Verfahren zur Entfernung von Schwefelkohlenstoff aus Basen.
EMI1.1
grösste Teil aus Schwefelkohlenstoff. Die Verfahren zur Beseitigung dieser Verbindungen haben daher sämtlich die Entfernung des Schwefelkohlenstoffes zur Grundlage gehabt, haben aber bisher zu einem praktischen Ergebnis nicht geführt.
Ein bei gewöhnlicher Temperatur und noch bei sehr grosser Verdünnung des Schwefelkohlenstoffs wirkendes billiges Absorptionsmittel ist Alkalizellulose oder Alkalizellulose mit Kalk gemischt, wobei es zweckmässig ist, vorher in bekannter Weise für eine möglichst voll- kommene Entfernung von Kohlensäure und Schwefelwasserstoff Sorge zu tragen.
Zur Ausführung des Verfahrens wird Zellulose oder zellulosehaltiges Material, z. B. Sulfitzellulose und deren Abfälle, Sägespäne, Sägemehl, Lumpen, Baumwolle, Baumwollabfälle und dgl. in die Alkaliverbindung der Zellulose übergeführt, mit der sich der in Gasen befindliche Schwefelkohlenstoff zu Zellulosexanthogenat vereinigt, das entsprechend verwertet werden kann. Diese Gasroinigungsmasse ist durch ihre poröse Beschaffenheit besonders geeignet, um einerseits dem Gas den nötigen freien Durchgang zu schaffen und andererseits dem Schwefelkohlenstoff eine möglichst grosse Oberfläche zur Absorption darzubieten.
Das Gas wird so von Schwefelkohlenstoff befreit und gibt, wenn noch die sonst üblicho Reinigung von Schwefelwasserstoff vorgenommen ist, beim Verbrennen fast keine
EMI1.2
spezifische Gewicht verringert, wodurch das Gas auch zum Füllen von Luftballons geeigneter wird.
Kino regelmässige Überwachung des Reinheitsgrades ist beispielsweise möglich durch die prachtvolle, in ruhinroten Prismen kristallisierende Verbindung des Schwefelkohlenstoffs in Triäthylphosphin.

Process for removing carbon disulfide from bases.
EMI1.1
mostly made of carbon disulfide. The methods for eliminating these compounds have therefore all been based on the removal of carbon disulfide, but have so far not led to a practical result.
A cheap absorbent that works at normal temperature and even when the carbon disulfide is very diluted is alkali cellulose or alkali cellulose mixed with lime, whereby it is advisable to ensure that carbonic acid and hydrogen sulfide are removed as completely as possible beforehand in a known manner.
To carry out the method, cellulose or cellulosic material, e.g. B. Sulphite cellulose and its waste, sawdust, sawdust, rags, cotton, cotton waste and the like. Converted into the alkali compound of cellulose, with which the carbon disulfide in gases combines to form cellulose xanthate, which can be recycled accordingly. Due to its porous nature, this gas cleaning compound is particularly suitable for creating the necessary free passage for the gas on the one hand and offering the carbon disulfide the largest possible surface for absorption on the other.
The gas is freed from carbon disulfide and, if the otherwise usual purification of hydrogen sulfide has been carried out, gives almost none when burned
EMI1.2
The specific weight is reduced, which makes the gas more suitable for filling balloons.
Cinema regular monitoring of the degree of purity is possible, for example, through the magnificent compound of carbon disulfide in triethylphosphine, which crystallizes in ruby-red prisms.
