Condensation Products of Menthane formed hy the 

 Action of Aluminum Chloride: Geo. B. Feank- 



FORTER AND A. L. NEWMAN. 



In view of the fact that aluminum chloride has 

 been found to act as a condensation agent on the 

 various hydrocarbons in the presence of oxygen 

 compounds as aldehydes and ketones, it was tried 

 on menthane, first in the presence of hydrocarbons, 

 and later it was tried on menthane alone. In the 

 former case benzene was used with menthane. A 

 substance was formed which did not contain oxy- 

 gen. Analysis indicated that it was a tetranuclear 

 compound containing two molecules of menthane 

 and two benzene radicals. A bromine derivative 

 was prepared. A condensation product was made 

 from menthane alone. Analysis indicated that it 

 was likewise a tetranuclear substance containing 

 four menthane radicles. Bromine compounds were 

 also prepared. Nothing as yet has been learned 

 of the molecular structure. 



The Polymers of Pinene: G. B. and 0. J. Prank- 



POETER. 



Pinene tends to form complex resinous sub- 

 stances when treated with any of the halogen ele- 

 ments, as chlorine, bromine or iodine in addition 

 to the formation of hydric salts. Not only do the 

 elements themselves react with pinene, but also 

 certain of their salts. Thus chlorine or aluminium 

 chloride added cautiously to pinene forms resinous 

 substances in addition to the hydrochloride and 

 tarry matter. The resinous matter thus formed 

 was found to be a complex substance. Two defi- 

 nite substances have been isolated and carefully 

 studied, while a third doubtless exists. Analysis 

 of the two which have been studied indicate the 

 formula (Ci„H„)2 and (C„Hie)4. 



The Electron Conception of Faience. A Labora- 

 tory Search for Electromers: Olivee Kamm. 

 The electron conception of valence as advocated 

 by Palk, Nelson and others predicts three isomers 

 in many cases where the theory of eis-trans isomer- 

 ism demands only one or two. An extensive search 

 was therefore made in order to isolate some of 

 these missing isomers. It has, however, been pos- 

 sible to explain all of the results obtained on the 



basis of the atomic linking theory without using 

 the electronic formulse for the double union. 

 The Rearrangement of (N) AlTcyl Anilines: C. G. 



DeEICK and J. W. HOWAED. 



The action of heat upon methyl aniline was 

 studied. No change was observed up to 500°. 

 Similar results were obtained with dimethyl ani- 

 line. 



The action of heat upon the methyl aniline 

 hydrochloride has been thoroughly studied. Under 

 temperature of 250° no shifting of the methyl 

 group from the side chain nitrogen atom to the 

 ring carbon atom was found. On the other hand, 

 the percentages of the primary, secondary and ter- 

 tiary amines was found to be constant within the 

 temperature limits 200°-250°, the times of heating 

 two to forty-eight hours, and the volume of the 

 bomb tubes. No quaternary compounds were de- 

 tected. The primary, secondary and Tertiary 

 amines were proven to be aniline, monomethyl ani- 

 line and dimethyl aniline, respectively. At 300° 

 the reaction is very different. The methyl radical 

 shifts from the nitrogen atom to the carbon atom 

 of the ring. 

 The Synthesis of l-Phen-3-Phenoxy-Propane by 



the Grignard Reaction: C. G. Deeick and L. O. 



POTTERP. 



For the preparation of the l-phen-3-phenoxy- 

 propane, phenyl magnesium bromide was prepared 

 in the usual manner. The solvent ether was evap- 

 orated off on a water bath. The residue was dis- 

 solved in one and one half moles of phenetol and 

 one mole of the l-bTomo-3-phenoxy-propane added. 

 The solution was now heated slowly to the boiling- 

 point under an air-condenser, when the last traces 

 of ether were slowly driven off. This heating re- 

 quires about an hour and is followed by three hours 

 refluxing. The yield of the l-phen-3-phenoxy-pro- 

 pane was 47 per cent., while if a few drops of di- 

 methyl aniline were added the yield was increased 

 to 61 per cent.
