  Otimização de processos químicos: Papel de solventes verdes e suas misturas, Descrição: Os objetivos específicos do presente projeto são: 1- Investigar detalhes de solvatação por solventes e suas misturas binárias a diferentes temperaturas. Este estudo envolve propriedades macroscópicas (viscosidade) e microscópicas (polaridade, acidez e basicidade de Lewis, dipolaridade e polarizabilidade). Esta parte será realizado com o auxílio de sondas solvatocromicas (substancias cujos espectros são bastante sensíveis as propriedades do meio). 2- Otimização de reações de transferência de acila e de substituição nucleofílica pelo uso racional de solventes e suas misturas. As primeiras são quimi-luminescentes e visam aumentar o rendimento quântico pela supressão da reação secundária de hidrólise. As demais visam otimizar a síntese de LIs. 3- Síntese controlada de derivados bifuncionais de celulose, incluindo ésteres mistos de celulose (carboxilatos alifático/aromático), carboxilato/sulfato; carboxilato/ carbometóxi (éster/éter). 4- Aplicação dos derivados de celulose obtidos na etapa 3 em: imobilização de lipase e testes da atividade enzimática; formação de nanofibras por eletrofiação; formação de compósitas de celulose e seus derivados.. , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (4) / Especialização: (1) / Mestrado acadêmico: (1) / Doutorado: (2) . , Integrantes: Omar Abou El Seoud - Coordenador / Paulo Augusto Rodrigues Pires - Integrante.

  Biopolímeros Modificados: Derivatização de de celulose sob condições homogêneas, Descrição: Estamos interessados na síntese de biopolímeros funcionalizados, em particular ésteres, ésteres mistos, e éteres de celulose sob condições homogêneas de reação. Os solventes empregados são sistemas clássicos (LiCl/N,N-dimetilacetamida, LiCl/DMAc; fluoreto de tetra-n-butil- amônio./DMSO, TBAF/DMSO), e líquidos iônicos; LIs. Embora este esquema de reação ofereça uma série de vantagens em relação ao processo industrial (heterogêneo) é mais complexo e de custo mais elevado. Conseqüentemente, nosso interesse está na simplificação e otimização das três etapas deste esquema, a saber: ativação da celulose, sua dissolução e reação com o agente acilante. Os pontos que estão sendo investigados incluem: (i) Otimizar o uso de solventes clássicos e LIs na funcionalização de celulose; (ii) Investigar os efeitos das características estruturais da celulose, em particular grau de polimerização, GP, índice de cristalinidade, Ic, e estrutura supra-molecular sob as condições necessárias para sua derivatização; (iii) Investigar as propriedades e aplicações dos produtos obtidos.. , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (0) / Especialização: (0) / Mestrado acadêmico: (0) / Mestrado profissional: (0) / Doutorado: (1) . , Integrantes: Omar Abou El Seoud - Integrante / P A R PIRES - Integrante / SHIRLEY POSSIDONIO - Integrante / L C Fidale - Coordenador / Tomas Heinze - Integrante / A Koschella - Integrante., Financiador(es): Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - Cooperação / Fundação de Amparo à Pesquisa do Estado de São Paulo - Auxílio financeiro.

  Síntese, Propriedades e Aplicações de Tensoativos e Bio-Polímeros Funcionalizados: Um Enfoque de Química Verde, Descrição: O projeto compreende dois subprojetos sobre tensoativos e funcionalização de celulose. O primeiro incluí: Síntese de tensoativos que possuem grupos hidrofílicos e hidrofóbicos variáveis, inclusive tensoativos ?verdes?; Investigação da relação entre a estrutura de tensoativo e as propriedades de suas soluções aquosas e não aquosas; Determinação da polaridade microscópica e estrutura de solventes ?verdes?, suas misturas binárias, e de água interfacial de agregados micelares; Investigação do uso de tensoativos clássicos e verdes como catalisadores de reações orgânicas. Usando diversas técnicas, serão estudados os efeitos da estrutura de tensoativo sobre as seguintes propriedades dos agregados formados: concentração micelar crítica; grau de dissociação do contra-íon de tensoativo; número de agregação; morfologia micelar, e parâmetros termodinâmicos de adsorção e micelização. Usando sondas solvatocrômicas, pretende-se investigar os efeitos da estrutura e carga de tensoativos sobre a polaridade microscópica e concentração ?efetiva? de água interfacial. Na parte de catálise pretende-se estudar a cinética de reações de transferência de acila, de ésteres em soluções de tensoativos clássicos e verdes. No subprojeto sobre bio-polímeros funcionalizados, pretende-se estudar a derivatização de diversas celuloses (micro-cristalina, cisal, algodão) sob condições homogêneas de reação. Os estudos previstos visam aperfeiçoar as três etapas do processo: ativação da celulose, dissolução do polímero ativado, e subseqüente derivatização. Pretende-se investigar a relação entre as características estruturais da celulose e as condições de sua derivatização. Tais características incluem o grau de polimerização, o índice de cristalinidade, a porosidade e a polaridade da superfície do polímero. Pretende-se empregar LiCl/DMAc e (n-C4H9)4NF.3H 2O/DMSO como sistemas de solventes, a fim de verificar a eficiência de ambos na dissolução destas celuloses.. , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (0) / Especialização: (0) / Mestrado acadêmico: (0) / Mestrado profissional: (0) / Doutorado: (0) . , Integrantes: Omar Abou El Seoud - Coordenador / E FROLLINI - Integrante / J W Baader - Integrante., Financiador(es): Fundação de Amparo à Pesquisa do Estado de São Paulo - Auxílio financeiro.
