Densities of the systems of tert-butanol (TB) + n-butylamine (NBA), + di-n-butylamine (DBA) and + tri-n-butylamine (TBA) were determined between 303.15 and 323.15 K at different compositions in the range 0 ≤ x 2 ≤ 1, where x 2 is the mole fraction of butylamines BA, NBA, ...
thefreezingof t-butanol and that of a t-butanol and aspirin solution; then finding the molality of the solution‚ and moles of aspirin. In the results of the experiment‚ themolarmasswas found to be 192.2 g/mol‚ which differed from the established value of 180.2 g/mol by 6.7% ...
Mixtures of low molar mass polyester polyols having a weight-average molar mass Mw of not more than 2000 g/mol, with hydroxyl numbers of from 80 to 300 mg/g and acid numbers of from 5 to 35
Let the mass of each gas present in the mixture be mi. Then the mass balance gives the total mass of the mixture mm as (12.1)mm=m1+m2+⋯+mN=∑i=1Nmi The corresponding number of moles ni of gas i with molecular mass Mi can be determined from Eq. (1.9) as (1.12)ni=mi/Mi ...
