Abstract
Description
Išradimas priklauso chemijos sričiai ir gali būti panaudotas specialiose jodo gavimo , surišimo arba nukenksminimo technologijose.The present invention relates to the field of chemistry and may be used in specific technologies for the production, binding or decontamination of iodine.
Žinoma daug gamtinių ir sintetinių polimerų, kurie sorbuoja jodą [žr. kn.: MojieKy/iapHbie KOMnJieKcti nomiMepoB/E.A. ΕβκτγροΒ, P.3. XaM3aMyjiHHa H ^p.-AJiMa-ATa: HayKa, Ka3axcKoft CCP, 1988.-C.132151]. Tačiau efektyviausių jodo sorbentų - polivinilo alkoholio, polivinilpirolidono trūkumas yra tas, jie tirpūs vandenyje, o tai trukdo juos panaudoti kietų sorbentų gamybai.There are many natural and synthetic polymers known to adsorb iodine. kn .: MojieKy / iapHbie KOMnJieKcti nomiMepoB / E.A. ΕβκτγροΒ, P.3. XaM3aMyjiHHa H ^ p.-AJiMa-ATa: HayKa, Ka3axcKoft CCP, 1988-C.132151]. However, the most effective iodine sorbents - polyvinyl alcohol, polyvinylpyrrolidone - have the disadvantage of being water soluble, which prevents their use in the manufacture of solid sorbents.
Prototipu parinktas polidimetildialilamonio chloridas (PDMDAAC1) taip pat reaguoja su jodu, nes įpylus jo į vandeninį jodo tirpalą labai paryškėja tirpalo spalva (žr. tirpalų šviesos absorbcijos spektrus, pateiktus 1 priede).Prototype-selected polydimethyldiallyl ammonium chloride (PDMDAAC1) also reacts with iodine because when added to an aqueous iodine solution, the color of the solution is greatly enhanced (see light absorption spectra of the solutions in Annex 1).
Polidimetildialilamonio chlorido kaip jodo surišėjo trūkumas yra tas, kad jis yra labai tirpus vandenyje.The disadvantage of polydimethyldiallyl ammonium chloride as an iodine binder is that it is highly soluble in water.
Žinomas PDMDAAC1 gavimo būdas iš monomero dimetildialilamonio chlorido vandeniniuose tirpaluose neaukštose (iki 85°C) temperatūrose, inicijavimui naudojant peroksisulfatus [žr. VDR pat. Nr. 141029, TPK C 08 F126/04 (1979),VDR pat. Nr. 156979, TPK C 08 F 126/02 (1982)]. Kitų polidimetildialilamonio halogenidų sintezė iš jų monomerų yra žymiai sudėtingesnė, nes trukdo šalutinė - halogenu oksidavimo reakcija. Todėl polidimetildialilamonio bromidas, kuris irgi gerai tirpsta vandenyje, gaunamas sunkiau (žr. straipsnį: Youji Negi, Susumu Harada, and Osamu Ishizuka Cyclopolymerization of diallylamine derivatives in dimethyl sulforide // J Polymer Sci: Part A-l.- 1967.-Vol.5.- P.1951-1965 ). Literatūroje nerasta duomenų, apie polidimetildialilamonio jodidą (PDMDAAJ) ar jo gavimo būdus. Susintetinti įprastiniu radikalinės polimerizacijos būdu iš atitinkamo monomero greičiausiai negalima, nes jodido jono geba oksidintis dar didesnė nei bromido ar chlorido jonų (oksidacijos potencialai E° CI2/2CI' yra +1.36V, Br?/2Br‘ - + l,09V, M’ - +0,54V).Known method for the preparation of PDMDAAC1 from monomeric dimethyldiallylammonium chloride in aqueous solutions at low temperature (up to 85 ° C) by initiation using peroxysulfates [cf. GDR pat. No. 141029, TPK C 08 F126 / 04 (1979), GDR Pat. No. 156979, TPK C 08 F 126/02 (1982)]. The synthesis of other polydimethyldiallylammonium halides from their monomers is considerably more complicated due to the interference from the halogen oxidation reaction. Therefore, polydimethyldiallylammonium bromide, which is also highly soluble in water, is more difficult to obtain (see article by Youji Negi, Susumu Harada, and Osamu Ishizuka Cyclopolymerization of Diallylamine Derivatives in Dimethyl Sulforide). - P.1951-1965). No data were found in the literature on polydimethyldiallyl ammonium iodide (PDMDAAJ) or its preparation. Synthesis by conventional radical polymerization from the corresponding monomer is unlikely because the iodide ion is capable of oxidizing even more than the bromide or chloride ions (oxidation potentials E ° Cl2 / 2Cl 'are + 1.36V, Br? / 2Br' - + l, 09V, M ' - + 0.54V).
Šio išradimo tikslas - išplėsti jodą sorbuojančių medžiagų asortimentą, sukuriant mažai vandenyje tiųpią ir efektyviai jodą sorbuojančią medžiagą.Šis tikslas pasiekiamas, pagaminant polidimetildialilamonio jodidą.Jis gaunamas sumaišius polidimetildialilamonio chlorido ir neorganinio jodido tirpalus, esant moliniam komponentų santykiui 1:1. Mainų reakcija vyksta kambario terųperatūroje pagal'lygtį:The object of the present invention is to expand the range of iodine sorbents by providing a low water soluble and efficient iodine sorbent. The exchange reaction occurs at room temperature according to the condition:

Susidaro mažai tirpaus PDMDAAJ nuosėdos. Ši reakcija įrodyta nustačius išplautose ir išdžiovintose nuosėdose Kjeldalio metodu azoto kiekį, %, (rasta 5,14 %, teoriškai PDMDAAJ azoto turėtų būti 5,51 %). Tai patvirtinta chromatografijos popieriuje būdu (eliuentas - vanduo, ryškinta techniško eterio garais, o išsiskyręs jodas užtvirtintas 0,1%-tiniu krakmolo kleisteriu). Laisvi jodido jonai iš reakcijos mišinio išnešti tik naudojant KI kiekį, didesnį už stechiometrinį. Melsva jodo dėmė popieriuje identifikuota, išmatuojant leukometru (firma Kari Ceis, Jiena) šviesos atspindžio koeficientą R. Duomenys pateikti 1 lentelėje.A low soluble precipitate of PDMDAAJ is formed. This reaction has been demonstrated by determination of the nitrogen content in the washed and dried sediment by the Kjeldahl method,% (found 5.14%, theoretically PDMDAAJ should be 5.51%). This was confirmed by paper chromatography (eluent: water eluted with technical ether vapor and liberated iodine in 0.1% starch paste). The free iodide ions were removed from the reaction mixture only using an amount of KI greater than stoichiometric. The bluish iodine stain on the paper was identified by measuring the light reflectance R on a leukometer (Kari Ceis, Jiena).

Polidimetildialilamonio jodidas, gautas mainų reakcijos būdu, yra baltos spalvos smulkiadispersinė amorfinė medžiaga. 240-260°C temperatūroje skyla nesilydydama. Netirpsta įprastiniuose organiniuose tirpikliuose, silpnai brinksta metanolyje, acetone, dichloretane. Vandenyje kambario temperatūroje ištirpsta iki 0,3 g/1, tirpumas priklauso nuo polimero molekulinės masės (2 lentelė) - jai didėjant tirpumas mažėja. Ištirpinus aukštesnėje temperatūroje ir po to aušinant gaunami persotinti tirpalai, kurie lėtai drumsčiasi laike dienų ar savaičių. Prototipo - polidimetildialilamonio chlorido tirpumas yra begalinis, išdžiovintas jis godžiai sorbuoja .drėgmę, o tirpalai maišosi su vandeniu bet kokiais santykiais.The polydimethyldiallylammonium iodide obtained by the exchange reaction is a white fine dispersion amorphous substance. Decomposes without melting at 240-260 ° C. Insoluble in common organic solvents, slightly swellable in methanol, acetone, dichloroethane. Dissolves in water at room temperature up to 0.3 g / l, solubility dependent on molecular weight of polymer (Table 2), decreasing with increasing solubility. Dissolving at a higher temperature and then cooling gives saturated solutions that slowly cloud over time for days or weeks. The prototype - polydimethyldiallyl ammonium chloride has infinite solubility, when dried, it greedily absorbs moisture, and the solutions are miscible with water in any ratio.
Jodo sorbcija polidimetildialilamonio jodidu taip pat priklauso nuo polimero molekulinės masės ir yra labai didelė - siekia 200% nuo jo masės. Tai patvirtina 3 lentelėje pateikti duomenys. Išlaikius PDMDAAJ miltelius uždarame inde jodu prisotintame ore (virš jodo kristalų), jų spalva kinta nuo baltos iki tamsiai rudos ir galiausiai mėlynai juodos, padidėja jų masė. Tai rodo, kad ši medžiaga gali sorbuoti jodą ir iš dujų fazės.The sorption of iodine with polydimethyldiallyl ammonium iodide is also dependent on the molecular weight of the polymer and is very high, up to 200% by weight. This is supported by the data in Table 3. The PDMDAAJ powder, when kept in a sealed container in iodine-saturated air (above the iodine crystals), changes color from white to dark brown and eventually blue to black, increasing in weight. This indicates that this material can also adsorb iodine from the gas phase.

Siūlomas jodą sorbuojančios medžiagos, polidimetildialilamonio jodido, gavimo būdas realizuojamas taip: į vandeninį PDMDAACI tirpalą maišant pilamas vandeninis neorganinio jodido (KI, NaI) tirpalas, esant veikliųjų medžiagų moliniam santykiui.l:l ir atskiriamos iškritusios nuosėdos. Kalio jodido atveju šis santykis atitinka ir masių santykį 1:1 (g-ekv PDMDAACI=162, g-ekv KI=166).The proposed process for the preparation of an iodine sorbent, polydimethyldiallyl ammonium iodide, is carried out as follows: an aqueous solution of inorganic iodide (KI, NaI) is added to the aqueous solution of PDMDAACI in a molar ratio of the active ingredients. In the case of potassium iodide, this ratio also corresponds to a weight ratio of 1: 1 (g-eq PDMDAACI = 162, g-eq KI = 166).
