| titleOfInvention | A METHOD FOR THE SEPARATION AND RECOVERY OF ISOPRENE FROM A REACTION MIXTURE OF ISOBUTILENE AND FORMALDEHYDE. |
| abstract | A method of separating and recovering isoprene from a reaction mixture of isobutylene and formaldehyde, comprising allowing a reaction mixture of isobutylene and formaldehyde to come into contact with water to remove formaldehyde; then, allow the resulting mixture to contact an oily substance, which is a by-product formed in the reaction between isobutylene and formaldehyde, in a distillation column under conditions such that the top of the distillation column is maintained at a temperature of not more than approximately 50ºC and the bottom thereof is maintained at a temperature of not less than approximately 80ºC, and lastly, the material removed from the bottom of the column is subjected to distillation, thereby recovering isoprene as distillate.
