Organotin Compounds in Fatty Extractants

The extractability of labelled organotin compoimds (di-n-octyl [ C] tin-dithioglycollic acid-2-ethyl- -hexyl ester) from rigid polyvinylchloride (PVC), low and high-density 

Adcock and Hope [7] have described methods for the determination of the extractability of dioctyl-5,5-bis-(iso-octylmercapto) acetate stabilisers from PVC into sunflower seed oil. 

Belhaneche-Bensemra and co-workers [8] used atomic absorption spectrometry to determine the levels of tin and other metals in sunflower oil containing an organotin stabiliser during a migration test carried out at 45 °C with agitation. Tin levels in the oil ranged from 395 ppm (3 days exposure) to 650 ppm (12 days exposure).
