On the basis of this finding, a two-step (stepwise) development technique12 was applied to separations of possible three binary mixtures of polybutadienes with different chain microstructure, namely, those of cis-1,4 + tram-1,4, tram-1,4+1,2-1,2-vinyl, and 1,2-vinyl + cis-1,4. The principle consisted of a utilization of the different development characteristics exhibited by carbon tetrachloride and amyl chloride. An example of this procedure applied by these authors83 will be described below. A mixture cis-1,4 + tram-1,4 was developed primarily with amyl chloride until the solvent front reached a distance, e.g., 10 cm from the starting point by this development only the cis-1,4 polymer should have migrated up to the solvent front (cf. Table 4). In order to identify the immobile component, the chromatogram was dried in vacuum at room temperature and treated with carbon tetrachloride until the solvent front reached an intermediate distance, e.g., 5 cm. It is obvious that this procedure can be alternatively used for identification of any unknown binary mix-... 

The amyl alcohol and sodium nitrite are mixed in a flask (500 C.C.), and whilst the mixture is cooled in ice-water, the cone, sulphuric with constant shaking. Towards the end of the process a more vigorous reaction sets in, when care must be taken to add the sulphuric acid more slowly. When the whole of the acid has been added, the top layer of amyl nitrite is decanted into a separating-funnel. A little water is then added to the residue and, after shaking, a further quantity of amyl nitrite separates and is decanted as before. The whole of the amyl nitrite is then separated from water, dehydrated over calcium chloride and distilled. The liquid boiling at 95—100° is collected separately. Yield, 30—35 grams. 

Equal vols. of amyl alcohol containing 1% (v/v) di-2-ethyl hexyl phosphate and 0.5% sodium chloride in borate buffer (0.62 g boric acid, 0.21 g borax) are mixed. Adjust pH to 8.0 with sodium hydroxide while stirring for 30 min. Separate phases dip paper in lower phase, blot, apply samples and dry several minutes. While still wet develop with organic phase either ascending or descending Detection...
