text: The revolutionaries knew that hydrocyanic acid produced a very toxic gas and that an antidote would need to be available if those manufacturing it were not to suffer.
text: It has now been found that hydrogen cyanide or hydrocyanic acid can be produced from liquified gases and ammonia without disturbing the operation through deposition of carbon black under the conditions of the hydrocyanic acid-methane-ammonia process and by producing it in the apparatus belonging to such process, if there is used as the hydrocarbon propane or butane, or any mixture of the two and if the reaction is carried out in the presence of additional hydrogen at an atomic ratio of carbon to nitrogen to hydrogen of 1:1:7.1 to 1:1.33:13 at the beginning of the reaction with reaction conditions known of themselves and the hydrogen cyanide formed is recovered from the gaseous reaction mixture with the help of the likewise known process of working up, whereupon, in a given case, hydrogen containing residual gas is partially returned again into the reaction steps.
