A rapid method is described for the determination, in aqueous systems, of two widely used
herbicides known commercially as paraquat and diquat. Pyrolysis of these herbicides under …

Following studies on the pyrolytic behaviour of quaternary ammonium salts, the work described
here throws light on the pyrolysis of the phosphorus analogues. Major differences are …

The pyrolysis of a range of simple quaternary ammonium salts in aqueous solution has been
studied by gas chromatographic procedures. The results indicate that the structure of the …

The isolation and characterization of volatile (in gas chromatographic terms) compounds
formed in "standard" sherries is described, some being noted in sherry for the first time. …

… ABRAHAM and WJ CRIDDLE * … Christofides and Criddle [4] found that for certain
compounds glass beads produced greater pyrolysis yields than the melting point tube …
