Since the acceptance of Zhengzhou Automobile's vehicle import port in October 2014, the original imported Land Rover car port test business has been steadily advanced. Among them, the Zhengzhou returning trains from Hamburg on December 8 and 25, 2014, respectively carried 6 vehicles and 12 imported Land Rover vehicles, and arrived in Zhengzhou after running 1014 kilometers for 16 days. “Zhengzhou Port has become the most economical and convenient international logistics channel for European cars to enter the inland market.†Zhao Wenming, general manager of Zhengzhou International Land Development and Construction Co., Ltd. said.
At the same time, Zheng Ou Ban Lie also made breakthrough progress in the timeliness of the trip, and the running time of the trip was shortened from the original 16 days to 12 days.
Dye intermediates mainly benzene intermediates, toluene intermediates, naphthalene intermediates and anthraquinone intermediates four categories, in addition, there are some heterocyclic intermediates. The main intermediates in the production of the reaction process are nitration, sulfonation, halogenation, reduction, amination, hydrolysis, oxidation, condensation and so on. Synthesis of a complex structure of the intermediate often go through many unit processes, sometimes using different basic raw materials and different synthetic routes. For example, the production of p-nitroaniline, the initial nitration with benzene, reduced aniline, re-acetylation, nitration, hydrolysis of the synthetic route, this method of long production process, high cost. Has now switched to benzene chlorination, nitration, separation of nitrochlorobenzene, and then high pressure ammonia solution synthesis route. For the manufacture of dyes, pesticides or Pharmaceutical Intermediates, usually complex structure, often supporting the final product and production, smaller production, production and more use of intermittent operation. Some of the most widely used intermediates, such as nitrobenzene, aniline, chlorobenzene, phenol, etc., are usually produced in a large, integrated chemical plant with large production volumes and continuous operation in production.
