- Source not specified; purity not specified; purified.
- Not specified.
Estimated Errors:
Ambient temperature: ±0.2 K.
Components:
- Nitromethane, $\ce{ CH3NO2 }$; [75-52-5] NIST WebBook
- Water-d2, $\ce{ D2O }$; [7789-20-0] NIST WebBook

(a) LH and LD are the solubilities (in mole %) of nitromethane in H2O and nitromethane in D2O, respectively.
(b) This value refers to a temperature that corresponds to within ±0.5°C to the UCST of the nitromethane+water system. USCT is 105.5°C.
