Abstract: The voltage controlled oscillator has a feedback stage for maintaining the correct phase, containing a threshold amplifier (30) and a parallel switch stage containing a comparator (44) and a second threshold amplifier (46). The comparator (44) has one input coupled to the input of the first threshold amplifier (30) and a secondinput coupled to the output of the second threshold amplifier (46) which is also fed back to the input of the latter. It acts as a reference voltage generator providing a reference voltage which is the same as the threshold voltage of the first threshold amplifier (30). Both threshold amplifiers (30,46) have the same transistor configuration with the transistors sized differently.

In a first step, a suspension of potassium carbonate is obtained in the inert liquid. In a second step, the metal or metals (M), and optionally copper, are introduced in powder form into the highly stirred reaction medium. In a third step, after bringing the reaction medium to a temperature higher than the potassium melting temperature, potassium is introduced under high stirring conditions. In the fourth step, the reaction medium is brought to a temperature comprised between 140 and 180 DEG C during a length of time comprised between 1 and 3 hours, and the reaction medium is then allowed to cool down to room temperature. The process for dimerization of propylene into methyl-4-pentene-1 uses the catalyst disclosed hereabove.
