Description

Verfahren zur Darstellung von Verbindungen des Thiodiglykols. Es wurde gefunden, daß bei der Behandlung von Thiodiglykol mit aliphatischen Al- dehyden mit oder ohne Verwendung von Kondensationsmitteln neue wertvolle Verbindungen hergestellt werden können, die sich von den Ausgangsmaterialien dadurch unterscheiden, daß sie aus ihren wäßrigen Lösungen ausgesalzen werden können. Sie sind beständig in der Kälte und sind mehrfacher technischer Verwendung zugänglich, so z. B. als Lösungs- bzw. Quellungs- oder Weichmachungsmittel für Celluloseester, Harze usw. Über die Konstitution dieser Verbindungen ist zur Zeit noch nichts zu sagen. Im allgemeinen spalten sie bei höherer Temperatur leicht Aldehyd ab. Durch die Abspaltung des Aldehyds unterscheiden die neuen Verbindungen sich grundsätzlich von den im Chern. Zentralblatt 1899 1. Seite gig/:2o beschriebenen durch Einwirkung von Aldehyden auf Glykole erhaltenen Acetalen, die unzersetzt flüchtig sind.Process for the preparation of compounds of thiodiglycol. It has been found that in the treatment of thiodiglycol with aliphatic Al dehyden with or without the use of condensing agents valuable new compounds can be prepared, which differ from the starting materials in that they can be salted out from their aqueous solutions. They are resistant in the cold and are accessible for multiple technical uses, such. B. as a solvent, swelling or softening agent for cellulose esters, resins, etc. Nothing can be said about the constitution of these compounds at the moment. In general, they split off aldehyde easily at higher temperatures. Because the aldehyde is split off, the new compounds differ fundamentally from those in the core. Zentralblatt 1899 1st page gig /: 2o described acetals obtained by the action of aldehydes on glycols, which are volatile without decomposition.

Als Kondensationsmittel wurden besonders wirksam konzentrierte Säuren gefunden.Concentrated acids became particularly effective as condensing agents found.

B e i s p i e 1 1.Eg p ie 1 1.

ioo Teile Thiodiglykol werden mit 2,5 Teilen Formaldehyd 4oprozentig vermischt. Dazüi gibt man bei 15' 25 Teile konzentrierte Schwefelsäure, läßt mehrere Stunden stehen und steigert dann die Temperatur bis auf 30'. Man läßt über IN, acht stehen und gibt das Reaktionsgemisch in die fünffache Menge ioprozentige Glaubersalzlösung, stumpft die Säure mit Soda ab und hebt das abgeschiedene Öl ab.100 parts of thiodiglycol are mixed with 2.5 parts of formaldehyde to a concentration of 4 percent. In addition, 25 parts of concentrated sulfuric acid are added at 15 ', the mixture is left to stand for several hours and the temperature is then increased to 30'. It is allowed to stand over IN, eight and the reaction mixture is poured into five times the amount of 10% Glauber's salt solution, the acid is blunted with soda and the separated oil is lifted off.

B eispiel 2'.Example 2 '.

ioo Teile Thiodiglykol werden mit 2o Teilen Acetaldehyd vermischt; es tritt unter Erwärmung Reaktion ein. Die entstandene Verbindung bildet eine Flüssigkeit, die beim E, rwärmen auf hohe Temperatur Aldehyd abspaltet und ist ein vorzügliches Lösungsmittel für Harze, Celluloseester u. dgl.100 parts of thiodiglycol are mixed with 20 parts of acetaldehyde; a reaction occurs with heating. The resulting connection forms a liquid, which splits off aldehyde when heated to a high temperature and is an excellent one Solvents for resins, cellulose esters and the like.

In ähnlicher Weise können als Aldehyde Aldol, Crotonaldehyd, Glyoxal usw. verwendet werden.Similarly, aldol, crotonaldehyde, glyoxal can be used as aldehydes etc. can be used.
