CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishA new dry-sweating technique, based on the use of a centrifuge was applied to purify solid particles of E-caprolactam. It allows elimination of up to 80% of the organic impurities with a relatively low molten mass, between 20 and 30%. Experimental runs were carried out on specifically produced solid pastilles and solid particles of industrial material. On the basis of the achieved results, a mechanism of the dry-sweating process is proposed. (C) 2002 Elsevier Science B.V. All rights reserved.
