A convenient method for the obtaining of 3,6-diaryl-1,2,4-triazines substituted with  residues of higher alcohols in the position of C5 via the ipso-substitution of cyano group in under the solvent free conditions was reported. This method indicates ... see more

Electrooxidation of N,N’-diphenylguanidine (1,3-diphenylguanidine) was investigated in aprotic (acetonitrile, acetone, dimethyl sulfoxide, dimethyl formamide, propyleneoxide, nitromethane) and alcoholic (methanol, ethanol, 1-propanol, 1-butanol, 1-pentano... see more

The object of research is solvent sublation in the cobalt - sodium dodecyl sulphate system. The study of solvent sublation of wastewater from heavy metal ions is small and fragmented and unsystematic. Therefore, the study of the solvent sublation process,... see more

The ionic-interactions of acetic acid in H2O–PVOH and H2O–alco­hol–PVOH solvent systems were studied at different temperatures by the vis­cosity method. The viscosities of the poly(vinyl alcohol) (PVOH) were inc­reased with increasing concentration of PVO... see more

Plant extracts are used, among others, for the production of cosmetic preparations. However, their long storage may cause the degradation of valuable substances, reducing the antioxidant activity. The Plantago lanceolata L. and the Plantago major L. are a... see more

Special alcohols have been used as additives to study interfacial properties of cationic Gemini surfactant pentanediyl- 1, 5-bis (dimethyldodecylammonium bromide) (12-5-12). As these branched chain alcohols (in comparison with linear chain alcohols) are p... see more

Introduction-Ficus subincisa Buch-Ham.Ex Sm. is considered as an endemic medicinal plant. The current research based on antioxidant potential of four different green solvent extracts obtained by the successive solvent extraction method from the unexplored... see more

The lipase synthesis of wax esters using palm oil fractions (palm oil and palm kernel oil) and long chain alcohol as substrates was carried out. The present work focuses on the synthesis of wax esters using Lipozyme. Five parameters such as reaction time,... see more
