Green Chemistry: Terminology and Principles

Magnetic nanoparticle-supported imidazole tribromide: a green, mild, recyclable and metal-free catalyst for the oxidation of sulfides to sulfoxides in the presence of aqueous hydrogen peroxide

“…[1][2][3] Materials chemistry has made two important steps during the last few decades with the introduction and development of nanoparticles 4-6 on the one hand and ionic liquids (ILs) 7 on the other hand.

More Than a Scientific Movement

“…Matus (2009) provided a comparison between barriers to GC in the U.S., China and to some extent in India. The political background presumably infl uences the defi nition given to GC, in particular in a context of debates around policies on chemical risks (Wilson and Schwarzman, 2009a;O'Brien et al, 2009;Iles, 2011).…”

“…Few explanations have been attempted in the social sciences, among which the most coherent was published by Woodhouse & Breyman (2005), who described it as a social movement. Other research 1 has acknowledged a wide variety of meanings given to the term GC, diff ering in their relative scientifi c versus political content (Schwarzman and Wilson, 2009;Schwarzman, 2009a, 2009b;O'Brien et al 2009;Iles, 2011) and in the research activities and knowledge areas included (Sjöstrom, 2006;Maxim, 2011a). Accounting for this diversity, Sjöstrom (2006) proposed two models for under-standing GC: a classification model of different green chemistry activities (research activities, management activities and policy activities), and a second model concerning green chemistry policy and knowledge areas (green chemistry principles, industrial biotechnology and the "green sector,'' i.e., agriculture and forestry).…”

The debate about what exactly constitutes research in GC spans a continuum from GC as a new scientifi c discipline within the fi eld of chemistry (O'Brien et al, 2009), a science (O'Brien et al, 2009), a meta-discipline covering most of chemistry and chemical engineering (Sjöstrom, 2006), or a philosophical approach that underpins chemistry (Wilson and Schwarzman, 2009b;Llored, 2012;Bensaude-Vincent, 2013), to broader approaches including chemical risk policies (Iles, 2011) and all activities aiming at greening chemistry (Sjöstrom, 2006). The term itself seems to respond to a variety of research areas and objectives, which might explain its academic success, measured by the continuously increasing number of publications using it (Linthorst, 2010;Epicoco et al, 2012).…”

Desenvolvimento de novas combinações monômero - catalisador para a produção de polímeros via ROMP

“…Neste contexto, é de suma importância que a síntese e modificação de novos compostos ocorram de maneira eficiente, com alta produtividade e baixo custo de produção. Além disso, a preocupação global com meio ambiente impõe fatores nesta conta, como a geração de pouco ou nenhum resíduo, uso de substâncias atóxicas entre outros fatores, os quais são fundamentos da "Química Verde" [13] .…”
