Phenylethylene styrene

Styrene may be conveniently prepared in the laboratory by heating p-phenylethyl alcohol (Section IV,204) with sohd sodium or potassium hydroxide when an almost quantitative dehydration occurs  [Pg.1024]

In a 250 ml. distilling flask (1) place 122 g. (119 ml.) of p-phenylethyl alcohol and 40 g. of sodium hydroxide peUets (or 56 g. of potassium hydroxide). Heat is evolved. Warm gently until bubbles commence to form and the mixture separates into two sharply-defined layers. Distil slowly water, etc. passes over first accompamed by the gradual dis appearance of the upper phase. FinaUy the styrene passes over at 140 160° (mainly 150°) coUect this separately in a receiver containing about 0 1 g. of hydroquinone. Dry the distillate with a httle anhydrous calcium chloride or magnesium sulphate, and then distil under reduced pressure (2). C oUect the pure styrene at 42-43°/18 mm. The 3rield is 80 g. Add about 0-2 g. of hydroquinone (anti-oxidant) if it is desired to keep the phenylethylene. [Pg.1024]

Styrene is a colorless, oily, liquid aromatic hydrocarbon with a characteristic odor. It is sometimes called vinylbenzene or phenylethylene. Styrene is a monomer and must be inhibited during transportation and storage to prevent polymerization. It is a moderate fire risk, with a flammable range of 1.1 to 6.1%. The boiling point is 295°F, with a flash point of 88°F and an ignition temperature of 914°F. Small... [Pg.197]
