| Sulfabenz is the intermediates of sulfonylurea herbicide, which can be used for synthesis of tribenuron-methyl, metsulfuron-methyl, Sulfometuron-methyl, etham-etsulfuronmethyl. N-methyl triazine is important intermediates of tribenuron-methyl. Tribenuron-methyl is a new type of sulfonylurea herbicide which is of high efficiency, low toxicity, the long hold an effect, low residue and its features are broad spectrum efficiency, long validity, and high safety.This design is a project for fine chemical industry, Sulfabenz can get through the reaction of the methanol, saccharine and sulphuric acid together, and then through the ring cleavage reaction. Acetonitrile and chlorine gas are reacted, then through the ring-closure reaction, replaced by sodium methoxide and monomethyl amine, N-methyl triazine can be got after the centrifugal separation.The technology of the project is advanced level in domestic, which focuses on energy-saving and consumption-reducing in the design process and strengthen the measures relating to occupational safety and healthã€fire protectionã€environmental protection, which reaches the relevant regulations, norms and standards of The State.The project which produces less waste is able to meet the requirements of the discharge after treatment. And meanwhile, it doesn’t produce residue and exhuast, and little influence are on the surrouding environment.The reliable safety measures of the project are practical. |
