A copper silicate-based catalyst comprising copper and silica, wherein
- the copper silicate-based catalyst has a crushing strength of 40 N or higher, and
- the copper silicate-based catalyst has a Si elution ratio of 5 wt % or lower after an accelerated test according to Method 1:
- [Method 1]
- after immersing the copper silicate-based catalyst in a hydroxypivaldehyde (HPA) solution and conducting reaction at 180° C. for 6 hours under hydrogen atmosphere, the elution ratio of Si is calculated according to Equation 2:
