The multi-component condensation of chalcones, malononitrile, alkylhalides, hydrogen sulphide and N-methyl-morpholine completes with forming 2-alkylsulphanil-4,6-diarylpyridine-3-carbonitriles, which are used in the synthesis of the substituted 1,4-bis(3-... see more

This article presents an excerpt from a theory of lexicographic texts which deals particularly with dictionary articles. Almost all characteristics of dictionary articles considered as typically lexicographic may be regarded as results of textual condensa... see more

Alkylation of 3-aryl-4,6-dimethoxyindole 3a and 3b with methyl and ethyl a-bromoacetates afforded good yields of indol-1-ylacetates 4. Treatment of these indoles 4 with the Vilsmeier formylation reagent gave formylindoles 5 in 54-81 % yield. These formyli... see more

In this study, an efficient and generally applicable 2nd generation sol – gel entrapment method was developed for immobilization of yeastcells. Cells of Lodderomyces elongisporus, Candida norvegica, Debaryomyces fabryi, Pichia carsonii strains i... see more

Cet article présente une analyse expérimentale en régime transitoire d’un écoulement de vapeur d’eau en condensation dans un seul microcanal. Différents  régimes d’écoulement sont identifiés. on a abordé cette étude expérimentale par  la visuali... see more

Sequential condensation and hydrodeoxygenation reaction were perform using autoclave batch reactor in the presence of water as a solvent. The condensation of furfural and acetone was performed using MgO catalyst followed by hydrodeoxygenation using mix ca... see more

Aluminium chloride immobilized on mesoporous aluminosilicate was investigated as catalysts in the condensation of isatin with indole. AlCl3/mesoporous aluminosilicate (AlCl3/AM) catalysts were prepared by impregnation of 1, 5, 10 and 15 wt% AlCl3 on the s... see more

This research aims to synthesis liquid alkanes from biomass-derived hydroxyl methyl furfural (HMF) and furfural by aldol-condensation and hydrogenation processes over several catalysts i.e. TiO2, TiO2-ZrO2, Pd/Al2O3 and Pd/CeO2. It was found that the cata... see more

The article presents the calculation of heat transfer coefficient during condensation of steam, the mathematical model of temperature distribution in the gas and liquid phases of the coolant and the model of the formation of the condensate film on the wal... see more
