摘要
PROBLEM TO BE SOLVED: To provide an acrylic acid manufacturing catalyst superior in catalyst performance, capable of manufacturing acrylic acid stably and in a high yield for a long period of time, and a preparation method suitable for preparing the catalyst, and also provide an acrylic acid manufacturing method using the catalyst. ;SOLUTION: A carrier demonstrating 10,000 Ωcm (25°C) water resistivity or more after treatment is used. In a treatment process, 300 ml carrier is filled in a 500 ml conical beaker and dried at 120°C for two hours, and then (water absorption volume+220) ml pure water is added and heated at 90°C for 30 minutes under the normal pressure. The water absorption volume is represented by a formula: water absorption volume = A/B. In the formula, A = 300 (ml) ×filling density (g/ml) × water suction rate (wt.%)/100 and B = water density (g/ml)γ.;COPYRIGHT: (C)2000,JPO
