Determination of triphenyltin compounds and tricyclohexyltin hydroxide by gas-chromatography of their derivatives

A gas-liq. chromatog. method is reported for detg. the triphenyltin derivs. (Ph3SnR) and tricyclohexyltin hydroxide (Cy3SnOH) after their conversion (via the Grignard reaction catalyzed by CuCl) to tetraphenyltin (Ph4Sn) and tricyclohexylphenyltin (Cy3PhSn). The recovery of Ph4Sn and Cy3PhSn was satisfactory in the range 50 to 3000 mg. Different columns were tested using flame-ionization detection. For both derivs. (Ph4Sn and Cy3PhSn), the response is linear from 0.05 to 3.00 mg. Results of thermal anal., IR spectroscopy, and mass spectrometry are reporte

Some chemical-physical properties of tricyclohexyltin hydroxide and its analytical determination

A gas-liq. chromatog. method is reported for detg. tricyclohexyltin hydroxide in powders marketed as insecticides, after its extn. with CHCl3. Different glass columns were tested using flame ionization or electron capture detectors. The linearity of the response was from 0.1 to 2.5 mg using the flame ionization detector and from 0.5 to 5.0 ng using the electron capture detector. Its recovery from the analyzed samples is satisfactory. Results of thermal anal., I.R. spectroscopy and mass spectrometry were also reporte

Gas-liquid chromatographic analysis of bioresmethrin

Bioresmethrin was detd. by gas chromatog. using flame ionization or electron capture detectors. The detection threshold for both detectors was 0.1 mg. In the presence of piperonyl butoxide, it was detd. as 2-benzyl-4-hydroxymethylfuran, an alk. hydrolysis product. Principal gas chromatog. parameters were: column packing (e.g. 3% OV-101 absorbed on 100-140 mesh Chromosorb G-HP); carrier gases (N2 for flame ionization and Ar-CH4 mixt. for electron capture); detector and injection port temps., 300
