Ag/AgBr electrodes are not suitable in diethylamine solvent in charge plate collection experiments

Tue, 01 Nov 1994 00:00:00 GMT

Title: Ag/AgBr electrodes are not suitable in diethylamine solvent in charge plate collection experiments Authors: Zaman, M R Abstract: Ag/Br is found soluble in diethylamine solvent. This makes Ag/AgBr electrodes unsuitable in recoil bromine studies through charge plate collection experiments. Page(s): 376

Hydrocarbon composition of straight run middle distillate correlated with diesel index

Tue, 01 Nov 1994 00:00:00 GMT

Title: Hydrocarbon composition of straight run middle distillate correlated with diesel index Authors: Sharma, R L; Dimri, J K; Bhatt, K P Abstract: A Mathematical equation has been developed to predict the diesel index of middle distillate from %C_p, %C_N and %C_A data derived from n-d-m analysis. Regression coefficient of 0.96 with a standard deviation of residuals of 0.42 shows that the suggested equation is statistically satisfactory and is useful in assessing diesel index of distillate fuels from hydrocarbon composition.

Title: Synthesis of novel esters of 4-(2'-phenylisopropyl)phenol used as column packings for gas liquid chromatography Authors: Tambe, A S; Biswas, S S; Ayyangar, N R Abstract: Five esters have been prepared from 4-(2'-phenylisopropyl) phenol which is one of the by-products in the manufacture of phenol with a view to characterize their resolving abilities when used as stationary phases in gas liquid chromatography. The spectral data and physical characteristics of these esters have been described. Page(s): 371-372

Solvent effects on the dissociation of 3-methylbenzoic acid in aqueous binary mixtures of 2-methoxyethanol at 298.15 K

Title: Solvent effects on the dissociation of 3-methylbenzoic acid in aqueous binary mixtures of 2-methoxyethanol at 298.15 K Authors: Maitra, Basanti; Das, Bijan Abstract: The solubilities of 3-methylbenzoic acid in 2-methoxyethanol (ME)-water mixtures (0 to 80 mass % of ME) have been measured at 298.15 K. The thermodynamic dissociation constants (K_T) have been determined from the solubility values in conjunction with pH measurements. Page(s): 369-370
