in methyl alcohol is allowed to stand for twenty-four hours, or when 

 mucochloric acid is dissolved in its own weight of methyl alcohol, 

 hydroxylamine hydrochlorate dissolved in a little water added in some- 

 what more than equivalent quantity, and the whole allowed to stand at 

 ordinary temperatures. If the solution is boiled even for a short time 

 the chief product is dichlormaleinimide. The ester may also be made 

 by the action of hydroxylamine hydrochlorate upon methyl mucochlo- 

 rate, provided the solution in methyl alcohol be allowed to stand for 

 several days.

The methyl ester of the mucochloroxime crystallizes in flattened 

 needles, the melting point of which varies with the mode of heating. 

 When introduced into a heated hath the substance melts promptly when 

 the temperature is held at 135°. At higher temperatures the melted 

 ester again solidifies, with the formation of dichlormaleinimide, which 

 in its turn melts at 173-174°, The ester is readily soluble in alcohol, 

 ether, or chloroform, and but sparingly soluble in benzol or carbonic 

 disulphide. It is also sparingly soluble in cold water, but dissolves 

 more readily in hot water, and, if the solution is quickly cooled, it 

 separates in long felted needles. On longer heating with water it is 

 converted into dichlormaleinimide. The ester may also be converted 

 into the imide by dissolving it in a solution of sodic carbonate, and 

 acidifying with hydrochloric acid, provided the solution is cold, and 

 moderately concentrated, and the acid is immediately added. 



Mucochloramide, C^ICIoOoNFL. — Mucochloramide is readily 

 formed when ammonia gas is passed into a solution of methyl muco- 

 chlorate in dry ether. The hard dark-colored mass which separates 

 is ground up in a mortar with small quantities of cold water. The 

 greater part of the coloring matter is thus removed, and the residue 

 may then be recrystallized from boiling water.

Mucochloramide is readily soluble in alcohol, sparingly soluble in 

 ether, and almost insoluble in chloroform. It dissolves readily in hot 

 water, and as the solution cools the greater part is deposited in the
