A simplified, smaller apparatus, capable of only modest yields (about 30%) is shown in Fig. 180. Hydrazine monochloride (two moles) Is placed in a 500-ml., two-neck, round-bottom flask. Tubes Tg and are closed off with rubber tubing and pinch clamps. 

Molybdenum can be determined using a kinetic spectrophotometric method based on the catalytic effect of molybdenum on the reduction of thionine by hydrazine monochloride in an acid medium. The reaction is monitored at 605 nm due to the decrease in absorbance of thionine. 

Hydrazine reduces potassium iodate in hydrochloric acid forming iodine monochloride, a reaction of analytical importance ... 

The 4- and 7-monochlorides 24 and 25 were reacted with hydrazine hydrate in a closed tube to give the hydrazino derivatives 26 and 27, as shown in Schemes 16 and 17, respectively <2002JHC889>. 

Titrimetric proceedures for the determination of KjEefCN) in alkaline media, also using hydrazine sulphate, have been desaibed. Determination of hydrazine and its derivatives is also important. A back-titration technique involving iodine monochloride in 5M-HC1 as the oxidant is simpler and of wider applicability than previous methods. ...
