| titleOfInvention | The removing method of toluene |
| abstract | The present invention relates to the removing method of the solvent used in the manufacture of a kind of sucrose aromatic carboxylic acid esters, it includes using the vacuum drying apparatus of more than to make the pressure in exsiccator and/or heating-up temperature that the change of more than two benches at least to occur, mixture containing sucrose aromatic carboxylic acid esters and this solvent is carried out a succession of drying under reduced pressure operation of drying under reduced pressure, in the exsiccator of the first stage of this drying under reduced pressure operation, pressure is below atmospheric pressure, heating-up temperature is more than 20 DEG C, less than 250 DEG C, in the exsiccator of terminal stage, pressure is at below 10kPa abs, and heating-up temperature is more than 80 DEG C, less than 250 DEG C, by the removing method of this solvent, the sucrose aromatic carboxylic acid esters minimum almost without painted and solvent residual quantity can be obtained. |
