Abstract

Inductively coupled plasma-atomic emission spectroscopy is used to determine the concentration of a silicon impurity that appeared in some samples of unleaded fuel from a metropolitan area in 1984 and 1985. Silicon-29 NMR is used to identify the contaminant as the cyclic silicone, octamethylcyclotetrasiloxane. This silicone tetramer is also observed in the NMR of a commercial coating, a xylene solution of linear and cyclic silicones, used as a moisture barrier in the electronics industry.
