IOI 



1 ) Anethol from star anise oil or fennel oil is completely identical with that 

 from anise oil. 



2 ) Good anethol is always colourless. 



3 ) The congealing-point of a good preparation lies between 21 and 22°; when 

 the oil is imperfectly kept it falls considerably. Compare Report October 1904, 42. 



4 ) In order to dissolve 1 vol. anethol, 2 to 3 vol. 90 per cent, alcohol are required. 



Camphor (Camphora). A white, fatty, lustrous, tough, crystalline 

 mass, m. p. 175 to 177 , b. p. 204 to 208 ; burns with a highly lu- 

 minous flame; sparingly soluble in water, readily soluble in alcohol, 

 ether, chloroform, fatty and essential oils. Camphor should be com- 

 pletely soluble in spiritus cone, and, when slightly warmed, should 

 sublime without leaving a residue. 



Carvone (Carvonum). Colourless or faintly yellow; di5o 0,963 

 to 0,966; «d to the right 1 ); b. p. 229 to 230 ; soluble in any pro- 

 portion in spiritus cone, and at 20 in 20 parts spiritus tenuis \ test 

 with ferric chloride. Carvone is to be dispensed in lieu of caraway oil. 



*) The rotation lies between +57 anc * + 6o°. 



Cinnamic aldehyde (Cinnamalum). Yellowish; diso 1,054 to 

 1,056 x ); «d±o°; congeals when strongly cooled and melts again 

 at — 7,5°; b. p. about 252 under partial decomposition; soluble in 

 any proportion in spiritus cone; nitric acid test; silver mirror; ferric 

 chloride reaction; test for chlorides. Cinnamic aldehyde when heated 

 with a solution of bisulphite of sodium should dissolve completely. 

 Cinnamic aldehyde is to be dispensed in lieu of cassia oil. 



1 ) In our own preparations, we have observed up to 1,058. 



Eucalyptol [Eucalyptolum). Colourless or faintly yellow *) d^o 0,928 

 to 0,930; «d ± o°; b. p. 176 to 1 77 ; when strongly cooled down, 

 it congeals to a white, crystalline mass which melts at — i° 2 ); soluble 

 in any proportion in spiritus cone.) reaction with bromine. Eucalyptol 

 is to be dispensed in lieu of cajeput oil and eucalyptus oil. 



x ) A good article is always colourless. 



2 ) The m. p. lies between -f- 1 and -f- 1,5°. Compare Report October 1907, 49. 

 Congelation should, if necessary, be induced by rubbing the side of the vessel with 

 a glass rod. 



Eugenol (Eugenolum). Bright yellow; darkens in course of time; 

 d 15 o 1,070 to 1,074; a D ±o°; b. p. 251 to 2 53 °; soluble in any pro- 

 portion in spiritus cone, and in ether, also in 2 vol. spir. dil. With an 

 equal volume of caustic soda solution (25%NaOH) eugenol should 

 yield a solid crystalline mass. Ferric chloride reaction. 



Lavender Oil (Aetheroleum Lavandulae). Bright yellow or bright 

 greenish yellow; di 5 o 0,885 to 0,895; « D slightly to the left 1 ). Sap. no. 

 not below 90 2 ); soluble in any proportion of spiritus cone. 



*) The rotation lies between — 3 and — 9 . 



2 ) Corresponds to a minimum content of 31,5% Knalyl acetate.
