There is disclosed a process of producing an .alpha.-ketamide as an intermediate for use in the production of various alkoxyiminoacetamide compounds which are useful as fungicides. Also disclosed is an intermediate to be used in this process.
摘要:
A process is disclosed to produce an .alpha.-hydroxyiminophenylacetonitrile of the general formula [II]: ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and Z are each as defined in the specification, characterized in that a crude nitrile containing a phenylacetonitrile of the general formula [I]: ##STR2## wherein R.sup.1, R.sup.2, R.sup.3 and Z are each as defined in the specification, is reacted with an alkyl nitrite in the presence of a base, after which the reaction mixture is extracted with water and then the separated aqueous layer is neutralized with an acid. According to this production process, the desired .alpha.-hydroxyiminophenylacetonitrile can be produced with high purity, in high yield and with ease by extracting the reaction mass with water and then neutralizing the separated aqueous layer with an acid.

摘要:
A plug for manufacturing a seamless steel pipe is disclosed. The plug includes the surface layer made of molybdenum or molybdenum base alloy coming in contact with a workpiece to be drilled and the core covered with the surface layer. The surface of the core being in contact with the surface layer is formed uneven. According to the invention, the surface layer and the core are strongly joined together, and the life of the plug is elongated.
摘要:
A connector having a plug and a socket for receiving the plug. A first lock mechanism for locking the plug at a short inserting position, and a second lock mechanism for locking the plug at a long inserting position are provided. An indicator is provided for indicating a locked state by the second lock mechanism, thereby providing information that the plug is in an incomplete locking state.
