Abstract

PURPOSE: The heterogeneous reaction between solid melamine and solid cyanuric acid is conducted in the presence of a specific amount of water to prepare in industrial scale title compound used as a flame retarder for polyamide in high efficiency.
CONSTITUTION: A mixture of solid melamine of formula I and solid cyanuric acid of formula II is mixed with 20-2000 parts by wt, per 100 parts of the mixture, of water and stirred or kneaded in a cylindrical mixer, a twine arm kneader to react them, thereby affording melamine cyanurate. The weight ratio of melamine to cyanuric acid is controlled in the range form 1:9 to 9:1. The reaction temperature is 0-250°C and time is 5 min-5 hr. The resulting product is dried and crushed to powders.
EFFECT: As the amount of water added is little, the filtration process requiring long periods of time can be omitted and the drying process can be performed easily
