The present invention relates to a method for producing methyl isobutyl ketone. More specifically, it relates to a method for directly converting diacetone alcohol to methyl isobutyl ketone. Conventionally, methyl isobutyl ketone (hereinafter referred to as MIBK)
) is acetone (hereinafter abbreviated as ACT), diacetone alcohol (hereinafter abbreviated as DAA) is made using an alkali such as barium hydroxide as a catalyst, and DAA is dehydrated using an acid as a catalyst to produce mesityl oxide (hereinafter abbreviated as mesityl oxide). It is produced by hydrogenating MO. However, these methods are complicated and involve a three-step reaction process, and cannot be said to be industrially satisfactory. An object of the present invention is to simplify the above-described complicated steps and provide a method for producing MIBK in two steps. That is, the objective is to provide a method for directly converting DAA produced from ACT into MIBK. The present inventors have conducted intensive studies on a method for directly converting DAA to MIBK, and found that DAA can be easily converted into MIBK by contacting it with hydrogen gas in the coexistence of an acid catalyst and a reduction catalyst.
It became clear that it can be converted to MIBK, leading to the present invention. That is, the present invention is a method for directly converting diacetone alcohol into methyl isobutyl ketone, which is characterized by contacting liquid diacetone alcohol with hydrogen gas in the coexistence of an acid catalyst and a reduction catalyst. Therefore, the method of the present invention described above is applicable to DAA
MIBK is manufactured directly from
Compared to the production method, the reaction process can be shortened by one step, making it an extremely advantageous method industrially. In the method of the present invention, MIBK directly from DAA
can be obtained with a high selectivity of 92 to 98%, and only a small amount of isopropyl alcohol, methyl isobutyl carbinol, and acetone are produced as by-products. DAA is synthesized by the condensation reaction of ACT, and the DAA concentration after the condensation reaction is approximately 12 to
It is 15% by weight. In the method of the present invention, DAA (12 to 15% by weight) after the condensation reaction may be used,
In addition, once the DAA concentration was measured, the concentration DAA (approximately 80
weight%) may be used. In the present invention,
ACT may also be fed to the reactor along with DAA;
Hydrogenation of ACT can be kept to an extremely small amount. The acid catalyst used in the method of the present invention may be any conventional one, but solid acids and/or strongly acidic ion exchange resins are preferred. Examples of solid acids include HY type zeolite, silica-alumina, etc., and examples of strong acidic ion exchange resins include Amberlyst-15,
Duolite-C-26H etc. are exemplified. Also, common reduction catalysts may be used, such as Raney-nickel, copper-chromium, Pd/Al 2 O 3 , Pd/C, Pt/
Examples include Al 2 O 3 , Pt/C, etc., but the production MAIBK
In the sense of avoiding hydrogenation of ACT and ACT as much as possible, noble metal element catalysts such as Pd and/or Pt having low temperature activity are particularly preferred. Note that the mixing ratio of the acid catalyst and the reduction catalyst is arbitrary. The reaction temperature is 40
It can be carried out in the range of ~200℃, but usually
60-150°C is chosen as the preferred temperature range.
If the reaction temperature is less than 40℃, sufficient reaction rate cannot be achieved, and if the reaction temperature exceeds 20℃, ACT
and MIBK hydrogenation occurs considerably, leading to a decrease in yield. The reaction pressure can be in the range of 1 to 50/cm 2 G, but 20 kg/cm 2 G is usually selected as the preferred reaction pressure range. The reaction method may be a batch method or a fixed bed flow method. In the fixed bed flow type, the mixing ratio of DAA and hydrogen gas is in the range of 1 to 0.1 (DAA/hydrogen gas) molar ratio, and the liquid hourly space velocity (LHSV) of DAA is usually 0.05 to 0.1. A range of 10 is used. Next, the present invention will be specifically explained with reference to Examples, but the present invention is not limited to these in any way. Example 1 100g of reagent DAA in a 200ml SUS autoclave,
When 5% Pd/Cg1 and 1 g of Amberlysto 15 were charged and the reaction was carried out at a reaction temperature of 120° C. and a hydrogen pressure of 10/cm 2 G, a predetermined amount of hydrogen absorption was observed in about 80 minutes. When the reaction solution was analyzed by gas chromatography, the conversion rate of DAA was 94.9%.
Also, the selectivity to MIBK is 92.8%, the selectivity to isopropyl alcohol is 0.40%, the selectivity to methyl isobutyl carbinol is 2.6%, and the selectivity to ACT is 4.5.
It was %. Example 2 Duolite C instead of Amberlyst 15
When the reaction was carried out in the same manner as in Example 1 except for using -26H, a predetermined amount of hydrogen absorption was observed in about 75 minutes. When the reaction solution was analyzed by gas chromatography, the conversion rate of DAA was 97.9%. or,
Selectivity to MIBK is 92.3%, selectivity to isopropyl alcohol 0.85%, selectivity to methyl isobutyl carbinol 3.33%, selectivity to ACT 3.51%.
It was hot. Example 3 A reaction was carried out in the same manner as in Example 1 except that 0.5 g of HY-type zeolite catalyst was used in place of Amberlyst 15. The reaction result was a conversion rate of DAA of 87.7.
%, selectivity to MIBK 92.8%, selectivity to isopropyl alcohol 0.59%, selectivity to methyl isobutyl carbinol 3.76%, selectivity to ACT 2.81
It was %. Example 4 Using DAA containing 20% by weight of ACT, the rest is Example 2
The reaction was carried out in the same manner. When the reaction solution was analyzed by gas chromatography, the DAA conversion rate was 96.8%. Also, the selection rate for MIBK was 96.2%, and the selection rate for ACT was 2.57%. Example 5 The catalyst used in Example 4 was recycled and the same reaction as in Example 4 was repeated four times. The results of DAA conversion rate and MIBK selectivity are shown in Table 1.
