Redox ion exchangers based on sulfochlorinated copolymers of styrene and divinylbenzene

Conclusions The authors have obtained redox polymers by reacting sulfochlorinated copolymers of styrene and divinylbenzene of both ordinary and macroporous structures with quinones, di-, and trihydroxybenzenes or dialkyl esters of hydroquinone; their properties have been studied.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 9, pp. 2126–2128, September, 1970.     

Synthesis and Physicochemical Study of Polyfunctional Ion Exchangers Based on Dextramine Waste from Levomycetin Production

New polyfunctional anion exchangers are synthesized from dextramine (waste from levomycetin production) by condensation of its glycidyl ethers with certain polyamines. The polycondensation conditions are optimized, and physicochemical properties of the resulting ion exchangers are studied.     

N-substituted 2, 5-dimethyl-4-ethynyl(vinyl)piperid-4-ols

They -isomers of 1-(3-chlorobuten-2-yl)- and 1-benzyl-2,5-dimethyl-4-ethynylpiperid-4-ols (I, II) and of 1-(3-chlorobuten-2-yl)-2,5-diemethyl-4-vinylpiperid-4-ol (III) and the quaternary salts of compounds I–III and of the -isomers of the 1,2,5-trimethyl-4-ethynyl-(vinyl)piperid-4-ols [1] have been synthesized.
