Freezing Points of the System Ethylene Glycol–Methanol–Water

Abstract

THATan antifreeze of superior qualities might be developed by mixing methanol and ethylene glycol, two of the most widely used antifreeze materials, seems apparent. The use of methanol would lower the cost and the glycol would lower the volatility of the methanol. Both methanol and glycol produce only small increases in viscosity (S) when added to water and hence permit nearly normal radiator circulation and heat transfer.

Effect of Inhibitor Methanol on the Microscopic Structure of Aqueous Solution

“…Some equilibrium measurements in methanol-water mixtures under atmospheric pressure are available. 12,13 However, there are few measurements under high pressure. Therefore, we measured solid-liquid equilibrium properties under atmospheric and higher pressures for this system and examined the effect of pressure.…”

Analysis of System Methanol-Ethylene Glycol-Water

“…The glycol thus obtained had a refractive index of 1.4314 ra2D°and an absolute density of 1.1105 d25. Values of refractive index found in the literature are 1.4311 n2D°(7), 1.4318 ra2D°(6), 1.4314 ray (3), 1.43178 ra2D°(4), and 1.4304 n2D°(1), and values of density are 1.1110 d|3 (£), 1.1097 d25 (7), 1.1103 d|5 (1), and an absolute density of 1.1101 d25 (8).…”

Hybrid mixture theory‐based modeling of transport of fluids, species, and heat in food biopolymers subjected to freeze–thaw cycles

“…When ethylene glycol-based liquid is used for cooling, the product temperature drops quickly over a small period of time (Peyghambarzadeh et al, 2011), which makes it easier to utilize this freezing method to test a complex freezing model such as the one presented in our manuscript. Ethylene glycol is an antifreeze that has a low freezing point (60% ethylene glycol aqueous solution's freezing point is about −46 • C; Conrad et al 1940) and provides a significantly higher surface heat transfer coefficient than air cooling (Table 3). Next, the effects of fluctuating freezing temperature at different amplitudes and frequencies, and intermittent freezing conditions caused by opening and closing of freezer doors are discussed.…”
