Description
Verfahren zur Herstellung von Zellstoff Zur Herstellung von Cellulose aus Pflanzenfaserstoffen, wie Holz, Stroh, Lumpen, Papierabfällen usw., wird das Ausgangsmaterial mit Aufschlußlösungen, wie Natron-oder Sulfitlauge, bearbeitet, welche nicht zerstörend auf den Zellstoff wirken dürfen, welche aber die Nichtcellulosebestandteile teils lösen, teils zersetzen. Zu dem gleichen Zwecke wurden auch bereits Phenole und deren Abkömmlinge .in freiem Zustande in Anwesenheit von Säuren oder Chlor oder als Salze in Gegenwart alkalischer Lauge benutzt.Process for the production of cellulose For the production of cellulose from plant fibers such as wood, straw, rags, paper waste, etc., this becomes Raw material processed with digestion solutions, such as sodium or sulphite liquor, which must not have a destructive effect on the cellulose, but which the non-cellulose components partly dissolve, partly decompose. Phenols have also been used for the same purpose and their derivatives .in the free state in the presence of acids or chlorine or used as salts in the presence of alkaline lye.
Vorliegende Erfindung betrifft eine Verbesserung ges längst bekannten :Natronverfahrens der Celluloseherstellung, welches darin besteht, daß zur wässerigen Natronlauge, mit welcher das cellulosehaltige Material bearbeitet wird, außer einer sehr kleinen Menge (nicht mehr als einige zehntel Prozent) Phenol auch noch geringe Mengen von einigen hochmolekularen, organischen lZ-onosulfonsäuren zugesetzt werden. Unter den Phenolen eignen sich außer dem gewöhnlichen Phenol auch Kresole, Yylenole und Naphthole. Die Bedingungen ihrerAnwendung im vorliegenden Fall unterscheiden sich von den früher bekannten dadurch, daß man sie in sehr ,kleinen Mengen und unbedingt in Anwesenheit alkalischer Salze der Sulfonsäuren anwendet.The present invention relates to an improvement on well known : Soda process of cellulose production, which consists in that for aqueous Caustic soda, with which the cellulose-containing material is processed, except for one very small amount (no more than a few tenths of a percent) phenol also small Quantities of some high molecular weight, organic lZ-onosulfonic acids can be added. Among the phenols, in addition to the usual phenol, cresols and yylenols are also suitable and naphthols. The conditions of their application in the present case differ differs from the previously known ones in that they are used in very, small quantities and unconditionally applies in the presence of alkaline salts of sulfonic acids.
Unter den organischen Sulfonsäuren eignen sich zu diesem Zwecke nur hochmolekulare Monosulfonsäuren, z. B. Naphthastilfonsäure, welche man durch Sulfurieren der Naphthadestillate oder des Braunkohlenteers gewinnt, oder sogenannte aromatische Sulfofettsäuren, welche durch Einwirkung von Schwefelsäure auf eine Mischung ungesättigter Fettsäure mit aromatischen Kohlenwassers.toffen erhalten werden, oder endlich die sich .durch Sulfurieren des hydrogenisierten Anthracens bildende Oktohydroanthracensulfonsäure.Among the organic sulfonic acids are only suitable for this purpose high molecular weight monosulfonic acids, e.g. B. Naphthastilfonsäure, which one by sulfurizing the naphtha distillate or the lignite tar wins, or so-called aromatic Sulphofatty acids, which by the action of sulfuric acid on a mixture of unsaturated Fatty acids with aromatic hydrocarbons, or finally the Octohydroanthracene sulfonic acid formed by sulfurizing the hydrogenated anthracene.
Die Anwesenheit in der alkalischen Lösung dieser Säuren bzw. deren Alkalisalze reduziert stark die Oberflächenspannung der Lösung, erhöht ihre benetzenden und lösenden Eigenschaften und fördert das Durchtränken des faserigen, porös:eri Rohmaterials mit alkalischer Lösung. Somit wirkt in Anwesenheit .der Salze solcher Sulfosäuren die Lösung rascher und regelmäßiger auf .die Nichtcellulosebestandteile des Ausgangsmaterials ein, und man bekommt eine reinere und vollkommenere Cellulose, als wenn die alkalische Lösung ohne Beimischung dieser Stoffe angewandt wird.The presence in the alkaline solution of these acids or their Alkali salts greatly reduce the surface tension of the solution, increasing its wetting and dissolving properties and promotes soaking of the fibrous, porous: eri Raw material with alkaline solution. Thus, such acts in the presence of the salts Sulphonic acids the solution faster and more regularly on. The non-cellulose components of the starting material, and you get a purer and more perfect cellulose, than when the alkaline solution is used without the addition of these substances.
Es wurde auch festgestellt, daß man durch den Zusatz von Sulfosäuren und Phenolen zur alkalischen Lösung bei der Bearbeitung z. B. von Holz oder Stroh nicht nur ein vollständigeres Abscheiden der Nichtcellulos,ebestandteile erreicht, sondern es wird auch gleichzeitig gas Bleichen mit Chlor oder Chlorkalk beschleunigt; es werden weniger Reagentien verausgabt, und die Farbe der zu erhaltenden Cellulose verbessert sich. Sowohl .die Phenole als auch die Sulfonsäuren werden der alkalischen Lösung in kleinen Mengen zugesetzt, -so @daß sie nur einen sehr kleinen Teil der sich in der Lösung befindlichen Lauge neutralisieren.It has also been found that the addition of sulfonic acids and phenols to the alkaline solution when processing z. B. of wood or straw not only achieves a more complete separation of the non-cellulosic constituents, but also accelerates gas bleaching with chlorine or chlorinated lime at the same time; fewer reagents are expended and the color of the cellulose to be obtained improves. Both the phenols and the sulfonic acids are added to the alkaline solution in small amounts - so that they only neutralize a very small part of the lye in the solution.
Beispiel In einem rotierenden Kessel werden gelagert: 16o Gewichtsteile Stroh, 26o Gcwichtsteile Natronlauge in I2° Bd, 0,2,5 Gewichtsteile Naphthasulfosäuren, welche aus Naphthadestillaten, spez. Gew. o,86o, erhalten werden, 0,25 Gewichtsteile rohen Kresols, welches nicht weniger als go°/o Kresole enthält. Die Mischung wird unter Druck von 4,5 Atm. im Laufe von q. Stunden erwärmt und weiterhin ebenso bearbeitet wie heim Natronverfahren.Example The following are stored in a rotating kettle: 16o parts by weight of straw, 26o parts by weight of sodium hydroxide solution in 12 ° Bd, 0.2.5 parts by weight of naphthasulfonic acids, which are obtained from naphtha distillates, spec. 0.86 by weight, 0.25 part by weight of crude cresol containing not less than 10,000 cresols. The mixture is under pressure of 4.5 atm. in the course of q. Hours heated and still processed in the same way as with the baking soda method.
