The coolant temperature is -35°C when the refrigerant is composed of 50% propylene glycol and 50% water. The main ingredient in antifreeze is propylene glycol, which accounts for about 45% of the original coolant.

A variety of natural alcohols are effective antifreeze. Since the 1950s, practically all nations have used ethylene methanol as antifreeze. Ethylene ethanol is a clear, white, somewhat special, and soluble sticky liquid that can be dissolved in any proportion. The propylene glycol attention is different at the same time. The freezing level is also unique. The large proportion of propylene glycol is no horizontally related to the melting point of ethanol glycol-water coolant. When the focus exceeds 70%, the melting point of its watery solution increases, but the temperature does not simply rise with the increase in intensity. Instead, the melting point rises. It should be chosen fairly from the practical point of view when preparing in order to meet the requirements of antifreeze and business. The percentage of ethanol mass fraction in the north of China is typically used, while the cold northern uses a percentage of methanol mass portion of about 50%. 【キーワード】 Ethylene、Glycol
