phosphorus, the chloride, bromide and iodide of the acryl series are 

 reproduced with the greatest facility. 



Acrylic alcohol dissolves in concentrated sulphuric acid, without 

 separation of carbon ; the liquid, mixed with water and neutralized 

 with carbonate of barium, furnishes a crystalline salt, which contains, 

 C 6 H 6 BaS 2 8 =BaS0 4 , (C 6 H 5 ) SO 4 . 



This is the sulphovinate of the series. 



On treating the mixture of acrylic alcohol with concentrated 

 sulphuric acid, a most violent reaction takes place ; the alcohol is 

 entirely carbonized with evolution of sulphurous acid. 



Anhydrous phosphoric acid affects the alcohol with less energy. 

 The mass darkens with evolution of a transparent colourless gas, 

 burning with a luminous flame. The analysis of this gas remains 

 to be made. 



Acrylic alcohol is rapidly attacked by oxidizing agents. A mix- 

 ture of sulphuric acid and bichromate of potassium acts with tre- 

 mendous violence ; the products of the reaction being acroleine and 

 acrylic acid, or its products of decomposition. The same transform- 

 ation is effected by spongy platinum. 



When treated with potassa and bisulphide of carbon, the new alco- 

 hol solidifies at once into a mass of splendid yellow needles, which 

 correspond to xanthate of potassium. 



By the aid of the alcohol itself, its sulphovinic acid, or its iodide, 

 all the terms of the acryl series may be produced with the greatest 

 facility. We will specify the following compounds, the study of 

 which we have more or less completed. 



Acryl- oxamethane, or oxamate of acryl, is readily formed by 

 adding alcoholic ammonia in small quantities to oxalate of acryl, 

 until a permanent precipitate is produced. The filtered solution de- 

 posits on evaporation the oxamate in magnificent crystals. 



Carbonate of acryl is an aromatic oily liquid, lighter than water. 

 It is formed like the other carbonic ethers, by the action of sodium 

 upon the oxalate. An alcoholic solution of this substance, when 

 treated with baryta, furnished carbonate of barium and acrylic 

 alcohol. 



Benzoate of acryl is readily produced by the action of chloride of 

 benzoyl upon acrylic alcohol. It is a liquid heavier than water,
