| titleOfInvention | Method of producing cinnamic acids |
| abstract | The invention relates to the production of unsaturated aromatic acids, in particular the preparation of cinnamic acids, used to synthesize formatizing preparations, pesticides, preservatives, and bactericidal compositions. The goal is to increase the yield of the target product and simplify the process. The latter is carried out by condensation of benzaldehyde or its derivatives with acetic anhydride in the presence of a catalyst, a complex of poly (dibenzo-18-crown-6-co-formaldehyde) with potassium acetate or potassium fluoride at their molar ratio of 1: (2-3) :( 0, 04-0.08) and 80-120 ° C. These conditions increase the yield of cinnamic acid by 11-26% (up to 81-96%) as compared with the known method. The use of a polymer catalyst simplifies the process due to its repeated use and ease of regeneration. 1 tab. |
