Sichuan Ruibai Electronic Chemicals and related projects plan to construct Phase 2 first

Thread Content

The electronic chemicals and related projects of Sichuan Ruibai New Energy Materials Co., Ltd. will be implemented in two phases. Phase 1 mainly includes production facilities for acetic acid, methyl acetate, ethyl acetate, anhydrous ethanol, and related supporting facilities, while Phase 2 plans to build production facilities for electronic-grade esters and carbonates, along with corresponding supporting facilities. At present, the construction details for Phase 1 are still under refinement. However, given the high demand for electronic-grade acetates and carbonates in the southwestern region, the company intends to launch Phase 2 first in order to gain a competitive edge in the market. In the second phase, using purchased acetic acid, methanol, ethanol, n-butanol, n-propanol, and dimethyl carbonate as raw materials, the production capacity will be 50,000 tons per year of electronic-grade methyl acetate, 150,000 tons per year of electronic-grade ethyl acetate, 50,000 tons per year of electronic-grade propyl acetate, 50,000 tons per year of electronic-grade butyl acetate, 30,000 tons per year of electronic-grade methyl ethyl carbonate, 10,000 tons per year of electronic-grade diethyl carbonate, and 60,000 tons per year of electronic-grade dimethyl carbonate. Meanwhile, 10,000 tons per year of industrial-grade methyl acetate, 30,000 tons per year of industrial-grade ethyl acetate, 10,000 tons per year of industrial-grade propyl acetate, 10,000 tons per year of industrial-grade butyl acetate, and 1,054 tons per year of industrial-grade diethyl carbonate will be produced as by-products. Process technology for electronic-grade methyl acetate: Electronic-grade methyl acetate is produced by the esterification method. Electronic-grade ethyl acetate is produced using the reactive distillation method. Electronic-grade propyl acetate is produced by an esterification reaction using n-propanol and acetic acid as raw materials. Continuous processes are used in industrial production, mainly including an esterification unit, a dehydration unit, and a product purification and distillation unit. Electronic-grade butyl acetate is produced through an esterification reaction using n-butanol and acetic acid as raw materials. Continuous production processes are used in industrial manufacturing, mainly including an esterification unit, a dehydration unit, and a product purification and distillation unit. Electronic-grade carbonates are produced by transesterification of dimethyl carbonate with ethanol to yield methyl ethyl carbonate and diethyl carbonate, followed by purification. The relationship between production facilities and products is as follows.
