Description

Gelatinierungs- und WeichmachungsmÜttel.für,Cellulosederivate-In gewissen Estern von Glycerinäthern wurden Stoffe gefunden, die sich in besonders hohem Maße als Gelatinierungs- und Weichmachungsmittel für Celluloseester und -äther eignen und die zu diesem Zweck gebrauchten Glycerinester hinsichtlich gelatinierender Wirkung, Stabilität gegen Zersetzung und Verseifung sowie Lichtbeständigkeit erheblich übertreffen.Gelatinizing and plasticizing agent for cellulose derivatives in certain Esters of glycerine ethers have been found to have a particularly high degree of substances suitable as gelatinizing and plasticizing agents for cellulose esters and ethers and the glycerine esters used for this purpose in terms of gelatinizing effect, Significantly exceed stability against decomposition and saponification as well as light resistance.

Es handelt sich um solche Ester von Gly cerinäthern, bei denen Glycerin ein- oder mehrmals mit Glycerin veräthert ist und die Veresterung mit Essigsäure oder seinen homologen bis zur Valeriansäure einschließlich stattgefunden hat. Diese Verbindungen stellen hochviscose Flüsgigkeiten vor, die in Wasser unlöslich, geruchlos und farblos sind. Sie besitzen als verhältnismäßig hochmolekulare Körper einen=.hohen Siedepunkt und geringe-Flüchtigkeit.. Während bei, den als Lösungs- und Celätinierungsmittel für Cellulosederivate bekannten Estern von Glycolmonoäthyläthern eine Vergrößerung des Moleküls nur durch Veresterung mit insbesondere aromatischen Säuren erzielt wird, ist dies zum Vorteil für die gelatinierende Wirkung bei den gemäß vorliegender Erfindung zur Anwendung gelangenden Verbindungen durch eine Anhäufung gelatinierend wirkender Gruppen erreicht.These are those esters of glycerine ethers, in which glycerine is etherified one or more times with glycerine and esterification with acetic acid or its homologues up to and including valeric acid took place. These Compounds represent highly viscous liquids that are insoluble in water, odorless and are colorless. As a relatively high-molecular body, they have a = .high Boiling point and low volatility .. While with, as solvents and Celätinierungsmittel for cellulose derivatives known esters of glycol monoethyl ethers an enlargement of the molecule is only achieved by esterification with, in particular, aromatic acids this is to the advantage of the gelatinizing effect in the case of the present invention Invention applied compounds gelatinizing by an accumulation effective groups reached.

Beispiele i. ioo Teile acetonlösliche Acetylceliulose werden mit 3o bis So Teilen Diglycerintetraacetat der Formel in einem Gemisch von Aceton mit etwas Alkohol und Benzol - gelöst. Die filtrierte Lösung kann auf Lacke, Filme, Blöcke, Platten, Rohre und andere Kunstprodukte verarbeitet werden.Examples i. 100 parts of acetone-soluble acetyl cellulose are mixed with 30 to 50 parts of diglycerol tetraacetate of the formula in a mixture of acetone with a little alcohol and benzene - dissolved. The filtered solution can be used on paints, films, blocks, plates, pipes and other artifacts.

2. ioo Gewichtsteile Methylcellulose werden in einem aus 2q.0 Volumteilen Methylalkohol, 240 Volumteilen Benzol, 240 Volumteilen Toluol und 240 Volumteilen Äthylalkohol bestehenden Gemisch unter Zugabe von 5ö Gewichtsteilen Diglycerintetraacetat gelöst. Aus der filtrierten Lösung werden in üblicher Weise Folien, Lacke und andere Kunstprodukte hergestellt. Weitere Vertreter der als Gelatinierungs-und Weichmachungsmittel für Nitrocellulose, Acetylcellulose, andere und gemischte Ce1-luloseester sowie Celluloseäther in Betracht kommenden Ester von Glycerinäthern sind z. B. Diglycerintriacetat der Formei Triglycerintriacetat der Formel Triglycerintetraacetat der Formel Selbstverständlich können die zu gewinnenden Massen und Lacke gleichzeitig auch mehrere solcher Gelatinierungsmittel enthalten und auf dem Wege ihrer Darstellung mit allen den in dieser Industrie gebräuchlichen Zusatzstoffen, wie Farbstoffen, Füllmitteln u. dgl., versetzt und den sonst üblichen Verarbeitungsmethoden unterworfen werden.2. 100 parts by weight of methyl cellulose are dissolved in a mixture consisting of 2q.0 parts by volume of methyl alcohol, 240 parts by volume of benzene, 240 parts by volume of toluene and 240 parts by volume of ethyl alcohol with the addition of 50 parts by weight of diglycerol tetraacetate. Films, lacquers and other synthetic products are produced in the usual way from the filtered solution. Further representatives of the esters of glycerol ethers which are suitable as gelatinizing and softening agents for nitrocellulose, acetyl cellulose, other and mixed cellulose esters and cellulose ethers are z. B. Diglycerol triacetate of the formula Triglycerol triacetate of the formula Triglycerol tetraacetate of the formula Of course, the masses and varnishes to be obtained can also contain several such gelatinizing agents at the same time and can be mixed with all the additives commonly used in this industry, such as dyes, fillers and the like, and subjected to the usual processing methods.
