    摘要: A process for the preparation of .alpha.-methylsubstituted ketones by reacting the corresponding non-methylsubstituted ketones with formaldehyde under hydrogenating conditions. The reaction proceeds easily and with good yields if a catalyst containing metallic palladium deposited on a zirconium, hafnium, titanium or tin phosphate is used. The products are valuable intermediates for the preparation of dyes, crop protection agents or drugs.

    摘要: A switching device includes a movable switching element and an electrical switch in operative connection to the switching element. The switching element is operable to selectively separate the operative connection between the switching element and the electrical switch. The interaction between the switching element and the electrical switch can be blocked. Also, an arrangement for detecting at least two different positions of a mobile door element is provided, wherein an interaction between the door element and the switching element can also be blocked. The inventive arrangement and switching device are especially suitable for using in household appliances such as electrical refrigerators or cooking appliances.
