KAISERLICHESIMPERIAL
PATENTAMTPATENT OFFICE
Natürliches oder künstliches schwefelsaures Strontium wird durch Glühen mit Kohle oder organischen Stoffen in bekannter Weise reducirt. Nach dem Erkalten wird durch systematisches Auslaugen in geschlossenen Gefäfsen eine Lösung von Schwefelstrontium erhalten. Mit derselben werden die zur Gewinnung von Papierfaser geeigneten Rohstoffe (Stroh,. Pflanzenfaser und namentlich Holz), nach vorangegangener Zerkleinerung in eisernen Gefäfsen bei einer Temperatur, welche einer Dampfspannung von 6 bis 10 Atmosphären entspricht, 6 bis 8 Stunden lang erhitzt. Die dadurch aufgeschlossene und von den inkrustirenden Stoffen befreite Faser wird auf mechanischem Wege durch Siebböden und durch systematisches Auswaschen mit Wasser von der Lauge getrennt, darauf wie Papierzeug in Holländern zerschlagen, gewaschen und auf der Papiermaschine verarbeitet.Strontium, natural or artificial, is made by glowing with coal or organic substances are reduced in a known manner. After cooling down, systematic Leaching in closed vessels to obtain a solution of sulfur strontium. With the same the raw materials suitable for the production of paper fiber (straw, vegetable fiber and especially wood), after previous crushing in iron vessels at a temperature which corresponds to a vapor tension of 6 to 10 atmospheres, 6 to 8 hours heated for a long time. The fiber opened up and freed from the incrusting substances is mechanically through sieve trays and by systematic washing out with water separated from the lye, then smashed like paper stuff in Dutch, washed and opened processed by the paper machine.
Durch die hierbei erhaltene Lösung wird in geschlossenen Gefäfsen unter Erwärmung Kohlensäure geleitet .und der entweichende Schwefelwasserstoff in bekannter Weise entweder weiter verarbeitet oder unschädlich gemacht. Durch Einwirkung der Kohlensäure scheidet sich aus der Lauge ein Gemenge von kohlensaurem Strontium und organischen Verbindungen ab, das filtrirt und getrocknet wird. Bei starkem Glühen in reducirender Flamme verwandelt sich diese Masse in Aetzstrontium, aus dem durch weitere Behandlung mit Wasser das reine Hydrat gewonnen wird.The solution obtained in this way causes carbonic acid to be generated in closed vessels while being heated and the escaping hydrogen sulfide either on in a known manner processed or rendered harmless. Due to the effect of carbonic acid, it is precipitated the lye removes a mixture of carbonic acid strontium and organic compounds, which is filtered and dried. With a strong glow in a reducing flame it transforms this mass in Aetzstrontium, from which by further treatment with water the pure hydrate is won.
