pendence to a certain degree. This behavior could be due to the lack of information of µ0, the gas phase viscosity data. RECOMMENDED VALUESRecommended values for viscosity of rc-decane for temperatures from 100°to 460°F. and pressures from 200 to 8000 p.s.i.a. are presented in Table I, in which experimental data are also presented in parentheses. The density values were those of Sage and Lacey (7). ACKNOWLEDGMENTThis investigation was part of a continued study of the physical and thermodynamic properties of hydrocarbons under the basic research program of the Institute of Gas Technology. The work was supported in part by IGT Members and Contributors and in part by the American Petroleum Institute through Project No.

The feasibility of a room-temperature, nonaqueous organic solvent, electrochemical cell that can deliver 10 mA/cm 2 at 4V has been demonstrated. The cell consists of a lithium negative, a graphite compound positive electrode, and a lithium perchlorate-dimethyl sulfite electrolyte solution. The cell develops an open-circuit potential of approximately 4.5V. Apparently the lithium perchlorate-dimethyl sulfite electrolyte undergoes no or least slow oxidation or reduction within a 4.5V range.To date, the maximum charge storage has been 90 coulombs/g of graphite. Cycles of 1 hr charge and 1 hr discharge at about 3 m-A/cm 2 have been repeated up to 33 times. Failure was apparently due to overcharging and graphite disintegration. On wet stand, from 25 to 50% of the cell capacity is lost over one day.
