Diethyl Mucoxychlorate, C^HC10^(CoH5)2. — Finely powdered ar- 

 gentic mucoxychlorate, which had been well dried over sulphuric 

 acid, was gradually thrown into an excess of ethyl iodide. The heat 

 evolved by the reaction was so great that the boiling point of the 

 ethyl iodide was soon reached, and the decomposition was afterward 

 completed by heating for a short time on the water-bath. The 

 product of the i-eaction was then extracted by dry chloroform, the 

 chloroform distilled off under diminished pressure, and the viscous 

 residue placed over sulphuric acid in vacuo. After long standing in 

 vacuo the product showed no signs of crystallization, but proved to 

 contain a percentage of chlorine which agreed tolerably well with that 

 required by the diethyl ether.

Monoethyl Mucoxychlorate, C^HoCIO^ . CgH.. — "When the viscous di- 

 ethyl ether just described was allowed to stand exposed to the air, or 

 when it was mixed with a small quantity of water, it rapidly acquired 

 an acid reaction, and gradually deposited well-formed crystals of the 

 monoethyl ether. The latter could also readily be prepared by extract- 

 ing with ordinary aqueous ether the product formed by the action of 

 ethyl iodide upon the silver salt, and allowing the ethereal solution to 

 evaporate spontaneously. The crystals which separated were thor- 

 oughly pressed and recrystallized from boiling benzol.
