Abstract

Oppfinnelsen vedrører en ny fremgangsmåte for fremstilling av MEL-type titansilikalitt, det oppnådde produkt og dets forskjellige anvendelser på området katalyse. Fremgangsmåten ifølge oppfinnelsen for fremstilling av MEL-type titan- silikalitt kjennetegnes ved at den består i: impregnering av en amorf xerogel (Ti02-Si02) omfattende minst elementene silisium og titan med en oppløsning omfattende minst ett strukturmiddel og minst ett mobiliseringsmiddel OH", idet impregneringsopplzsningen omfatter minst en effektiv mengde av en forbindelse av typen 3,5-dimetylpiperidinium anvendt som strukturmiddel, oppvarming av reaksjonsblandingen opp til krystalliseringstemperaturen for zeolitten, deretter utvinning og kalsinering av den oppnådde zeolitt. De oppnådde zeolittkrystaller fremviser en morfologi som resulterer fra deres fremstillingsmetode.The invention relates to a novel process for the preparation of MEL-type titanium silicalite, the product obtained and its various applications in the field of catalysis. The process of the invention for the preparation of MEL-type titanium silicalite is characterized in that it consists in: impregnating an amorphous xerogel (TiO2-SiO2) comprising at least the elements silicon and titanium having a solution comprising at least one structural agent and at least one mobilizing agent OH the impregnating solution comprises at least an effective amount of a compound of the type 3,5-dimethylpiperidinium used as a structural agent, heating the reaction mixture up to the crystallization temperature of the zeolite, then recovering and calcining the obtained zeolite.
