Abstract

Reivindicacion 1: Un polimorfo cristalino Forma 3 de 2-[4-metilsulfonil-2-nitrobenzoil]-1,3-ciclohexanodiona que exhibe al menos una de las siguientes propiedades: (a) un patron de difraccion de polvo de rayos X que posee un pico característico expresado en 2theta (+- 0,20s2theta) a 8,0, dicho pico se caracteriza por tener la intensidad más alta; (b) un espectro de absorcion infrarrojo (IR) que posee al menos un pico característico seleccionado de los siguientes valores expresados como cm-1 (+- 1cm-1): 732, 770, 793, 891, 967, 1121, 1152, 1291, 1304 y 2952; (c) RMN de 13C en estado solido con al menos una de las siguientes características: (i) desviaciones químicas de la RMN de 13C en estado solido, con referencia a un valor de 176,03 ppm para el pico de carbonilo de glicina, teniendo tres picos en el rango de 191 a 197 ppm (+- 0,1 ppm); (ii) RMN de 13C en estado solido, expresada como la diferencia entre el pico de desviacion química de metileno de carbono de menor valor y los demás valores de desviacion química, que poseen tres picos en el rango de 171,4 a 177,4 ppm (+- 0,1 ppm). Reivindicacion 13: Un proceso para la preparacion de un polimorfo cristalino Forma 3 de 2-[4-metilsulfonil-2-nitrobenzoil]-1,3- ciclohexanodiona segun cualquiera de las reivindicaciones 1 a 12, que comprende: (a) la cristalizacion de la Forma 3 de una solucion acuosa que comprende (i) una sal de amonio de 2-[4-metilsulfonil-2-nitrobenzoil]-1,3-ciclohexanodiona y (ii) un disolvente polar aprotico seleccionado de dimetilsulfoxida (DMSO), N-metil-2- pirrolidona (NMP), dimetilformamida (DMF), y mezclas de dichos solventes, por acidificacion de dicha solucion; y (b) aislar el precipitado resultante de la Forma 3. Reivindicacion 17: Una composicion herbicida que comprende un polimorfo cristalino Forma 3 de 2-[4-metilsulfonil-2-nitrobenzoil]-1,3-ciclohexanodiona segun cualquiera de las reivindicaciones 1 a 12; y un diluyente o vehículo herbicidamente aceptable.
