Reactions of Hydroxyl Radicals with Several Hydrofluorocarbons: The Temperature Dependencies of the Rate Constants for CHF2CF2CH2F (HFC-245ca), CF3CHFCHF2 (HFC-236ea), CF3CHFCF3 (HFC-227ea), and CF3CH2CH2CF3 (HFC-356ffa)

The Journal of Physical Chemistry, 1994
Rate constants were determined for the gas-phase reactions of the hydroxyl radical with four hydrofluorocarbon compounds, CF 3 CHFCF 3 (HFC-227ea), CF 3 CHFCHF 2 (HFC-236ea), CHF 2 CF 2 CH 2 F (HFC-245ca), and CF 3 CH 2 CH 2 CF 3 (HFC-356ffa), using the flash photolysis resonance fluorescence technique over the temperature range 260-365 K.

Measurements of liquid densities of the binary HFC-32 + HFC-134a system

Fluid Phase Equilibria, 1994
Abstract Thirty measurements of saturated-liquid density and bubble-point pressure, and twenty-two P ϱ Tx data in the liquid phase of binary HFC-32 + HFC-134a systems have been obtained over a temperature range of 280–340 K. using a magnetic densimeter coupled with metallic bellows.

HFCS: A Sweetener Revolution

1983
The development of high fructose corn syrup (HFCS) over the last 10 years has radically altered the conventional process of producing and distributing sweeteners, caused the reformulation of many food and beverage products, and reshaped the sugar industry.
