Synthesis of polyaramids in γ-valerolactone-based organic electrolyte solutions

synthesis of 3-aryl-2h-benzo[b]-1,4-oxazines in [omim]bf4 and reduction of organic compounds in methylimidazolium formate

در این پروژه ترکیبات 3-آریل-2h-بنزو[b]-4،1-اکسازین ها از مواد اولیه تجاری مشتقات دو آمینو فنول و ?-هالو کتون های آروماتیک در مایع یونی 1-اکتیل-3-متیل ایمیدازولیوم تترا فلورو بورات([omim]bf4) سنتز شده است. این واکنش توسط باز پتاسیم کربنات محلول از طریق o-آلکیلاسیون و سپس یک واکنش آمیداسیون درون مولکولی خود بخود در مدت زمان کوتاه انجام می شود. ترکیبات 4،1-بنزوکسازین به این روش با بهره خوب تا آلی ...

Acet­oxy-γ-valerolactone

Levulinyl cellulose esters have been produced as an effective renewable binder for architectural coatings. The title compound, C7H10O4 (systematic name: 2-methyl-5-oxo-tetra-hydro-furan-2-yl acetate), assigned as the esterifying species, was isolated and crystallized to confirm the structure. In the crystal, the mol-ecules pack in layers parallel to (102) utilizing weak C-H⋯O inter-actions.

Instantaneous dissolution of cellulose in organic electrolyte solutions.

Herein a novel class of solvent systems for cellulose is introduced. Surprisingly, organic electrolyte solutions, which contain just a small molar fraction of ionic liquid, dissolve instantaneously large amounts of cellulose. The solvation properties of the solvent systems, required for dissolving the polymer, are discussed here.
