Sinossi
Excerpt from Die Synthese des Kautschuks
Um welche gewaltigen Werte es sich hier handelt, geht daraus hervor, daß der jährliche Weltkonsum in Kautschuk, der im letzten Jahre 73000_t groß war, bei dem 2. Z. Geltenden Marktpreis von Mk. 12 bis 14 per Kilo eine Milliarde Mark beträgt; vor einem Jahre betrug der Ki10preis sogar Mk. 24. Dabei ist zu bemerken, daß das Produkt einer noch viel größeren Anwendung fähig ist. Im Vergleich dazu ist der Umsatz der Tecr farben-industrie Deutschlands mit etwa 500 Millionen Mark klein. In Zahlen ausgedrückt, kennt also die chemische Industrie kein größeres Problem. Aber das Wagnis ist hier außerordentlich groß, soll die Fabrikation in Konkurrenz mit der Natur aufgenommen werden; wissen wir doch, daß der Herstellungspreis des wilden Kautschuks zwar um Mk. 5. Herum, der jenige des plantagen-kautschuks aber, wie er in Java, Sumaha und Ceylon gewonnen wird, zwischen Mk. 2. Und 3. Beträgt. Daß die gummi-industrie mit dem neuen Material etwas anzufangen vermag, zeigen von der continental-caoutchouc und Guita percha-co. Zu Hannover hergestellte Gebrauchsgegen stände, Automobil und Fahrradreifen, sowie Kabel und Schnüre Die Frage, bis wann es der Technik ge lungen sein wird, den künstlichen Kautschuk so her zustellen, daß er den Kampf mit dem natürlichen auf zunehmen vermag, kann heute noch nicht beantwortet werden; daß es aber gelingenwird, istzweifellos.'

Paperback. Condizione: New. Print on Demand. This book, first published in 1912, explores the creation of synthetic rubber. Before the book's publication, rubber was solely a natural product harvested from trees in tropical regions. The author explains that an alternative source for rubber was rapidly becoming a necessity, as the rapidly growing automobile industry was increasing the global demand for rubber at an unsustainable rate. Chemists were tasked with creating a synthetic form of rubber that could replace the dwindling natural supply. Compounding this challenge was the fact that rubber's molecular structure was poorly understood at the time. The author describes the experiments conducted by scientists like Fritz Hofmann and Carl Coutelle, and the eventual discovery of processes to cost-effectively produce synthetic rubber. The advent of synthetic rubber transformed the automotive industry, allowing for mass production and a reduction in consumer costs. This book remains a valuable resource for chemists and those interested in the history of synthetic materials.
