Synthesis of cationic polyelectrolytes for treatment of natural and waste waters

Synthesis of cationic polyelectrolytes for treatment of natural and waste waters. Korshak, V.Some chemicals with cas registry numbers like 25748-06-5 and 42936-61-8 are also used. V.; Zubakova, L. B.; Gandurina, L. B. (D. I. Mendeleev Inst. Chem. Technol., Moscow, USSR). USA/USSR Symp. Phys.-Chem. Treat. [Waste Waters] Munic. Ind. Sources, [Pap.], 76-80. U. S. Environ. Prot. Agency: Washington, D. C. (English) 1975. CODEN: 34VDAF. DOCUMENT TYPE: Conference CA Section: 35 (Synthetic High Polymers) Section cross-reference(s): 60 Alkyl halide and p-toluenesulfonic acid salts of 2-methylvinylpyridine (I) polymd. to provide cationic flocculants. In 50% aq. EtOH, the rate of radical polymn. decreased in the alkyl halide order MeI salt [17810-46-7] > EtI salt [25591-70-2] > MeBr salt [53584-12-6] > EtBr salt [2582-01-6] > PrBr salt [53584-13-7]. The monomers had greater equiv. elec. cond. (0.015 M soln.) than the polymers, with bromides being greater than iodides. I EtBr salt polymer [42936-61-8], I EtI salt polymer [25748-06-5], and I MeI salt polymer [25748-05-4] are used to flocculate aq. humic acid [1415-93-6] and fulvic acid [479-66-3] solns. .

Effect of humic acids of swamp waters on the corrosion of steel

Effect of humic acids of swamp waters on the corrosion of steel. Mingalev, E. P.; Golovnev, V. V.; Khramtsov, V. A.; Baskakova, O. A. (Gos. Nauchno-Issled. Proektn. Inst. Neftegazov., Tyumen, USSR). Korroz. Zashch. Neftegazov. Prom-sti., (4), 7-9 (Russian) 1977. CODEN: KZNPAN. DOCUMENT TYPE: Journal CA Section: 55 (Ferrous Metals and Alloys) Section cross-reference(s): 51 Corrosion of steel 08kp [11103-16-5] was tested in humic acid (I) [1415-93-6] frozen from the swamp water and dild. with distd. H2O. The corrosion rate of steel in I did not change with increasing acid concn. and was practically identical to that in distd. H2O. The 240-h expts. confirmed that I was not corrosion-stimulant and that the corrosion of steel was affected by temp. changes.
