Butyl octanol is an important raw material for the synthesis of fine chemical products,low-pressure carbonylation is the main industrial process at present,and its core catalyst is rhodium(triphenylphosphine)carbonylacetylacetonate(ROPAC). The preparation process of ROPAC catalyst and the results of industrial side-line experiments were introduced.The problems in the preparation of ROPAC catalyst was solved by industrial scale-up production experiment.The total yield of two-step synthesis was over 98%.The mass fraction of chlorine ion in ROPAC catalyst was less than 0.005%.Relying on the 450 kt/a butyl octanol unit of Tianjin Bohua Yongli Chemical Co.,Ltd.,the domestic ROPAC catalyst was successfully used to replace imported catalyst from the industrial side-line test.The self-made catalyst and the imported reference catalyst were operated for 520 h respectively under 100% load.The index of the self-made ROPAC catalyst was similar to that of the imported catalyst in terms of the propylene consumption in aldehyde production and the ratio of N/I and the content of polymer in catalyst mother liquor.The indexes of aldehyde products were qualified,the overall performance of the self-made ROPAC catalyst was comparable to that of the imported catalyst.
Key words: oxo-synthesis; butyl octanol; rhodium; homogeneous catalysis; chlorion
