⚗️ Chemical & Physical Properties
Propiolic Acid, also known as propynoic acid, is a colorless liquid with a sharp and pungent odor. It is typically described as having an acrid smell similar to acetic acid.
With a molar mass of 56.06 g/mol and a density of 1.08 g/cm³, Propiolic Acid is relatively light compared to common household items like water (molar mass: 18.02 g/mol, density: 1 g/cm³) and ethanol (molar mass: 46.07 g/mol, density: 0.789 g/cm³).
The melting point of Propiolic Acid is around -68°C, while its boiling point is approximately 146°C. Compared to common household items like ice (melting point: 0°C) and water (boiling point: 100°C), Propiolic Acid demonstrates a much lower melting point and a significantly higher boiling point.
Proprionic Acid is sparingly soluble in water and has a low viscosity. In comparison to common household items like sugar (soluble in water) and honey (high viscosity), Propiolic Acid exhibits similar solubility properties but a lower viscosity.
🏭 Production & Procurement
Propiolic acid, also known as propynoic acid, is primarily produced through the oxidation of propynyl alcohol. This process involves the use of oxidizing agents such as potassium permanganate or chromium trioxide to convert propynyl alcohol into propiolic acid.
To procure propiolic acid, one must generally purchase it from chemical suppliers who specialize in the production and distribution of organic acids. It is typically available in various purities and quantities, depending on the specific needs of the purchaser. Once procured, propiolic acid can be transported in sealed containers to prevent any accidental spills or leaks during transit.
When transporting propiolic acid, it is important to adhere to all relevant safety regulations and guidelines to ensure the proper handling and transportation of this corrosive and potentially hazardous substance. Suitable protective gear and equipment should be used by personnel involved in the transportation process to minimize the risk of exposure to propiolic acid. Additionally, proper labeling and packaging of containers are essential to prevent any accidents or incidents during transit.
