596 THE GRIGNARD SYNTHESIS : THE ACTION OF 



The yield was nearly ten grams, about twenty-five per cent., 

 of the theoretical yield. As has been meintion^d above, the 

 action between the ketone and halide is a gradual one; the 

 small yield and the large quantity of uncombined camphor are 

 probal)]y due to the mixture not having been allowed to stand 

 sufficiently long. 



This new alcohol is a pale yellow oil, with a balsam-like- 

 taste. It is miscible with alcohol, ether and chloroform. Its 

 specific gravity is 0.977, 



The boiling point of this oil is 143°-145°C. at 14 mm.. 

 pressure and 258°-260° at 760mm. 



Molecular Weight. 



Its molecular weight was determined by the Victor Meyer- 

 method.

Analysis. 



Two analyses of the oil were made, but owing to an acci- 

 dent one was a failure, and there was not enough oil to make- 

 a third.

Specific Rolation. 



The specific rotation was determined, but owing to the thick- 

 ness nnd colour of the liquid only a small quantity could be 

 used. Consequently the deflection of the plane of polarisation 

 was very small, le?,s than one degree, and the percentage error 

 probably as great as 5^.
