WebApr 5, 2024 · The boiling point of acetone is 56 0 Celsius at room temperature. By definition, any liquid with a flashpoint less than 100F is considered to be a flammable liquid. ... Methanal is a gas (boiling point -21C), and ethanal has a boiling point of +21C. Acetone is produced directly or indirectly from propylene. Babies and children have a … WebMethanal, also known as formaldehyde, (HCHO) is a gas at room temperature (boiling point -21°C), and ethanal, also known as acetaldehyde, has a boiling point of +21°C. That means that ethanal boils at close to room temperature. Larger aldehydes and the ketones are liquids, with boiling points rising as the molecules get bigger. date and time formats c#
