Abstract: FIELD: resin industry. SUBSTANCE: integrated processing of larch wood gives following isolated native bioflavanoids: dihydroquercetin, dihydrokaempferol, naringenin, wood resins, oils, oligosaccharides, and insoluble wood biopolymer. Integrated processing of wood and needles of larch comprises extraction of natural substances from destroyed wood with water-containing organic solvent under conditions wherein extraction material components are fluidized. Extraction material is then separated into extract and solid phase, which is carbon-containing wood polymer. Organic phase of extract is absorbed by solvent. Resulting organic and aqueous phases are treated to isolate desired products. All processing stages are carried out under oxygen-free atmosphere. Extraction is effected at temperature from 0 to 40 (r)  using, as water-containing organic solvent, emulsion of nonpolar aliphatic hydrocarbon with boiling point no higher than 90 (r)  and methyl tert-butyl ether in deionized water at weight ratio (0.5-1):(0.6-4.0):(4.0-10.0), respectively, while weight ratio of destroyed wood to nonpolar hydrocarbon (contained in emulsion) ranges from 1.0:0.5 to 1.0:1.0. After separation of extraction material, solid phase is washed with deionized water and routed to isolation stage. Water/hydrocarbon/ether extract is separated into stratified hydrocarbon-ether phase of oils, resins, and bioflavanoids and aqueous oligosaccharide phase, form which arabinogalactan is isolated. Absorption of liquid hydrocarbon/ether phase of extract with deionized water is effected at 90-94 (r) , while simultaneously distilling away volatile hydrocarbons and methyl tert-butyl ether giving rise to formation of immiscible phases, followed by isolation of oils and resins from hydrocarbon phase and isolation of bioflavanoids from aqueous phase. EFFECT: reduced power consumption and cost price of desired products. 4 cl, 1 dwg

Abstract: Изобретение относится к способам получения очищенной концентрированной фосфорной кислоты из экстракционной фосфорной кислоты, которая может быть использована в производстве технических, кормовых и пищевых фосфатов. Способ включает введение в ЭФК (38-53% Р 2 О 5 ) серной кислоты до содержания 3-6 мас.% с последующей операцией одновременного концентрирования, отдувки фтористых соединений и адсорбции других примесей на твердых адсорбентах, которую осуществляют в едином циркуляционном контуре (концентратор-дефторатор – адсорбционная колонна – сборник ЭФК) при температуре 96-105°С. В конце процесса остаточное содержание сульфатов снимают введением в фосфорную кислоту соединений стронция в количестве, обеспечивающем соотношение Sr 2+ /SO       2-   4        в кислоте, равное 1,07-1,2, при этом соединения стронция вводят в виде водной суспензии, а стадию осаждения осуществляют при той же температуре, что и все предыдущие стадии. Способ позволяет снизить концентрацию соединений фтора, кремния, железа, алюминия, серы, свинца и мышьяка до норм, предусмотренных ГОСТом на пищевую термическую фосфорную кислоту, и упростить технологическую схему путем исключения из нее операций очистки органическими экстрагентами. 1 з.п.ф-лы, 1 табл.
