摘要
3-methyl-3-butene-1-ol (MBOH) was synthesized in a batch stirred tank reactor using isobutylene and formaldehyde in supercritical isobutylene without catalysts at 513.15~543.15 K and 15~20 MPa. The structures of main products were characterized by gas chromatography-mass spectrometry (GC-MS) and nuclear magnetic resonance (NMR), and the main reaction network and corresponding kinetic model were established. The experimental data was fitted to obtain reaction rate constants of isobutylene-formaldehyde and MBOH-formaldehyde reactions under different temperatures. The results show that the activation energies of these two reactions are 101.95 and 83.99 kJ∙mol -1 , respectively. Increase of reaction temperature can enhance MBOH selectivity. © 2018, Editorial Board of Journal of Chemical Engineering of Chinese Universities". All right reserved."
