Claims (1)

Patent-Anspruch:Patent claim: Verfahren zum Ausfällen von in Alkohol gelöster Nitrozellulose, dadurch gekennzeichnet, daß man den siedenden Alkohol mit Wasser verdünnt und aus der heißen Lösung die Nitrozellulose durch Zusatz eines Elektrolyten ausflockt und alsdann durch nochmaliges Kochen den sich bildenden Niederschlag zum Zusammenballen und Absetzen am Boden des, Gefäßes bringt.Process for precipitating nitrocellulose dissolved in alcohol, characterized in that the boiling alcohol is diluted with water and the nitrocellulose is flocculated from the hot solution by adding an electrolyte and then by boiling again the precipitate that forms to agglomerate and settle at the bottom of the vessel brings.
