FARBWERKE vorm. MEISTER LUCIUS & BRÜNING in HÖCHST a. M. Verfahren zur Darstellung von Verbindungen ungesättigter Fettsäuren mit Ameisensäure.FARBWERKE vorm. MASTER LUCIUS & BRÜNING in HÖCHST a. M. Process for the preparation of compounds of unsaturated fatty acids with formic acid.
Zusatz zum Patente 226222 vom 14. Mai 1908.Addendum to patent 226222 of May 14, 1908.
Patentiert im Deutschen Reiche vom 14. Mai 1908 ab. Längste Dauer: 13. Mai 1923.Patented in the German Empire on May 14, 1908. Longest duration: May 13, 1923.
Es wurde gefunden, daß, wenn man die Aldehyd- oder Ketonverbindungen des Hauptpatents 226222 ersetzt durch die Ameisensäure, die bekanntlich in vieler Beziehung als Aldehyd wirkt, man ganz ähnliche Resultate erhält.It has been found that when one uses the aldehyde or ketone compounds of the main patent 226222 replaced by formic acid, which is known to act as an aldehyde in many respects, gives very similar results receives.
ι kg Ricinolsäure und 100 g Ameisensäure werden gut verrührt und längere Zeit stehen gelassen. Dazu laufen bei 15 bis 300 200 g konzentrierte Schwefelsäure. Das Gemisch rührt noch einige Stunden nach und wird dann durch Auswaschen mit heißer Glaubersalzlösung von Schwefelsäure befreit; das erhaltene Öl wird abgehoben.ι kg of ricinoleic acid and 100 g of formic acid are stirred well and left to stand for a long time. For this purpose run at 15 to 30 0 200 g of concentrated sulfuric acid. The mixture is stirred for a few more hours and is then freed from sulfuric acid by washing with hot Glauber's salt solution; the oil obtained is lifted off.
