Description
Die Erfindung betrifft ein Verfahren zur Verringerung der Entzündlichkeit von Wasserstoff. The invention relates to a method for reducing the flammability of hydrogen.
Sie beruht auf der neuen Erkenntnis, daß eine erhebliche Verringerung der Entzündlichkeit des Wasserstoffs durch einen Zusatz von dampfförmigen organischen Verbindungen des Bleis oder Zinns, z. B. von Bleitetramethyl oder Zinntetramethyl, allein oder beide zusammen, herbeigeführt werden kann.It is based on the new knowledge that a significant reduction in inflammability of hydrogen by adding vaporous organic compounds of lead or tin, e.g. B. of lead tetramethyl or tin tetramethyl, alone or both together, can be brought about.
Es ist bereits vorgeschlagen worden, durch den Zusatz von Dämpfen die Explosionsgrenze und den Flammpunkt von Wasserstoffgas weitgehend zu verändern, wenn die Zusatzstoffe den Bedingungen genügen, daß die Fortpflanzungstemperatur einer Flamme im Dampf des Zusatzmittels höher ist als in reinem Wasserstoff.It has already been proposed to reduce the explosion limit and flash point of hydrogen gas by adding vapors to change largely if the additives meet the conditions that the propagation temperature of a flame is higher in the vapor of the additive than in pure hydrogen.
Die gemäß der Erfindung zu verwendenden organischen Zinn- oder Bleiverbindungen weisen in diesem Sinne besonders günstige Eigenschaften auf. Einmal sind sie bereits vorgeschlagenen Verbindungen, wie z. B. Selenverbindungen, gegenüber mit Bezug auf die Herabsetzung der Entzündlichkeit des Wasserstoffs überlegen; außerdem aber sind sie leicht herstellbar, so daß sich ihrer allgemeinen Anwendung irgendwelche Hindernisse nicht entgegenstellen.The organic tin or lead compounds to be used according to the invention have in this sense particularly favorable properties. Once they are already proposed Connections such as B. selenium compounds, opposite with respect to the reduction superior to the flammability of hydrogen; in addition, however, they are easy to manufacture, so that their general Application do not oppose any obstacles.
Die Dichte des Wasserstoffs, der gemäß der Erfindung mit einem Mittel zur Verminderung der Explosionsgefahr versehen ist, ist nicht wesentlich erhöht. Er kann zum Füllen von Ballons und Luftschiffen verwendet werden, ohne daß die geringe Menge der Beimischungen das Auftriebsvermögen des Wasserstoffs vermindert. Die Explosionsgefahr des Wasserstoffs wird durch die Schmälerung des Entzundlichkeitsbereich.es stark verringert, und der zur Explosion erforderliche Kraftaufwand wird bedeutend erhöht. The density of the hydrogen, according to the invention with an agent for reducing the risk of explosion is not significantly increased. He can be used to fill can be used by balloons and airships without the small amount of admixtures the buoyancy of hydrogen is reduced. The risk of explosion of the hydrogen is increased by the Narrowing of the flammability range. It is greatly reduced, and that required for explosion The effort required is significantly increased.
Der gemäß dem Erfindungsverfahren behandelte Wasserstoff kann mit größerer Sicherheit in allen technischen Betrieben- zur Ölhärtung, Ammoniaksynthese usw. verwendet werden.The hydrogen treated according to the process of the invention can with greater Safety in all technical operations - used for oil hardening, ammonia synthesis, etc. will.
Man kann zur Verringerung der Gefahr auch noch passive Gase, wie Stickstoff, Kohlensäure oder Helium, zu dem Gemisch beifügen. To reduce the risk, passive gases such as nitrogen or carbonic acid can also be used or helium, to the mixture.
