  • Patent number: 4367178
    Abstract: Disclosed is a process for the production from raw lecithin of pure lecithin directly usable for physiological purposes, comprising the steps of contacting raw lecithin with gas as the extraction medium under supercritical conditions with respect to pressure and temperature in an extraction stage to produce a gas containing an extract; passing the gas containing the extract from the extraction stage into a separation stage; varying at least one of the pressure and the temperature of the gas in the separation stage to separate the extract-containing gas into the gas and the extract; recycling the gas after the step of varying the pressure and/or temperature; and removing pure lecithin from the extraction stage.

  • Patent number: 4170649
    Abstract: New 1,4-benzodiazepine derivatives are disclosed which are substituted in 2-position by cyanomethylene or carbamoylmethylene and have the formula ##STR1## wherein R.sub.1 represents hydrogen, halogen, or nitro, R.sub.2 represents hydrogen or lower alkyl, R.sub.3 represents phenyl which may be substituted by halogen or CF.sub.3, and R.sub.4 represents cyano or carbamoyl. The compounds exhibit tranquilizing activities. The cyanomethylene-compounds are prepared by oxidizing corresponding cyanomethyl compounds with Cr-VI-oxide in an acidic reaction medium. The cyanomethylene-group can subsequently be hydrolyzed into the carbamoylmethylene group.
