Ethylene glycol CH2

It may be ptepd by nitration of ethylene glycol, (CH2)2(OH)2with a mixed nitric-sulfuric acid in the same apparatus that is used for prepn of NG. The glycol is prepd by synthesis from ethylene and ethylene chlorohydrin (See also Refs 12 13)... [Pg.504]

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]

Automotive antifreeze consists of ethylene glycol, CH2(OH)CH2(OH), a nonvolatile nonelectrolyte. Calculate the boiling point and freezing point of a 25.0 mass % solution of ethylene glycol in water. [Pg.535]

Ethylene glycol [CH2(OH)CH2(OH)] is the major component of antifreeze. Tt is a slightly viscous liquid, not very volatile at room temperature, with a boiling point of 198°C. Pentane (C5H12) which has about the same molecular weight, is a nonviscous liquid that is highly volatile at room temperature and whose boiling point is 36.1°C. Explain the differences in the physical properties of the two substances. [Pg.447]

Ethylene glycol [CH2(OH)CH2(OH)J is a common automobile antifreeze. It is water soluble and fairly nonvolatile (b.p. 197°C). Calculate (a) the freezing point and (b) the boiling point of a solution containing 685 g of ethylene glycol in 2075 g of water. [Pg.521]

You take advantage of freezing point lowering when you add antifreeze to your automobile radiator in winter. Ethylene glycol, HO(CH2)2OH, is the solute commonly used. It has a... [Pg.270]

A rather simple polymer can be made from ethylene glycol, HO—CH2—CH2—OH, and oxalic acid, HO—C—C—OH. [Pg.631]

Write the condensed structural formulas of the principal products of the reaction that takes place when (a) ethylene glycol, 1,2-ethanediol, is heated with stearic acid, CH,(CH2)i6COOH (b) ethanol is heated with oxalic acid, HOOCCOOH (c) 1-butanol is heated with propanoic acid. [Pg.901]

In the case of the cyclopentane oxirane 424, fluorination [KHFj, Me0(CH2)20H] proceeded to give preferably one fluoroalcohol, 426 (61%) over the isomeric one, 425 (7%), possibly by the influence of the benzyloxy-methyl group. Similarly (KHF2, ethylene glycol, 160°), another oxirane, 427, was converted into 428 (30%). 2-C-(Fluoromethyl)-/ T6>-inositol (429)... [Pg.165]

C12-0042. You are asked to prepare an aqueous solution of ethylene glycol (HOCH2 CH2 OH) with a mole fraction of 0.095. (a) If you use 545 g of water, what mass of ethylene glycol should you use (b) What is the molality of the resulting solution ... [Pg.880]

C12-0064. Ethylene glycol, an automobile coolant, has the chemical formula HOCH2 CH2 OH. Calculate the vapor pressure of water above a coolant solution containing 65.0 g of ethylene glycol dissolved in 0.500 L of water (density = 1.00 g/mL), at 100 °C, the boiling point of pure water. [Pg.882]

F5TeO(CH2)2OTeF5, cis-[0(CH2)20]TeF4, and related compounds are formed in reactions of TeF with ethylene glycol and other polyhydric alcohols (69). The alkoxotellurium(VI) fluorides isolated so far are distillable liquids with considerable stability against hydrolysis. Some of these compounds have been prepared more easily by reacting diazoalkanes with pentafluoroorthotelluric acid (174), as in Eq. (11) ... [Pg.218]
