Аннотация

Subjects of research: the objects of research chose sulfate of aniline a waste leather process industries received of polyaniline from this withdrawal (waste), polyacapramid, weak polyacids and bentonets of Nurata mountain range of our Republic. Purpose of work: the purpose dissertation work is the research of physicchemical properties, revealing of mechanisms both laws of interaction polyanilines and polyacids, on their basis to develop of effective structures and technology of reception new composite polymeric sorbents, study of their physic- chemical and operational properties and to develop the recommendations till their industrial application. Methods of research: study kinetic dope ration of polyaniline of formation (education) of polymer-polymeric complexes with use of polyacids and polymeric composition on their basis. Research of physic- chemical properties were carried out optical, ultra- violet, infra- red spectrum, nucleus- magnetic resonant, electroparamagnet resonant, gilpronic khronomotograph, rayon, potensial thitrovan, thermogravimetre, electrical- scanning to methods. The results obtained and their novelty: -law of formation (education) of polyaniline from sulfate of aniline being a withdrawal (waste) leather process of an industry under influence of the initiator persulfate ammonium for the first time is established at temperature of reactionary environment (Wednesday) 5-7; -for the time established energy of activation of reaction dehidrochloric dope ration of polyaniline and polymer of polymeric complete sets polyaniline with polyacids. Are revealed kinetical of dependence of quantity (amount) of current proceeding though a tablet of polyaniline from time dope ration. Using the equations With. Arrenius energy of activation of process dehidrochloric of polyaniline which for the first time is determined, makes 26,4 kDj/mol; -the influence ion of force and molecular weight of half-aniline on speed of formation (education) of polymer-polymeric complexes with made polyacriline by acid established. The products are capable such polymer-polymeric reaction swell in water and effectively sort ions from water solutions. At immersing polymerpolymeric hudrogile in water solution grateful and heavy metals, proceeds effective sorbsion of ions of these metals of ions these of metals with education threefold polymer of a metal complex; -the realization of complex researches of physic-chemical properties and structures polyaniline from sulfate of aniline being a withdrawal (waste) leather process of an industry and their complexes with polyacids UF,IK, YaMR, EPR- spectrum, potential metric, electron scanning by microscopic methods establishes laws of interaction and formation (education) polymer-polymeric complexes for account beaten of atoms of nitrogen in circuit of polyaniline and formation (education) of hydrogen communications (connections) between macromolecule of polyaniline both polyacids and creation effective composite polymeric sorbents on their basis for clearing departing gases the industrial enterprise. Practical value: for application created and received composite sorbents is developed and the skilled installation nasad micro cummilation for clearing departing harmful gases is made and their skilled tests are carried out (spent). Application developed composite polymeric sorbents for clearing gases in shop of manufacture of a nitric acid on а ОАО “Navoi Nitrogen” have resulted to uproshneniyu of technological process of clearing of departing gases and economy platino-podiyevogo of the catalyst. Degree of embed and economic effectivity: the tests polymer-polymeric sorbents developed on the basis of polymer-polymeric complexes carried out (spent) on Navoiyscom an Electrochemical factory and ОАО “Navoiazot” have shown high economic and waste water from harmful impurity. On the OAS “Navoi Nitrogen” from introduction developed sorbents the expected economic benefit makes more than 1215230 t sums per one year 2007. Field of application: the enterprises NXK “UZ.chim.industry”, state committee on protection environmental (Wednesdays) clearing of departing gases and source of from gases, harmful to an environment and impurity.
