実験手順
A process for the manufacture of the trimethylsulfonium salt of N-phosphonomethylglycine which comprises (i) treating trimethylsulfonium hydrogen sulfate with sodium hydroxide to precipitate sodium sulfate (ii) bubbling carbon dioxide through the resultant aqueous solution of trimethylsulfonium hydroxide to form trimethylsulfonium bicarbonate or carbonate or a mixture thereof, (iii) removing the precipitated sodium sulfate either after stage (i) or stage (ii), (iv) optionally obtaining the trimethylsulfonium bicarbonate or carbonate or the mixture thereof as a transportable solid or concentrated aqueous solution, and (v) reacting
