Description
Foreliggende oppfinnelse angår en fremgangsmåte ved fremstilling av forbindelser som har fosfor-carbon-nitrogen-binding, spesielt N-fosfono-methylglycin og derivater derav, idet de sistnevnte forbindelser er kjent i miljøvernet som herbicid aktive forbindelser. The present invention relates to a method for the production of compounds having a phosphorus-carbon-nitrogen bond, in particular N-phosphono-methylglycine and derivatives thereof, the latter compounds being known in environmental protection as herbicidally active compounds.
Forbindelsene som inneholder fosfor-carbon-nitrogen-binding, har vært vidt anvendt i plantevernet på grunn av en herbicid aktivitet med et vidt spektrum. Den herbicide aktivitet er ledsaget av lav gjenværende aktivitet, dvs. den aktive bestanddel spaltes relativt lett i jorden. The compounds containing a phosphorus-carbon-nitrogen bond have been widely used in plant protection due to a broad-spectrum herbicidal activity. The herbicidal activity is accompanied by low residual activity, i.e. the active ingredient breaks down relatively easily in the soil.
Flere syntetiske fremgangsmåter har tidligere vært an-gitt for fremstillingen av fosfor-carbon-nitrogen-binding-holdige forbindelser, fortrinnsvis N-fosfono-methylglycin og derivater derav. Several synthetic methods have previously been indicated for the production of phosphorus-carbon-nitrogen bond-containing compounds, preferably N-phosphono-methylglycine and derivatives thereof.
GB patentskrift nr 1 142 294 vedrører fremstilling av aminoalkylenfosfonsyrer ved omsetning av ammoniakk eller et alifatisk amin med et aldehyd eller keton og et fosfortrihalogenid i nærvær av 2,0 - 7,0 mol vann pr. mol fosfortrihalogenid. Det foretrukne molare forhold mellom vann og fos-fostrihalogenid er 3,5 - 5,5:1. Ifølge linje 13 - 15 på side 2 i beskrivelsen er det ikke ønskelig med for mye vann ettersom reaksjonshastigheten derved reduseres mye. I eksemplene er bare fremstillingen av amin-tris-methylenfosforsyre vist å gi et utbytte som når opp i 85 - 95%, andre derivater fåes imidlertid bare i et utbytte på 68% (jfr. eksempel 5). GB patent no. 1 142 294 relates to the production of aminoalkylenephosphonic acids by reacting ammonia or an aliphatic amine with an aldehyde or ketone and a phosphorus trihalide in the presence of 2.0 - 7.0 mol of water per moles of phosphorus trihalide. The preferred molar ratio of water to phosphorus trihalide is 3.5 - 5.5:1. According to lines 13 - 15 on page 2 of the description, it is not desirable to use too much water, as the reaction rate is thereby greatly reduced. In the examples, only the production of amine-tris-methylenephosphoric acid is shown to give a yield that reaches 85 - 95%, other derivatives, however, are only obtained in a yield of 68% (cf. example 5).
Foreliggende oppfinnelse er basert på den erkjennelse The present invention is based on that realization
at fra 25 til 32 mol vann pr. mol fosfortriklorid bør være til stede for å oppnå utbytter som kommer opp i mer enn 90% that from 25 to 32 mol of water per moles of phosphorus trichloride should be present to obtain yields that reach more than 90%
når det fremstilles forbindelser som inneholder fosfor-carbon-nitrogen-binding ifølge den generelle formel I nedenunder, when preparing compounds containing a phosphorus-carbon-nitrogen bond according to the general formula I below,
ved omsetning ifølge den nedenfor angitte fremgangsmåte. by turnover according to the procedure specified below.
I BRD off.skrift nr. 2 021 148, som svarer til FR patentskrift nr. 2 090 873, beskrives en kontinuerlig fremgangsmåte for oppnåelse av aminalkylenfosforsyre ved omsetning av ammoniakk eller et aminsalt i form av et hydrohalogensyre-salt derav, med fosfortriklorid eller fosforsyrling og formaldehyd i støkiometrisk forhold, i fortrinnsvis minst to trinn og ved to temperaturnivåer (40 - 60°C og ved kokepunktet til reaks jonsblandingen). Det vesentlige ved denne fremgangsmåte er ikke bruken av fosfortrihalogenid og vann i stedet for fosforsyrling i visse forhold, ettersom det ikke er noen for-skjell mellom omsetning av fosfortrihalogenid og fosforsyrling med de øvrige bestanddeler. Fremgangsmåten ifølge foreliggende oppfinnelse utføres satsvis med et utbytte som er bedre enn det som oppnåes ifølge det franske patentskrift. BRD official document no. 2 021 148, which corresponds to FR patent document no. 2 090 873, describes a continuous process for obtaining amine alkylene phosphoric acid by reacting ammonia or an amine salt in the form of a hydrohalic acid salt thereof, with phosphorus trichloride or phosphoric acid and formaldehyde in stoichiometric ratio, in preferably at least two stages and at two temperature levels (40 - 60°C and at the boiling point of the react ion mixture). The essential thing about this method is not the use of phosphorus trihalide and water instead of phosphoric acidification in certain conditions, as there is no difference between reaction of phosphorus trihalide and phosphoric acidification with the other components. The method according to the present invention is carried out in batches with a yield that is better than that obtained according to the French patent document.
I fransk patentskrift nr. 91049 beskrives en lignende fremgangsmåte som den ifølge GB patentskrift nr. 1 142 294. Det molare forhold mellom fosfortriklorid og vann som skal French patent document no. 91049 describes a similar method to that according to GB patent document no. 1 142 294. The molar ratio between phosphorus trichloride and water which must
til for å danne aminalkylenfosforsyrer, lar seg beregne til 12. På samme måte som foreliggende oppfinnelsen er avgrenset i forhold til det motholdte britiske patentskrift, er den også skarpt avgrenset i forhold til det som er beskrevet i fransk patentskrift nr. 91049. to form aminoalkylene phosphoric acids, can be calculated to 12. In the same way that the present invention is delimited in relation to the opposed British patent document, it is also sharply delimited in relation to what is described in French patent document no. 91049.
GB patentskrift nr. 1 125 977 vedrører en fremgangsmåte for fremstilling av nitril-tris-methylenfosfonsyre ved anvendelse av ammoniakk eller et ammoniumsalt sammen med formaldehyd og fosfortriklorid i en vandig oppløsning, og i et molart forhold som ligger mellom 70 og 200%. Det molare forhold mellom PCl^ og vann er ikke kritisk, slik som påberopt i foreliggende oppfinnelse, og utbyttet er dårlig. GB Patent No. 1 125 977 relates to a method for the production of nitrile-tris-methylenephosphonic acid using ammonia or an ammonium salt together with formaldehyde and phosphorus trichloride in an aqueous solution, and in a molar ratio between 70 and 200%. The molar ratio between PCl 2 and water is not critical, as claimed in the present invention, and the yield is poor.
Foreliggende fremgangsmåte har den fordel at man kan The present method has the advantage that one can
få et kjemisk homogent, rent produkt, og således er forbindelsene som inneholder fosfor-carbon-nitrogen-binding, ikke forurenset av dannede biprodukter som kjemisk ligner de ønskede produkter. Dette er av stor betydning da den plantefysio-logiske aktivitet av de homologe forbindelser er temmelig for-skjellig, og ved å fremstille et rent produkt kan en selek- ' tiv aktivitet oppnåes i stedet for den totalherbicide aktivitet med vidt spektrum. obtain a chemically homogeneous, pure product, and thus the compounds containing the phosphorus-carbon-nitrogen bond are not contaminated by formed by-products that are chemically similar to the desired products. This is of great importance as the plant physiological activity of the homologous compounds is quite different, and by producing a pure product, a selective activity can be achieved instead of the total herbicidal activity with a broad spectrum.
Foreliggende oppfinnelse er rettet på fremstillingen The present invention is directed to the production
av forbindelser med den generelle formel: of compounds with the general formula:
hvor og R^ er like eller forskjellige, og er fosfonomethyl, carboxymethyl, methyl, cyclohexyl eller N,N-difosfono-methylethyl-amino, ved hvilken fosfortriklorid omsettes med et vannoppløselig ammoniumsalt, glycin, N-methylglycin, imino-eddiksyre eller ethylendiamin og med formaldehyd, i nærvær av vann, og produktet utvinnes ved å redusere reaksjonsvolu-met eller ved å tilsette et med vann blandbart oppløsnings-middel til reaksjonsblandingen, hvilken fremgangsmåte er kjennetegnet ved at reaksjonen utføres i nærvær av fra 25 til 32 mol vann pr. mol fosfortriklorid. where and R^ are the same or different, and are phosphonomethyl, carboxymethyl, methyl, cyclohexyl or N,N-diphosphono-methylethyl-amino, whereby phosphorus trichloride is reacted with a water-soluble ammonium salt, glycine, N-methylglycine, imino-acetic acid or ethylenediamine and with formaldehyde, in the presence of water, and the product is recovered by reducing the reaction volume or by adding a water-miscible solvent to the reaction mixture, which method is characterized by the reaction being carried out in the presence of from 25 to 32 mol of water per moles of phosphorus trichloride.

Utbyttet utgjør over 90%, og for-holdet av forbindelsene som inneholder PCN-binding i det dannede produkt, er over 98%.
