Methods for inhibiting pyrophoric iron sulfide activity are disclosed. Methods are disclosed for inhibiting the oxidation of iron sulfide to inhibit pyrophoric activity. The methods comprise contacting iron oxides and/or iron sulfide with a liquid, solution, aerosol, or gaseous inhibitor comprising aromatic hydrocarbons such as alkyl substituted benzenes.

Inhibition of pyrophoric iron sulfide activity

In the thermal processing of crude alkanolamines, a method of inhibiting color formation in the alkanolamines comprising adding an amount, effective for the purpose, of an alkali metal hydroxide or sulfite, or mixtures thereof.

Inhibitors of color formation in alkanolamines

Disclosed are methods for dispersing sulfur in aqueous systems comprising adding an alkylcarboxylic acid compound to the system. This prevents fouling of the aqueous system by the precipitated sulfur.
