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 اولDetermination of organic iodine compounds in serum. II. Chromatographic studies of exogenous organic iodine compounds affecting the PBI and BEI.
R1_ values of organic iodine compounds which interfere with the determination of serum protein-bound iodine (P81) and butanol-extractable iodine (BEI) levels were obtained for the solvent system 2-butanol-4% NH4OH (3:1) utilizing descending paper chromatography. The feasibility of employing this system for identification of exogenous organic iodine in patients’ sera was investigated. In general...
متن کاملUltramicro determination of chloride.
A simple technique has been described by Wigglesworth (1937) for the determination of chloride in as little as 0-3 ,ul. of fluid. This is based on the Volhard titration and has been used in this Laboratory since 1947 for the examination of fish and crustacean blood. While the results obtained were satisfactory, the tedious back titration and the comparatively impermanent end point were found to...
متن کاملPotentiometric Determination of Acidity Constants of Some Synthesized Organic Compounds in Organic-Water Media
The acidity constants of some synthesized protonated pyrazolo quinazoline compounds were determined potentiometrically at ionic strength of 0.1 M in DMF: water (60:40 v/v) system at different temperatures (298.15 K to 318.15 K). The pKa values have been found to increase with increasing electron-donating nature of substitutions. Some thermodynamics parameters such as enthalpy (ΔH°), Gibb’s free...
متن کاملDetermination of iodine and bromine compounds by ion chromatography/dynamic reaction cell inductively coupled plasma mass spectrometry.
An inductively coupled plasma mass spectrometer (ICP-MS) was used as an ion chromatographic detector for the speciation of iodine and bromine. Gradient elution using NH4NO3 at pH 10 allowed the chromatographic separation of ionic iodine (I- and IO3-) and bromine (Br- and BrO3-) species in less than 8 min. Effluents from the ion-exchange column were delivered to the nebulization system of ICP-MS...
