Barrier (Comptcs Rend., 114, 674) has described a compound 

 C,„H,sCl,, obtained by the prolong:ed action of hydrochloric acid on 

 hevo-linalool (b. p. (39 mni.) = i55°— 157° C. ; 0,,.,° = 1.0246). By 

 the action of acetic acid in presence of sodium acetate he obtained 

 from this compound: i) the acetate of an alcohol which he believed 

 to be identical with the alcohol ol>tained Ijy the direct action of the 

 same reagents on linalool ; 2) the ether-oxide of geraniol ; 3) a hydro- 

 carbon CjoHj,,, licarene, b. p. (760 mm.) = 176° — 178° C. 



MoRiN (Coinpfcs Rend., 92 999 and 94, 733), by the action of hy- 

 drochloric acid in aqueous solution exposed to sunlight during one 

 month, obtained a dihydrochlondc C,„U,>,0., (D,,;=: 1.069). optically 

 inactive, and incapable of distillation without decomposition. 



Bertram and Walbaum (/. /. prakt. Clicni., [2], 45, 597), by the 

 action of hydrochloric acid on linalool, obtained, after several recti- 

 fications in vacuo, a compound C^iiH^gCL (b. p. [11 mm.] 118° — 125° 

 C.) ; by the action of silver acetate on this compound they obtained, 

 after saponification, an oil having an odour of geraniol and linalool. 



Bariuer (Bull. Soc. chini., [3]. 9, 915) described a compound Cj,,- 

 Hj,Cl, (b. p. [17 mm.], I33°— 135° C . ; D„=i.0445), optically inact- 

 ive, derived from the dextrolinalool of oil of coriander. When 

 treated with acetic acid and sodium acetate, this compound yields a 

 hydrocarbon CioH^c, identical with inactive limonene. 



2) On geraniol: 



M. Jacobsen (Ann. Cheni., 157, 236) treated geranfol with gaseous 

 hydrogen chloride, and then with a concentrated aqueous solution 

 of the gas, in a sealed tube at 80°— 90° C. for one hour. He obtained 

 in this way a compound corresponding to the formula C,„Hi-Cl. 

 having a density of 1.02 at 20° C, and not distilling without de- 

 composition. The action on this body of alcoholic potash, ammonia 

 and water under pressure at 180° — 200° C. yielded the etheroxide 

 boiling at 187° — 190° C. under 760 mm. pressure. 



Barbier and Bouveault, by absorbing gaseous hydrogen chloride 

 in geraniol, allowing the temperature to rise, obtained a compound 

 C,„H,^Cl2. By the action of acetic acid and fused sodium acetate, 

 tiiis dichloro derivative yielded: 



i) A mixture of tetratoniie terpenes (b. p. 170° — 180° C.) 



2> Thie acetate of Icmonol which, on sa])onification, regenerates 

 pure lenwnol (geraniol). 



They conclude from this tlial their chloro bodv is a mixture of 

 cyclic and acyclic derivatives (Bull. Soc. chim., [3], 15, 594).
