b) 投与ポンプを用いて、5ml/分の速度で40gのp−キシレンを反応装置に装填した、
c) 10ml/分の速度で200gの酢酸を反応装置に装填した、
d) 1.0ml/分の速度で10gの触媒と促進剤の溶液[0.02質量%(溶媒に加え)のCo+2濃度、1/5のCo+2/Mn+2質量比、および1.0/1.0のBr-/(Co+2+Mn+2)比を有する]を反応装置に装填した、
e) 撹拌機をゆっくと始動させ、100〜150rpmに設定した、
f) 油浴からの熱油を循環させることによって、凝縮器の温度を85℃に設定した、
g) 50ml/時の流量で窒素を注入し、反応装置の圧力を1.8MPaに維持した、
h) 油浴からの熱油を循環させることによって、反応装置を215℃に加熱し、圧力調整バルブで1.8MPaの圧力を維持し、
i) 温度が215℃に到達した後、窒素ラインを閉じ、50ml/時の流量で空気を1.8MPaで注入し、
j) オンラインガス分析装置で排出ガス中のO2およびCO2濃度を検査し、[O2]が2.0〜2.5体積%の範囲にあり、[CO2]が1.3〜1.5体積%の範囲にあるように、空気の流量または温度を調節し、
k) 120分間に亘り反応を継続し、反応装置の温度を215〜220℃の間に、圧力を1.8〜1.9MPaの範囲に維持し(連続的に温度と圧力をモニタし)、
l) 温度を記録し、反応の発熱を調節し、反応温度が225℃より高くなったら気流を停止し、
m) 120分後、高温の油浴温度を低下させることによって、反応装置の20℃への冷却を開始し、
n) バルブを開くことによって、ガスをゆっくりと排気し、
o) 底のドレンバルブを開くことによって、スラリー生成物を取り出し、それをガラス製ビーカー内に収集し、
p) ブフナー漏斗を用いて濾過し、フード内で固体のCTE生成物および母液を分離し、
q) 2時間に亘りオーブン内において90℃で湿ったケーキを乾燥させ、
r) 生成物および母液を分析のためにサンプリングした。
実施例1について記載した様式を繰り返したが、Br-/Cs+のモル比が1になるような量で酢酸セシウムを添加した。回収したTPAについての結果が、表1に示されており、セシウムなどのアルカリ金属を添加すると、触媒性能がさらに改善され、例えば、望ましくない不純物のレベルが減少することを示している。
実施例1の実験を繰り返したが、ここでは、従来のCo系触媒を用い、促進剤として臭化マンガンを用いた。
