METHOD FOR PREPARING ADDITION AGENT AS REGULATORS OF VISCOELASTIC PROPERTY ASSOCIATED MULTICOMPONENT PETROLEUM SYSTEMS Russian patent published in 2006 - IPC C10L1/232 C07D487/18 C08G65/332 C08G65/333 

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to a method for synthesis of novel addition agents used as regulators of viscoelastic properties of associated multicomponent petroleum systems that can be used in petroleum and petroleum chemical industry. Method involves interaction of monochloroacetic acid with alcoholic component in the presence of acidic catalysts, for example, with H⁺-form of cation-exchange resin KU-2-8, in boiling organic solvent medium and azeotropic removing formed water and the following treatment of the synthesized reaction substance with amines. As a alcoholic component methods involves using 1,2,3-tris-[(hydroxypoly(alkyleneoxy)]propanes of the general formula: wherein a + c + e (the total degree of oxypropylation) = 48-78, b + d + f (the total degree of oxyethylation) = 0-20, and 1,3,5,7-tetraazaadamantane of the formula: is used as amines in the molar ratio of reagents - propane hydroxyl derivative : monochloroacetic acid : tetraazaadamantane = 1.0:(3.0-3.2):(0.75-3.2), respectively. As a rule, as organic solvents in interaction of propane hydroxyl derivative with monochloroacetic acid method involves using aromatic hydrocarbon solvents, for example, toluene, xylene, nefras A-120/200. Usually, treatment of the reaction product of monochloroacetic acid with propane hydroxyl derivative with 1,3,5,7-tetraazaadamantane is carried out in polar solvents medium at temperature 40-85°C. As a rule, mixtures of water with low-molecular alcohols, for example, ethanol, isopropanol are used as polar solvents in the volume ratio water : alcohol = 1.0:(15-25).

EFFECT: improved method of synthesis.
