Description

Verfahren zur Herstellung von Lösungen organischer Körper. F: wurde gefunden, daß die zyklischen Acetale, die All-zylidenäther von u- und P-Glvkolen, die durch Acetalisierung von r - z- oder t - 3-Glykolen mit Aldehyden, wie Formalde-hyd, Acetaldehyd, Crotonaldehyd u. a., leicht her:tellbar und vermöge ihrer zyklischen Natur stabiler sind als Acetal und seine Homologen, für sich oder in Mischung mit anderen Flüssigkeiten, insbesondere Alkoholen, hervorragende Lösungsmittel für die verschiedensten organischen Substanzen sind. Technische Bedeutung haben insbesondere der aus Glykol und Acetaldehy d erhältliche _#,tliylenäthvliclenäther vom Siedepunkt $o bis 82, der aus Butyraldehyd und Glykol entstehende Äthylenlititvliclenätlier vorn Sieclepunkt 13o° und das Acetal des i - 3 Buty-lenglykols vom Siedepunkt r8o°.Process for the preparation of solutions of organic bodies. Q: It was found that the cyclic acetals, the all-cylidene ethers of u- and P-glycols, which are produced by acetalization of r - z or t - 3 glycols with aldehydes such as formaldehyde , acetaldehyde, crotonaldehyde and others, easily producible and, because of their cyclic nature, are more stable than acetal and its homologues, on their own or in a mixture with other liquids, in particular alcohols, are excellent solvents for a wide variety of organic substances. Tliylenäthvliclenäther, obtainable from glycol and acetaldehyde, is of particular technical importance from the boiling point $ 0 to 82, the ethylenite ether formed from butyraldehyde and glycol at the front seal point 130 ° and the acetal of i-3 butylene glycol from the boiling point r8o °.

Diese Äther lösen vor allein Celluloseester, natürliche und künstliche Harze, Kunstschellack, Farbstoffe aller Art und sogar Kautschuk leicht auf und lassen sich daher praktisch zu den verschiedensten Zwecken vorzüglich in der Lack- und Firnisindtistrie anwenden.These ethers mainly dissolve cellulose esters, natural and artificial Resins, artificial shellac, dyes of all kinds and even rubber are easy to get on and off therefore practically for a wide variety of purposes excellent in the paint and Apply varnish industry.

Beispielsweise lösen die genannten zyklischen Acetale Nitro- und Benzvlcellulose im Verhältnis i :5, Kautschuk und Celluloid r : ro;.das Acetat aus Formaldehyd und T . 3-$utylenglvl@ol vom Siedepunkt 115 bis 120' löst auch Acetvlcellulose im Verhältnis i : io glatt auf.For example, the above-mentioned cyclic acetals dissolve nitro and benzyl cellulose in the ratio i : 5, rubber and celluloid r: ro; .the acetate from formaldehyde and T. 3- $ utylenglvl @ ol with a boiling point of 115 to 120 ° also dissolves acetylenic cellulose smoothly in the ratio i: io.
