| titleOfInvention | Method of production of 1,8-octanediol |
| abstract | The invention relates to polyhydric alcohols, in particular the preparation of 1,8-octanediol, which is a key synthon in the synthesis of a number of pheromones. The goal is to increase the yield of the target product. The preparation is carried out by the reaction of diisobutyl aluminum hydride with 1.7-octanedienes at 20–30 ° C for 4–8 h in the presence of a catalyst. The components of the latter are introduced in the following sequence: zirconium tetrachloride, then butyl alcohol and tetrabutoxy zirconium, and these reagents and catalyst components are taken in the following molar ratios: (260-200): 100: (1-3):: (4 -12) :( 1-31. The resulting mass is subjected to air oxidation for 1 hour at (-5) - (+ 30) ° C, oxygenated for 4 hours at 40-50 ° C and then a guide Rolled with water. The process is carried out in an inert organic solvent. 1 ta bl. |
