Design and synthesis of new symmetrical Schiff bases
A series of symmetric multidentate Schiff base ligands 1–13 based on the N‚N′-4‚4′-ethylenebiphenylbis-3-methoxysalicylideneimine for used to bind various transition metals detection of K, AgI‚ CuII, Sr II Co II and NiII at trace levels in real-world samples has been synthesized purified and their structures was characterized.
متن کاملStudy the Voltammetric Behavior of Symmetrical Tetradentate Schiff Bases
Accepted on 25 th August 2014 _____________________________________________________________________________ ABSTRACT Synthesis of symmetrical Schiff bases (1-4) employed by using condensation methods. Purity was monitored by TLC and column chromatographic techniques. In this present study cyclic voltammetric behavior of symmetrical Schiff bases (1-4) were studied. The cyclic voltammetric studie...
متن کاملRestricted methods in symmetrical linear regression models
In this paper we discuss the problem of testing equality and inequality constraints in symmetrical linear regression models. This class of models includes all symmetric continuous distributions, such as normal, Student-t, Pearson VII, power exponential and logistic, among others. It is commonly used for the analysis of data containing influential or outlying observations with responses supposed...
متن کاملInduction of symmetrical nucleus division and multi-nuclear structures in isolated microspores of sugarcane (Saccharum officinarum L.)
In this study, the effects of floret sterilization with sodium hypochlorite, cold stress, heat shock, 2,4-dichlorophenoxyacetic acid and colchicine treatment on microspore viability and induction of symmetrical nuclei divisions were assessed in six genotypes of sugarcane. The highest microspore viability was observed when florets were sterilized with 3.0% and 3.5% sodium hypochlorite in all gen...
متن کاملsynthesis and characterization of some macrocyclic schiff bases
ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...
