Description
【請求項１３】 メラミン溶融物が、240℃とメラミンの凝固温度との間の温度を有するメラミン粉末に転化される請求項１１に記載の多結晶質メラミン粉末。
【請求項２３】 メラミン粉末が機械的に動かされ、かつ直接または間接に冷却されることによって、メラミン粉末が、少なくとも35℃に冷却される請求項１０〜２２のいずれか１項記載の多結晶質メラミン粉末。
【請求項２４】 メラミン粉末が機械的に動かされ、かつ直接または間接に冷却されることによって、メラミン粉末が、少なくとも60℃に冷却される請求項２３記載の多結晶質メラミン粉末。
出願人はここでまた、メラミン反応器から得られかつメラミンの融点〜450℃の温度を有するメラミン溶融物を、まず気体アンモニア（メラミン１モル当たり0.1〜15モルのアンモニア）で処理し、次いで噴霧手段によって噴霧し、アンモニア圧0.1〜25MPaのアンモニア環境中にある容器内で蒸発する冷却媒体によって冷却することによって、連続的に高純度でメラミンが製造できることを見出し、このメラミン溶融物は、200℃とメラミンの凝固点との間の温度を有するメラミン粉末へと転化され、該メラミン粉末は50℃より下の温度に冷却され、必要なら、他の冷却法がまた使用される。必要なら、この粉末は、同じ容器または別の容器中で、粉末を機械的に動かし、直接または間接に冷却することによって、さらに冷却されることができる。
