| Physical and Chemical Properties | Property 2-octyne molecular formula CH3(CH2)4C≡ C- CH3, one of acetylene derivatives, colorless liquid. The relative density of 2-octyne is 0.7596, the melting point is -61.6 ℃, and the boiling point is 138 ℃. It can be made by the interaction of sodium propyne and n-amyl chloride. 2-octyne is insoluble in water, soluble in alcohol, ether density relative density (water = 1)0.76. 2-Octyne is a medium flash point liquid. When exposed to heat, open flame, the oxidant is in danger of causing combustion and explosion. 2-octyne can be used as an intermediate in organic synthesis and chemical medicine synthesis, mainly used in laboratory research and development process and chemical medicine synthesis process. |
| Use | Overview acetylene compounds are particularly useful as intermediates in the synthesis of agricultural chemicals and drugs and as monomers that can be converted into high strength polymers by cross-linking, and there is no variation in the chain structure of the molecule or no production of moisture and other gases. For example, a method of reacting an acetylene compound with other compounds. As a method which is also commonly used, the Japanese patent discloses a method of obtaining an acetylene derivative by halogenating a compound having a double bond once and then dehydrohalogenating it. Further, a method of heating a compound having two or more hydrogen atoms on the carbon atom at the α-position of the carbonyl group at 600 ° C. In the presence of a vanadium catalyst is disclosed. |
