| Abstract: | 3-methyl-3-buten-1-ol was synthesized through heterogeneous catalysis by Prins condensation with 2-methyl propene and paraformaldehyde.The Process conditions were simple and easy to industrialize,have a broad development prospects.It had great economic and social benefits.Studying on process conditions in fixed bed reactorn shows that the yield of the reaction was the largest when reacted at 240 ℃,volume airspeed 0.5 h-1 and the mol ratio between isobutylene and paraformaldehyde was 2︰1. |
