Summary:FIELD: high effective plasticizer for concrete mixes. ^ SUBSTANCE: claimed method includes sulfonation of naphthalene cut from petrochemical process, in particular naphthalene cut of process stream from benzene production, followed by condensation with formaldehyde and neutralization of obtained product with alkali. Naphthalene cut contains (mass %) naphthalene 96.4-99.5; methylnaphtalene 0.01-0.2; biphenyl 0.001-0.1; low boiling additives (e.g. alkyl benzene, methylinden, tetralin_ 0.5-3.6. ^ EFFECT: enhanced raw base for production of concrete mix plasticizers. ^ 4 cl, 1 tbl
