| titleOfInvention | A kind of preparation method of high-purity vanillin amine hydrochloride |
| abstract | The invention discloses a preparation method of high-purity vanillinamine hydrochloride. A calixarene capable of recognizing divanillinimine molecules is synthesized through aldol condensation, Friedel-Crafts reaction, etherification and sulfonation ; The calixarene reacts with the divanillinimine in the 97% vanillinamine hydrochloride through supramolecular action to form a divanillinimine-calixarene host-guest recognition supramolecular, which is precipitated after pH adjustment. separation to obtain a vanillin amine hydrochloride solution with a content higher than 99.8%, and after acidification and crystallization to obtain a vanillin amine hydrochloride product with a content higher than 99.8%; the purification method used in the present invention can be directly applied in production. , no need to add auxiliary materials, not much waste water, waste gas and waste residue, good calixarene cycle performance, green environmental protection and no pollution, in line with the concept of green chemistry and the development trend of atomic economy. |
