摘要： A method is disclosed for volatile inhibition and transport of inhibitor in the volatile phase to produced liquids of corrosion in a gas lift process in which a lift gas is pumped into a well to facilitate petroleum production of the well. The method comprises introducing to the lift gas a corrosion-inhibiting amount of a dihydrothiazole of the formula ##STR1## wherein R, R', R", R'", and R.sup.4 are independently selected from among hydrogen and alkyl groups of up to about 3 carbon atoms, provided that the total number of carbon atoms of R, R', R", R'" does not exceed about 14.
