Acetic acid , the concentration of which is close to 100%, is called glacial. 70–80% aqueous solution of acetic acid is called acetic essence, and 3–15% is called vinegar . Aqueous solutions of acetic acid are widely used in the food industry (food additive E260) and household cooking, as wel..
Dichloromethane (methylene chloride) is a highly mobile and volatile liquid, it has a sweetish odor, which is characteristic of all halogen derivatives. This chemical liquid was first synthesized in 1840, obtained by keeping the composition of methyl chloride with chlorine on light. Among all hal..
Activated carbon is a spongy substance that is extracted from various carbon-containing materials, of natural origin. It is made at high temperatures (about 1000˚ C). The result is a substance that is almost one hundred percent carbon. Coal has a rather unsightly appearance, granules or black p..
Anionites are synthetic ion-exchange resins capable of exchanging anions. Most often, anion-exchange resins are a copolymer of styrene and divinylbenzene. Anionites are insoluble particles in the form of spherical granules, about 1 mm in diameter. Most often they are light or white in color. ..
Bitumen (from Lat. bitumen - mountain resin) - solid or resinous products, which are a mixture of hydrocarbons and their nitrogenous, oxygenated, sulfurous and metal-containing derivatives. Bitumen are insoluble in water, completely or partially soluble in benzene, chloroform, carbon disulfide an..
Butyl acetate is an ester. Colorless or slightly yellowish liquid with a characteristic odor. Butyl acetate is slightly soluble in water; miscible with organic solvents and vegetable oils. Butyl acetate is a good solvent for nitrocellulose, chlorinated rubber, glyphthalic resins and other film-form..
Cationite is small granules (about 1 mm in diameter) from light yellow to dark brown. It is a monofunctional strongly acidic ion exchange resin with a gel structure, high molecular weight polymer substance. Copolymer of styrene and divinylbenzene. It contains one type of fixed ions - sulfo g..
Chloroacetic acid is acetic acid in which one of the hydrogen atoms in the methyl group is replaced by a free chlorine atom. It is obtained by reacting acetic acid with chlorine. The main raw material for production is acetic acid. Chloroacetic acid can also be obtained by hydrolysis of trichloreth..
Creosote is a colorless (sometimes yellowish or yellowish-green), flammable, hardly soluble in water, oily liquid with a strong odor and a pungent taste, obtained from wood and coal tar. It is a mixture of phenols, mainly guaiacol and cresols. Application Wood creosote is used for tuberculosis ..
Plasticizers are substances that are added to the composition of polymeric materials to impart plasticity during processing and further operation. CONTACTS The use of plasticizers allows to reduce the temperature of technological processing of compositions, improve the frost resistance of po..
Diphenylamine - colorless crystals that darken in the light, melting point 54-55 ° C, boiling point 302 ° C. Easily soluble in diethyl ether, benzene, acetone, carbon tetrachloride. Solubility at 25 ° C in 100 g ethanol - 44 g, methanol - 57.5 g, water - 0.03 g. Diphenylamine is a precursor ..
Epoxy resin is a type of synthetic resin that can polymerize to a solid state when a hardener is added. Cured resins are characterized by high adhesion to metals, glass, concrete, as well as mechanical strength, heat, water and chemical resistance, good dielectric properties. Epoxy resins are capab..
