Hlasiwetz on two New Bodies obtained from Phloretine. 203 



which it is separated by washing with water. It is an amor- 

 phous powder, and does not readily form salts ; is little soluble 

 m alcohol and water, as also in chloroform and Eether. It is a 

 product of decomposition of paranitraniline, as Arppe found by 

 direct experiment. A pure specimen prepared in the above 

 manner from paranitraniline gave analytical results which led 

 to the formula C^^ hs n^ S^ 0*. Arppe has named it nithialine. 

 With none of the bases formed by Zinin's process does this 

 substance, or any analogous one, seem to be produced, except 

 with paranitraniline, as direct experiment showed. 



Hlasiwetz gives a preliminary account of two new bodies 

 which he has obtained from phloretine. This body is boiled 

 with strong potash, the solution evaporated, and the excess of 

 potash removed by carbonic acid. If the liquid be then further 

 evaporated and treated with alcohol, the potash salt of a new acid 

 IS obtained, which he has named phloretic acid. It is easily puri- 

 fied, possessing a great tendency to crystallize. It expels CO^ 

 from Its salts, uniting with the base to form easily crystallizable 

 salts. Of these the baryta and zinc salts are the most beautiful. 

 It has the same deportment with reagents as lichenic acid. Its 

 formula is C^^ H'o 0^, HO. It is monobasic ; the formula of its 

 salts is C'SHJOOS, MO. 



The salt residue from which the phloretate of potash had been 

 dissolved out, and the carbonate of potash, contain an interesting 

 neutral body. This is obtained by treating the solution of the 

 residue in water with dilute sulphuric acid, evaporating again 

 and treating the mass with alcohol. The alcoholic solution is 

 agam evaporated, and the residue crystallized out of water. Its 

 most remarkable property is its sweetness, from which it has 

 been named phloroglucine. It has the greatest resemblance to 

 orcine, and gives, like it, a bromine substitution compound. 



The formula of the body crystallized from water is C'^H'^O'" 

 for that crystallized from aether, C'^ H*^ 0^. The bromine com- 

 pound contains 3 equivs. hydrogen, replaced by bromine, and 

 is, in its properties, very similar to bromorceid. 



As by the decomposition of phloretine by alkalies no other 

 body is formed, it may be expressed thus : — 



C30Hi5 0'o + KOHO = C'8H»oo^KO + C'2H6 06. 

 These bodies stand evidently in a very near relation to the con- 

 stituents of lichens. 



The same author makes a communication, that direct experi- 

 ments have convinced him that quercitrine and rutinic acid are 

 identical, and have the formula C^^H'^O^'. The discrepancies 

 exhibited by some of the analyses of the latter body with the
