Definitions

  • the present invention relates to a process for oxidizing olefins containing at least 3 carbon atoms to aldehydes and ketones.
  • ketones are almost exclusively obtained (see Angewandte Chemie, 1959, vol. 71, page 179).
  • propylene is oxidized in the aforesaid manner, only 1 part of propionaldehyde is obtained per 200 parts of acetone formed, and the oxidation of butene-l yields only about 0.5% of butyraldehyde calculated on the methylethylketone formed.
  • the quantity of aldehyde formed in the first 2 to 3 hours is larger but it then drops to the aforesaid values given as examples.
  • the portion of aldehyde formed can be considerably enlarged as compared with ketone, by using a catalyst which contains, per liter of catalyst, more than about 0.5 mol of a noble metal salt, advantageously palladium chloride, in addition to a salt, advantageously the halide, of such metals as are capable of forming several stable valence stages.
  • a noble metal salt advantageously palladium chloride
  • a salt advantageously the halide
  • the amount of noble metal salt to be added according to the invention shall exceed 0.25 mol, which corresponds, for example, to 45 grams PdCl per liter of catalyst and shall be advantageously above 0.5 mol, which corresponds to about 90 grams PdCl per liter of catalyst.
  • the upper limit is given by the solubility of the noble metal compound at the working temperature used.
  • the ratio of aldehyde to ketone may, however, become again unfavorable.
  • the catalyst shall also contain a redox compound, for example a copper or iron salt, as described in the aforesaid specification.
  • the formation of aldehyde increases with the amount of noble metal compound added and with the temperature.
  • higher temperatures favor the formation of aldehyde only when the minimum quantity of noble metal compound to be added according 3,215,743 Patented Nov. 2, 1965 to the invention is used.
  • an elevated pressure may, how ever, also be advantageous at lower temperatures.
  • the ratio of propionaldehyde formed to acetone formed is, for example, as follows:
  • the catalyst used may be solid or liquid. If in catalysts containing halogen compounds losses in halogen occur, the lost proportion has to be replaced, for example, by the addition of hydrochloric acid.
  • the process may be carried out in a liquid or solid phase, for example, in the manner described in the aforesaid copending patent, applications or in commonly owned copending U.S. patent application Ser. No. 855,975 filed on November 30, 1959 (now US, 3,119,874 granted January 28, 1964), and under the conditions described therein.
  • compounds yielding anions for example hydrogen chloride
  • the process may be carried out at a temperature within the range of 20 to 200 C. or more, preferably at a temperature ranging from 50 to 170 C.
  • EXAMPLE 1 A reaction tube in upright position was charged with 100 cc. of an aqueous catalyst containing 100 grams of PdCl and 400 grams of CuCI ZH O per liter of liquid. 4 liters of propylene and 1 liter of oxygen were then introduced per hour into the catalyst through a frit and the acetone and propionaldehyde which formed were isolated by a water wash. At a temperature of 85 C., propionaldehyde and acetone were obtained in a ratio of 1:42; at 100 C. in a ratio of 1:3.6; at 120 C. and 1 atmosphere gage in a ratio of 1:29. In the last instance, the conversion of propylene to the sum of aldehyde ketone amounted to 23%, calculated on the propylene which had been put through. The gases that had not been reacted could be returned to the process and re-used.
  • Example 2 The apparatus of Example 1 was charged with 100 cc. of catalyst liquid containing, per liter, grams of PdCl and 320 grams of CuCl .2H O and the process was carried out as described in Example 1.
  • the ratio of propionaldehyde to acetone was 1:7.2 at 20 C.; 1:43 at 85 C., 1:3.5 at 100 (3.; 1:20 at 120 C.
  • Example 3 The apparatus of Example 1 was charged. with an aqueous catalyst solution containing, per liter, 220 grams of PdCl and 440 grams of CuCl .2H O and the process was carried out as described in Example 1. Propionaldehyde and acetone were obtained at 85 C. in a ratio of 1:4.0.
  • Example 4 The apparatus of Example 1 was charged with 100 cc. of a catalyst containing, per liter, 160 grams of PdCl and 320 grams of CuCl .2H O. A mixture of 4 liters/ hour of butene-l and 1 liter/hour of oxygen was introduced into the catalyst liquid. The ratio of butyraldehyde t-o methylethylketone was 1:11 at 20 C.; 1:6.7 at 85 C.; 124.8 at 100 C.
  • EXAMPLE 5 A long reaction tube 30 mm. in diameter and provided with a heating jacket was charged with 200 cc. of active carbon which was impregnated with a solution of 40 grams of CuCl .2H O and increasing amounts of PdCl Water which was constantly kept at 85 C. with the help of a thermostat was passed through the heating jacket. A mixture of 20 liters/ hour of propylene and 40 liters/ hour of air was conducted through an evaporator disposed before the reaction tube and then in a downward direction through the catalyst. Into the evaporator which Was heated by means of an oil bath, ce/hour of 011 N- hydrochloric acid were introduced dropwise at a uniform rate, evaporated and introduced into the catalyst together with the gas current.
  • the reaction mixture leaving the reaction tube was freed from water in a cooler and samples were continuously taken in order to be analyzed by gas-chromatography.
  • the carbonyl compounds, propionaldehyde and acetone, which. had been formed were isolated from the reaction mixture by washing with water and finally a remainder of the said carbonyl compounds was absorbed with hydroxylamine.
  • the concentration of propionaldehyde in the reaction product increased as the content of PdCl in the catalyst was increased, i.e., from 1.6% of propionaldehyde at a PdCl content of 2 grams to 12.4% of propionaldehyde at a PdCl content of 20 grams.
  • the following table clearly shows the shift from ketone t-o aldehyde occurring in the reaction product in dependence on the PdCl content of the catalyst.
  • EXAMPLE 7 A mixture of 7.5 liters of propylene and 30 liters of air was introduced per hour, at 85 C., into a catalyst solu tion of 50 grams of PdCl and 200 grams of CuCl .2H O in 500 cc. of water to which 10 cc. of concentrated hydrochloric acid had been added.
  • the reaction mixture was examined in a manner analogous to that described in the preceding examples. It contained 14% of propionaldehyde, calculated on acetone, in the first 24 working hours. The portion of aldehyde then gradually dropped by about 50% and maintained that value in a permanent test lasting 600 hours.
  • EXAMPLE 8 A heatable tube 10 mm. in diameter was charged with 30 cc. of silica gel which was impregnated with 10 cc. of a solution of 250 grams/liter of CuCl .2H O and varying amounts of PdCl per liter. 'The reaction temperature was about C. 2 normal liters (N.T.P.) of propylene and 1 normal liter (N.T.P.) of oxygen were introduced per hour. The oxygen-containing compounds which had formed, particularly acetone and propionaldehyde, were isolated from the gas mixture leaving the reaction zone by washing with water.
