Die bekannte Eigenschaft des Acetylentetrachlorids y während der Aufbewahrung, zumal bei Zutritt von Licht und Feuchtigkeit, Chlorwasserstoff abzuspalten, beschränkte die Verwendbarkeit dieser Flüssigkeit als Lösungsmittel für Harze, Lacke und andere organische Produkte in hohem Maße, da in sehr vielen Fällen, wie z. B. bei der Lackfabrikation, ein Chlorwasserstoffgehalt schäd-Hch wirkt. Die sich hieraus ergebenden Ubelstände lassen sich durch Verwendung eines kurz vor der Benutzung mittels Alkalien entsäuerten Acetylentetrachlorids nicht beseitigen, denn auch in den fertigen Lösungen scheidet das Lösungsmittel Chlorwasserstoff ab, was zu unerwünschten Nebenerscheinungen Veranlassung gibt.The well-known property of acetylene tetrachloride y during storage, especially when exposed to light and moisture, to split off hydrogen chloride, limited the use of this liquid as a solvent for resins, paints and other organic products to a great extent, since in many cases, such as. B. in paint production, a hydrogen chloride content has a damaging effect. The resulting problems cannot be eliminated by using acetylene tetrachloride which has been deacidified by means of alkalis shortly before use, because the solvent separates hydrogen chloride even in the finished solutions, which gives rise to undesirable side effects.
Das Entstehen von freiem Chlorwasserstoff im Acetylentetrachlorid wird gemäß vorliegender Erfindung dadurch verhindert, daß man Körper zusetzt, welche Chlorwasserstoff aufzunehmen imstande sind, und zwar organische Verbindungen, welche zwischen benachbarten Kohlenstoffatomen mindestens eine mehrfache Bindung besitzen und hierdurch zu Additionsreaktionen befähigt sind. Von diesen ist besonders das Terpentinöl bezw. das darin enthaltene Pinen vorteilhaft geeignet. Es zeichnet sich auch dadurch aus, daß die Chlorwasserstoffverbindungen etwa in gleichem Maße flüchtig sind wie Acetylentetrachlorid, was bei der Verwendung zum Umkristallisieren organischer Substanzen von Wichtigkeit ist. Durch Anwendung vorliegenden Verfahrens läßt sich das Acetylentetrachlorid längere Zeit aufbewahren und ist daher zum allgemeinen Gebrauch als Handelsartikel gut geeignet.The formation of free hydrogen chloride in the acetylene tetrachloride becomes more apparent in accordance with the present The invention prevents the addition of bodies which are able to absorb hydrogen chloride, namely organic ones Compounds which have at least one multiple bond between adjacent carbon atoms and thereby are capable of addition reactions. Of these, turpentine or oil is particularly important. the pinene contained therein advantageously suitable. It is also characterized by the fact that the hydrogen chloride compounds are volatile to the same extent as acetylene tetrachloride, which is of importance when used to recrystallize organic substances. By application present The acetylenetetrachloride can be stored for a long time and is therefore for general use as a commercial article well suited.
