Hygiene standards for chromium(VI) compounds in the work environment (as Cr(VI), except for chromyl
chloride) in different countries [3,45-48,51] Tabela 4.
chloride (10 g) was added dropwise over a period of 30 min at room temperature.
The various methods of iPP modification with a high efficiency--flame , chromo sulfuric acid , chromyl
chloride , electric discharge plasma [4-6], or UV sensitizers [7, 8]--have been used.
We are currently investigating the chemical oxidation of hopane model systems with chromyl
chloride and developing methodology for GC/MS analysis of the oxidized products.
