Abstract
Description
Oppfinnelsen vedrører en ny fremgangsmåte for fremstilling av krotonbetainhydroklorid fra karnitinhydroklorid, spesielt fra racemisk karnitinhydroklorid eller fra D-karnitinhydroklorid. The invention relates to a new process for producing croton betaine hydrochloride from carnitine hydrochloride, in particular from racemic carnitine hydrochloride or from D-carnitine hydrochloride.
Krotonbetainhydroklorid anvendes blant annet som utgangs-produkt ved den mikrobiologiske syntese av L-karnitin, sammen-lign f.eks. EP-A 0 158 194 eller EP-A 0 122 794. Croton betaine hydrochloride is used, among other things, as a starting product in the microbiological synthesis of L-carnitine, compare e.g. EP-A 0 158 194 or EP-A 0 122 794.
Det er ifølge Chemical Abstracts Vol. 59, 6248 (Binon et al.) kjent å fremstille krotonbetainhydroklorid i 78%-ig utbytte utifrå D,L-karnitinklorid ved omsetning med konsentrert svovelsyre ved 130°C, påfølgende utfelling med aceton og be-handling med bariumklorid. En stor ulempe ved denne fremgangsmåten er ved siden av håndteringen av konsentrert svovelsyre, det bariumsulfat som fremkommer og som ikke er re-sirkulerbart. According to Chemical Abstracts Vol. 59, 6248 (Binon et al.), it is known to produce crotonbetaine hydrochloride in 78% yield from D,L-carnitine chloride by reaction with concentrated sulfuric acid at 130°C, subsequent precipitation with acetone and treatment with barium chloride. A major disadvantage of this method is, in addition to the handling of concentrated sulfuric acid, the barium sulphate which is produced and which cannot be recycled.
Videre oppstår ved den klassiske kjemiske fremstilling av L-karnitin ved racematseparasjon, f.eks. ifølge DD 23.217, tvangsmessig det problem at D-karnitin fremkommer som biprodukt, som tidligere ikke hadde noen videre anvendelse. Furthermore, in the classic chemical preparation of L-carnitine by racemate separation, e.g. according to DD 23.217, forced the problem that D-carnitine appears as a by-product, which previously had no further application.
Oppgaven var derfor å finne en fremgangsmåte som ute-lukker de nevnte ulempene. Oppgaven kunne løses med en fremgangsmåte ifølge patentkrav 1. The task was therefore to find a method which excludes the aforementioned disadvantages. The task could be solved with a method according to patent claim 1.
Deri blir etter valg racemisk karnitinhydroklorid, D-karnitinhydroklorid eller også L-karnitinhydroklorid omsatt med 1,5 til 15 mol eddiksyreanhydrid i nærvær av en sur katalysator ved en temperatur på 90 til 130°C. Fortrinnsvis anvendes naturligvis det D-karnitin som fremkommer som biprodukt ved den klassiske L-karnitinsyntese eller det kostnadsgunstige D,L-karnitin. In this case racemic carnitine hydrochloride, D-carnitine hydrochloride or also L-carnitine hydrochloride is reacted with 1.5 to 15 mol of acetic anhydride in the presence of an acid catalyst at a temperature of 90 to 130°C. Preferably, of course, the D-carnitine that appears as a by-product in the classical L-carnitine synthesis or the cost-effective D,L-carnitine is used.
Fortrinnsvis velger man eddiksyreanhydridmengder i om-rådet fra 1,8 til 2 mol. Acetic anhydride amounts are preferably chosen in the range from 1.8 to 2 mol.
Som sur katalysator anvendes fortrinnsvis p-toluensulfonsyre i en mengde på 0,5 til 2 vekt-%, i forhold til det anvendte karnitinhydroklorid. As acid catalyst, p-toluenesulfonic acid is preferably used in an amount of 0.5 to 2% by weight, in relation to the carnitine hydrochloride used.
Reaksjonstemperaturen ligger fortrinnsvis mellom 110 og 125°C, spesielt foretrekkes mellom 115 og 120°C. Ved denne temperaturen er omsetningen som regel ferdig etter ca. 2 timer. The reaction temperature is preferably between 110 and 125°C, particularly preferably between 115 and 120°C. At this temperature, the turnover is usually complete after approx. 2 hours.
Ved tilsetning av en lavere alifatisk alkohol, fortrinnsvis etanol, til den varme, fortrinnsvis 70 til 80"C varme reaksjonsblandingen og ved påfølgende avkjøling, kan krotonbetainhydrokloridet felles ut på fordelaktig måte og isoleres med en allerede høy renhet. By adding a lower aliphatic alcohol, preferably ethanol, to the hot, preferably 70 to 80"C hot reaction mixture and by subsequent cooling, the croton betaine hydrochloride can be advantageously precipitated and isolated with an already high purity.
Etter fremgangsmåten ifølge oppfinnelsen kan oppnås ut-bytter på over 70%. According to the method according to the invention, yields of over 70% can be achieved.
Krotonbetainhydrokloridet kan avsaltes på vanlig måte, f.eks. ved elektrodialyse, og overføres til krotonbetain. The croton betaine hydrochloride can be desalted in the usual way, e.g. by electrodialysis, and is transferred to crotonbetaine.
Produktet som er fremstilt etter fremgangsmåten ifølge oppfinnelsen, egner seg på spesiell måte for anvendelse ved den mikrobiologiske fremstilling av L-karnitin. The product which is produced according to the method according to the invention is particularly suitable for use in the microbiological production of L-carnitine.
Eksempel Example
25,0 g (0,125 mol) D,L-karnitinhydroklorid, 0,25 g 25.0 g (0.125 mol) D,L-carnitine hydrochloride, 0.25 g
(1,5 mmol) p-toluensulfonsyre og 25,0 g (0,245 mol) eddiksyreanhydrid ble oppvarmet i 2 timer til 120°C. Man lot den mørk-fargede løsningen få avkjøle seg til ca. 80°C, og tilsatte 20 ml etanol. Deretter avkjølte man langsomt videre, hvorved produktet begynte å falle ut. Ved hjelp av et isvannbad ble oppslemmingen avkjølt til ca. 6°C, suget av og ettervasket med en liten mengde kald etanol. Produktet ble tørket under vakuum. (1.5 mmol) of p-toluenesulfonic acid and 25.0 g (0.245 mol) of acetic anhydride were heated for 2 hours at 120°C. The dark-colored solution was allowed to cool to approx. 80°C, and added 20 ml of ethanol. It was then slowly further cooled, whereby the product began to precipitate. Using an ice water bath, the slurry was cooled to approx. 6°C, aspirated off and washed with a small amount of cold ethanol. The product was dried under vacuum.
Man oppnådde 17,4 g beige-farget pulver med en renhet på 96% (HPLC). Dette tilsvarte et utbytte på 73,5%. 17.4 g of beige-colored powder with a purity of 96% (HPLC) was obtained. This corresponded to a yield of 73.5%.
