Embodiment 1
[0076] The present embodiment provides a kind of polymerization method of carbon monoxide, comprising:
[0077] Step S1, packing metal lithium powder and liquid carbon monoxide into a high-pressure chamber, and then sealing the high-pressure chamber; wherein, the volume ratio of metal lithium powder to liquid carbon monoxide is 3:100.
[0078] Step S2, pressurizing the high-pressure chamber to 5GPa and maintaining it for 10 minutes to prepare polymerized carbon monoxide.
[0079] In step S2, the Raman spectrum detection is used to monitor the state transition process of the sample inside it, such as figure 1 As shown, the carbon monoxide encapsulated in the diamond anvil device by the low-temperature liquefaction method has an ambient pressure of about 0.8GPa. At this time, it can be clearly seen that the carbon-oxygen triple bond is located at 2100cm through the Raman spectrum. -1 The Raman peak near the wave number indicates that carbon monoxide is in a molecular state at t...
Embodiment 2
[0081] The present embodiment provides a kind of polymerization method of carbon monoxide, comprising:
[0082] Step S1, packing metal lithium powder and liquid carbon monoxide into a high-pressure chamber, and then sealing the high-pressure chamber; wherein, the volume ratio of metal lithium powder to liquid carbon monoxide is 8:100.
[0083] Step S2, pressurizing the high-pressure chamber to 4GPa and maintaining it for 8 minutes to prepare polymerized carbon monoxide.
[0084] In step S2, Raman spectroscopy is used to monitor the state transition process of the internal sample, and it is found that under 4GPa, the carbon-oxygen triple bond of carbon monoxide is broken, and the opened carbon atom is connected with the adjacent carbon atom to form a carbon chain. at 1500-1600cm -1 Raman peaks of carbon-carbon near the wavenumber. It can be seen that under 4GPa, the polymerization reaction of carbon monoxide is completed.
Embodiment 3
[0086] The present embodiment provides a kind of polymerization method of carbon monoxide, comprising:
[0087] Step S1, packing metal lithium powder and liquid carbon monoxide into a high-pressure chamber, and then sealing the high-pressure chamber; wherein, the volume ratio of metal lithium powder to liquid carbon monoxide is 15:100.
[0088] Step S2, pressurizing the high-pressure chamber to 3GPa and maintaining it for 5 minutes to prepare polymerized carbon monoxide.
[0089]In step S2, Raman spectroscopy was used to monitor the state transition process of the internal sample, and it was found that under 3GPa, the carbon-oxygen triple bond of carbon monoxide was broken, and the opened carbon atom connected with the adjacent carbon atom to form a carbon chain. At this time, at 1500-1600cm -1 Raman peaks of carbon-carbon near the wavenumber. It can be seen that under 3GPa, the polymerization reaction of carbon monoxide is completed.
