The hydro-chloride salt of isonicotinamide, C6H7N2O(+)·Cl(-), has been synthesized from a dilute solution of hydro-chloric acid in aceto-nitrile. The compound displays monoclinic symmetry (space group C2/c) at 150 K, similar to the related hydro-chloride salt of nicotinamide. The asymmetric unit contains one protonated isonicotinamide mol-ecule and a chloride anion. An array of hydrogen-bonding...

this study examines the effects of change in the concentrations of monovalent and divalent ions in the polymer-contained surfactant solution on the macroscopic behavior of viscous-modified surfactant waterflooding in heavy oil reservoirs. salts that are used in this set of floods were sodium chloride, magnesium chloride, and calcium chloride. the results indicate that four different ranges of s...

a study was conducted to standardize production and postharvest handling of lily (lilium longifolium l. cv. mero star). in production trial, three plant densities viz.10, 20 and 30 cm between plants in 60 cm spaced rows and two planting depths viz.7.5 and 15 cm were compared. increased plant growth, yield and quality was recorded when plants were grown at a close spacing of 10 cm with 15 cm pla...
