“…In his recent book on industrial solvents, Mellan (7) lists the following factors as those which influence the rate of evaporation of a solvent from a solution: (1) Temperature of the substance, (2) temperature of the surrounding area, (3) rate of external heat applied, (4) conductivity of heat, (5) specific heat of the substance, (6) latent heat of evaporation, (7) number and type of molecular aggregates, (8) surface tension, (9) presence of dissolved substances, (10) atmospheric pressure, (11) presence of water vapor (humidity), (12) vapor pressure or pressures of the substance or substances under consideration, (13) amount and rate of temperature depression, (14) molecular weight of the substance, (15) method and speed of removal of vapors, (16) depression of vapor pressure, and (17) viscosity.…”

“…Most of this work has been done on pure solvents, and there have been very nearly as many different types of apparatus employed as there have been investigators. Each new development has been in a sense a refinement of older methods in an attempt to obtain an easier operation and a greater reproducibility of results (.1, 5,6,8,10,11,12).…”

Samples of the solvent-diluent mixture were used to make up nitrocellulose and nitrocellulose resin solutions. The composition of the solutions was determined at various stages of evaporation (from 0-95 per cent). The data indicated the following relations between mixtures containing no nonvolatile material and mixtures containing nonvolatile material such as nitrocellulose or resin: (1) During the first 50 per cent of evaporation the composition of the solvent-diluent mixture was apparently unaffected by the nonvolatile material. (2) I n the last 5 per cent of unevaporated liquid mixture apparently no hydrocarbons were present. (3) Apparently in solvent-diluent mixtures containing only nitrocellulose as the nonvolatile material, the last few per cent of hydrocarbons evaporate at a relatively slower rate.(4) If ester gum was also present, butyl alcohol was held back more than the last few per cent of hydrocarbons. Apparently the ingredient held back least by the nonvolatile material was butylacetate.N PREVIOUS work on solvent balance, the effect of nonvolatile material was not studied ( 1 , 3 , 8,9). The object of this paper, therefore, was to outline some of the possible effects of solid material. The types and concentrations of the nonvolatile material were chosen so that there would be at least a rough correlation between the data obtained and previous data of the authors (9). These are shown in Table I. Doolittle (4) showed the importance of knowing the ester content of ester solvents. For the present work butyl ace-
