摘要： Unsymmetrical azonitriles of the formula, ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are independently straight- or branched-chain alkyl having 1 to 7 carbon atoms or alkoxy substituted straight- or branched-chain alkyl having 2 to 11 carbon atoms but at least one of R.sup.1 and R.sup.2 and at least one of R.sup.3 and R.sup.4 must be different, have good efficiency as initiator for polymerizations or copolymerizations of vinyl monomers. These unsymmetrical azonitriles can be prepared by oxidizing a corresponding unsymmetrical hydrazo compound.

摘要： A steam turbine power plant comprises a high-pressure turbine to be driven by steam generated by a steam generator, a first reheater for separating moisture from steam discharged from the high-pressure turbine and heating the steam, an intermediate-pressure turbine to be driven by the steam heated by the first reheater, a second reheater for heating exhaust steam discharged from the intermediate-pressure turbine, and a low-pressure turbine to be driven by the steam heated by the second reheater. The intermediate-pressure turbine discharges dry steam.
