Physical Properties of the Nitroalkanes

Figuro 17.1 Hansen solubility parameters of four nitroalkanes in terms of their polarity and hydrogen bonding character. For comparison purposes, the average values of the acetate ester solvents, ketone solvents, and alcohols are included. 

The first set of entries in Table 17.2 are sorted in ascending order for the column containing resin number one, cellulose nitrate resin. All four nitroalkanes and another solvent, N-methyl 2-pyrrolidone, gave JR values in the range of 4.5-7.9 and thus are expected to be fairly good solvents for cellulose nitrate resin. The solvents listed as having JR values of greater than 10 are expected to be poor solvents for cellulose nitrate. The second set of
