| titleOfInvention | Method for producing glycolide, which is provided with rectification step by means of gas-liquid countercurrent contact, and method for purifying crude glycolide |
| abstract | Step (1) A step of feeding a GAO composition containing a high-boiling organic solvent or a solubilizing agent to a reaction vessel and heating to a temperature at which the depolymerization reaction of GAO occurs. Step (2) Heating is continued to cause GAO to be depolymerized (4) a step of introducing an effluent into a rectifier, rectifying the GL by countercurrent contact with gas, and (5) a step of recovering the GL from the GL recovery step A method for producing GL; (I) a step of supplying a crude GL composition containing a high boiling point organic solvent or a solubilizing agent to a reaction vessel and heating the resulting GL to flow out, (ii) introducing the effluent into a rectifier, (Iii) a process for purifying crude GL having a GL recovery process; A GL production apparatus having a reaction vessel and a rectifier, and a crude GL purification apparatus. |
