1. On a new mode of forming the organic sulphacids—S 
cetic, isethionic, methionic, and other organic sulphacids give of at 
phurous acid when heated with potash, and may therefore ber 
garded as derived from neutral sulphites by the substitution 
half the metal by an alcoholic or acid radical, 
succeeded in effecting this substitution directly 1 in & nonbetd 
eases. Thus iodid of methyl heated to 150° C. with a solutiont 
sulphite of soditi yields methyl-sulphite of sodium:

Peichiochyarin and sulphite of potassium yield chlorid of polt

The chlorinated acids behave in a similar manner; thus pe 
chloracetic acid by boiling with an alkaline sulphite, yields at 
kaline chlorid and sulphaceta
