I-DAP 18-46-00
I-Diammonium phosphate, ekwabizwa ngokuba yi-diammonium hydrogen phosphate, i-diammonium phosphate, yikristale emhlophe engacacisiyo enemibala emhlophe okanye umgubo omhlophe. Ukuxinana kwesihlobo yi-1.619. Ngokulula inyibilika emanzini, inganyibiliki ngotywala, i-acetone, kunye ne-ammonia. Bola xa ushushu ubushushu ukuya kwi-155 ° C. Xa ivezwe emoyeni, ngokuthe ngcembe ilahlekelwa yi-ammonia kwaye iba yi-ammonium dihydrogen phosphate. Isisombululo samanzi sine-alkaline, kwaye ixabiso le-pH le-1% isisombululo ngu-8. Iyadibana ne-ammonia ukuvelisa i-triammonium phosphate.
Inkqubo yokuvelisa i-diammonium phosphate: Yenziwe sisenzo se-ammonia kunye ne-phosphoric acid.
Ukusetyenziswa kwe-diammonium phosphate: esetyenziswa njengendawo yokubamba umlilo kwizichumisi, iinkuni, iphepha, kunye namalaphu, ikwasetyenziswa nakwinyango, iswekile, izongezo zesondlo, igwele kunye neminye imiba.
Kancinci ilahleka i-ammonia emoyeni kwaye iba yi-ammonium dihydrogen phosphate. Isichumisi esisebenza ngamanzi esinyibilikayo sisetyenziswa kwimihlaba eyahlukeneyo nakwizityalo ezahlukeneyo. Ingasetyenziselwa isichumiso sembewu, isichumiso esisisiseko kunye nokunxiba okuphezulu. Musa ukuyixuba nezichumisi ezinjengealkali ezifana nomlotha wesityalo, ikalika i-nitrogen, ikalika, njalo njalo, ukuze unganciphisi ukusebenza kwesichumiso.
