Description
a)フェノールとアセトンを一緒に混合し、
b)フェノールとアセトンを含有する混合物を48〜54℃の範囲の温度となし、次いで、
c)この温度でフェノールとアセトンを含有する混合物を触媒としての酸性イオン交換体と接触させ、
d)フェノールとアセトンを含有する混合物を反応させてビスフェノールAを生成する、
ことを含む方法に関する。
工程c)での酸性イオン交換体は、好適には共触媒と組み合わせて用いられる。
アセトン4重量%、異性体6重量%、ビスフェノールA7重量%、水0.05重量%、メルカプトプロピオン酸300ppm及び残りのフェノール(約83重量%)から構成される反応溶液を、100m3の、フェノールで湿らせた酸性イオン交換体 Lewatit SC104 を充填した反応器中、最上部から最下部まで、処理量30t/時で通過させる。これは、4.2t/時のビスフェノールAの製造に相当する。反応器入口温度は52℃に調節する。反応器出口温度は75℃である。この設定では、排出された母液の部分流は、量的に、部分流中に含まれるフェノール以外の全成分を考慮した、製造されたビスフェノールAの量を基準にして、5.1重量%となる。インダン、スピロビスインダン及びインデノールの含有量は、この操作方法を用いる反応器排出において、全部で12g/Lである。
ここで反応器入口温度が56℃及び反応器出口温度が79℃であること以外は、実施例と同様にして、試験を行う。この設定では、排出された母液の部分流は、量的に、部分流中に含まれるフェノール以外の全成分を考慮した、製造されたビスフェノールAの量を基準にして、8重量%となる。インダン、スピロビスインダン及びインデノールの含有量は、この操作方法を用いる反応器排出において、全部で19g/Lである。
