    摘要： A method for inhibiting corrosion of a metal surface bearing a corrosion product including ferrous ions is disclosed. The method comprises applying to the surface a reaction product of an alcohol and a fatty acid maleic anhydride adduct produced by a reaction between maleic anhydride and an unsaturated fatty acid. Related compositions and coated metal surfaces are also disclosed.

    摘要： A rapidly curable fluorocopolymer comprises (a) 40 to 60 mole % of fluoroolefin units, (b) 8 to 60 mole % of the monovinyl ether of cyclohexanedimethanol units and (c) 5 to 45 mole % of alkyl vinyl ether units, wherein the mole % of a =b +c. The vinyl ether group provides an enhanced polymer Tg and a primary hydroxy site in the backbone of the polymer for effective and rapid crosslinking upon curing with isocyanates. The presence of (b) +(c) in substantially equimolar amounts with (a) provides coatings having the desired hardness without brittleness, and in suitable ratio for reaction copolymerization with (a).

    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.
