In continuation of our reports on the chemical constituents of Croton tonkinensis Gagnep. (Euphorbiaceae)  this paper deals with the isolation and structure elucidation of two long chain alkyl alcohols. Two compounds 1 and 2 were isolated by repeated silica gel column chromatography of the n-hexane soluble fraction obtained from the methanol extract of the dried leaves of C. tonkinensis by liquid - liquid fractionation . The long aliphatic chains of both compounds 1 and 2 were characterized by the 1 H and 13 C NMR spectra: H 0.88 (3H, t, J = 6.6 Hz), C 14.
Alkyl nitrites are highly volatile organic solvents of aliphatic alcohol esters of nitrites . Amyl nitritea, butyl nitrite and isobutyl nitrite are the representative alkyl nitrites; their boiling points are 98, 78 and 67 °C, respectively. Amyl nitrite is being widely used as a detoxicant for cyanide poisoning, because alkyl nitrites oxidize hemoglobin in erythrocytes to yield methemogloblin, which is bound with cyanide to inactivate it .
This book has evolved from over a quarter-century of research that concentrated on
delineating the aqueous coordination reactions that characterize the vanadium(V)
oxidation state. At the beginning of this time period, only a minor amount of research
was being done on vanadium aqueous chemistry. However, the basic tenets of
NMR spectroscopy were being elaborated, and some of the influences of ligand
properties and coordination geometry on the NMR spectra were being ascertained.
