| titleOfInvention | Process of crotonaldehyde separation from mixture obtained through vapor-phase hydration of acetylene |
| abstract | 1. A METHOD FOR ISOLATING A CROTON ALDEHYDE FROM A MIXTURE RECEIVED DURING PARO PHASE HYDRATATION OF ACETYLENE by rectification in the first column at a temperature of cube 110-140 0 to obtain a bottoms residue, which is subjected to rectification in the second column at 120-140 ° C and isolate the desired product as distillate, characterized in that, in order to increase the degree of extraction of the target product, the distillation residue of the second column is subjected to rectification in the third column in the presence of acetaldehyde at a cube temperature of 120-150 ° C to obtain distillate, who sent the pot to 25-28 plate of the first column. 2. The method according to claim 1, about t l and h and y i and the fact that acetaldehyde is used in an amount of 5-15 wt.% From the cubic residue. (L with |
