Description
Verfahren zur Herstellung von Alkoxy- bzw. Aroxy- oder Alkylalkoxyborinen
Es wurde gefunden, daß Alkoxy- bzw. Aroxy- oder Alkylalkoxyborine ohne Verwendung
von Diboran hergestellt werden können, wenn Halogenborsäureester mit insbesondere
Alkali- oder Erdalkalihydriden oder deren Gemischen, gegebenenfalls unter Druck,
vorzugsweise in Gegenwart von Lösungs-, Verdünnungs- oder Suspensionsmitteln, umgesetzt
werden. Die Reaktionen verlaufen unter anderem nach folgender Gleichung
Im allgemeinen ist es zweckmäßig, die Suspension von obigen Hydriden zunächst mit einer geringen Menge, z. B. 0,1 bis 10 %, Borsäureester zu aktivieren und dann den Halogenborsäureester zuzugeben.In general, it is advantageous to use the suspension of the above hydrides initially with a small amount, e.g. B. 0.1 to 10% to activate boric acid ester and then add the haloboric acid ester.
Man erhält so Alkoxyborine in hohen Ausbeuten und großer Reinheit, die als Hydrierungsmittel in der anorganischen und organischen Chemie, als Treib-oder Brennstoffe bzw. als Zusatz zu Treib- und Brennstoffen, als Zwischenprodukt zur Herstellung verschiedener Borverbindungen, z. B. von Komplexborhydriden, als Polymerisation.skatalysatoren und ähnlichem verwendet werden.This gives alkoxyborines in high yields and great purity, as a hydrogenating agent in inorganic and organic chemistry, as a blowing agent or Fuels or as an additive to fuels and fuels, as an intermediate product for Production of various boron compounds, e.g. B. of complex borohydrides, as Polymerisation.skatalysatoren and the like can be used.
Beispiel Zu einer Suspension von: 12 g Na H in 250 ccm Mineralöl (Viscobilöl V 386) wurden bei 80° C zunächst etwa 4 ccm Borsäureäthylester gegeben und anschließend insgesamt 68 g Chlorborsäu:reester mit einem CI-Gehalt von 26 % zugetropft. Exotherme Reaktion unter Abdestillieren der gebildeten Alkoxyborine zwischen 91 und 105° C. Zum Schluß wurde bis auf 180° C erhitzt. Erhalten wurden 54,3 g chlorfreies Dialkoxybo@rin-Borsäureester-Gemisch.EXAMPLE To a suspension of: 12 g of Na H in 250 cc of mineral oil (Viscobilöl V 386), about 4 cc of ethyl borate were first added at 80 ° C. and then a total of 68 g of chloroboric acid ester with a CI content of 26% were added dropwise. Exothermic reaction with distilling off the alkoxyborines formed between 91 and 105.degree. C. Finally, the mixture was heated up to 180.degree. 54.3 g of chlorine-free dialkoxyboron-boric acid ester mixture were obtained.
