    摘要: THE LONG TERM THERMAL STABILITY OF HALOGENEATED POLYPHENYL HEAT TRANSFER FLUIDS IS IMPROVED BY ADDING A PHOSPHOROUS COMPOUND TO THE FLUID AND PROVIDING AN INERT GAS PURGE TO SWEEP GASEOUS DECOMPOSITION PRODUCTS FROM THE HEAT TRANSFER SYSTEM. FLUIDS MAINTAINED IN THIS MANNER ARE LESS CORROSIVE, FORM LESS SOLID DECOMPOSITION PRODUCTS, AND UNDERGO A SMALLER VISCOSITY INCREASE THAN UNTREATED FLUIDS WHEN EXPOSED TO HIGH TEMPERATURE APPLICATIONS FOR EXTENDED PERIODS.

    摘要: Corrosion resistant antifreeze compositions consisting essentially of at least one antifreeze fluid having from 1 to 4 carbons inclusive and from 1 to 3 hydroxy groups inclusive and a minor but effective amount sufficient to inhibit corrosion of an alkali metal dialkyl phosphate. The alkali metal dialkyl phosphate can be represented by the formula:

    摘要: Dichlorodifluoromethane (CC12F2) and 1,1,1,2-tetrafluoroethane (CF3CH2F), in certain proportions, form an azeotrope and essentially azeotropic mixtures, which are constant boiling, or essentially constant boiling, and which mixtures possess refrigeration capacities higher than either of the CC12F2 and CF3CH2F components alone. These mixtures are especially adapted for use in systems having high-condensing temperatures such as automobile air conditioning systems.

    摘要: IMPROVED HEAT TRANSFER ADDITIVES FOR LITHIUM BROMIDE ABSORBENT SOLUTIONS ARE SELECTED FROM A CLASS OF TERTIARY ALCOHOLS. THE TERTIARY ALCOHOLS HAVE GREATER OXIDATIVE STABILITY AND, THEREFORE, DO NOT REACT AS RAPIDLY WITH THE CHROMATE CORROSION INHIBITORS WHICH ARE COMMONLY USED IN THE ABSORBENT SOLUTIONS. IN ALL CASES, THE HEAT TRANSFER IMPROVEMENT IS AT LEAST AS GOOD AS KNOWN, LESS STABLE, PREMARY (AND SECONDARY) ALCOHOLS.
