Abstract

EPSの処理量を増やしていくと,反応フラスコ内の気相と液相の温度差は広がる傾向が見られ,大規模な処理量の下では反応温度の制御と共に,反応系内に残存する酸素の除去が重要であることが分かった.また,処理量の増大に伴い,EPSに対するMSDの最適な添加モル比は下がる傾向を示した.しかし,MSDの絶対重量は変わらず,EPSの処理量を増やしても,一定量が系内に存在すれば,熱分解を通してEPSの分子量を同程度にまで下げることができた.

The pyrolysis of expanded polystyrene (EPS) with 2, 4-diphenyl-4-methyl-1-pentene (MSD) as an additive was studied at a temperature about 200°C. In the time, the scale of EPS was increased in steps from 0.25g to 10g. We found that it was important to control the temperature in the reaction vessel because the temperature gradient of gas-phase and liquid-phase enlarged with an increase in the scale of EPS, and it was also necessary to remove the residual oxygen in the reaction vessel during the pyrolysis. The most efficient molar ratio of MSD to EPS decreased with an increase in the scale of EPS, but the absolute weight of MSD did not change.
