When SiO〓-NH〓-Rh-Co complex was used to catalyze the hydroformylation of methyl methacrylate, an optimal conversion of 93.4% and optimal selectivity of 84.4% for the normal aldehyde were both obtained at Rh/Co ratio of 2/1, which were both higher than that catalyzed by SiO〓-SiNH〓-Rh and SiO〓-Si-NH〓-Co momometallic catalysts. Clearly a synergistic action between Rh and Co atoms presented in the complex.

The result shows that the viscosity was improved with the increase of the molecular mass of the product, the viscosity at 100℃ was between 17.827.6 mm^2/s, the viscosity index was more than 125, solidifying point was below -27℃, the oxidative stability was also improved with the increase of the molecular mass of the product. The biodegradabilities of complex esters were more than 70%. The value of PB was 784 N, the value of wear diameter was 0.41 mm, the temperature of thermal decomposition was above 250℃. The complex esters can be used as excellent green lubricants.
