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 ...
15 صفحه اولOrganic ammonium salts. VII.* Preparation and infrared spectra of some ammonium derivatives of 11-aminoundecanoic acid
When studying some organic ammonium salts as potential solubilizers [1—4] we found that they possessed good surface-active properties as well as significant antimicrobial activity. The assumption of favourable relationship between the effect of the ammonium group and the properties of the alkanecarboxylic acid and of its esters, respectively, prompted us to prepare the title compounds and study...
متن کاملPhysical properties of ambient and laboratory- generated secondary organic aerosol
The size and thickness of organic aerosol particles collected by impaction in five field campaigns were compared to those of laboratory-generated secondary organic aerosols (SOA). Scanning transmission X-raymicroscopy was used tomeasure the total carbon absorbance (TCA) by individual particles as a function of their projection areas on the substrate. Particles with higher viscosity/surface tens...
متن کاملSources of organic carbon in PM1 in Helsinki urban air
A major fraction of fine particle matter consists of organic carbon (OC) but its origin is still inadequately known. In this study the sources of OC were investigated in the northern European urban environment in Helsinki, Finland. Measurements were carried out over one year and they included both filter (PM 1) and online methods. From 5 the filter samples OC, elemental carbon (EC), water-solub...
