As the project leader, he completed the national "863" plan and the key project of China Petroleum Science and Technology "Synthesis of Diphenyl Carbonate by Transesterification of Dimethyl Carbonate with Phenol instead of Highly Toxic Phosgene", with a fund of 6,543,800 yuan. The activity of DMC and the conversion rate of phenol were improved by using new efficient tin-titanium composite catalyst and process strengthening technology such as reaction separation and integration. The key technology verification test of 1 1,000 tons/year has been completed, and the technology with independent intellectual property rights has been formed, which can provide software packages for industrialized devices, break through the technical blockade of foreign countries to China, and solve the key technology of polycarbonate (PC) diphenyl carbonate industrialization in China. Now it has passed the national "863" and China petroleum acceptance. This technology has attracted the attention of more than 20 large domestic enterprises and foreign companies such as Bayer and LG. The project has entered the pilot stage of 5000 tons/year, with a three-year implementation period and a total investment of 80 million yuan. After the production, the annual sales will increase by 3 10/00000 yuan, and the profit and tax will be 65 million yuan. The industrialization of this project can accelerate the industrialization process of polycarbonate (PC) in China, promote the progress of cleaner production technology in the carbonate industry, and promote the formation of dimethyl carbonate, diphenyl carbonate and polycarbonate industrial chains with an output value of 654.38+000 billion yuan.
In terms of clean production technology of MDI, HDI and other isocyanates, we have obtained completely independent intellectual property coverage. Among them, the synthesis of MDI by urea route was funded by the Ministry of Science and Technology of 6.5438+0.8 million yuan, and the funding of Chinese Academy of Sciences, the Ministry of Science and Technology and related enterprises of 5 million yuan was further implemented. The progress of the preliminary work has been synchronized with similar foreign technologies, and a pilot MDI project of 6,543.8+0,000 tons/year was started in cooperation with China Petroleum with a capital of 30 million yuan.
