P-CYMENE (P-METHYLISOPROPYLBENZENE) PRODUCTION PROCESS

FIELD: industrial organic synthesis. SUBSTANCE: process involves skeletal isomerization and dehydrogenation of alpha-pinene in presence of zeolite- containing cracking catalyst (Z-10) preliminarily activated for 1-2 h at 300-550 C in nitrogen flow. Process is carried out for 2-8 h at 150-170 C and n...

Zusammenfassung:FIELD: industrial organic synthesis. SUBSTANCE: process involves skeletal isomerization and dehydrogenation of alpha-pinene in presence of zeolite- containing cracking catalyst (Z-10) preliminarily activated for 1-2 h at 300-550 C in nitrogen flow. Process is carried out for 2-8 h at 150-170 C and nitrogen pressure 5 atm. EFFECT: increased yield of product. 1 tbl, 10 ex
