If solvents are important i n your processing or develop ment, take a look at this nonflammable chlorinated hy drocarbon which offers s o many operating advantages, including relatively l o w toxicity. Try it for these appli cations : Resin Casting—films and other forms. Solution of oils, fats, greases, waxes, natural and syn thetic rubbers, photo films, etc. Extractions o f fine chemicals, alkaloids, pharmaceuticals. Component of low-pressure aerosol mixtures, cold clean ers, paint removers.
Low-temperature brine a n d coolant. Try it for processes o r extractions where mixed sol vents are desirable o r advantageous, because methylene chloride is readily soluble i n other solvents and only slightly soluble in water. Solvent recovery is easy a n d economical, can be carried out by conventional low tem perature distillation, for methylene chloride is extremely stable, even in the vapor phase.
