Title: Preparation of 3-trifluoromethylpyridine
Inventor: NISHIYAMA RIYUUZOU
IPC: C07D213/26
Filed: 1979-04-06
Abstract: PURPOSE: To produce 3-trifluoromethylpyridine, useful as a raw material for organo- synthetic chemical industries, economically, in an industrial scale, by reducing a specific chloro-3-trifluoromethylpyridine derivative.  
     CONSTITUTION: 3-Trifluoromethylpyridine is prepared by reducing one or more chloro-3-trifluoromethylpyridine compounds selected from 2-chloro-3-trifluoromethylpyridine, 2-chloro-5-trifluoromethylpyridine and 2,6-dichloro-3-trifluoromethylphridine. The reduction can be carried out under ordinary conditions, i.e. substitution reaction of a halogen with hydrogen. For example, the raw material is catalytically reacted with H 2  gas in the presence of a Ni catalyst. As trifluoromethyl does not decompose and only Cl is selectively substituted with H, the desired compound can be obtained in high yield.

Abstract: PURPOSE:To listen to the content many times in repeating the content failed to hear by detecting a repetitive waveform from a reception signal at reception of broadcast and excluding it so as to record the reception signal with compression on a time axis, reproducing the content of record when a reqproduction request exists and continuing the compression recording of the received content even during the reproduction. CONSTITUTION:After digital signal outputted from an A/D converting circuit 5 is coded by an encoder circuit 6, the signal is supplied to a control circuit 7. The control circuit 7 checks a detection signal 75 from a repetitive waveform detection circuit 12 so as to discriminates whether or not a wave is the repetitive waveform and whether or not the said voice waveform is omitted. If it is discriminated that a wave is omitted, the data is thrown away without being stored. The digital signal subject to reproduction voice output by an A/D converting circuit 10 is reproduced via a changeover switch 11, an amplifier circuit 3 and a speaker 4. Then the data memory is reproduced and the broadcast content during broadcast at present is recorded through compression. Since the recording sound volume is reduced gradually, the state is switched and connected automatically to the original broadcast reception state without intermission of broadcast content.
