Abstract
يتعلق الاختراع الحالي بضبط محتوى الماء water content في عملية لإنتاج الميثاكرولين methacrolein. ويـُستخدم الميثاكرولين methacrolein في التصنيع الكيميائي وبالأخص كمركب وسيط لإنتاج حمض الميثاكريليك methacrylic acid، ميثاكريلات المثيل methyl methacrylate أو غيرها من المركبات الكيميائية الفعالة، العطرية أو المنكَّهة. ويتعلق الاختراع الحالي تحديداً بضبط محتوى الماء في عملية لإنتاج الميثاكرولين methacrolein من الفورمالدهيد formaldehyde والبروبيونالدهيد propionaldehyde عن طريق تكثيف مانيخ Mannich condensation. انظر الشكل 1
