The oxidation of propylene glycol l>y means of 

 alkaline potassium permanganate: W. L. Evans, 

 J. E. Day and "W. E. Stemen. 



The oxidation of isopropyl alcohol and acetone 

 by means of alkaline potassium permanganate : W. 

 L. Evans and Lilt Bell Sefton. 



The influence of alkali on the formation of vinyl 

 alcohol from acetaldehyde : W. L. Evans and C. D. 



LOOKEB. 



The solubility of dichloro-diethyl-sulfide in pe- 

 trolewm hydrocarbons and its purification by ex- 

 traction with these solvents: Thomas G. Thomp- 

 son and Henry O'Deen. 



Searrangement of unsaturated acids: Oliver 

 Kamm and M. E. Dreyfus. 



The reaction velocity of dealkylation of tertiary 

 amines mith acyl halides: Oliver Kamm and W. 

 r. Day. 



The alcoholysis of esters with amino alcohols: 

 Bupus M. Kamm. 



Secretions of the arsines. Condensation of pri- 

 mary airsines with aldehydes: Eoger Adams and 

 Charles Shattuck Palmer. Aromatic aldehydes 

 and aliphatic aldehydes readily condense with 

 phenyl arsine, when a few drops of hydrochloric 

 acid are present, to give products consisting of two 

 molecules of aldehyde and one of phenyl arsine. 

 These substances are stable to water, dilute alkali 

 and acid, and are probalbly represented by the 

 structural formula given in the following equation : 



2 ECHO + EAsH,-^EAs(CHOHE),. 



On the non-identity of a-eleosteria acid from 

 tung oil with ordinOiry linolic acid: Ben. H. Ni- 

 COLET. a-eleostearlc acid is readily prepared from 

 tung oil (China wood oil). On bromination in 

 glacial acetic acid it is known to form a tetra- 

 bromide m. 115° which Lenkowitsch ("Oils, Fats 

 and Waxes," Vol. I.) suggests is identical with 

 linolic acid tetrabromide, m. 114°. A mixed melt- 

 ing poinjt showed a lowering of 15°, go that the 

 two are obviously different. Bromination of the 

 eleostearic acid in ligroin leads to the formation of 

 a dibromide, with altogether different properties. 



A new type of nitrogen-sulfur compounds; the 

 action of chloramine-T on organic sulfides: Ben. 

 H. NicoLET and Imogene D. "Willard. On boil- 

 ing together in alcoholic solutions diethylsulfide 

 (OaH,)jS and chloramine-T,

eince it is hydrolyzed to give p-toluenesulfonamids, 

 and a product which on reduction gives diethyl- 

 sulfide and which is presumed to be diethylsul- 

 foxide. The reaction is believed to be rather 

 general. Compounds containing N and S linked by 

 a double bond, have been practically unknown. 



Seport on the progress of the manufacture of re- 

 search organic chemicals: Hans T. Clarke. The 

 present report covers the work of this department 

 of the Eastman Kodak Company during its second 

 year of activity. As was to be anticipated, the 

 progress made has been very much greater than 

 during the fijst year as regards both the number 

 of chemicals available and quantities distributed. 

 At the present time nearly 800 different chemicals 

 are available, almost all of these being organic, the 

 balance consisting of certain inorganic chemicals 

 employed principally in organic work. Of these 

 800 substances, about 600 have been prepared in 

 our laboratory, some by purification of materials 

 technioally available, but the majority by synthesis. 

 Over 600 different preparations have been under- 

 taken, almost all of which have ultimately been 

 successful. In a certain number of instances 

 more than one product is obtained, either as a by- 

 product or as an intermediate stage. A good deal 

 of time is naturally now 'being spent upon the re- 

 newal of depleted stocks by methods which have 

 already been developed in the laboratory, but the 

 preparation of new compounds is still regarded as 

 being a most important part of our work. Be- 

 tween 10 and 20 new chemicals are added to the 

 list every month, and these are announced in the 

 advertising columns of certain of the scientific 

 periodicals. A file is kept of the names of mate- 

 rials for which inquiry is made, and this is con- 

 stantly before us in the selection of new prepara- 

 tions. As soon as any chemical for which such in- 

 quiry has been made is available, the fact is made 

 known to the party from whom the inquiry was re- 

 ceived. It is in many cases difficult to decide 

 whether or not a specific chemical should or should
