- Production method as reducing agent JP-A-58-222038, reduction with potassium acetate in the presence of alcohol (Japanese Patent No. 135722), reduction with Na amalgam (Japanese Patent No. 164954). It has been known. Both reduction methods have disadvantages such as difficult reaction control and high cost.
- JP-A-1149739, JP-A-11319440, JP-A-1-319441 Also known are methods of reducing with hydrogen in the presence of a hydrogenation catalyst (JP-A-1149739, JP-A-11319440, JP-A-1-319441), but the yield is low, and both reduction methods are industrial. It was not a preferable method.
- An object of the present invention is to provide a method for producing 1,1-dichloro-1,2,2,2-trifluoroethane by catalytic reduction which does not cause the above-mentioned problems.
- the gist of the present invention is to provide 1,1,1 trichloro-2,2,2 Rifluoretane is reduced by hydrogen in the presence of a hydrogenation catalyst in which at least one metal selected from the group consisting of silver, copper, gold, tellurium, zinc, chromium, molybdenum and thallium is added to platinum.
- 1,1-dichloro-2,2,2-trifluoroethane The inventor of the present invention has proposed a method for reducing 1,1,1-trichloro-2,2,2-trifluoroethane, particularly in catalytic reduction, because the reduction of chlorine atoms proceeds excessively and causes a reduction in yield.
- the characteristics of its component elements vary depending on the alloy composition.
- the amount of the added metal is from 0.01 to 500% by weight, particularly from 0.1 to 300% by weight, based on platinum.
- the concentration of the alloy on various carriers is as wide as 0.05 to 5% by weight.
- the carrier of the alloy catalyst includes, for example, activated carbon, alumina.
- the particle size of the carrier has little effect on the reaction
- 0.1 to 100 mm is preferred.
- the stoichiometric amount of hydrogen is used to remove the halogen atoms. Total moles of starting material On the other hand, much higher than stoichiometric amounts, for example 4 moles or more of hydrogen may be used.
- As the reaction pressure normal pressure or a pressure higher than normal pressure can be used.
- the reaction temperature is 0 to 450 ° C, preferably 50 to 300 ° C, and the reaction is suitably performed in a liquid phase or a gas phase.
- the contact time is usually 0.1 to 300 seconds, particularly 1 to 30 seconds when the reaction is carried out in the gas phase.

After reaching the specified temperature, the nitrogen gas flow was stopped and the previously vaporized 1,1,1-trichloro-2,2,2-trifluoroethane was removed by 32.8 ccZ and hydrogen was removed. It was introduced at a rate of 65.8 cc / min. The reaction temperature was 130 ° C. The resulting gas was washed with water, dried over calcium chloride, and analyzed by gas chromatography. Table 1 shows the results.
