PROCESS FOR THE PREPARATION OF COMPOUNDS CONTAINING ISOCYANURATE GROUPS BY THE CATALYTIC CYCLOTRIMERISATION OF ISOCYANATES WITH THE AID OF COMPOUNDS AMINOSILYL GROUPS

摘要

Compds. contg. aminosilyl gps. catalyze the cyclotrimerization of mono- and polyisocyanates to give isocyanurate ring-contg. compds.. Thus, a mixt. of 39.6 BuNCO and 4.7g Me2NSiMe3 was heated at 100-110C for 14hr to give 20.8g tributyl isocyanurate.
