« on: April 30, 2002, 01:41:00 PM »

Patent US4638094



Abstract :

Example 1

A 0.10 mole amount of the starting 3-phenylpropylene 0.25 mole of methyl nitrite, 0.5 liter of methyl alcohol, 36 g of water, and 0.008 mole (1.42 g) of a palladium chloride catalyst were charged into a reaction vessel. Then, the reaction was carried out at a temperature of 25.degree. C. for 2 hours.

After completion of the reaction, the reaction mixture was gas chromatographically analyzed to quantitatively determine the amounts of the unreacted starting material and the resultant desired product. As a result, the conversion of the starting material was 100% and the yield of the desired product (phenylacetone) was 90%.

Example 2

Phenylacetone was prepared in the same manner as in Example 1, except that n-butyl nitrite and n-butyl alcohol were used in lieu of methyl nitrite and methyl alcohol and that the reaction temperature was changed to 55.degree. C.

After completion of the reaction, the unreacted starting material and the desired product were quantitatively analyzed as in Example 1. The conversion of the starting material was 100% and the yield of the desired product was 87%.

I was just illustrating its use for the production of phenylacetone as well.

But you are quite right foxy, the patent is mentioned here for the production of MDP-2-P :

Could a catalyst of platinum, on a carbon support, with a ptfe binder be used instead of palladium chloride ?

(the type sold for DIY fuel cell anodes)
