O-CRESOL FOR SYNTHESIS 500 ML

Application

o-Cresol can be used as a starting material to synthesize:

• Carvacrol by alkylation reaction with propylene or isopropyl alcohol in the presence of Zr/mesoporous silica as a catalyst.
• Polyisobutylenes by selective cationic polymerization of isobutylene using AlCl₃ as a catalyst.
• Poly(o-cresol) via oxidative coupling polymerization reaction in the presence of substituted pyridine/CuCl catalysts.
