Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 51 N° 51 (Décembre 2012) . - pp. 16531–16536 Titre : Kinetic model of melamine phosphate precipitation Type de document : texte imprimé Auteurs : Barbara Cichy, Auteur ; Ewa Kuzdzal, Auteur Année de publication : 2012 Article en page(s) : pp. 16531–16536 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Kinetic Phosphate Résumé : The kinetics of the melamine phosphate precipitation reaction under stable mixing conditions and at constant temperature were described along with the morphology of the crystals obtained. The kinetics of the reaction between melamine and phosphoric acid was described using a model of crystallization which included a stage of rapid dissolution of solid melamine dispersed in water in phosphoric acid, followed by nucleation and growth of sparingly soluble crystals of melamine phosphate. Experimental results have confirmed the assumptions made. The size and shape of the obtained melamine phosphate particles is important for the size and shape of the product of the second reaction—melamine polyphosphate. This allows for a certain scope of control over the process of shaping the particles of plastics filler—melamine polyphosphate.
