SODIUM SACCHARIN
Kev Taw Qhia
Sodium saccharin tseem hu ua saccharin, thiab nws lub npe scientific yog phthaloxylphenylimide sodium ntsev. Cov siv lead ua dawb prism. Qhov hnyav molecular 205.17. Melting point 226 ~ 231 ℃. Tsis muaj ntxhiab lossis me ntsis tsw qab, qab zib heev thiab iab, maj mam hloov pauv hauv huab cua, poob li ib nrab ntawm cov dej crystalline thiab ua hmoov dawb. Qhov qab zib ntawm cov tshuaj dilute yog li 300 txog 500 npaug ntawm cov suab thaj, thiab qhov qab zib threshold Chemicalbook tus nqi yog li 0.00048%. Nws yooj yim soluble hauv dej thiab me ntsis soluble hauv ethanol. Nws qhov thermal stability hauv cov kua dej zoo dua li ntawm saccharin, thiab nws tsis hloov pauv thaum cua sov ntawm 100 ℃ rau 2 teev. Cov kua dej tso rau lub sijhawm ntev, thiab qhov qab zib maj mam txo qis. Nws feem ntau yog siv ua cov khoom qab zib noj tau. Nws tsis lwj hauv tib neeg lub cev, tawm hauv zis, thiab tsis muaj txiaj ntsig zoo rau kev noj haus. Nws yog ua los ntawm phthalic anhydride lossis toluene.
Cov khoom siv tshuaj lom neeg
Pob zeb diamond dawb siv lead ua los yog hmoov crystalline, tsis muaj ntxhiab, Muaj cov roj tsw qab me ntsis, qab zib heev, thiab qhov saj tom qab yog me ntsis iab, uas yog 300-500 npaug qab zib dua li ntawm sucrose. Melting point 226-Chemicalbook231 ℃. Yooj yim soluble hauv dej (99.8g, 20 ℃; 186.8g, 50 ℃; 328.3g, 95 ℃), soluble hauv ethanol (1g / 50mL).
SIV
Sodium saccharin yog ib yam khoom qab zib uas siv los ntawm cov khoom siv dag. Nws tsis nqus tau rau hauv tib neeg lub cev thiab tsis tsim cua sov. Nws siv tau rau txiv plum thiab Chenpi, qhov siab tshaj plaws yog 5.0g / kg, thiab qhov siab tshaj plaws hauv cov noob txiv lws suav yog 1.2g / kChemicalbookg; qhov siab tshaj plaws hauv cov dej haus, ua cawv, ice cream, ice cream, popsicles, pickles, compound seasonings, txiv hmab txiv ntoo candied, pastries, biscuits thiab mov ci yog 0.15 G / kg; ntxiv cov kua txiv concentrated ntawm 80% ntawm cov concentrated multiple.
