TL;DR: In this paper, the viscosity data for the series of 1,2-alkanediols, H(CH2)n-2CH(OH)CH2(OH), for n = 3 to 6, 8, 10, and 12, were presented.
Abstract: This paper presents the viscosity data for the series of 1,2-alkanediols, H(CH2)n-2CH(OH)CH2(OH), for n = 3 to 6, 8, 10, and 12. The results are compared with those obtained for 1,n-alkanediols.

TL;DR: In this paper, the shear viscosity of isotropic liquids belonging to the homologous series of 4-(trans-4'-n-alkylcyclohexyl) isothiocyanatobenzenes was analyzed with the use of the Arrhenius equation and its two modifications.
Abstract: Temperature dependence of the shear viscosity measured for isotropic liquids belonging to the three homologous series: 4-(trans-4'-n-alkylcyclohexyl) isothiocyanatobenzenes (C n H 2 n + 1 CyHx Ph NCS; nCHBT, n = 0 + 12), n-alkylcyanobiphenyls (C n H 2 n + 1 Ph Ph CN; nCB, n = 2 + 12) and 1, n-alkanediols (HO(CH 2 ) n OH; 1,nAD, n = 2+10) were analysed with the use of Arrhenius equation and its two modifications: Vogel-Fulcher and proposed in this paper The extrapolation of the isothermal viscosity of 1, n-alkanediols (n = 2 + 10) to n = 1 leads to an interesting conclusion concerning the expected viscosity of methanediol, HOCH 2 OH, the compound strongly unstable in a pure state
