چکیده
The expansion of catalytic methods is a focus of contemporary interest due to the adverse effects of the manufacturing process of fine chemicals, pharmaceuticals, and materials on the environment. According to the green chemistry principles [۱], the “green” catalyst is the one that can be simply removed from the reaction mixture and reused. In this field, magnetic nanoparticles have been the focus of great attention as a magnetically separable matrix for catalysts [۲].Also, it is clear that green chemistry not only requires the use of “green” catalyst but also development of solvent-free reactions is one of the most important research threads in greenchemistry. Solvent-free conditions have advantages, such as simple reactors, easy work-up procedures, short reaction times and environmentally benignancy [۳, ۴].The present paper explains that this approach allowed us to prepare the most active heterogeneous vanadium catalysts for the selective acetylation of alcohols .The paper also addresses a few important and interesting aspects of the catalytic reaction such as activity and selectivity for various substituents at the alcohols; also, recovery and reuse of the catalyst.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
