Production of Cumene. Cumene or isopropylbenzene, is manufactured exclusively by alkylation of benzene with propene. In the most important industrialized countries, propene used for production of cumene accounts for 7-8% of the total propene consumption: The reaction takes dace either in the liauid or gas Dhase.

Abstract The catalytic system N-hydroxyphthalimide–Fe(III) is used for the first time in the aerobic oxidation of alkylbenzenes to the corresponding hydroperoxides. It is shown that micro amounts of Fe(асас)3 or Fe(benz)3 increase the efficiency of radical catalyst N-hydroxyphthalimide; as a result, hydroperoxidation of ethylbenzene and isopropylbenzene proceeds at temperatures of …
T Mill, D G Hendry, H Richardson. PMID: 17729869 DOI: 10.1126/science.207.4433.886 Abstract Photooxidation of cumene (isopropylbenzene) and pyridine in dilute solution in natural waters gives products characteristic of reactions with alkylperoxy (RO(2).) and hydroxyl (HO.) radicals. On the basis of the rates of ...
A previously uncultured Propionibacterium was isolated from a highly diluted sample (10-6 mL) of activated sludge of paper mill effluent. The isolate MOB600 was able to grow on anisole, phenetole, benzene, toluene, phenol, styrene and biphenyl, although it used only limited carbon sources in the minimal media.

Riskfaktorer – Brandfarliga ämnen. Brandrisk. En brand kan sprida sig snabbt. Risk för återantändning efter släckt brand. För vätskor gäller att brännbara ångor kan sprida sig, och ge explosionsrisk vid läckage inomhus eller i avlopp. Ångorna är i många fall tyngre än luften (kontrollera på Fysdata-fliken!) och kan då samlas i lågt belägna utrymmen, t.ex. källare.

In the present study, for the first time, the separation of isopropylbenzene as a volatile organic compound (VOC) from water was investigated through the pervaporation (PV) process. Polyvinylidene fluoride (PVDF), polydimethylsiloxane (PDMS), polyether block amide (PEBA), and ethylene-propylene-diene monomer (EPDM) polymers were utilized in the …
