P-06　PVCの低温熱分解中における炭酸カリウム, 炭酸カルシウムおよび酸化カルシウムによるHClの捕捉に関する研究

抄録

It was found that by adding CaO or K₂CO₃ to PVC at a molar ratio of 3 during pyrolysis at 573K, the hydrogen chloride generation rate could be reduced from 75% to 20%. On the other hand, when CaCO₃ was added at the same molar ratio, the hydrogen chloride generation rate could only be reduced to about 60%. Further, when K₂CO₃ was added at a molar ratio of 1, the amount of hydrogen chloride contained in the solid residue was about 50%.
