摘要：

An extraction method for butyl-, cyclohexyl-, octyl- and phenyltin compounds from edible oils was developed using 0.05% tropolone in 0.04M HCl/methanol. Cooling the methanol extracts in a dry ice/methanol bath removed approximately 64% of nonvolatile coextractives without affecting recoveries. Methyl derivatives formed by Grignard reaction were quantitated by ps chromatography-atomic absorption spectrometry. Edible oils sold in poly(vinyl chloride) containers had ng/g levels of dioctyl- and monooctyltin. GC-MS confirmed the presence of octyltin and did not detect any other organotin compounds in the extracts.
