Description
Verfahren zur Herstellung von Zelluloseestermassen. Es wurde gefunden, daß sich der Zyklohexanolester der Phthalsäure bzw. die Ester substituierter Phthalsäuren in ganz hervorragender Weise zur Zusammenverarbeitung mit Zelluloseestern eignen. Diese Phthalsäureester des Zyklohexanols sind ausgezeichnete Weichmachungsmittel für Zelulloseester. Man . kann Zelluloseester zusammen mit Phthalsäureestern des Zyklohexanols mit oder ohne Verwendung irgendeines anderen Lösungsmittels auf Lacke, Filme oder sonstige plastische Massen verarbeiten, die sich durch besondere Geschmeidigkeit und Biegsamkeit auszeichnen. Die Phthalsäureester des Zyklohexanols lassen sich auch besonders gut mit Kampfer bzw. anderen Kampferersatzmitteln verarbeiten.Process for the production of cellulose ester masses. It was found, that the cyclohexanol ester of phthalic acid or the esters of substituted phthalic acids perfectly suitable for processing with cellulose esters. These phthalic acid esters of cyclohexanol are excellent plasticizers for cellulose esters. Man. can cellulose esters together with phthalic acid esters des Cyclohexanol with or without the use of any other solvent on paints, Process films or other plastic masses that are particularly flexible and flexibility. The phthalic acid esters of cyclohexanol can also work particularly well with camphor or other camphor substitutes.
Die Verwendung von Phthalsäureestern niederer aliphatischer Alkohole zur Herstellung von Filmen ist bereits bekannt, doch haben sich diese Verbindungen als wenig brauchbar erwiesen. Bei längerem Lagern der damit hergestellten Filme werden diese leicht spröde und brüchig, ein Nachteil, der durch die Verwendung der Phthalsäurezyklohexanolester ausgeschaltet ist.The use of phthalic acid esters of lower aliphatic alcohols for making films is already known, but these compounds have become proved to be of little use. If the films made with them are stored for a long time these become easily brittle and fragile, a disadvantage caused by the use of the Phthalic acid cyclohexanol ester is switched off.
Ferner ist in der Patentschrift 251351 die Verwendung niederer Fettsäureester des Zyklohexanols als Ersatz für Amylazetat, also als ein nicht im Film bleibendes Lösungsmittel beschrieben. Die Verwendung des Phthalsäureesters des Zyklohexanols erfolgt also nach vorliegeildem Verfahren nicht in gleichem Sinne als leicht verdunstendes Lösungsmittel, eine Verwendung, die auch hei -den tekanntlich sehr hochsiedenden nicht flüchtigen Verbindungen ausgeschlossen wäre, sondern als im Film verbleibender, dem Film überraschenderweise eine besondere Geschmeidigkeit und Biegsamkeit verleihender Zusatz.Furthermore, in the patent specification 251351, the use of lower fatty acid esters is of cyclohexanol as a substitute for amyl acetate, i.e. as something that does not remain in the film Solvent described. The use of the phthalic acid ester of cyclohexanol so does not occur according to the present process in the same sense as easily evaporating Solvents, a use that is also known as very high-boiling volatile compounds would not be excluded, but as remaining in the film, Surprisingly, it gives the film a special suppleness and flexibility Additive.
Beispiel: 1 oo g Nitrozellulose werden mit 30 g Zyklohexanolphthalsäureester in entsprechender Menge Azeton gelöst und zu einer plastischen Masse verarbeitet.Example: 1 oo g of nitrocellulose are dissolved with 30 g of cyclohexanolphthalic acid ester in the appropriate amount of acetone and processed into a plastic mass.
