Action of Hydrochloric Acid on Morphia.

or chloroform solution with a very small quantity of strong hydrochloric 

 acid, the sides of the vessel become covered with crystals of the hydrochlo- 

 rate of the new base. These may be drained from the mother-liquor, 

 washed with a little cold water, in which the salt is sparingly soluble, and 

 recrystallized from hot water and dried on bibulous paper or over sulphuric 

 acid. No difference in the result appeared to be produced by continuing 

 the digestion at 150° for six or twelve hours. The new base may also be 

 formed by digesting morphia and excess of hydrochloric acid under 

 paraffin on the water-bath for some days. 



This hydrochlorate contains no water of crystallization. After drying in 

 the water-bath, it yielded the following results on combustion with chromate 

 of lead and oxygen : — 



(I.) 0*4300 gramme gave 1*0600 carbonic acid and 0*237 water. 



(II.) Sample (I.), recrystallized, and again dried in water-bath. 0*3270 

 gramme gave 0*8045 carbonic acid and 0*1830 water. 



(III.) 0*3830 gramme, burnt with soda-lime, gave 0*1240 metallic pla- 

 tinum . 



(IV.) 0*4720 gramme, burnt with soda-lime, and the ammonia estimated 

 volumetrically, gave 0*0234 nitrogen. 



(V.) 0*4680 gramme, precipitated by nitrate of silver and nitric acid, 

 gave 0*2170 chloride of silver. 



(VI.) 0*3410 gramme, burnt with lime, gave 0*1645 chloride of silver.

From a solution of the hydrochlorate in water, bicarbonate of sodium 

 precipitates a snow-white non-crystalline mass, which speedily turns green 

 on the surface by exposure to air, and is therefore difficult to obtain dry 

 in a state of purity. The following combustion of a portion washed with 

 water, and dried at 100° as rapidly as possible, shows that this precipitate 

 is the base itself. 



0*3310 gramme gave 0*9250 carbonic acid and 0*1830 water.
