An efficient and expedient protocol for the synthesis of benzyl phosphonates using KI/K2CO3 as a catalytic system and PEG-400 as benign solvent has been developed. The reaction proceeds smoothly at room temperature achieving excellent selectivity and yield of the corresponding products. The combination of PEG-400, KI, and K2CO3 in this reaction avoids the need of volatile/toxic organic solvents...

The aim of this study was to evaluate the pH and antimicrobial activity of micro or nanoparticulate zinc oxide (ZnO) pastes with or without calcium hydroxide (CH). The following medications were evaluated: microparticulate ZnO + polyethylene glycol (PEG) 400; nanoparticulate ZnO + PEG 400; PEG 400; CH + microparticulate ZnO + PEG 400 and CH + nanoparticulate ZnO + PEG 400. The pH was assessed b...

Introduction: The Papuan people have utilized the native herb Laportea decumana (Roxb.) Wedd for centuries to treat aches and pains L. is used by attaching leaves to the body area with illness. Methods: This study aimed test optimal composition of PEG 400 and 6000 in L.decumana  simplicia ointment formula produce a good ...

Relatamos algumas moléculas híbridas baseadas na N-(quinolina-3-ilmetileno)benzoidrazida, cuja síntese foi realizada usando-se 2-cloroquinolina-3-carbaldeído e uma variedade de hidrazidas substituídas, em PEG 400. O solvente PEG 400 foi recuperado e reutilizado diversas vezes na presente reação, mostrando-se eficiente em termos de rendimento dos produtos. Alguns dos compostos sintetizados mostr...

Plasticizer effect on oxygen permeability (OP) of beta-lactoglobulin (beta-Lg) films was studied. Propylene glycol (PG), glycerol (Gly), sorbitol (Sor), sucrose (Suc), and polyethylene glycol at MW 200 and 400 (PEG 200 and PEG 400, respectively) were studied due to their differences in composition, shape, and size. Suc-plasticized beta-Lg films gave the best oxygen barrier (OP < 0.05 cm3 x micr...

BACKGROUND Increased intestinal permeability is an important measure of disease activity and prognosis. Currently, many permeability tests are available and no consensus has been reached as to which test is most suitable. The aim of this study was to compare urinary probe excretion and accuracy of a polyethylene glycol (PEG) assay and dual sugar assay in a double-blinded crossover study to eval...

Today concrete is most widely used construction material due to its good compressive strength and durability. Depending upon the nature of work the cement, fine aggregate, coarse aggregate and water are mixed in specific proportions to produce plain concrete. Plain concrete needs congenial atmosphere by providing moisture for a minimum period of 28 days for good hydration and to attain desired ...
