Description
リン酸
リン酸の加水分解反応速度は、5%の高いリン酸レベルであっても、他の全ての酸と比較してはるかに遅かった。
MSAおよび硫酸の反応速度は両方ともリン酸よりも速かった。5重量%の硫酸では、反応は5分以内にほぼ平衡に達した。1重量%では、硫酸およびメタンスルホン酸の両方を使用した加水分解が約30分で平衡に達した。
pTSAを一水和物として使用した。同様のモル基準でpTSAのMSAとの加水分解速度を比較するために、2重量%pTSA溶液を使用した。MSAおよびpTSAの反応速度は類似しており、それぞれ約30分以内に平衡に達した。
MMAプロセスの不純物であるメタクリル酸を、加水分解触媒活性についてスクリーニングした。MAAは、メタノール回収塔に存在するが、典型的には非常に低レベルのみである。実証の目的ために、4%MAAを使用してMDA加水分解反応を実施した。MAAは、ここで研究した他の酸と比較して、ほぼ2倍遅い速度であるにもかかわらず、MDA加水分解を触媒した。
AMBERLYST-15(ドライ)IER樹脂を、この例のために使用した。Amberlyst-15≧4.7当量/kgに基づいて、ここで使用されるIERスルホン酸含有量は、2%pTSAの実験でその約4倍であった。5分間隔および30分間隔の両方でのAmberlyst-15触媒アセタール加水分解の速度は、1%硫酸を使用したものと同様であった。30分以内に平衡に達した。
追加の加水分解実験を上記のように実施したが、混合物中0.48%メタクリル酸ナトリウム(NaMAA)で実施した。0.2%MSAでは、2時間で検出可能な変換はなかった。AMBERLYST-15(ドライ)IER樹脂(20.07gの総混合物中0.41g)では、変換は2時間でわずか13%であった。塩なしの0.2%MSAを使用した対照実験は、5分間で99%の変換をもたらした。
