Ethylene glycol antifreeze

Automobile Antifreeze. Ethylene glycol and diethylene glycol are used as automobile antifreeze, and are produced by the reactions of ethylene oxide with water, as follows ... [Pg.248]

The detection of water in some organic liquids is of considerable importance, e.g. both antifreeze (ethylene glycol) and aviation fuel (kerosene) should contain as little water as possible. Such materials can be monitored for water content by the use of non-dispersive infra-red techniques or turbidimeters (Section 6.8.1). [Pg.522]

Ethylene oxide, C2H4O, is used to make antifreeze (ethylene glycol, HOCH2CH2OH). It is produced industrially by the catalyzed air oxidation of ethylene ... [Pg.759]

Liquids dissolved in liquids similarly may form homogeneous solutions. Some liquids have limited solubility in water. Diethyl ether, CH3CH2OCH2CH3 (an organic liquid), is soluble to the extent of 4 g per 100 g of water at 25°C an excess of the diethyl ether will result in a separation of phases with the less dense organic liquid floating on the water. Some liquids mix in all proportions these liquids are completely miscible. The mixture of commercial antifreeze, ethylene glycol, HOCH2CH2OH, and water, used as a coolant in automobile radiators, is such a solution. [Pg.173]

This principle can be used in a number of practical ways. One application is the use of antifreeze in car radiators. Since water expands on freezing, the water in a car s cooling system can crack the engine block of a parked car when the outside temperature falls below 0°C. The addition of a common antifreeze, ethylene glycol, prevents this because the freezing point is depressed and the water-ethylene glycol mixture freezes at a much lower temperature. [Pg.193]

The most widely used antifreeze, ethylene glycol, is composed of 38.70% carbon, 9.74% hydrogen, and 51.56% oxygen. Its molar mass is 62.07 g/mol. Find its molecular formula. [Pg.216]

Alkenes are named using the root names of the alkanes, with the -ane ending changed to -ene. The simplest aUcene is ethene, CH2=CH2, which contains two carbons linked in a chain. Ethene, a gas at room temperature, is the most important organic compound used in the chemical industry. Almost half of the ethene used is converted into plastics. It is also used to make automobile antifreeze, ethylene glycol. Figure 18.6 shows another use of ethene. [Pg.630]

Antifreeze Ethylene glycol, used as an antifreeze in car radiators, has two hydroxyl groups, as shown below. What can you infer about the boiling point, freezing point, and solubility in water of this compound from its structure ... [Pg.647]

Solutions freeze at lower temperatures than the solvents used to prepare them. When antifreeze (ethylene glycol, C2H602) is added to the water in the radiator of a car, the water-glycol solution will remain liquid at temperatures far below the normal freezing point of water itself. Salt and calcium chloride spread on snow-covered roads in the winter dissolve in the snow, forming solutions that are liquid at temperatures at which pure water is solid. The depression of the freezing point is symbolized ATFP and is used as a positive number. [Pg.374]

How many liters of the antifreeze ethylene glycol [CH2(0H)CH2(0H)] would you add to a car radiator containing 6.50 L of water if the coldest winter temperature in your area is — 20°C Calculate the boiling point of this water-ethylene glycol mixture. (The density of ethylene glycol is 1.11 g/mL.)... [Pg.500]

For these reasons, societal needs are increasingly being formulated that call for new processes to avoid or sharply reduce the handling of hazardous chemicals. As an example, consider the manufacture of ethylene glycol, the principal ingredient of antifreeze. Ethylene glycol is produced commonly by two reactions in series ... [Pg.164]

In 1990, Fleischmann et al. used NIR Fourier transform SERS (NIR FT-SERS) [71] to study the Cu corrosion inhibitors, benzotriazole and tolyltriazole. Diagnostic bands were identified for each compound, whereby benzotriazole and tolyltriazole were coadsorbed and found to displace each other, depending on their relative concentrations. The NIR FT-SERS investigations were extended to an antifreeze (ethylene glycol) mixture [24], in which both benzotriazole and tolyltriazole were identified by SERS as being adsorbed... [Pg.148]

Water dissolves many covalent (molecular) compounds also. Table sugar (sucrose, C12H22O11), beverage (grain) alcohol (ethanol, CH3CH2OH), and automobile antifreeze (ethylene glycol, HOCH2CH2OH) are some familiar examples. All contain their own polar bonds, which interact with the bonds of water. However, most soluble covalent substances do not separate into ions, but remain intact molecules. For example,... [Pg.120]

The freezing point of water is 0.00°C at 1 atmosphere. Kj for water is 1.86°C/m. A molecular substance that dissolves in water is antifreeze (ethylene glycol). If 11.35 grams of antifreeze, CH2OHCH2OH (62.10 g/mol), is dissolved in 272.3 grams of water, what are the molality and the boiling point of the solution ... [Pg.499]
