The synthesis of 2,4,6-tris(di-tetrahydrofurfuroxy)phosphinyl-s-triazine (2) was achieved by the reaction of cyanuric chloride with tris(tetrahydrofurfuryl)-phosphite (1) or with sodium bis(tetrahydrofurfuryl)phosphite (5). 2 on treatment with anhydrous ammonia yielded ammonium salt of 2,4-diamino-6-tetrahydro-furfuroxy-phosphinyl-s-striazine (3), which on methylolation yielded (4). The reaction of 2 and 4 with cellulose powder under different experimental conditions was carried out and they were found to exhibit promising fire-retardant properties.
