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 ℃.
