The inadequate treatment of waste tire is currently a major environmental and economical issue. In this study, the effective solubilization of waste tire into diethyl ether was attained by the thermal treatment in organic solvent at 200–300 °C. Not only aromatic, but also aliphatic alcohols were effective on the solubilization. Among aliphatic alcohols, 1-heptanol was the most effective solvent on the solubilization and reached near 70% in the thermal treatment at 200 °C under inert atmosphere. Model compound study containing sulfur–sulfur bond suggests the disulfide–alcohol exchange reaction leading devulcanization of the waste tire.

废轮胎在高温有机流体中的化学回收

当前对废轮胎的处理不充分是一个主要的环境和经济问题。在这项研究中，通过在200–300°C的有机溶剂中进行热处理，可以将废轮胎有效地溶解为乙醚。不仅芳族醇，脂族醇也对溶解有效。在脂族醇中，1-庚醇是增溶最有效的溶剂，在惰性气氛下于200°C的热处理中，其含量接近70％。包含硫-硫键的模型化合物研究表明，二硫化物-醇交换反应导致废轮胎的脱硫。
