17-octadecynoic acid - Introduction
17-octadecynoic acid(17-octadecynoic acid) is an organic compound with the chemical formula C18H32O2. It is a colorless to light yellow oily liquid with special chemical properties and applications.
Nature:
17-octadecynoic acid is a long-chain acetylenic acid with low solubility and relatively high melting point. It is a solid state at normal temperature, but can become a liquid after heating. It has a melting point of about 82-84 degrees Celsius and a boiling point of about 180 degrees Celsius. This compound has a strong pungent odor.
Use:
17-octadecynoic acid has a variety of uses in chemical experiments and research. It can be used as a lipid polymer monomer for the preparation of various functional oils and lipid polymers. In addition, it is also widely used in the functional modification of natural and synthetic macromolecular compounds, including the study of cell membrane permeability and pore structure.
Preparation Method:
17-octadecynoic acid can be prepared through a variety of synthetic routes, one of which is commonly used through the oxidation reaction of octadiynol, using an oxidizing agent such as chromium sulfate or sodium peroxodisulfate. This reaction leads to the formation of 17-oct-1-ynal, followed by hydrogenation and acidification to the final product, 17-octadecynoic acid.
Safety Information:
17-octadecynoic acid is considered relatively safe under normal conditions of use and storage. However, it is a surfactant, which is irritating and corrosive. In use, appropriate personal protective equipment should be used to avoid direct contact with skin and eyes, and to avoid inhalation of its vapors. During storage and handling, it should be properly kept away from ignition and oxidizing agents. If necessary, please read the safety data form of the relevant chemical for more detailed safety information.
