with tin and hydrochloric acid, asarylamine (i, 2, 5-trimethoxy-4-amido- 

 benzene), (CH 3 0) 3 • C 6 H 2 NH 2 , m. p. 95 , is obtained. The benzoyl 

 compound produced for identification melts at 13 8°; from the asarylamine 

 is formed with asaryl aldehyde a Schiff's base, trimethoxybenzylidene 

 trimethoxyamidobenzene (asarylidene-asarylamine) of the m. p. 142,5°. 

 When asaronic acid is boiled with sodium nitrite, not only the 

 carboxyl-group is split off, but also a methoxyl-group , and they are 

 replaced by a hydroxyl- and nitroso -group, or a quinone- and oxime- 

 group respectively. The process yields extremely stable bodies, which 

 condense with amines and amidophenols to quinone-imide dyes. 



Eugenol. On the 5-azoeugenols and the constitution of the 

 so-called o-oxyazo compounds, a communication has been published 

 by G. Oddo and E. Puxeddu 1 ). If diazonium salts are allowed to 

 act on solutions of eugenol in alkalis, there are formed azoeugenols 

 which must be regarded as pseudo acids, as they cannot be accepted 

 as azophenols owing to their stronger acid properties. The alkyl ethers 

 of azoeugenol are true oxyazo bodies; the acetyl derivatives on the 

 other hand contain the acetyl linked to the nitrogen. 



E. Puxeddu 2 ) has also conjointly with M. Cornelia, produced 

 nitroisoeugenol. This body, of the formula C 10 H 11 O 4 N, decomposes 

 without melting at 1 50°. It can be acetylised, and then yields a body 

 C 12 H 13 5 N which on being heated above 200° decomposes. 



Thymol. Whilst it was formerly believed that a combination of 

 phenols and trichloracetic acid was impossible, a recent notice 3 ) states 

 that Thymylum trichloraceticum can be produced in a comparatively 

 simple manner. When experimenting in accordance with the directions, 

 O. Anselmino 4 ), however, obtained regularly a product free from 

 chlorine, which was identified as unchanged thymol. Only by thymol 

 sodium with trichloracetylchloride in petroleum ether, a body was ob- 

 tained which left no doubt as to its identity with the thymol ester 

 of trichloracetic acid. The ester boiled at 12 mm. pressure at no to 

 in°, but could only be produced in liquid form. It was readily 

 saponifiable, and when digested with aniline yielded thymol and the 

 trichloracetanilide melting at 95°.
