Title:
FILLER FOR VAPOR-PHASE REACTOR
Document Type and Number:
Japanese Patent JP2005238225
Kind Code:
A
Abstract:
To provide a filler 1 for vapor-phase reactor which has an excellent durability, doe not deteriorate even when being used continuously for a long period and does not cause mass reduction due to volatilization.
The filler 1 for vapor-phase reactor comprises alumina having an aluminum content ≥90% in mass fraction expressed in terms of oxide. For example, the specific surface area is ≤1 m2/g. The filler 1 for vapor-phase reactor is used by being filled into a vapor-phase reactor (2) as filler. In the vapor-phase reactor (2), a raw material compound (A), for example, hydrogen chloride and oxygen are allowed to react with each other at a temperature ≥200°C and hydrochloride is obtained as a reactant (B).
