REACTION SYSTEMS FOR MAKING N-(PHOSPHONOMETHYL)GLYCINE COMPOUNDS |
| 摘要 |
<p num="1"><br/><br/><br/>This invention generally relates to liquid-phase oxidation processes for <br/>making N-(phosphonomethyl)glycine (also known in the agricultural chemical <br/>industry as glyphosate) and related compounds. This invention, for example, <br/>particularly relates to processes wherein an N-(phosphonomethyl)iminodiacetic <br/>acid (NPMIDA) substrate (i.e., N-(phosphonomethyl)iminodiacetic acid, a salt <br/>of N-(phosphonomethyl)iminodiacetic acid, or an ester of N-<br/>(phosphonomethyl)iminodiacetic acid) is continuously oxidized to form an N-<br/>(phosphonomethyl)glycine product (i.e., N-(phosphonomethyl)glycine, a salt of <br/>N-(phosphonomethyl)glycine, or an ester of N-(phosphonomethyl)glycine). This <br/>invention also, for example, particularly relates to processes wherein an N-<br/>(phosphonomethyl)iminodiacetic acid substrate is oxidized to form an N-<br/>(phosphonomethyl)glycine product, which, in turn, is crystallized (at least in <br/>part) in an adiabatic crystallizer.<br/></p> |
