sodium formaldehyde sulfoxylate lump


1, nature:
Chemical name: sodium bisulfate formaldehyde
Molecular formula: NaHSO2 · CH2O · 2H2O
Molecular weight: 154.12
Weight: 1.8
Melting point: 64 ° C
Melting heat: 54.84KJ / mol (13.2KCal / mol)
Moisture point: 60% relative humidity
Stability point: less than 50 ºC
Solubility: 20 ºC, 1 carved white block, carved white powder, carved white particles need 1.2 copies of water dissolved (45%)
70 ºC, a carved white block, carved white powder, carved white tablets need 1 part of water dissolved (50%)
Physical properties: carved white block, carved white powder, carved white particles with a strong reducing salt, white condensed lumps or powder, granules, was alkaline protection.
Chemical properties:
A. Carved white block (powder, grain) easy to damp exotherm, 80 ºC began to decompose, the release of H2S, need to dry low temperature preservation.
6NaHSO2 · CH2O + 3H2O - → 4NaHSO3 + 2HCOONa + 2H2S + HCOOH + 3CH3OH
B. When the temperature rose to 110 ºC, carved white block (powder, grain) decomposition, the molecules of formaldehyde split release new [H], the strongest reduction force.
NaHSO2 · CH2O - → NaHSO2 + CH2O
NaHSO2 + H2O - → NaHSO2 + 2 [H]
C. Carved white block (powder, grain) is divided into oxidants, such as with the I2.
NaHSO2 · CH2O + 2H2O + 2I2- → NaHSO4 + 4HI + CH2O
D. Carved white block (powder, grain) should be in alkaline medium PH> 8, acid (acid limit PH> 3) can make carved white block decomposition of hydrogen sulfide.
