Glycinamide Hydrochloride CAS 1668-10-6 (H-Gly-NH2 ·HCl) Mayeso 99.0~101.0% Factory High Quality

Malo osungunuka: Njira yodziwira capillary.Ayenera kukhala 200.0 ~ 205.0 ℃
Zitsanzozo zidadulidwa kukhala ufa wa pafupifupi 0.1g ndikuwumitsidwa mu uvuni woyaka pa 105 ℃ kwa theka la ola, kenako ndikukwezedwa mu chubu cha capillary ndikulongedza.Pamene kutentha kwa mafuta mu chida chosungunuka kukwera kufika ku 190 ℃, ikani capillary mmenemo ndikuwongolera kutentha kwa 3 ℃ pamphindi.Yang'anani poyambira kusungunuka kwa zomwe zili mu capillary ndikupitirizabe kutentha mpaka zonse zomwe zili mu capillary zisungunuke mpaka kusungunuka komaliza.
Zomwe zili: Titration ndi AgNO3
Yezerani chitsanzo cha 0.2000g, sungunulani m'madzi osungunuka ndikusungunula mpaka 100ml, onjezerani madontho 3-5 a potassium chromate chizindikiro, ndi titrate ndi 0.1000M muyezo wa siliva nitrate mpaka kumapeto.
Kuwerengera: Zomwe zili %=V×M÷G×0.1105×100
V- Volume yogwiritsidwa ntchito ndi muyezo wa silver nitrate titration mu ml
M- muyezo wa silver nitrate ndende mol/L
G- Yesani chitsanzo g
Muyezo wa chinyezi:
KF njira: Add 10ml anhydrous methanol mu mwatsatanetsatane chinyezi mita, titrate KF reagent ndi madzi ofanana 3mg/ml mpaka mapeto, mwamsanga chitsanzo 1.0000g, kuika pamwamba anhydrous methanol, titrate ndi KF reagent mpaka mapeto;Lembani voliyumu ya titration ml.
Kuwerengera: Chinyezi = V×N÷G×100÷1000
N--Madzi ofanana ndi KF reagent mg/ml
V--- Voliyumu yogwiritsidwa ntchito ndi KF reagent titration ml
G-- Wezani chitsanzo g
