Technology research and development: Based on reasonable resource allocation, cost saving and consumption reduction, Jiachi chemical uses carbon monoxide gas produced by gasification unit in Chemical Industrial Park to produce acetic acid, acetic anhydride and other products. The raw materials required for production and public works such as steam, water, electricity and sewage treatment all rely on the park. There is no harmful waste gas and solid waste discharge in the production process, and the composition of waste water pollution is simple and easy to treat, After simple treatment, it enters the sewage treatment plant in the park, which is a new environmentally friendly chemical technology without environmental pressure. The technology of acetic acid and acetic anhydride project is advanced. The technology of carbonyl synthesis of acetic acid and production of acetic anhydride by pyrolysis is the technology with independent intellectual property rights in China, which is at the international leading level. The operation is safe and reliable, the investment cost is saved by 1 / 3, and the production cost can be reduced by more than 20% compared with the same type of projects. It has obvious competitive advantage.

Naphthalene can be obtained from coal tar or petroleum fractions. At present, the deep processing ability of naphthalene is low. 2,6-dan is synthesized from cheap and abundant naphthalene by alkylation reaction, and then 2,6-ndca is prepared by oxidation, so as to open up the technical route of naphthalene alkylation and oxidation to prepare 2,6-ndca. Jiachi chemical naphthalene production project develops a new technology of 2,6-ndca from naphthalene by alkylation and oxidation, which meets the needs of deep processing and clean utilization of coal tar products in China. It is a process route with great industrial application prospect.
