EFFECT OF PRESSURE ON THE STATIC RELATIVE PERMITTIVITIES OF 2-METHYL-1-ALKANOLS AT 298.15 K

Static relative permittivities, epsilon(r), were measured for 2-methyl -1-propanol, 2-methyl-1-butanol, 2-methyl-1-pentanol, and 2-methyl-1-h exanol under pressures up to 300 MPa at 298.15 K. Values of epsilon(r) increase with pressure for each 2-methyl-1-alkanol and are well-fitte d with the Tait-type equation. In addition, a good correlation equatio n of static relative permittivities, epsilon(r)(P, n), for 2-methyl-1- alkanols with pressure P and the number n in H(CH2)(n-2)CH(CH3)CH2OH ( n = 3 to 6) is given.
