synthesis 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...
15 صفحه اولInvestigating the Bio-corrosion Inhibition Effect of Enzymes in Circulating Cooling Water System
To avoid the secondary pollution that inorganic corrosion inhibitor may cause in circulating cooling water, the bio-corrosion inhibition effect of lysozyme, catalase, lipase, and laccase, as the biologic inhibitors without the above problem, and the increased bio-corrosion inhibition effect of Ca+2 and Mg+2 are studied. An enzyme with corrosion properties was selected by rotary coupon test. The...
متن کاملSynthesis of biologically active novel bis Schiff bases, bis hydrazone and bis guanidine derivatives
A number of bis Schiff′s bases 3a-d have been synthesized by condensation of 2,4,8,10 tetraoxaspiro[5,5]undecane 3,9dipropanamine 1 with furfural, indole-3-aldehyde, 2-acetylpyridine, 4-acetylpyridine and 5a-c by condensation of 1,4-bis (3-aminopropyl) piperazine 4 with indole-3-aldehyde, 2-acetylpyridine, 4-acetylpyridine, in high yields by using microwave irradiation. Bis hydrazone derivative...
متن کاملSynthesis, Characterization and Biological Evaluation of Schiff Bases of Propanedihydrazide
A Schiff base series of malonohydrazide was synthesized by reaction of malonohydrazide with various aldehydes. Hydrazine hydrate was reacted with ethyl malonate in ethanol to give malonohydrazide in very good yields. The synthesized compounds were characterized using FTIR and NMR spectroscopies. The biological evaluation of the Schiff bases was carried against Gram +tive and Gram –tive bacteria...
