Description

Lösungsmittel für Acetylen Die Erfindung betrifft die Verwendung von Thiophan-i-oxyd (Tetramethylensulfoxyd) als Lösungsmittel für Acetylen.Solvent for acetylene The invention relates to the use of Thiophane-i-oxide (tetramethylene sulfoxide) as a solvent for acetylene.

Es sind bereits die verschiedensten organischen Lösungsmittel, z. B. Betone, Ester, Äther, Lactone und Carbonsäureamide, zum Lösen von Acetylen bekannt. Das Lösevermögen dieser Stoffe ist recht unterschiedlich. In der Praxis hat sich bisher vor allem Aceton bewährt, obwohl sein niedriger Siedepunkt nachteilig für seine Verwendung ist und das Aufnahmevermögen für Acetylen im Vergleich zu anderen Lösungsmitteln, z. D. N-Alkylpyrrolidonen, geringer ist. Verglichen mit 1\T-Alkylpyrrolidonen ist Thiophan-i-oxvd leichter zugänglich und, wie auch verglichen mit Aceton, bei chemischen Umsetzungen weniger unerwünschten Nebenreaktionen ausgesetzt.There are already a variety of organic solvents such. B. concretes, esters, ethers, lactones and carboxamides, known for dissolving acetylene. The dissolving power of these substances is quite different. In practice it has So far, especially acetone has proven its worth, although its low boiling point is disadvantageous for its use is and its capacity for acetylene compared to others Solvents, e.g. D. N-alkyl pyrrolidones, is lower. Compared to 1 \ T-alkylpyrrolidones Thiophan-i-oxvd is more accessible and, as compared to acetone, at chemical reactions are less exposed to undesired side reactions.

Weiterhin sind Alkyl-amidophosphate zum Lösen von Acetylen bekannt. Auch hat man für den gleichen Zweck bereits Dimethylsulfoxyd verwendet. Nachteilig für eine praktische Verwendung des Dimethylsulfoxyds ist dabei der Umstand, daB es bei -f- 8° schmilzt und thermisch nicht stabil ist.Furthermore, alkyl amidophosphates for dissolving acetylene are known. Dimethyl sulfoxide has also been used for the same purpose. Disadvantageous for a practical use of dimethyl sulfoxide is the fact that it melts at -f- 8 ° and is not thermally stable.

Den bekannten Lösungsmitteln gegenüber besitzt Thiophan-i-oxyd ein ausgezeichnetes Lösungsvermögen für Acetylen.Compared to the known solvents, thiophane-i-oxide has a excellent solvency for acetylene.

So löst beispielsweise das Thiophan- i -oxyd bei 2d°' und- Normaldruck das 31fache seines Vo- Lumens an Acetylen. Es kann daher ausgezeichnet zur Aufbewahrung von Acetylen in Druckflaschen und zum Auswaschen von Acetylen aus verdünnten Gasen, wie man sie beisielsweise bei der thermischen oder elektrischen' Zersetzung von niedermolekularen aliphatischen Kohlenwasserstoffen oder bei der unvollständigen Verbrennung derartiger Kohlenwasserstoffe mit Sauerstoff erhält, verwendet werden. Ein besonderer Vorteil ist sein hoher Siedepunkt (238°). Es ist mischbar mit Wasser und aromatischen Kohlenwasserstoffen, z. B. Benzol. Toluol und deren Abkömmlingen. Da das Thiophan-i-oxy d verhältnismäßig reaktionsträge und thermisch sehr stabil ist, kann man seine Lösungen mit Acetylen für die Umsetzungen von Acetylen mit anderen Stoffen verwenden.For example, the thiophane oxide dissolves at 2d ° and normal pressure 31 times his voucher Lumen of acetylene. It can therefore be excellent for storing acetylene in pressure bottles and for washing out acetylene diluted gases, such as those used in thermal or electrical ' Decomposition of low molecular weight aliphatic hydrocarbons or in the incomplete combustion of such hydrocarbons with oxygen, be used. A particular advantage is its high boiling point (238 °). It is miscible with water and aromatic hydrocarbons, e.g. B. benzene. Toluene and their descendants. Since the thiophane-i-oxy d is relatively inert and thermally is very stable, you can use its solutions with acetylene for the reactions of acetylene use with other substances.
