Description

Verfahren zur Herstellung von Acetylencarbinolen Gege@nsta,nd: des- Patents 86aoo5 ist ein Verfahren zur Herstellung von, Propin-(i)-d methyl-(3, 3)-0l-(3) durch Anlagerung von Aceton an Acetylen in Gegenwart von :gepulveirt-em Ka,liumhyd,roxyd' und organischen: Das Verfahren # besteht darin, daß man als Lösungsmittel ein Acetal oder ein tertiäres Amin verwendet, dieses mit gepulvertem Kaliumhydroxyd und mit einem Teil des Acetylens versetzt, bei höchstens etwa, o° das Aceton und dann den Rest des Acetylens zufügt, die entstandene Kaliumverbindung des Carbinols mit Wasser zerlegt und wie!.üblich aufarbeitelt. Die Erfindung betrifft eine weitere Ausbildung des vorgenannten Verfahrens, wobei man an Stelle vonAcetonanderealiphatischeKetone oder cyclische Ketone, wie Cyclohe!xanon, oder aliphatische Aldehyd'.e, oder daß man statt Acetylen sein ie Mono,- sub,stitutionsprodukte verwendet. Die, Reaktion, kann bei etwa o°' erfolgen, sie- läßt sich aber auch bei tieferen Temperaturen ausführen. Bei.-spiel i Ma,n@ mischt 175 Teile gepulvertes Ka.lium- hyd:roxyd, mit 5oo Teilern Dimethylformal beii einer Temperatur von ertwa i5'0, läßt diel Temperatur bis auf etwa 3o bis 33° ,steigen, kühlt dass Gemisch auf etwa & ab, und leitet sodann., ungefähr 2o Teile Aceityleni ein. Darauf fügt man allmählich 45 Teile Acetaldiehyd, gelöst in ioo Teilen Dimethylfo@rinad, hinzu und fährt zugleich mit dem Einleiten, von. Acetylen, fotrt. Nach Zusatz von weiiteiren io Teilen Acetylen, zersetzt man dass Reaktionsprodukt mit Wasser. Man erhält so Propiri, (1)@dsmethy1-(3, 3)- 01-(3) mit einer Ausbeute von 25 0/0. Beispiel 2 Man mischt 15o Teilei gepulvertes Kalium- hydroxyd mit 5oo Teilen Dimethylacetat bei etwa 15°'. Man kühlt die Mischung auf io° ab und leitet dann etwa 2o Teile Acetylen ei'ni. Sodann setzt man; allmählich roo Teile Cycloheixan(on zu, indem man mit dem Einleiten von Acotylen fortfährt. Nach dem Zusatz dies ganzen; Cycloheixanons zeir- setzt man das Reaktionserzeugnis durch Zugabe von, etwa Zoo Teilen. Wasser. Darauf gießt man die beidem, Schichten(, die sich gebildet haben, vonieiin,- and.eir ab. Durch Destillation der oberen Schicht erhält man mit einer Ausbeute von wenigstens 8o % Äthinyl- cycloh!exanol der Formel (I), Schmelzpunkt F'.=31 his 32°, Sie-d4--p-unkt E. bei 4omm Quecksilbersäule =9q:', bei 13-o mm Ouecks.ilbersäule=ii3°. Als Nebenprodukt erhält man, Äthinyl-,dicyclohexanol der Formel (II) mit einem Schmelzpunkt F. von 103" und einem Siedepunkt E. von, 2o8°, Beisp iel 3 Wenn man nach Beispiel :2 arbeitet, aber bei einer nicht so niedrigen Temperatur, so vergrößert man die Ausbeute an; Äthiniyl-dicyclohexanol, z. B. er- hält man bejim Arbeiten bei +3o° diese Verbindüng mit eineu Ausbeute von 70% und mehr. Beisp iel 4 Man mischt 14o Teile gepulvertes Kalitun- hydroxyd mit Zoo Teilen D@isnethyl.acetal bei etwa 15°. Dairauf kühlt man auf etwa -io°' ab. und setzt io Teile Methyl-(2)-buten-(i)-in-(3) zu. So- dann fügt man allmählich eine Mischung von 64 Ten.len Aceton; und 7o Teilen, Methyl-(2)- buten-(i)-in-(3) hinzu. Nachdem die ganze Mischung zugesetzt ist, zersetzt man .das Erzeugnis mit Wasser. Die wäßrige Schlicht wird, abgegossen. Durch Destillation: der organischen. Schicht eirhält man mit einer Ausbeute von 8o% oder mehr das Di- methyl-(2, 5)-hexen-(1)-in-(3)-01-(5) Diese Verhin(dung siedet beii i59 bis i 6o° unter ge- wöhnlichem Druck, und bell 11o° unter einem Druck von 130 mm. Beis,piel5 Arbeitet man wie in dem vorigen Beispiel, aber indem man das Aceton durch 8o Teile Methyläthyl- leton ersetzt, so erhält man das Dimethyl-(2, 5)- hep.ten-(i) -iin-(3)-01-(5) mit :dem Siedepunkt E. bei 130 mm Quecksilber- säule= 118. Process for the production of acetylene carbinols Gege @ nsta, nd: des- patent 86aoo5 is a process for the production of, propyne- (i) -d methyl- (3, 3) -Ol- (3) by addition of acetone to acetylene in the presence of: pulverized potassium hydroxide, calcium hydroxide and organic: The method # consists in using an acetal or a tertiary amine as solvent, adding powdered potassium hydroxide and a portion of the acetylene, at a maximum of about, o ° add the acetone and then the rest of the acetylene, decompose the resulting potassium compound of the carbinol with water and work it up as usual. The invention relates to a further embodiment of the aforementioned method, with one in place from acetone to aliphatic ketones or cyclic ones Ketones, such as cyclohexanone, or aliphatic Aldehyd'.e, or that instead of acetylene one is mono, - sub, institutional products used. The "reaction" can take place at about 0 °, it leaves but can also be carried out at lower temperatures. Example i Ma, n @ mixes 175 parts of powdered calcium hyd: roxyd, with 500 parts of dimethyl formal in one Temperature of about 15'0, lets the temperature up to about 3o to 33 °, rise, the mixture cools about & from, and then derives., about 20 parts Aceityleni a. Then you gradually add 45 parts Acetaldehyde, dissolved in 100 parts of dimethylfo @ rinad, and continues at the same time with the introduction of. Acetylene, photrt. After adding further 10 parts Acetylene, the reaction product is decomposed with Water. This gives Propiri, (1) @ dsmethy1- (3, 3) - 01- (3) with a yield of 25 0/0. Example 2 Mix 15o egg powdered potassium hydroxyd with 500 parts of dimethyl acetate at about 15 ° '. The mixture is cooled to 10 ° and passed then about 20 parts acetylene ei'ni. Then sets one; gradually roo parts of cycloheixan (on to by one continues with the introduction of acetylene. After adding all of this; Cycloheixanons zir- one sets the reaction product by adding from, about zoo parts. Water. They are poured onto it both, layers (which have formed, from one, - and.eir off. Distilling the top layer gives with a yield of at least 8o% ethynyl Cyclohexanol of the formula (I), melting point F. = 31 up to 32 °, Sie-d4 - point E. at 4omm mercury column = 9q: ', at 13-o mm square silver column = ii3 °. as By-product is obtained, ethynyl, dicyclohexanol of formula (II) with a melting point F. of 103 "and a boiling point E. of, 2o8 °, Example 3 If you work according to example: 2, but at a not so low temperature, you increase the yield; Ethyl dicyclohexanol, e.g. B. he one keeps this connection when working at + 30 ° with a yield of 70% and more. Example 4 One mixes 14o parts of powdered potassium hydroxyd with zoo parts D@isnethyl.acetal at about 15 °. Dairauf cools down to about -io ° '. and adds 10 parts of methyl- (2) -butene- (i) -yne- (3). So- then one gradually adds a mixture of 64 Ten.len acetone; and 7o parts, methyl- (2) - buten- (i) -in- (3) added. After the whole Mixture is added, one decomposes .the product with water. The aqueous size is poured off. By Distillation: the organic. Shift is held with a yield of 80% or more the di- methyl- (2, 5) -hexen- (1) -in- (3) -01- (5) This prevention boils at i 59 to i 60 ° below ordinary pressure, and bell 11o ° under one Print of 130 mm. Beis, play5 If you work as in the previous example, but by replacing the acetone with 8o parts of methyl ethyl replaces leton, one obtains the dimethyl- (2, 5) - hep.ten- (i) -iin- (3) -01- (5) with: the boiling point E. at 130 mm mercury pillar = 118.
