Description

Verfahren zur Herstellung von Kondensationsprodukten Es wurde gefunden, daß man wertvolle Kondensationsprodukte erhält, wenn man Melamin mit Formaldehyd und mit bei der Butandiol-i,3-Fabrikation als Nebenprodukte entstehendem Hexantriol oder bzw. und Octantetrol kondensiert.Process for the production of condensation products It has been found that valuable condensation products are obtained when melamine with formaldehyde is used and with hexanetriol formed as by-products in the butanediol-1,3 production or or and octantetrol condensed.

Die so erhaltenen neuen Produkte sind wasserlöslich und besonders geeignet zur Verwendung bei den mannigfachsten Textilveredelungsverfahren. So verbessern sie die Naß- und Haftfestigkeit der Filme aus Kunststoffdispersionen; sie ermöglichen also die Herstellung naßfesterGewebedublierungen.The new products thus obtained are water soluble and special suitable for use in the most diverse textile finishing processes. So improve the wet and adhesive strength of the films made from plastic dispersions; they allow i.e. the production of wet-strength fabric doublings.

Die vorliegenden Produkte übertreffen in ihrer Wirkung die entsprechenden unter Verwendung von Äthylenglykol hergestellten Kondensationsprodukte (vgl. Patentschrift 647 3(03). Da die nach vorliegendem Verfahren zur Verwendung kommenden Polyalkohole Hexantriol und Octantetrol bei der fürdieBunafabrikationbekanntlich in allergrüß'tem Maßstabe erfolgenden Herstellung von Butandiol-i,3 zwangsläufig als Nebenprodukte anfallen, wird durch Idas Auffinden einer vorteilhaften Verwendung für dieselben gemäß vorliegendem Verfahren ein großer technischer Effekt erzielt.The present products outperform the corresponding ones condensation products produced using ethylene glycol (cf. patent specification 647 3 (03). Since the polyalcohols used according to the present process Greetings from hexanetriol and octantetrol, as is well known for the bunafabrication Scale production of butanediol-i, 3 inevitably as by-products will arise by Idas finding an advantageous use for them achieved a great technical effect according to the present process.

Beispiel i Aus einer Mischung von i,89 Teilen Melamin, ior2 Teilen einer 37°/oigen Formaldehydlösung, die mit Sodal-ö@sung auf den pH-Wert 8 bis 9 eingestellt ist, 54o Teilen Hexantriol, 1,2, Teilen Magnesiumcarbonat und 6o, Teilen Toluol werden azeotropisch 555 Teile Wasser abdestilliert, wobei darauf zu achten ist, daß das Gemisch immer schwach alkalisch bleibt; nötigenfalls wird noch etwas Sodal6sung zugegeben. Die Endtemperatur beträgt etwa i i00. D'em fertigen Produkt werden 5 Teile Kieselgur zugesetzt, dann wird heiß abgesaugt. Man erhält i ioa Teile einer leicht gelblichen, nach Erkalten sehr viskosen Flüssigkeit, die mit Wasser in jeder Menge mischbar ist.Example i From a mixture of 1.89 parts of melamine, ior2 parts a 37% formaldehyde solution, which with sodal solution to a pH value of 8 to 9 is set, 54o parts of hexanetriol, 1.2 parts of magnesium carbonate and 6o parts of toluene are azeotropically 555 parts of water are distilled off, and then care must be taken that the mixture always remains slightly alkaline; if necessary, will some more soda solution added. The final temperature is about i 100. D'em finished 5 parts of kieselguhr are added to the product, then it is suctioned off while hot. You get i ioa parts of a slightly yellowish liquid, very viscous after cooling, which is miscible with water in any amount.

Beispiel: Ersetzt man in Beispiel i das Hexantriol durch die gleiche Menge Octantetrol und verfährt sonst wie in .Beispiel i angegeben, so erhält man etwa i icoo Teile einer etwas bräunlichen Flüssigkeit; die kalt ebenfalls sehr viskos ist. Sie 1-öst sich leicht in jeder Menge Wasser. .Example: If you replace the hexanetriol in example i with the same one Amount of Octantetrol and otherwise proceed as indicated in Example i, one obtains about i icoo parts of a somewhat brownish liquid; the cold ones are also very viscous is. They 1-eaten easily in any amount of water. .
