Abstract
The present survey is limited to the application of methods for establishing the chemical composition of paper. The subject is reviewed under the following headings: literature, sampling and preparation of sample, moisture, fiber quality methods (alpha-, beta-, and delta-cellulose), copper number, viscosity, and lignin content), sizing and coating materials (rosin size, starch, glue or gelatin, and casein, determination of amount of coating, and waxes and oils), fillers, and white coating pigments (including distribution of filler), acidity of paper, inorganic residues, and impurities (sulfates and chlorides, conductivity of water extracts, sulfides and reducible sulfur, tarnishing or corrosion tests, and metals and metallic compounds), coloring materials (dyes and colors and color pigments), biological control agents (phenyl-mercuric compounds, pentachlorophenol, phenols, quaternary ammonium compounds, biphenyl, and insecticides), synthetic resins (wet-strength resins, viscose, and general identification of resins, sizings, and impregnating materials), synthetic and natural rubbers, polysaccharides and gums, softeners and humectants, fireproofing and flameproofing treatments, noncellulosic fibers (wool and asbestos), specks and spots, specialty papers (printing, wrapping, filter, permanent, photographic, cigarette, electrical, vegetable parchment, wet-strength, anti-tarnish and anti-corrosive, and anti-oxidant papers), and summative analysis. 323 refs. -- AATA
