D e w and Bubble Isotherm Calculational Method For Binary System Phase and Volumetric Behavior

S. IC. Bhattaciiar);kz and A . K . Sen, Indian Institute of Technology,

Kansas

A systematic study of synthesis of acrylic acid and of ethyl acrylate, using various salts of iron, cobalt, and nickel as catalysts. Reduced iron, cobalt, and nickel and their carbonyls were practically inactive; their halides and naphthenates exhibited excellent catalytic activity. Under most favorable conditions, conversions of ethyl acrylate and acrylic acid were 61.3% and 8,6yoon the basis of input acetylene. .\Is. 63-749

Thermostated bath operates with either liquid or gas heat transfer media, using liquid nitrogen or helium refrigerant. Measurements of saturated volumetric behavior of nitrogen indicate apparatus can be used to determine liquid densities within a few tenths of a per cent, and saturated vapor phase compressibility factors with an accuracy of about 2%.

Totally immersed porous hydrazine fuel anodes were evaluated for electrochemical performance and current efficiency for use in fuel cell operation. Performance shows promise for special aerospace and ground applications. Close to 9 5 % current efficiencies are possible with 0.2.M N2H4 and 6.9.U KOH electrolyte. Water removal and prevention of C 0 2 contamination are problems.

Characteristics OF Single and Multiple Hole Orific Plates for Gas-Liquid Reactions

Simultaneous mass and heat transfer, associated with evaporation of water from surfaces of celite spheres, studied at high Reynolds numbers. Unexpected transitional behavior presents novel feature not encountered previously in similar studies. Information should prove of value for study of catalytic reactions associated with fast surface action rates, and for through-circulation drying requiring high rates of air f l o ~ v .

Effects of design variables on contactjng efficiency studied, using the air-sodium sulfite system, and flow characteristics examined with high-speed motion pictures. Results are compared with data on agitated-tank reactors.

A N e w Phosphorylation Reaction of Oleflns. Derivatives of Alpha-Olefins

$2.00

Relatively new procedure for synthesizing organic phosphorus compounds from olefins 1,2,3,4,6 has been extended to some commercially available alpha-olefins. Method is based on reaction of an olefin with phosphorus trichloride and aluminum chloride in cold methylene chloride as the solvent. Resultant products are mixtures of saturated phosphinic acid chlorides and acids.

Chemical Engineering Viewpoint

Samuel W . Bodman, Charles A . Gray, Robert C. Reid, and George W. Roberts, Massachusetts Institute of Technology

Rapid prediction of vapor pressures in low and high pressure regions, using only the normal boiling point a n d critical point as input data. Predicted vapor pressures slightly better than those from Riedel and Frost-Kalkwarf equations. Calculations considerably simpler.

A general expression relating rate of entropy production to rates of heat, mass and charge transfer, and rate of chemical reaction is derived. Relation between entropy production and loss of useful work is discussed. An example of use of minimization of entropy production in selecting proper layout of a multicomponent distillation system is given.
