POWERFUL SOLVENT... POWERFUL PROBLEM SOLVER
An outstanding application of M-Pyrol lies in its use as a solvent in production of polymer-based wire insulation coatings. GAFM-Pyrol—N-methyl-2-pyrrolidone —is a strong solvent for many resins and other materials. But it is also remarkable for its versatile ability to put many processes on their best behavior. Stable structure—Its lactam structure imparts an unusual degree of thermal and chemical stability that permits its use over extended periods. Physical properties—Its low order of toxicity simplifies handling and use. Low viscosity facilitates heat transfer and flow. Its high boiling point, low freezing point, and non-corrosiveness combine to simplify processing and minimize operating costs. Solvent uses: Selective solvent for acetylene; butadiene recovery; removal of hydrogen sulfide and other sulfur compounds from sour gas, and removal of
air pollutants from stack gases; solvent for cuprous cyanide in the Rosenmund¬ von Braun synthesis of aromatic ni¬ triles; recovery of aromatics from mixtures in petroleum refining; decolorizing petroleum oils and waxes. Its high solvency for numerous difficultly soluble resins makes M-Pyrol an efficient solvent for spinning, surface coating, stripping, casting and solvent welding operations. And, since it is miscible with so many common solvents, including water, MPyrol enables the processor to bridge many compatibility problems and achieve optimum volatility and solvency patterns. Reaction promoter—As a mildly alkaline compound and highly efficient solvent, M-Pyrol improves reaction rates and stimulates high yields in many
syntheses in which acid is liberated. It thus offers a successful commercial route in certain reactions that would otherwise be difficult or uneconomic. Examples: alkylation, ethynylation, vinylation, the preparation of carboxy¬ lic acids and derivatives, carbohydrate reactions, and others.
