 alkoholischen Gärung, sondern auch zur Säuregärung ausnutzen. Auch kann das Material als Nährboden für Stickstoffbackterien dienen. Es kann ferner einer rein chemischen Aufarbeitung unterworfen werden, z. B. der Trockendestillation mit oder ohne Wasserdampf, der Alkalischmelze oder der Oxydation. 



   Wenn bei der SulfitzellstoffdarsteJlung eine möglichst hochprozentige Ausbeute an leicht, und gut ausnutzbaren Nebenprodukten entstehen soll, so ist es also vorteilhaft, den Ansatz

 direkt oder nach einem weiteren Aufschluss mit starker Lauge zur Erzeugung von Steinholz und ähnlichem Material, als   Füllsel   zur Papierfabrikation, zur Linoleumfabrikation. für Anstrichmasse usw. gebrauchen oder durch eine weitere Hydrolyse mit   konzentrierter oder verdünnter   Schwefelsäure auf Zucker verarbeiten.

 alcoholic fermentation, but also for acid fermentation. The material can also serve as a breeding ground for nitrogen bakeries. It can also be subjected to a purely chemical work-up, e.g. B. dry distillation with or without steam, alkali melt or oxidation.



   If the production of sulfite pulp is to produce as high a percentage as possible of by-products that can be easily and easily exploited, then it is advantageous to use the

 directly or after a further digestion with strong lye for the production of stone wood and similar material, as a filler for paper production, for linoleum production. Use for paints etc. or process by further hydrolysis with concentrated or dilute sulfuric acid for sugar.

Nebenprodukten bei der Sulfitzellstoffdarstellung der Ansatz chemisch und zeitlich in zwei Phaspu zerlegt wird, und zwar 1. in ein kurzes Dämpfungsverfahren mit Hilfe einer an SO2 und Erdalkali 0der Alkali armen Lauge und 2. in das darauffolgende Hauptaufschlussverfabrcu mit einer Lauge von üblichem Gehalte an SOg und Erdalkalien bzw. Alkalien. By-products in the preparation of sulphite pulp the approach is broken down chemically and temporally into two phases, namely 1. in a short steaming process with the help of a lye that is poor in SO2 and alkaline earth and 2. in the subsequent main digestion process with a lye with the usual contents of SOg and Alkaline earths or alkalis.
