Description

Verfahren zur Herstellung hochkonzentrierter, höchst disperser, wäßriger kolloider Schwefellösungen. Es sind verschiedene Vorschläge zur Herstellung von kolloidem Schwefel gemacht worden, nach denen wäßrige Schwefelsole von nicht allzu hohen Konzentrationen und mehr oder weniger hoher Dispersität hergestellt werden können. Die Teilchengröße aller dieser Lösungen läßt sich im Ultramikroskop leicht genau feststellen. Ihre Herstellung ist z. B. die folgende: In Wasser wird in bekannter Weise unter Zufügung eines der üblichen Schutzkolloide Schwefeldioxyd und Schwefelwasserstoff gleichzeitig eingeleitet. Es entsteht alsdann eine kolloide Schwefellösung mit höchstens ro bis i2 Prozent Schwefel und einer Teilchengröße nicht unter go #t#x. Um nun die Wirkungen des Schwefels einerseits möglichst zu erhöhen und anderseits auch möglichst konzentrierte Lösungen herstellen zu können, ist es notwendig, eine recht geringe und gleichmäßige Teilchengröße zu erzielen. Man kann nämlich äußerst fein disperse Lösungen, deren Teilchen vollständig amikroskopisch sind, in Konzentrationen bis 5o- Prozent und mehr herstellen, da es sich gezeigt hat, daß Konzentration und Teilchengröße stark von der in der Reaktionsflüssigkeit herrschenden Temperatur abhängig sind. Die Teilchengröße nimmt mit fallender Temperatur stark ab, und in dem Maße, wie sie abnimmt, gelingt es, die Konzentration an Schwefel zu erhöhen. Arbeitet man bei Temperaturen von - 3 ° bis + q. °, so erhält man Sole mit einer unter 25 Mix liegenden Teilchengröße. Zweckmäßig ist es hierbei mit einem Überschuß von Schwefelwasserstoff zu arbeiten, da die Ausbeute an kolloidem Schwefel mit zunehmender Schwefelwasserstoffkonzentration zunimmt, während gleichzeitig die Menge der sich bei der Umsetzung auch bildenden Polythionsäuren ebenso stark abnimmt. Man kann auf diesem Wege höchst disperse Schwefellösungen mit 5o Prozent Schwefel herstellen.Process for the production of highly concentrated, highly dispersed, aqueous colloidal sulfur solutions. There are several proposals for making colloidal sulfur has been made, according to which aqueous brine of not too much high concentrations and more or less high dispersity can be produced can. The particle size of all of these solutions can easily be determined under the ultramicroscope determine exactly. Their production is z. B. the following: In water is known in Way with the addition of one of the usual protective colloids sulfur dioxide and hydrogen sulfide initiated simultaneously. A colloidal sulfur solution then arises with at most ro to i2 percent sulfur and a particle size not below go # t # x. To now the To increase the effects of sulfur on the one hand as much as possible and on the other hand as possible In order to be able to produce concentrated solutions, it is necessary to have a very small one and to achieve uniform particle size. You can disperse extremely finely Solutions, the particles of which are completely amicroscopic, in concentrations up to Produce 50 percent and more, as it has been shown that concentration and particle size are strongly dependent on the temperature prevailing in the reaction liquid. The particle size decreases sharply with decreasing temperature, and to the extent that if it decreases, it is possible to increase the concentration of sulfur. One works at temperatures from - 3 ° to + q. °, you get brine with a mix below 25 lying particle size. It is useful here with an excess of hydrogen sulfide to work, since the yield of colloidal sulfur increases with increasing hydrogen sulfide concentration increases, while at the same time the amount that is also formed in the implementation Polythionic acids also decrease sharply. In this way, highly dispersed sulfur solutions can be obtained make with 5o percent sulfur.

Nach einem bekannten Verfahren von D e bu st (Annal. 244, S. 80) werden zwar Schwefeldioxyd und Schwefelwasserstoff bereits bei Temperaturen einige Grade über o zur Einwirkung aufeinander ' gebracht. Bei den dort angegebenen Reaktionsbedingungen ist aber der Reaktionsverlauf ein so träger, daß eine'technische Auswertung dieses Verfahrens nicht in Frage kommt.According to a known method from Debus (Annal. 244, p. 80) it is true that sulfur dioxide and hydrogen sulphide already exist at temperatures a few degrees brought to influence one another through o '. Under the reaction conditions specified there but the course of the reaction is so sluggish that a technical evaluation of this Procedure is out of the question.
