| titleOfInvention | Separation of active ingredients in terephthalic acid residues by sublimation |
| abstract | The present invention relates to a method for separating the active ingredient in the terephthalic acid residue (Terephthalic Acid Residue), and more particularly, by using the sublimation method, benzoic acid (Benzoic acid), p-toluic acid (p-Toluic Acid), It relates to a method for selectively separating 4-carboxybenzaldehyde (4-Carboxybenzaldehyde) and the like.n n n According to the present invention, the active ingredient in the terephthalic acid residue is i) a washing step of removing the organometallic compound and the catalyst by washing and filtering the terephthalic acid residue with water; ii) a drying step of drying the terephthalic acid residue from which the organometallic compound and the catalyst have been removed; And iii) separating the dried terephthalic acid residue into a sublimation apparatus to separate the active ingredient.n n n Crude terephthalic acid residue, refined terephthalic acid residue, sublimation method |
