Description

используют на стадии щелочного плавлени  производства 2-нафтола, а промывные воды, содержащие не более 1 вес. % нафталин-2сульфоната натри , подают на стадию гидролиза сульфомассы производства нафталин-2сульфокислоты . Выход щий из центрифуги маточник направл ют на смещение с сульфитными сточными водами производства-2нафтола с последующим выпариванием и сушкой. В результате получают сульфатсульфнтные соли с содержанием нафталин-2-сульфоната натри  не более 0,1 вес. %.used at the stage of alkaline melting of the production of 2-naphthol, and wash water containing not more than 1 weight. % naphthalene-2sulphonate sodium, served on the stage of hydrolysis of sulphatic production of naphthalene-2sulphonic acid. The mother liquor coming out of the centrifuge is sent to dislodge with sulfite effluent from production of 2 naphthol, followed by evaporation and drying. The result is a sulfate sulfate salt with a content of sodium naphthalene-2-sulfonate not more than 0.1 weight. %

Предлагаемый способ позвол ет достичь значительной экономии от наиболее полного извлечени  товарного нафталин-2-сульфоната натри ; получить сульфатсульфитные соли улучшенного качества и устранить загр знение воздушной среды пылью нафталин2-сульфоната натри .The proposed method allows to achieve significant savings from the most complete recovery of marketable sodium naphthalene-2-sulfonate; obtain improved sulfate sulfite salts and eliminate the pollution of the air environment with sodium naphthalene2-sulfonate dust.
