Description

Verfahren zur Ausscheidung der in der Nitriersäure gelösten Nitrierungsprodukte der ungesättigten, gasförmigen Kohlenwasserstoffe. Das Hauptpatent betrifft ein Verfahren zur Ausscheidung der in der Nitriersäure gelösten Nitrierungsprodukte der ungesättigten gasförmigen Kohlenwasserstoffe durch Auflösen von Ammoniumsulfat, Ammoniumnitrat oder anderen geeigneten Ammoniumsalzen in der als Nitriersäure verwendeten Mischsäure. Es wurde nun gefunden, daß man außer den Ammoniumsalzen eine ähnliche Wirkung erzielt, wenn man in der Mischsäure Natriumsalze auflöst. Da jedoch die Natriumsalze in der Mischsäure von Salpeterschwefelsäure hoher Konzentration nicht löslich sind, so ist es notwendig, die Mischsäure vor dem Auflösen der Natriumsalze etwas mit Wasz er zu verdünnen, und zwar versetzt man zweckmäßig einen Teil Mischsäure mit zwei Teilen Wasser. Als Natriumsalze verwendet man am besten Natriumsulfat oder Natriumbisulfat, doch kann man ebenfalls Natriumnitrat und andere geeignete Natriumsalze benutzen, nicht aber Natriumchlorid, da hierdurch gasförmige Salzsäure in Freiheit gesetzt wird:Process for eliminating the nitration products dissolved in the nitrating acid of unsaturated, gaseous hydrocarbons. The main patent concerns a Process for eliminating the nitration products dissolved in the nitrating acid the unsaturated gaseous hydrocarbons by dissolving ammonium sulphate, Ammonium nitrate or other suitable ammonium salts in the one used as the nitrating acid Mixed acid. It has now been found that, in addition to the ammonium salts, a similar one can be used Effect achieved by dissolving sodium salts in the mixed acid. However, since the Sodium salts in the mixed acid of nitric sulfuric acid of high concentration are not Are soluble, so it is necessary to add the mixed acid before dissolving the sodium salts To dilute a little with water, it is advisable to add a part of mixed acid with two parts of water. The best sodium salts used are sodium sulfate or Sodium bisulfate, but sodium nitrate and other suitable sodium salts can also be used use, but not sodium chloride, as this releases gaseous hydrochloric acid is set:
