Title Study of the toxic substances formed in the oxo process
Original title Izučenie toksičnyh veščestv, obrazujuščihsja v processe oksosinteza [in Russian]
Bibliographic information Aug. 1985, No.8, p.51-54. 12 ref.
Abstract In the oxo process, olefins are reacted with carbon monoxide and hydrogen to yield alcohols; aldehydes are intermediate reaction products. Various volatile by-products may also be formed, so that workplace air can be contaminated by a wide range of substances. To identify and quantitate these contaminants, air was sampled by being drawn through a glass tube packed with Tenax sorbent. The material collected was desorbed onto a glass capillary gas-chromatography column coated with SE30. The gas chromatograph was coupled to a mass spectrometer. 165 organic compounds were identified. They included saturated, unsaturated and aromatic hydrocarbons, terpenes, halogenated hydrocarbons, nitriles, thiocyanates, sulfides, alcohols, ethers, aldehydes and ketones.
