Process for producing linear unsaturated dimers of alpha -alkyl styrenes |
| 摘要 |
A process for producing a linear unsaturated dimer of alpha -alkyl styrenes by heating alpha -alkyl styrenes in the presence of a silica-alumina catalyst, said catalyst consisting of alumina and silica in a weight ratio of 83/17</=Al2O3/SiO2</=96/4 and being substantially free of alkali is disclosed.
