Organic Synthesis and Polarography

Recent Trends in Organic Polarography

INTRODUCTION The present paper does not attempt to be exhaustive in listing all of the current trends in the polarography of organic compounds. Rather, an attempt has been made to focus attention on those trends, which seem of major importance for future studies in organic polarography, with particular reference to some of the unsolved problems which still confront us. Significant recent activi...

Application of Oscillographic Polarography to Determinationof Organic Phosphorus Pesticide Residues

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 ...

Polarography in Molten Salts

TYPES OF MELTS From the practical viewpoint, melts may be classified according to melting points which may limit the available techniques. The lowest melting, with working temperatures up to 250°, are typified by the LiNO3—NaNO3— KNO3 eutectic, NaNO3—KNO3 eutectic, LiClO4, and ammonium formate. With these solvents it is possible to use the dropping mercury electrode, or hanging mercury drop ele...

Polarography of diacetylthiamine and dibenzoylthiamine.

In recent years, a series of thiamine derivatives has been synthesized and many investigations have been made both chemically and medically. Allithiamine, a S-alkyl thiamine derivative, was studied in the previous pa per (1) and was found to have polarographically a similar behavior to thia mine. In the present experiment, polarographic investigations on diacetyl thiamine (DAT) and dibenzoylthi...
