| titleOfInvention | A new synthesis process of trozole trisiloxane cresol |
| abstract | The invention provides a new process for synthesizing trozole trisiloxane, which belongs to the technical field of fine chemical synthesis. Under the conditions, reflux reaction with methallyl chloride for 2-3 hours, Friedel-Crafts alkylation reaction and Friedel-Crafts-alkylation reaction to synthesize intermediate A; Step 2, the intermediate A obtained in step 1 is in reaction solvent b , under the condition of platinum catalyst, hydrosilylation reaction occurs with heptamethyltrisiloxane for 3-5 hours to synthesize intermediate B; the intermediate B obtained in step 3 and step 2 and o-nitroaniline have a diazo-coupling reaction , through post-processing to obtain intermediate C; the intermediate C obtained in step 4 and step 3 is subjected to reductive cyclization reaction, and the crude product is directly obtained by reduction, and then the refined product is obtained through recrystallization, dried, and packaged to obtain the final product. The invention has the advantages of short time, high efficiency, low cost, safe reaction, high conversion rate and low requirements for industrialization. |
