“…The main part of researches is devoted to epoxidized soybean oil (ESBO) carbonation [6][7][8][9][10][11][12], in some works the epoxidized linseed oil (ELSO) [5,13] is used. Such choice is defined by the availability of these oils which are large-capacity products [14], they are widely applied at halogenated polymers processing (for example, polyvinylchloride).…”

“…Successful application of potassium iodide to receive CCVO is possible only in case of its activation by 18-krown-6 ether [8]. Heterogeneous catalytic system (silica-supported 4-pyrrolidinopyridinium iodide on SiO 2 (SiO 2 -I) [13] which has well proved in the process of propylene oxides and styrole carbonation [16], has appeared not so successful for CCVO synthesis.…”

“…The first work on the receiving of CCVO was carried out at the atmospheric pressure [6] in 2004. In the following years the carbonation of epoxidized oils at the atmospheric pressure was carried out by a number of researchers [5][6][7][8][9]13], who noted a considerable period of time (as a rule, some days) necessary for the achievement of high values of EG oil conversion, and the fast growth of viscosity in the process of carbonation.…”

The analysis of literary data on the obtaining of cyclic carbonates based on the vegetable oils has been carried out. The influence on carbonation reaction the type of vegetable oil, the chemical composition and catalyst concentration, state of carbon dioxide, pressure and temperature have thus been considered. The carbonation process of epoxidized oils that are valuable renewable vegetable raw materials is studied insufficiently.

“…Today, several environment friendly routes for the production of PU have cropped up. Research has been focussed on the preparation of PU from non-isocyanate routes, and also on the use of fatty acid based isocyanates for PU production, considering the persisting challenges of polymer industry and immediate attention sought towards environmentally benign chemicals and chemical routes for the same [9][10][11][12][13][14][15][16][17][18].…”

Resumo:No presente trabalho, utilizou-se a calorimetria diferencial exploratória (DSC) para investigar a cinética da reação de cura de resinas epóxi produzidas a partir da reação do óleo de soja epoxidado (ESO), com os anidridos dodecenilsuccínico (DDS), maleico (MAL), ftálico (FTA), succínico (SUC) e hexahidroftálico (CH), atuando como agentes de cura, e na presença de aminas terciárias como a trietilamina (TEA), a N,N'-dimetilanilina (ARO) e a 1,4-diazobiciclo[2,2,2]octano (DABCO), atuando como catalisadores. A taxa de aquecimento, a natureza química e a estrutura do anidrido e das aminas influenciaram a reação de cura. Os métodos dinâmicos de Kissinger, Ozawa e de Barrett foram utilizados para calcular a energia de ativação dos sistemas onde se variou o anidrido. Observou-se que os anidridos mais reativos foram o DDS e maleico que apresentaram os menores valores de energias de ativação. No estudo da influência do catalisador, utilizou-se o método de Barrett para determinar as energias de ativação das reações com as diferentes aminas. A amina cicloaliafática (DABCO) foi a mais reativa obtendo-se o menor valor de energia de ativação (Ea = 51 kJ.mol -1 ) e fator pré-exponencial (ln A 0 = 9 s -1 ). Palavras-chave: DSC, óleo de soja epoxidado, resina epóxi, estudo cinético. Investigation of the Kinetics of Cure by Differential Scanning Calorimetry (DSC) of Epoxy Resins Prepared from Epoxidized Soybean Oil with Different Anhydrides and Tertiary AminesAbstract: In the present work, differential scanning calorimetry (DSC) was used to investigate the curing reaction kinetics of epoxy resins produced from reaction of epoxidized soybean oil (ESO) with cyclic anhydrides dodecenylsuccinic (DDS), maleic (MAL), phthalic (PA), succinic (SUC) and hexahydrophthalic (CH), in the presence of tertiary amines such as triethylamine (TEA), N,N-dimethylaniline (ARO) and 1,4-diazabicyclo[2,2,2]octane (DABCO). The heating rate, the nature and structure of anhydrides and amines were found to affect the curing reaction. The dynamic methods of Kissinger, Ozawa and Barrett were used to calculate the activation energy of the reactions where different anhydrides were used. DDS and maleic anhydrides were more reactive than the others. In studying the influence from the catalyst, we used the Barret's method to determine the activation energy of the reactions. The 1,4-diazabicyclo[2,2,2]octane amine (DABCO) was the most reactive, showing the lowest activation energy (Ea= 51 kJ.mol -1 ) and pre-exponential factor (ln A 0 = 9 s -1 ). Keywords: DSC, epoxidized soybean oil, epoxy resin, kinetic study. IntroduçãoAs resinas epóxi fazem parte de uma das mais importantes classes de polímeros termofixos. As inúmeras formas de processamento tornam possível a sua aplicação em diversos segmentos industriais tais como: tintas, adesivos, revestimentos e como matrizes de compósitos devido a suas propriedades químicas e físicas [1][2][3][4] . Estas resinas têm boas propriedades térmicas, elétricas e mecânicas, embora sejam frágeis e apresentem baixa resistênci...
