Examination of catalyst for α-metylstyrene oligomerization “Phosphoric Acid on Sibunit” under conditions of laboratory and industrial application

Examination of catalyst for α-metylstyrene oligomerization “Phosphoric Acid on Sibunit”... A catalyst obtained by impregnation of a mesoporous carbon carrier sibunit with orthophosphoric acid is examined under conditions of pilot plant manufacturing for producing α-methylstyrene dimer. The produced catalyzate (the product obtained with catalysis, 300 ton) containing ca. 70% of targeted 2,4-diphenyl-4-methyl-1-penetene at 95% conversion was after filtration used for control of molecular mass at producing polystyrene of different sorts. Consumption of the catalyst under optimal conditions of exploitation of the installation was ca. 1.5 kg per 1 ton of dimer at temperature ca. 50°C and volume rate ∼ 0.5 h−1. Content of 2,4-diphenyl-4-methyl-1-pentene in the dimer can be elevated to 80% by significant decreasing conversion (∼50%) and by application of solvents. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Applied Chemistry Springer Journals
