Solvent	Limiting viscosity number, dl/g	Slope of viscosity number versus concentration, (dl/g)2
1-chloronaphthalene 1,2,4-trichlorobenzene decahydronaphthaleneb	a0.890 ± 0.0032 1.010 ± .0086 1.180 ± .0032	0.48 .55 .72

^aUncertainties quoted are estimated standard deviations obtained from linear least squares fits of viscosity number versus concentration.

^bTechnical grade, which assayed at approximately equal proportions of cis- and trans-decahydronaphthalenes.
