99% Purity Monosodium Glutamate Nrog Cas 32221-81-1
Monosodium glutamate yog cov siv lead ua dawb prismatic los yog crystalline hmoov, tsis muaj ntxhiab, nrog rau cov nqaij tshwj xeeb saj. Qhov ceev ntawm qhov sib piv yog 1.635, qhov melting point yog 195 ℃, thiab qhov ntim tshwj xeeb yog 1.20. Nws yooj yim yaj hauv dej, thiab pH ntawm 5% aqueous kua yog 6.7-7.2. Nws nyuaj rau yaj hauv ethanol thiab ether. Yog tsis muaj dej noo nqus, cov dej siv lead ua pib ploj ntawm 120 ℃, thiab qhov intramolecular dehydration pib ntawm 150-160 ℃ los tsim sodium pyroglutamine, uas poob nws cov saj tshiab. Nws pib decompose rau hauv pyrrole ntawm li 270 ℃.
