Isolation of some high-boiling or ganometallic compounds by preparative gas chromatography
Preparative gas chromatography is proposed to isolate some high-boiling organometallic compounds. Isolation of high-boiling substances should be conducted at a column temperature significantly below the boiling point, because most isolated compounds are ...
