Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is very useful for the researcher and academia who are working on Pyrimidine derivatives. This book deals with spectroscopic characterization of synthesized pyrimidines. This books contain one separate chapter for antimicrobal activity. All synthesized compounds were tested for their microbial screening. The synthesis of chalcones was carried out by one pot condensation of 1-chloro-(4-tolyloxy) benzene with 1-(4-hydroxylphenyl) ethanone followed by condensation with various aromatic aldehydes. Prepared chalcones were refluxing with guanidine to yields various pyrimidine derivatives. All the prepared compounds were characterized in by 1H NMR, 13C NMR, IR, MASS spectroscopic techniques. Biological evaluation of mention compounds was also made in terms of gram positive bacteria such as Staphylococcus aureus, Bacillus megaterium and gram negative bacteria Escherichia coli, Proteus vulgaris. 56 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -High yielding, one pot protocol for the synthesis of 2-substituted benzimidazole and benzoxazole derivatives from readily available o-phenylenediamines/ o-aminophenol and aromatic aldehydes, under microwave and convenient conditions has been developed. The conditions are mild. A wide range of functional groups can be tolerated by the protocol. ENPFSA as catalyst offers advantages including simplicity of operation, easy workup, high yields with excellent purity, short reaction time and the recyclability of the catalyst 76 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book gives idea about how to modified reactive functional group Polymer structure using acidic substrate. Book represents the Applications of different heterogeneous catalyst with their selectivity and specificity. Synthesis of novolac phenol formaldehyde resin (NPFR) from formaldehyde and phenol is covered and Synthesis of epoxy novolac phenol formaldehyde resin (ENPFR) from NPFR by epoxidation using NaOH and epichlorohydrine and their modification with sulphanilic acid to from ENPFSA are discuss well. Characterization of NPFR, ENPFR and ENPFSA by IR spectroscopy, Functional group analysis, Thermo Gravimetric Analysis (TGA) for the decomposition temperature and degradation pattern are made well. Selectivity and specificity of catalyst is discuss well with suitable examples of organic substrate with more than one functionality. Catalyst stability comparison using thermogravimetric data is discuss well. 76 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Jeta kniga ochen' polezna dlq issledowatelej i uchenyh, kotorye rabotaüt nad proizwodnymi pirimidina. V knige rassmatriwaetsq spektroskopicheskaq harakteristika sintezirowannyh pirimidinow. Jeta kniga soderzhit otdel'nuü glawu po antimikrobnoj aktiwnosti. Vse sintezirowannye soedineniq byli protestirowany na mikrobnyj skrining. Sintez halkonow byl osuschestwlen putem odnopotochnoj kondensacii 1-hlor-(4-toliloxi) benzola s 1-(4-gidroxilfenil) ätanonom s posleduüschej kondensaciej s razlichnymi aromaticheskimi al'degidami. Podgotowlennye hal'kony byli proreflüxirowany s guanidinom s polucheniem razlichnyh proizwodnyh pirimidina. Vse prigotowlennye soedineniq byli oharakterizowany s pomosch'ü 1N YaMR, 13S YaMR, IK, MASS spektroskopicheskih metodow. Biologicheskaq ocenka upomqnutyh soedinenij byla takzhe prowedena w otnoshenii grampolozhitel'nyh bakterij, takih kak Staphylococcus aureus, Bacillus megaterium i grampolozhitel'nyh bakterij Escherichia coli, Proteus vulgaris. 56 pp. Russisch.…
