In the chlorohydrination step, the reactants propylene and hypochlorous acid (chlorine and water) are converted into two propylene chlorohydrin isomers (90% l-chloro-2-propanol and 10% 2-chloro-l-propanol). Yields of up to 94% can be achieved in modern commercial plants. The main by-products formed in this reaction step are dichloropropane (3-10%), dichloropropanol (0.3-1.2%), and dichlorodiisopropyl ether (0.2-1.7%). In the second step (dehydrochlorination, also called epoxidation or saponification ) the aqueous propylene chlorohydrin solution is treated with slaked lime or caustic soda. Propylene oxide and calcium or sodium chloride are formed. In a commercial process 1.4-1.5 units of chlorine are consumed to produce one unit of propylene oxide. Typical by-products are monopropylene glycol, epichlorohydrin, glycerol monochlorohydrin, glycerol, propanal, and acetone. In dehydrochlorination, propylene oxide yields of up to 96% can be obtained. 

Procedure Approximately 20 mg or two drops of the sample are dissolved or suspended in 1.5 ml of one of the following solvents water, methanol, benzene, ether, 2,2 -dichlorodiisopropyl ether. One drop of one of the solutions described under 1 — 5 is added and then one drop of pyridine, which causes the formation of the characteristic color of the complex ferric salt (red, violet, blue). Two drops of acetic acid are then added, and if the color, which is different from that in the control experiment, persists, the presence of a chelate bond can be considered as proved (3, 4).
