Abstract

Production of new types of effective and green softeners for polyvinylchloride (PVC) is one of the important concerns in chemical industry. The paper reports results of investigations on obtaining symmetric esters of a series of fatty acids and triethylene glycol (TEG) and their use as effective PVC plasticizing agents. The esterification process was conducted in the presence of nano-grade titanium dioxide Degussa P-25 and specified by environmentally sound technology. Good compatibility and low volatility of the bio-based type esters in PVC formulations were shown and higher physico-mechanical features of the PVC composites were established. The esters may be recommended as effective and environmentally friendly PVC softeners to replace commonly used phthalates.

Kurzfassung

Die Produktion von neuen effektiven und „grünen“ Weichmachern für Polyvinylchlorid (PVC) stellt eine der großen Herausforderungen in der chemischen Industrie dar. In diesem Beitrag wird über Ergebnisse von Untersuchungen berichtet, in denen symmetrische Ester einer Reihe von Fettsäuren und Triethylenglykol (TEG) gewonnen wurden und die als effektive Plastifizierungskomponenten verwendet wurden. Die Veresterung wurde unter Zugabe von Titandioxid Degussa P-25 in Nanopartikelgröße als umweltverträgliche Technologie durchgeführt. Eine gute Verträglichkeit und eine niedrige Flüchtigkeit der Ester auf Biobasis in den PVC-Rezepturen werden gezeigt und es konnten bessere physiko-mechanische Eigenschaften der PVC-Komposite eingestellt werden. Die Ester können als effektive und umweltfreundliche PVC-Weichmacher und als Ersatz für herkömmliche Phtalate empfohlen werden.

Prof. Dr. sc. nat. Eldar B. Zeynalov studied chemistry at the Azerbaijan State University, Baku (1966–1971). From 1971 to 1976 he was post-graduate student and Candidate of Chemical Sciences (Candidate = Dr. rer. nat. = PhD) at the Institute of Chemical Physics of the USSR Academy of Sciences, Moscow. Between 1976 and 1989, he was research officer, senior staff scientist, assistant professor and associate professor. Doctor of Chemical Sciences (Dr. sc. nat. = Dr. rer. nat. habil.) (1989), full professor (2010) and head of scientific departments and laboratories (1991 – present) at different institutes of the Azerbaijan Academy of Sciences, Baku.

Shahnaz N. Maherramova graduated from the Baku State University in 2006. She acquired her Master´s degree at the Sumgayit State University in 2009. Since 2006 she is chemist at the laboratory of “Hydrocarbons Liquid Phase Oxidation” of the IPCP ANAS.

Dr. PhD Nazilya F. Sadieva graduated the Azerbaijan State University in 1981, achieved her PhD in chemistry at the IPCP of ANAS in 2008. Since 1981 she has been working in the laboratory of “Hydrocarbons Liquid Phase Oxidation” of the IPCP ANAS as junior researcher and now she is senior researcher.

Dr. PhD Sevil A. Iskenderova graduated from the Azerbaijan State University in 1964, achieved her PhD in Chemistry at the Institute of Petrochemical Processes (IPCP) in 1971. Since 1962 she has been working at the laboratory of “Hydrocarbons Liquid Phase Oxidation” of the IPCP of Azerbaijan National Academy of Sciences (ANAS) as research officer, senior staff scientist and now she is in position of leading research scientist.

Dr. PhD Bahadur K. Agayev studied chemistry at the Azerbaijan Pedagogical Institute, Baku (1968–1973). He was conferred by PhD scientific degree in 1983. Since 1978 he has been working at the IPCP ANAS in postions of research officer, senior staff scientist, leading researcher and assistant professor.

Prof. Dr. rer. nat. habil. Joerg F. Friedrich studied chemistry at the Humboldt University, Berlin, Germany. 1975 he acquired the Dr. rer. nat. (PhD) in Polymer Chemistry from the Academy of Sciences of GDR, Institute of Macromolecular Sciences, Berlin, as well as the Promotion B (Habilitation).1982 he became Dr. sc. nat. in polymer and plasma chemistry. Ordinary habilitation (Dr. rer. nat. habil.) followed in 1991 from the TH Merseburg. Since 1996 he is Director and Professor at the Federal Institute for Materials Research and Testing, as well as Professor at the Technical University Berlin (2007).
