Definitions
- the invention relates to improvements made in a process for obtaining N-phosphononylglycine by oxidation of N-phosphonomethyliminodiacetic with oxygen or an oxygen-containing gas, used as a catalyst. a noble metal supported on active carbon.
- the improvements of the invention refer to the realization of a treatment aimed at minimizing the losses of the noble metal catalyst that occur in this type of reactions.
- an object of the invention is to introduce improvements in a known method of obtaining Nf osf onomethyl glycin by oxidizing N-phosphonomethyliminodiacetic in the presence of a noble metal supported on activated carbon as a catalyst, - causing such improvements that the losses of noble metal are minimized, by performing a treatment aimed at recovering almost all of the catalyst used without loss of its catalytic activity. . . BRIEF DESCRIPTION AND THE INVENTION
- the improvements of the invention can be realized in that the losses of the noble metal catalyst used in obtaining N-phosphonomethyl glycine are minimized by oxidation of the N-phosphonomethyliminodiacetic. To minimize these losses, the invention proposes Take a sweep with N «once the oxidation reaction has ended.
- the noble metal content in the reaction solution is achieved to be less than 1 ppm. against a content of the same superior to 70 ppm. that would be obtained in said solution if the aforementioned sweeping with 2 was not carried out . Therefore, this sweep with 2 minimizes the losses of the noble metal by lowering them by percentages of up to £ 30 to losses less than 1 making this type of procedure economically viable. Obtaining these improvements will be mentioned in more detail in the description that follows.
- the invention provides a series of improvements or improvements to minimize losses of noble metal used as a catalyst in known processes for obtaining N-f osf onomethylgli ci a by oxidation of - N-phosphonomethyliminodiacetic.
- a process for obtaining Nf osf onomethylgli ci ⁇ a is described which can be schematized according to the following equation and in which for simplicity the palladium on carbon is listed as a catalyst :
- the initial concentration of N-phosphonomethyliminodiacetic - can be between 4 $ and 15 ⁇ * by weight, preferably between 4 - and i% by weight since higher concentrations decrease reaction performance and concentrations Lower decrease productivity.
- the percentage of the catalyst against N-phosphonomethylimonoxadiacetic can vary between 4 ⁇ and 1 ⁇ by weight, although with an average percentage of 6 it is possible to obtain - good results.
- - Pd / C has been used as catalyst.
- Such treatment can be summarized in that, in a single step and once * finali_ Zada reaction in oxygen or a gas which - contains oxygen, the reaction solution obtained is des ⁇ pressurized and is flushed twice with nitrogen, in order to eliminate all possible oxygen from the reaction.
- a - then the reaction is pressurized again with 9 to - 9 pressures between 0.5 Kg / cm and 5 Kg / cm, preferably between 1 and 2 Kg / cm and maintaining this pressure - the step of nitrogen with a flow of 10 to 30 - liters / minute, preferably 25 l nin., for a period of time between 15 minutes and 1 hour.
- the flow rate (l / min.) Of 2 will depend on the scaling of the process.
- the passage time of 2 is a function of the temperature at which the reaction solution is and can be between 202C and 20C, since the reaction mixture once pressurized with 2 can be heated or alternatively this Treatment can be carried out at the temperature of the oxidation reaction without the need to heat the reaction solution. It has been found that for a reaction solution temperature of 11 C - the passage time of N «is 30 minutes to obtain a Pd content of 0.9 ppm in said solution and that at a temperature of 1002C the time the passage is 45 minutes to obtain a content of 0.6 ppm in said solution.
- the recovered catalyst maintains its catalytic activity and can be reused for at least 20 vecer * consecutive without losing its "activity without varying the yields.
- GOT entity through the perfeccionami ents of this invention is possible to obtain N-fosfonometilgli 'ce by - oxy dation of N-phosphonomethyliminodiacetic, a trial indus ⁇ level with adequate purity and yield and it is possible to recover the noble metal catalyst used without loss of its catalytic activity by a simple trata ⁇ tion that does not require the installation of complex equipment.
- EXAMPLE 2 This experiment was carried out to determine the influence of temperature on the recovery process - of the palladium dissolved in the reaction solution. The experiment was carried out with the same methodology used in Example 1 for the reaction. As for the post-reaction treatment for palladium recovery, it was carried out at a temperature equal to that of the reaction (100SC) and the time taken for the dissolved palladium to be less than 1 ppm (0.6 ppm) in The reaction water was 45 minutes. The yield of N-phosphonomethyl glycine of a purity - higher than 977 * was 1,440 kg (yield 95.6). Having described the object of the present invention, it is stated - that what constitutes the essentiality thereof is what is mentioned in the following:
