Description

Herstellung von Preßlingen aus Alkalipyrosulfiten. Die Herstellung von Preßlingen aus Alkalipyrosulfiten, wie sie beispielsweise in der Weinbereitung angewendet «-erden, begegnet großen Schwierigkeiten wegen der durch zugesetzte Fremdstoffe bewirkten leichten Zersetzlichkeit der Metabisulfite.Manufacture of pellets from alkali pyrosulfites. The production of pellets made of alkali pyrosulfites, such as those used in winemaking applied «-erden, encounters great difficulties because of the added foreign matter caused the metabisulfites to decompose easily.

Es wurde nun gefunden, daß man haltbare, feste Preßlinge beliebiger Form aus Pyrosulfiten herstellen kann, wenn man trockenes Kalium- oder '."Tatriumpyrosulfit mit einer kleinen Menge zweckmäßig gesättigter Alkalikarbonatlösung zu einer formbaren Masse verreibt und diese Masse in beliebiger Form preßt. Die geformten Preßlinge werden dann bei So bis 6o° getrocknet. Die auf diese Weise hergestellten Preßlinge besitzen hohe Druckfestigkeit, sind leicht und klar in Wasser löslich und weisen bei Abschluß von Feuchtigkeit große Beständigkeit auf. Ihr Gehalt an Schwefel ist nahezu der gleiche wie bei losem Pvrosulfit.It has now been found that durable, solid compacts of any desired Form can be made from pyrosulfites if you dry potassium or '. "Tatriumpyrosulfit with a small amount of suitably saturated alkali carbonate solution to form a moldable one Rub mass and press this mass in any shape. The molded pellets are then dried at Sun to 60 °. The compacts produced in this way have high compressive strength, are easily and clearly soluble in water and are white in the absence of moisture, great resistance. Your sulfur content is almost the same as for loose pvrosulfite.
