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.

The plant «Omsky kauchuk» is one of the leaders among the Russian synthetic rubber producers. The plant's birthday is considered to be October 24, 1962, when the first briquette of Omsk rubber was produced. In as little as a year, the enterprise managed to derive divinyl, isopropylbenzene, and the first specification-grade alphamethylstyrene.

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.

New Window. The rate constant for the vapor-phase reaction of n-propylbenzene with photochemically-produced hydroxyl radicals is 6.0X10-12 cu cm/molecule-sec at 25 °C (1). This corresponds to an atmospheric half-life of about 2 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm (2).
