Abstract
The known hydrocyanic acid-methane-ammonia (BMA) process for the production of hydrogen cyanide can now be carried out with liquified gases namely through the presence of additional hydrogen at the beginning of the reaction. The atomic ratio of carbon to nitrogen and hydrogen is from 1:1:7.1 to 1:1.33:13. As additional hydrogen there is the portion of hydrogen present coming out of the reaction "hydrocarbon+NH.sub.3 ". Otherwise the reaction conditions are the same as in the known BMA process.
Claims13
In a process for the production of hydrogen cyanide or hydrocyanic acid from liquified gas and ammonia according to the conditions of the hydrocyanic acid-methane-ammonia process in a reaction zone, the improvement comprising employing in place of methane a hydrocarbon consisting essentially of propane or at least one butane or a mixture of propane and at least one butane the gaseous mixture consisting essentially of the propane and/or butane, ammonia and hydrogen to provide 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 and separating the hydrogen cyanide from the reaction gas mixture.
