APA TEGESÉ POLYPHOSPHORIC ACID ING BASA INGGRIS?
Asam fosfat lan fosfat
Ana macem-macem jinis asam fosfat lan fosfat. Saka akeh fosfor oxoacids, asam fosfat minangka klompok paling gedhe lan paling maneka warna. Seri asam fosfat paling gampang wiwit kanthi asam monophosphoric, terus karo asam oligofosphorat sing akèh kaya asam difhosphoric lan diakhiri ing asam polifosfat. Nanging, unit-unit asam fosfat bisa mbungkus bebarengan karo struktur cincin, sikil, utawa cabang cyclic, kanthi maneka warna kombinasi. Saben kasebut bisa mbentuk fosfat.
Definisi saka polyphosphoric acid ing bausastra Basa Inggris
Dhéfinisi asam polifosfat ing kamus kasebut arupa salah sawijining seri oxyacids saka fosfor kanthi rumus umum Hn + 2P nO3n + 1. Anggota pisanan yaiku asam pyrophosphoric lan seri kasebut kalebu asam metaphosphoric banget polimer. Asam sing luwih dhuwur ana ing campuran keseimbangn. Définisi lain asam polifosfatat minangka campuran ortofosor lan polifosfat asifat kaca utawa cair: digunakake kanthi industri minangka agen, katalis, lan oksidator dehidrasi.

Handbook of Detergents, Part F: Production
Commercial polyphosphoric acid ranges between 105 and 117%. The monoalkyl
to dialkyl ratio increases as the reaction temperature and the strength of the
polyphosphoric acid decrease, with the limit at pyrophosphoric acid [28].

Handbook of Polymer Synthesis: Part B (In Two Parts)
If polyphosphoric acid is used at 40°C, it is assumed that, in some cases, the poly
- benzimidazole is not completely cyclized [1 28]. In this respect, the conversion
of bis(o-diamines) with bisorthoesters in DMSO at 100°C is supposed to be more
