Abstract: FIELD: chemical industry. SUBSTANCE: present invention describes method of preparing isoprene from isopentane. Said method comprises oxidizing isopentane with the resulting tert- amyl hydroperoxide, epoxidizing 2-methyl-2-butene, thermocatalytically decomposing the resulting 2-methyl-2- butene oxide to produce isoprene and methyl isopropyl ketone and dehydrating the resulting tert-amyl and secisoamyl alcohols, separating tert-amylenes by rectification, isomerizing 2-methyl-2-butyl and the latter is epoxidized. Unreacted isopentane is recycled for oxidation. Methylisopropyl ketone is removed from system or thermocatalytically decomposed to obtain additional amount of isoprene. Alternatively, isomerization is combined with isomerization of 2-methyl- 1-butene-3-ol impurity in isoamyl alcohols and/or with dehydration of isoamyl alcohols. Decomposition of methylisopropyl ketone is combined with decomposition of 2-methyl-2-butene oxide. Prior to epoxidation, isopentane is removed from oxidate with optional addition of 2-methyl-2-butene, and mixture of carbonyl compounds and C 1 -C 3 -alcohols is separated from said 2-methyl-2-butene by aqueous extraction. Acetic acid is separated from oxidate by extraction with water followed by reextraction of tert-amylhydroperoxide with 2-methyl-2-butene or, after epoxidation stage, acetic acid is separated from mixture containing isoamyl alcohols by azeotropic rectification with water. EFFECT: more efficient preparation method. 6 cl, 5 dwg, 5 tbl

Abstract: FIELD: processing of complex silver-containing ores and technogeneous deposits, applicable in mining industry. SUBSTANCE: to increase the content of silver and content of attendant elements Pb, Zn, Cu, Sb, Sn, Mo Ni, Co, Bi by 2.1 to 2.5 times and technogeneous deposits involved in processing with the aid of nuclear physical grading and lump separation, mining pulp is divided into concentrated products, intermediate products IP-1, IP-2, IP-3 and final tailings. For processing of unyielding difficult-to-concentrate complex silver- containing ores operations of two-stage bacterial- chemical leaching of silver-containing ores are introduced with regrinding of collective concentrate after each stage of leaching. In processing of unyielding ores extraction of silver from silver-lead and silver-tin ores for the IP-3 product is accomplished with employment of sulfur dioxide; the content of silver in grading products and lump separation is determined by using the linear correlation bonds of silver with byproduct elements by Pb, Zn, Cu, Ni, Co, Bi, Sb, Sn, Mo indicators. To enhance the sensitivity and selectivity of nuclear-physical grading and lump separation, criterion of separation of ores according to the product of analytical parameters of the respective elements-indicators is determined. Intermediate products are directed to heap bacterial-chemical leaching in summer only, intensification of bacteria activity is realized, and volumes of intermediate products are regulated with employment of a microcomputer.
