Winston Churchill, among others, criticized American use of napalm in Korea, calling it "very cruel", as the US/UN forces, he said, were "splashing it all over the civilian population", "tortur[ing] great masses of people".

Copper naphthenate adhesion promoters, lubricant additives, and catalysts where oil solubility is required. Naphthenic acid is a complex group of carboxylic acids with the general formula CHO where n indicates the carbon number and z specifies the hydrogen deficiency resulting from ring formation. Naphthenic acids occur naturally in crude oil at varying concentrations, and their composition varies with the crude oil composition and the conditions during refining. Crude oils with total acid number (TAN) as little as 0.5 mg KOH/g acid or petroleum fractions greater than about 1.0 mg KOH/g oil usually qualify as a high acid crude or oil. At the
