An annual output of 800 tons of poly sulfonated polystyrene block copolymer synthesis process design
Abstract: According to the requirements of the mission，the design is the an annual output of 800 tons of poly sulfonated polystyrene block copolymer synthesis process design. The thesis writing time access to a large number of documents to understand the types and performance of block copolymer, and various methods for preparing the block copolymer, Special detailed research and analysis for poly sulfonated polystyrene block copolymer, understand the market situation and future prospects, Also described the use of its production process and production process equipment and its types. Also conducted a workshop process design of an annual output of 800 tons of poly sulfonated polystyrene block copolymer, write the details of the material balance and energy balance and workshop layout.
Poly sulfonated polystyrene block copolymer adopts the following processes: The styrene sulfonic acid and chlorine methyl styrene by copolymerization. Then add the styrene monomer, cuprous chloride catalyst, pyridine catalyst and get together under conditions of absence of oxygen. The solvent is evaporated, washing to remove catalyst, can obtain poly sulfonate polystyrene block copolymer. The production process is also taken into account in the low cost, low pollution, high performance, can be recycled to use concepts such as rational design and optimization of workshop, and draw the process flow chart of workshop layout.
Keywords: Block copolymers, styrene, polymerization, styrene sulfonic acid
