A modified Sherwood-Gilliland equation for mass transfer in the gas phase is applied to gas absorption in scrubbers. The equation can be written in the following dimensionless form: where the dimensionless groups have the following significance The e

Measurements of mass transfer coefficients in film reactors are reported. Turbulence due to entrance effects is shown to explain why mass transfer coefficients in the gas film may be proportional to the 0.8th power of mass velocity even, within the r

The oxidation of cyclohexanol with nitric acid to adipic acid proceeds via two stable intermediates known from the literature1 viz. 6-hydroxyimino-6-nitro hexanoic acid and the hemihydrate of 1,2-cyclohexanedione, two substances forming beside each o

The solubilities of some aromatic hydrocarbons in pyridine have been measured. The entropies of fusion derived from these measurements agree qualitatively with the values which can be calculated, if it is assumed that their molecules obtain one rotat

The rheology of concentrated polymer solutions shows a remarkable correspondence with that of polymer melts, but is more complicated due to a new parameter: the concentration of the polymer. The literature shows evidence that the viscosity of concent
