like.
- the hydrocracking reaction can be carried out in the liquid or gas phase.
- the hydrocracking reaction temperature is generally 0 to 500 ° C, but preferably 30 to 400 ° C. In general, it is advantageous for the pressure to be between 100 and 1000 kPa. Hydrogen may be present in an amount of at least equimolar to 2,3-dimethyl-2,3-diphenylbutane.
- the hydrocracking reaction can be advantageously carried out using a slurry or a catalyst in a form suitable for a fixed bed.
- the process according to the invention can be carried out by a batch, semi-continuous or continuous process.
- the process using cumene is a process that includes the step of obtaining propylene oxide from cumene hydroperoxide and propylene.
- the hydrogen cracking reaction must be performed after separating and removing propylene oxide from the reactants. Is preferred.
- Cumyl alcohol produced in the process of obtaining propylene oxide from cumene hydroperoxide and propylene is converted into cumene by hydrogenolysis.If it is necessary to recover cumyl alcohol as cumene, use cumyl alcohol. It is also possible to carry out the hydrocracking reaction with the reaction solution containing If cumyl alcohol is not desired to be hydrocracked, the hydrocracking reaction can be carried out after separating and removing cumyl alcohol.
- a hydrocracking reaction After separating and removing cumyl alcohol, a hydrocracking reaction can be carried out. Performing the hydrogenolysis reaction after separating or removing 2,3-dimethyl-2,3-diphenylbutane from the viewpoint of minimizing the side reaction of the active ingredient such as cumenecumyl alcohol. preferable.
- the process using cumene is a process to obtain phenol and acetone by acid decomposition of cumene hydroperoxide
- hydrogenation of acetone should be performed in order to minimize the amount of nucleus hydrogenation of phenol. It is preferable to carry out the hydrocracking reaction after separating and removing acetone, phenol and phenol.
