Title: Dimerization catalyst of lower alpha-olefin
Inventor: NAKAGAWA KANJI
IPC: C07C11/02
Filed: 1994-01-25
Abstract: PURPOSE:To obtain a catalyst having good selectivity while keeping activity by using an arihydrous potassium compd. composed of a mixture of potassium fluoride and potassium carbonate as a carrier and setting the specific surface area of the carrier to a definite value or more. CONSTITUTION:A catalyst for producing a dimer or co-dimer of lower alpha-olefin is obtained by supporting an alkali metal on a compression molded granular carrier consisting of an anhydrous potassium compd. and carbon. As the anhydrous potassium compd., a mixture of potassium fluoride and potassium carbonate is used. The specific surface area of the compression molded granular carrier is set to 0.25m<2>/g or more. This catalyst is improved in the selectivity to an objective product while keeping activity and, when this catalyst is used in the production of 4-methylpentene-1 by the dimerization of propylene, the formation of 4-methylpentene-2 being an isomer hard to separate is reduced.

Filed: 1986-01-18
Abstract: PURPOSE:To reduce the probability of the drive stop of an antenna by placing the antenna is search driving operation without stopping the driving when the reception level of the antenna drops below a traceable level. CONSTITUTION:The output of a receiver 9 is applied to an integrator 3 through a low-pass filter 2 and integrated for a certain time while the antenna is stationary, and the integral output is sampled 4, A/D-converted, and stored 5. An arithmetic processing part 6 calculates the difference in integral level between received signals before and after the antenna is driven and judges whether the difference is positive or negative to send a control signal to a driving device 10. When the reception level drops below an automatic tracking stop level, a stop level decision circuit 8 operates, but even when the circuit 8 decides that the reception level is below the traceable level, the automatic tracing is not stopped by the arithmetic processing part 6 and the antenna 1 is driven to the periphery to search for a traceable level. Then, when the reception level rises above the traceable level, the automatic tracing is carried on as it is.
