Density: 0.894 g/mL at 25 °C
Flash Point: 8.9 °C
Enthalpy of Vaporization: 38.56 kJ/mol
Boiling Point: 72.6 °C at 760 mmHg
Vapour Pressure: 82.8 mmHg at 25 °C
Storage temp.: Flammables area
Sensitive: Moisture Sensitive
Appearance: light yellow to tan powder.
Canonical SMILES: CC[O-].[K+]
InChI: InChI=1S/C2H5O.K/c1-2-3;/h2H2,1H3;/q-1;+1
InChIKey: RPDAUEIUDPHABB-UHFFFAOYSA-N
Classification Code: TSCA Flag P [A commenced PMN (Premanufacture Notice) substance]
Stability: Stable, but highly flammable. Reacts violently with water. Contact with damp air may lead to heating of the solid, which could in turn ignite it, or materials with which it is in contact. Incompatible with air, water, moisture, acids, acid chlorides, acid anhydrides, oxidizing agents, reducing agents.

Potassium ethylate Uses

Potassium ethanolate (CAS NO. 917-58-8) is used in pharmaceutical raw materials and raw materials for organic synthesis.

Potassium ethylate Safety Profile

May ignite in moist air. Reacts with H₂O to form EtOH and KOH. When heated to decomposition it emits flammable and toxic fumes of H₂ and C₂H₄.
