CE ÎNSEAMNĂ DIAZONIUM SALT ÎN ENGLEZĂ?
Compus de diazoniu
Compușii diazoniu sau sărurile de diazoniu sunt un grup de compuși organici care împart o grupare funcțională comună R-N2 + X- în care R poate fi orice reziduu organic cum ar fi alchil sau arii și X este un anion anorganic sau organic cum ar fi un halogen. Sărurile de diazoniu, în special cele în care R este o grupare arii, sunt intermediari importanți în sinteza organică a coloranților azo.
Definiția diazonium salt în dicționarul Engleză
Definiția sării de diazoniu din dicționar este oricare dintre o clasă de compuși cu formula generală ArN: N-M +, în care Ar este o grupare arii și M este un atom de metal; realizată prin acțiunea acidului azotic pe amine aromatice și utilizată în vopsire.
