2 Compounds of Low Boiling Point Containing up to Four Si Atoms 

Separation of the volatile compounds was achieved using gas chromatography (Fig. 4). The structural formulae of the numbered compounds are shown in Table 7, together with their percentage contribution to the total product mixture (Tables 5 and 6). 

An inspection of the compounds in Table 7 shows that they contain only a few basic structures. The valencies of silicon which are not fixed in the carbosilane mole- 

Considerably more difficulties were encountered in overcoming the problem of separation and identification of the compounds of high molecular weight. Eventually, such product mixtures could be separated at least into groups of compounds by co- 

The compounds isolated as described here generally form colorless crystals which remain unharmed on sublimation. They are only slightly soluble in pentane, benzene or CCI4, but slightly more soluble in toluene. The solubility decreases as the molecular weight of the compounds increases.
