| titleOfInvention | A kind of synthetic method of organic synthesis raw material valeric acid |
| abstract | A kind of synthetic method of organic synthesis raw material valeric acid, mainly includes the following steps：The methyl propyl ketone of 3mol is added in reaction vessel, the tributyl citrate solution of 4 6mol, control 190 220rpm of mixing speed, solution temperature is reduced to 69 DEG C, keep 60 80min, then raising solution temperature is to 10 15 DEG C, divide the chromium acetates of 363 4mol of addition, each 30 40min of interval time, the reaction was continued 2 3h, then 60 80min are stood, add in 300ml potassium nitrate solutions, solution is layered, water layer is extracted 35 times with 4 heptanone solution, 3 methyl, 2 pentanone solution extracts 46 times, merge oil reservoir and extracting solution, it is recrystallized in isobutyl isobutyrate (IBIB) solution, dehydrating agent is dehydrated, obtain finished product valeric acid. |
