On the Electrolysis of Potassium Ethyl-Sulphone- 
Acetate. By Prof. Crum Brown and Dr Herbert 
W. Bolam. 
(Read February 15, 1897.) 
Ethyl-sulphone-acetic acid, C 2 H 5 S0 2 - CH 2 - CO OH, was pre- 
pared by Claesson’s method.* Fourteen grams of the potassium salt 
were dissolved in 20 c.c. of water, and the solution electrolysed for 
30 minutes under following conditions Volts, 12 ; amperes, 3*4 ; 
temperature, 30°-35° C. 
Carbonic anhydride and hydrogen were given off, and a white 
solid substance separated. This was collected on a filter and 
washed with cold water. The product, when dry, weighed 1‘7 
gram. It was purified by recrystallisation from chloroform. 
It forms needles, melting at 136°-137°. 
Analysis gave the following results : —

The results of analysis and the fusing point leave no doubt as to 
the identity of the substance, so that the electrolysis takes place in 
the normal manner,
