Title:
CATALYST FOR SELECTIVELY REDUCING SPINOSAD J AND PROCESS USING SAME
Document Type and Number:
WIPO Patent Application WO/2023/236534
Kind Code:
A1
Abstract:
Provided is a catalyst for selectively reducing spinosad J, relating to the technical field of spinosad preparation. The weight of active components of the catalyst accounts for 1%-10% of the weight of the catalyst, and the active components are selected from Pd, Pt, Rh, Ru, and Ir; the active components at least comprise two metals, the first metal is one selected from Pd, Pt, or Rh, and the remaining metal is any one or more selected from Pd, Pt, Ru, and Ir. According to the catalyst, hydrogen is used for reaction for 5-10 h under the conditions of 0.05-0.5 MPa and 10-80°Ϲ, such that a 5, 6-position double bond on a spinosad J four-membered ring lactone in a spinosad J/L mixture can be reduced, with a 13, 14-position double bond on the spinosad J four-membered ring lactone and spinosad L not reduced. The conversion efficiency, the selectivity, and the yield of the catalyst are higher, and the cost is lower.
