| titleOfInvention | Process for the crystallization of dicarboxylic acids |
| abstract | The subject invention relates to a process for the crystallization of di-carboxylic acids comprising dissolving the crude dicarboxylic acid at a temperature sufficient to dissolve the crude diacid in the solvent, whereby portion of the said solvent evaporates, increasing the concentration of the dicarboxylic acid in the said solution, transferring the said solution from the evaporator to a crystallizer, comprising a solid cylindrical impeller conforming to the shape of the crystallizer related by means of a cylindrical shaft attached to the spped motor, adding the additives selected from surfactants, buffer salts and/or acid salts or mixture thereof in the said evaporated solution in the said crystallizer, cooling the said mixture resulting in the formation of crystals of dicarboxylic acids, wherein the said crystallization takes place in the annular space between the impeller and the crystallizer wall. |
