Synthesis of valuable intermediate products from natural rubber under supercritical alcohol conditions

In this study, thermal liquefaction of natural rubber was performed using different alcohols to produce valuable intermediate product. The experiment was conducted in autoclave reactor at different temperatures (250–375 °C), different solvent-to-natural rubber mass ratios (0.5:1 to 4:1), and at diff...
