Abstract
Inventia se refera la un procedeu pentru obtinerea amidelor prin hidratarea continua a nitrililor în prezenta unor catalizatori metalici suspendati în mediul de reactie variind între 1....50% de preferinta 5-15% si la un aparat constituit dintr-un vas cu manta în care este situat în centrul un filtru în care se afla un suport pentru catalizator prevazut cu santuri colectoare la întretaierea carora se afla orificiul de evacuare a solutiei de reacsie prevazut de asemenea cu tuburi de distributie cu orificii pentru spalarea tangentiala a filtrului.The invention relates to a process for the preparation of amides by the continuous hydration of nitriles in the presence of metal catalysts suspended in the reaction medium ranging between 1 ... 50%, preferably 5-15%, and on an apparatus comprising a jacketed vessel in which a filter is located in the center of which there is a catalyst support provided with collecting grooves at the intersection of which there is the outlet of the reaction solution provided also with distribution tubes with tangential washers of the filter.
