The 4-5-min fraction was further fractionated with a lesspolar eluent, acetonitrile-water (1:3, v/v). In acetonitrile solution the monocyanopolyynes are unstable and disappear completely after several days if stored at room temperature. The extracts were centrifuged for 10 min at 16,000 g, and the pellets were re-extracted twice with the same volume of acetonitrile. The acetone from the crude extracts was removed by evaporation under a stream of nitrogen and dry residues were dissolved in 100% (v/v) acetonitrile. The mobile phase was acetonitrile:water (75:25) at a rate of 1 ml/min. The solvent was acetonitrile:water (83:17) at a flow rate of 1.5 ml min-1 at room temperature. The column was washed with 2 ml of 2 % acetonitrile and vacuum dried for 2 min prior to elution of the oryzalin with 2 ml of 100 % acetonitrile. Substrate radical intermediates are involved in the soluble methane monooxygemase catalyzed oxidations of methane, methanol and acetonitrile. The mobile phase, at a flow rate of 0.15 ml minx1, contained the mixture of two solvents, acetonitrile and water, both acidified with 0.5% (v/v) acetic acid. The peptides in water/acetonitrile (0.5 l) were deposited on a thin layer of -cyano-4-hydroxycinnamic acid made by rapid evaporation of a saturated solution in acetone. In the alkylation of acetonitrile, for instance, yields of monoalkylated product are low in most cases. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license.
