    摘要： A new composition of matter is revealed which comprises a copolymer of a surface active quaternary ammonium monomer salt and from 50 wt % to 97 wt % of acrylamide. The new copolymers can have molecular weights substantially greater than 10,000 and still remain water soluble and surface active.

    摘要： The corrosion of iron and steel surfaces by an aqueous alkanolamine conditioning solution used to remove CO.sub.2 from a gas stream is effectively inhibited by a combination of a vanadium containing ion and a soluble cobalt salt. This system allows the use of higher amine concentrations which in turn allows a higher carbon dioxide loading with low corrosion thereby improving the energy efficiency of the gas sweetening process.

    摘要： A process is provided for recovering substantially pure triethylenediamine in liquid tertiary amine solutions directly from the crude triethylenediamine reaction mixture without resort to a need to purify the triethylenediamine by crystallization. The process includes initially admixing a tertiary amine with a crude triethylenediamine liquid reaction product mixture. The admixture thus formed is then distilled under conditions such that the triethylenediamine and tertiary amine codistill as a substantially pure triethylenediamine solute in liquid tertiary amine solution. The collected codistillate being substantially free of reaction by-products can be used directly to catalyze urethane systems.

The ratio of amine equivalent: acid ranges from 1:0.5 to 1:1.The aqueous fluids optionally incorporate ethylene glycol. They are useful for water/glycol based hydraulic fluids, cosmetics and surfactants.
