| abstract |
The invention relates to a simple, one-step process for the preparation of triazines of formula ##STR1## which comprises reacting the benzonitrile of formula (I) ##STR2## with the benzonitrile of formula (II) ##STR3## in the temperature range from 180° to 260° C., in which formulae above R 1 and R 2 are as defined in claim 1. n The compounds prepared by this process find utility as UV absorbers or as starting materials for the preparation of UV absorbers. |
