摘要:
Apparatus and processes are provided for forming epoxide compounds. In one embodiment, a process for the manufacture of an epoxide is provided including adding an oxidant, a water-soluble manganese complex and a terminal olefin to form a multiphasic reaction mixture, reacting the terminal olefin with the oxidant in the multiphasic reaction mixture having at least one organic phase in the presence of the water-soluble manganese complex, separating the reaction mixture into the at least one organic phase and an aqueous phase, and reusing at least part of the aqueous phase. The invention is also related to a device for performing the above process.
摘要:
A floor pan for high-speed trains is disposed below a car floor and implemented as a stand encased by a protective floor and has lateral carrier walls with side plates fastened thereon. The floor pan provides protection against damage by ballast stones to the under-floor space in which the equipment is stored.
摘要:
The present invention relates to a novel process for the production of coated filaments for subsequent application as print in extrusion-based 3D printers, e.g. FDM printers (fused deposition modelling printers). The filaments are coated in a separate process outside of the printer, and can also be used in a conventional extrusion printer. The present invention further relates to the coating device for application of the coating to the filament and to a roll containing the coated filaments.
