Sulfoisophthalic Acid Monosodium Gishiri CAS 6362-79-4
Gishirin monosodium na sinadarin Sulfoisophthalic acid (CAS 6362-79-4, sunan Ingilishi: 5-sulfoisophthalic acid monosodium (gishiri) muhimmin sinadari ne na halitta, wanda ya samo asali daga sinadarin sulfonated modified aromatic dicarboxylic acid. Tsarin kwayoyin halittarsa ya dogara ne akan isophthalic acid a matsayin rukuni na iyaye, tare da rukunin sulfonic acid (-SO₃H) wanda aka gabatar a matsayi na 5 na zoben benzene kuma ya samar da gishiri tare da sodium.
Daga mahangar halayen jiki da sinadarai, gishirin monosodium na 5-Sulfoisophthalic acid yawanci yana bayyana a matsayin farin foda, tare da wurin narkewa na 373℃. A 20℃, yawansa shine 1.87, kuma yana da kyakkyawan narkewar ruwa (380g/L). A 20℃, ƙimar acidity (pKa) shine 4.1, kuma a 23℃, LogP ɗinsa shine -1.7. Gabaɗaya. Sodium m-5-sulfonate yana da karko a yanayi kuma yana narkewa cikin ruwa cikin sauƙi, wanda hakan ya sa ya dace da yanayin amfani da tsarin da aka dogara da ruwa.
