| abstract | PROBLEM TO BE SOLVED: To regenerate a plasticizer from an acid anhydride and an alcohol component which are recovered as a secondary component when a waste plastic containing a plasticizer is thermally decomposed. A waste plastic made of vinyl chloride containing a plasticizer is decomposed at about 350 ° C. in a screw type extruder 2. The gas generated from the screw type extruder 2 is the first gas. It is condensed at 130 to 180 ° C. in the condenser 3 and recovered as an oil. Further, the hydrogen chloride gas portion of the generated gas is absorbed by water in the absorption tower 8 and recovered as hydrochloric acid. Next, the oily substance and the hydrochloric acid are mixed in the hydrochloric acid mixer 4, and the acid anhydride and the alcohol component in the oily substance undergo an esterification reaction to regenerate the plasticizer. |
