(64) Fremgangsmåde til fremstilling af alkalimetal- eller jordalkalimetal« salte af ligekædede alifatiske monoestere af kulsyre.(64) Process for the preparation of alkali metal or alkaline earth metal salts of straight chain aliphatic carbonic acid monoesters.
Den foreliggende opfindelse angår en fremgangsmåde til fremstilling af alkalimetal- eller jordalkalimetalsalte af ligekædede alifatiske monoestere af kulsyre med formlenThe present invention relates to a process for the preparation of alkali metal or alkaline earth metal salts of straight chain aliphatic carbonic acid monoesters of the formula
( RO - C - 0)n Me O(RO - C - 0) n Me O
hvori R betegner en ligekædet, mættet eller umættet,alifatisk car-bonhydridgruppe, n er 1 eller 2, og Me betegner et alkalimetal- eller jordalkalimetalatom, hvilken fremgangsmåde er ejendommelig ved, at man omsætter en tilsvarende alkohol med formlen ROH, hvori R har den ovennævnte betydning, med carbondioxid og med et alkalimetal-eller jordalkalimetalcarbonat eller -oxid under et C02”tryk i området fra 0 til 100 atmosfærer og ved en temperatur mellem den an- 2 142749 vendte alkohols frysepunkt og kogepunktet, hvorefter man fraskiller det opnåede produkt ved udfældning og filtrering eller ved afdampning af reaktionsmediet, vasker det og tørrer det.wherein R represents a straight-chain, saturated or unsaturated aliphatic hydrocarbon group, n is 1 or 2, and Me represents an alkali metal or alkaline earth metal atom which is characterized by reacting a corresponding alcohol of formula ROH wherein R has it the above-mentioned meaning, with carbon dioxide and with an alkali metal or alkaline earth metal carbonate or oxide under a CO 2 precipitate and filtration or by evaporation of the reaction medium wash it and dry it.
Omsætningen, der foregår efter følgende reaktionsskema:The reaction is carried out according to the following reaction scheme:
Me X + n CO- + nROH -XROCOO) Me + Η X Mem , m2 n n m-l 2 b hvori Me, R og n har de ovennævnte betydninger, X betegner CO-2*· 3 eller 0 , og m er 1 eller 2, kan simpelthen udføres ved at lade en CO2“strøm boble gennem en opløsning eller suspension af det valgte salt i den pågældende alkohol, fortrinsvis under omrøring. Temperaturen holdes som nævnt mellem alkoholens frysepunkt og kogepunkt, dog fortrinsvis mellem 0 og 60°C.Me X + n CO- + nROH -XROCOO) Me + Η X Mem, m2 nn ml 2 b wherein Me, R and n have the above meanings, X represents CO-2 * · 3 or 0 and m is 1 or 2 , can be performed simply by bubbling a CO2 stream through a solution or suspension of the selected salt in the alcohol in question, preferably with stirring. As mentioned, the temperature is maintained between the freezing point and the boiling point of the alcohol, but preferably between 0 and 60 ° C.
Omsætningen kan udføres i nærværelse af alene alkoholen som reaktionsmedium. Alt efter reaktionsprodukternes opløselighedsfor-hold kan omsætningen, med henblik på isoleringen, også udføres i nærværelse af et opløsningsmiddel, der er indifferent med hensyn til reaktionen. Der kan dog også med henblik på udfældning af reaktionsprodukterne tilsættes et egnet opløsningsmiddel efter reaktionen.The reaction may be carried out in the presence of the alcohol alone as the reaction medium. Depending on the solubility ratio of the reaction products, the reaction, for the purpose of isolation, can also be carried out in the presence of a solvent inert to the reaction. However, a suitable solvent may also be added after the reaction to precipitate the reaction products.
De omhandlede salte kan anvendes i stedet for de tilsvarende alkoholater ved kondensationsreaktioner, f.eks. ved kondensation af aldehyder med molekyler indeholdende aktivt hydrogen, eller af estere med urinstoffer, eller som katalysatorer ved disproportioneringsreaktioner med aromatiske aldehyder.The salts in question can be used in place of the corresponding alcoholates in condensation reactions, e.g. by condensation of aldehydes with molecules containing active hydrogen, or of esters with urea, or as catalysts in disproportionation reactions with aromatic aldehydes.
Ved de ovennævnte reaktioner udøver de ved fremgangsmåden ifølge opfindelsen opnåede salte, sammenlignet med alkoholaterne, en mindre drastisk virkning, således at sidereaktionerne begrænses, og lavere omkostninger bliver-resultatet.In the above reactions, the salts obtained by the process according to the invention, compared with the alcoholates, exert a less drastic effect, thus limiting the side reactions and resulting in lower costs.
Fremgangsmåden ifølge opfindelsen belyses nærmere ved hjælp af de efterfølgende eksempler.The process according to the invention is further elucidated by the following examples.
Eksempel 1 10 g vandfrit K2C03 opslemmes i 100 ml vandfrit methanol, og man lader en strøm af C02 i en lidt større mængde end den, der absorberes, boble gennem opslemningen under kraftig omrøring ved 25°C.EXAMPLE 1 10 g of anhydrous K
Reaktionen er både exoterm og hurtig og er afsluttet inden for 30 minutter. Efter endt absorption opsamles det af KHC03 bestående bundfald på et filter, og opløsningen inddampes i vakuum. Der opnås 8,5 g urent K0C00CH3, da det indeholder spor af KHC03.The reaction is both exothermic and rapid and is completed within 30 minutes. Upon completion of the absorption, the KHCO3 precipitate is collected on a filter and the solution is evaporated in vacuo. 8.5 g of impure K0C00CH3 is obtained as it contains traces of KHCO3.
