Thiocyanogen solution standardization

The thiocyanogen solution is standardized by treating with an excess of potassium iodide and titrating the liberated iodine with standard sodium thiosulfate. The burette containing the halogenoid solution is protected against moisture by a tube containing calcium chloride or phosphorus pentoxide.

The reaction of thiocyanogen with unsaturated fatty acids has been introduced as a method of analysis. Excess of a standardized thiocyanogen solution is used, and the amount of unreacted reagent is titrated. Thiocyanogen reacts quantitatively with oleic acid but with only one of the two double bonds of linoleic add and with two of the three double bonds of linolenic acid. 

A description of an apparatus for titrating liquid NH3 solutions with standardized NH3 solutions is given by Zintl, Goubeau and Dullenkopf ClO]. Furthermore, similar devices for work with liquefied gases have been proposed by Juza, Schmitz-DuMont, F. Seel, G. W. Watt and others. A selectionof the latest literature on the subject is given in D-O], The reader should also refer to the preparation of thiocyanogen in Part n, as well as to the section on Carbonyls and Nitrosyls in Part III.
