Abstract:The present paper investigates Raman spectral characters of 1-hexanol by the SiC anvil cell at the pressure of 163.4-793.4 MPa and the temperature of 25 ℃. It was found that under the pressure of 163.4-767.6 MPa the character of 1-Hexanol is steady, and the frequencies of C—H symmetrical stretch vibration and antisymmetric stretch vibration increase with increasing pressure, and the relations between the frequency and the pressure are given as follows: ν2 876=0.009 1P+2 875.1, ν2 931=0.005 7P+2 930.5. At 793.4 MPa there is transformation from liquid state to solid state. On the basis of former data, the authors contrasted the features of 1-hexanol, methanol and ethanol under high pressure. It was revealed that the relation between wave numbers of C—H symmetrical stretch vibration peaks and system pressure is independent of the C—C bond, that is the relation between wave numbers of C—H symmetrical stretch vibration peaks and system pressure is foreign to the number of the carbon atoms.
