The polymorphism of alkali metal formates, part 2, A raman

When NaHCOO is heated, it undergoes a first- order transition from the room temperature phase NaHCOO-II to a high temperature phase NaHCOO-I at 500 K, Upon cooling NaHCO0-I, an intermediate phase NaHCO0-I’ was obtained, which was characterized by a Raman spectrum slightly different from that of the high temperature phase NaHCO0-I, Phase I

Sodium formate

Solid sodium formate is used as a non-corrosive agent at airports for de-icing of runways in mix with corrosion inhibitors and other additives, which rapidly penetrate solid snow and ice layers, detach them from the asphalt or concrete and melt the ice rapidly, Sodium formate was also used as a road deicer in the city of Ottawa from 1987 to 1988,

The effect of pressure on the Raman spectra of solids, III

The pressure dependence of the Raman bands of NaHCOO has been studied at 298 K and three different phases were identified up to pressures of 30 kbar, Phase II is the one stable at ambient conditions, and when heated to 500 K at ambient pressures it undergoes a transition to phase I, This transition has also been studied and the frequencies of the Raman‐active librations of NaHCOO I …
