The present invention provides a pyrolysis tube for manufacturing olefin which tube can improve a yield of olefin in a pyrolysis reaction of a hydrocarbon raw material. The pyrolysis tube (A) for manufacturing olefin includes a tubular base material () made of a heat resistant metal material and a dehydrogenating catalyst (A) which is supported on an inner surface of the tubular base material ().

Pyrolysis tube for manufacturing olefin and method for manufacturing dehydrogenating catalyst

The present invention provides a quinolone compound represented by General Formula (1) or a salt thereof, wherein Rrepresents a hydrogen atom, etc.; Rrepresents a hydrogen atom, etc.; Rrepresents a phenyl group optionally being substituted with one or more substituents, etc.; Rrepresents a halogen atom; Rrepresents a hydrogen atom or halogen atom; Rrepresents a hydrogen atom; and Rrepresents a hydroxyl group, etc. The quinolone compound have a functional improvement effect, which suppresses progression of neurological dysfunction by inhibiting the chronic progression of Parkinson's disease or protecting dopamine neurons from the disease etiology, thereby prolonging the period before first administration begins.

Quinolone compound and pharmaceutical composition

The present invention provides a quinolone compound that inhibits the chronic progression of Parkinson's disease or protects dopamine neurons from disease etiology, thereby suppressing the progression of neurological dysfunction, so as to prolong the period of time until L-dopa is administered while also improving neuronal function; the quinolone compound of the invention is represented by Formula (1): wherein:

A cracking tube () for use in thermal cracking furnaces for producing ethylene or the like has fins () formed on an inner surface thereof and inclined with respect to an axis of the tube for stirring a fluid inside the tube. The fins are arranged discretely on one or a plurality of helical loci, and the tube inner surface has regions (Z) wherein no fins are present over the entire axial length of the tube from one axial end of the tube to the other axial end thereof.
