99% Purity Monosodium Glutamate Nrog Cas 32221-81-1
Monosodium glutamate yog dawb prismatic siv lead ua los yog crystalline hmoov, tsw tsw, nrog tshwj xeeb nqaij tsw.Tus txheeb ze ntom ntom yog 1.635, lub melting point yog 195 ℃, thiab cov filling tshwj xeeb ntim yog 1.20.Nws yooj yim soluble hauv dej, thiab pH ntawm 5% aqueous tov yog 6.7-7.2.Nws yog qhov nyuaj rau yaj hauv ethanol thiab ether.Yog tsis muaj kev nqus dej noo, cov dej siv lead ua pib poob ntawm 120 ℃, thiab lub cev qhuav dej ntawm intramolecular pib ntawm 150-160 ℃ los ua sodium pyroglutamine, uas poob nws cov saj tshiab.Nws pib decompose rau hauv pyrrole ntawm txog 270 ℃.
