Abstract

Mevcut buluş, metakrolein üretimine yönelik olarak bir yöntemdeki su içeriğinin düzenlenmesi ile ilgilidir. Metakrolein, özellikle metakrilik asit, metil metakrilat veya aktif, koku veya tat verici maddelerin üretimine yönelik bir ara ürün olarak kimyasal sentez içerisinde kullanılır. Özellikle, mevcut buluş, bir Mannich yoğunlaştırması vasıtasıyla, metakroleinin formaldehit ve propionaldehitten üretimine yönelik olarak bir yöntemde su içeriğinin düzenlenmesi ile ilgilidir.
