Abstract

يتعلق الاختراع بطريقة مستمرة continuously operated method لإنتاج أيزوسيانات for producing isocyanates بتفاعل الأمينات المناظرة corresponding amines مع الفوسجين phosgene. عند تغيير سعة الإنتاج المستهدفة changing the target production capacity بدءاً من الحالة الأولية starting state بسعة إنتاج محددة with a specified production capacity والانتهاء بحالة نهائية end state بسعة إنتاجية مختلفة with a different production capacity، الفوسجين الفائض الحالي current excess phosgene بالفترة الانتقالية at the time of the transition period بين الحالة الأولية starting state والحالة النهائية end state ، التغيير بتدفق كتلة الأمينات the change of the amine mass flow يبدأ خلال الزمن المذكور said time ، على الأقل مساوياً لـ at least equal to ويفضل أن يكون أكبر من فائض الفوسجين greater than the excess phosgene خلال فترة الإنتاج production period عندما تكون السعة الإنتاجية production capacity بالحالة الأولية starting state قبل بدء الفترة الانتقالية transition period ؛ ومتوسط فائض الفوسجين average excess phosg
