verendeten Teerarten brüchig werden und dadurch die Anforderungen, die an ein Bindemittel gestellt werden, nicht erfüllen. Die Erfindung beruht nun auf der Erkenntnis, dass die Neigung zu Brüchen darauf zurückzuführen ist, dass die Teermasse Naphtalin enthält, welches ein stark kristallinisches Gefüge der Teermasse mit sich bringt. Die Erfindung beruht ferner auf der Erkenntnis, dass das im Teer enthaltene Phenol bzw. Kreosot sehädliche Einwirkungen auf Pflanzen und Tiere ausübt und sich als zähe schmierige Masse auf allen Gegenständen niederschlägt.
Wird dem Teer Naphtalin und Kreosot entzogen, so eignet er sich z. B. nicht mehr für die Zwecke der

Diese Übelstände werden der Erfindung gemäss dadurch behoben, dass die Teermasse vorerst teilweise destilliert und derselben Naphtalin und zweckmässig auch Phenol bzw. Kreosot entzogen wird und der so gewonnenen erhitzten Teermasse wenn nötig Öle zugesetzt werden, die eine

Process for the production of a binding agent from tar.
EMI1.1
Dead tar types become brittle and therefore do not meet the requirements placed on a binding agent. The invention is based on the knowledge that the tendency to fracture is due to the fact that the tar mass contains naphthalene, which brings about a strongly crystalline structure of the tar mass. The invention is further based on the knowledge that the phenol or creosote contained in the tar has harmful effects on plants and animals and is deposited as a viscous, greasy mass on all objects.
If naphthalene and creosote are removed from the tar, it is suitable for B. no longer for the purposes of
EMI1.2
According to the invention, these inconveniences are remedied in that the tar mass is initially partially distilled and naphthalene and expediently phenol or creosote is removed from it and, if necessary, oils are added to the heated tar mass obtained in this way
