Summary

Dispersions of a few different tars, viz. horizontal retort, vertical retort, coke-oven and producer-gas tars, in nitrobenzene were examined with the help of electronmicroscope. The colloidal micelles in each were found to be different in size and, in some cases, shape as well. An attempt has been made to explain the difference in binding properties, that is, their binding power for road aggregates and coke breeze or coal slurry for briquettes, by studying the micelle structure of the different tars.

Zusammenfassung

Dispersionen von verschiedensten Teeren in Nitrobenzol wurden elektronenmikroskopisch untersucht. Es ergaben sich Mizellen verschiedenster Größen und in einigen Fällen auch von verschiedener Form. Es wurde versucht, Zusammenhänge dieser unterschiedlichen mizellaren Struktur der Teere mit ihrem für die Anwendungen wichtigen Bindevermögen zu erschließen.
