Calcium Lignosulfonate properties
Calcium-lignosulfonate-Properties
Calcium lignosulfonate is a multicomponent polymer anionic surfactant, the appearance of a pale yellow to dark brown powder, slight aroma, molecular weight is generally 800 to 10000, with strong dispersion, bonding, chelation. Soluble in water but does not dissolve in any common organic solvents. Its 1% aqueous solution pH of about 3 to 11.
Lignin sulfonate is an anionic surfactant, the aqueous pulp and sulfur chloride and sulfite reaction product, a byproduct of the production of pulp, usually 4 – hydroxy – 3 – methoxy Multi copolymers. Because different types of wood, different sulfonation of lignin sulfonate molecular weight ranging from 200 to 10,000 by the chemical structure has not been determined. Generally wood qualities of low molecular weight sulfonates, mostly straight, associating together in solution; polymer is a branched multi-lignosulfonate, in an aqueous polymerization medium, shows the dielectric behavior.
Sodium gluconate is the most common monosaccharide, is alcohol aldehydes, molecular formula is C6H11O7Na. As colorless crystals or white powder, the density 1.544g / l, the monohydrate m.p. 83 ℃. Soluble in water, slightly soluble in alcohol, insoluble in ether, toxic pollution, will not cause pollution.
Amino benzene sulfonate formula C6H10O5NSNa, as flash flaky crystals with two molecules of water of crystallization. Soluble in water, the aqueous solution is neutral.
Fatty alcohol sulfate formula C12H25Na SO4 density of 1.09 (g / l),: white to pale yellow powder, slight special smell. Melting point 180 ~ 185 ℃ (decomposition), soluble in water
Formula formaldehyde HCHO, colorless aqueous solution or gas. A pungent odor. The liquid in the cold storage for a long time easily turbid at low temperatures precipitation is formed trioxane. Evaporates some formaldehyde escape, but most become trioxymethylene. Is a strong reducing agent in alkaline Shihai trace immunogenicity stronger. The air can be slowly oxidized to formic acid. With water, ethanol, acetone and other organic solvents in any immiscibility. pH 2.8 ~ 4.0. Relative density 1.081 ~ 1.085. Melting point -118 ℃, boiling point -19.5 ℃, flash point 60 ℃. Flammable. Low toxicity and median lethal dose (rat, oral) 800mG/kG. Its vapor can strongly stimulate the mucous membranes, carcinogenic, are highly toxic.
