Espesipikasion:

DPG is one of the most important rubber vulcanization promoters, which is mainly used in natural and synthetic rubber.It has good aging resistance in vulcanized rubber and also ACTS as an activator of thiazole, thiuram and sulfonamide promoters.In the chloroprene rubber has the plasticizer, the plasticizer the function, is also produces the dye the raw material, the plastic product crosslinking agent, the temperature material and the building materials use the Auxiliary agent ken dadduma pay, kangrunaanna nga usaren iti manufacture tire ken ti goma a produkto ken dadduma pay iti goma a suela.

Dagiti kangrunaan a proseso ti panagpataud ti promotor a DPG ket mairaman ti cyanide chloride, metal oxide desulfurization ken oxidation desulfurization.Karaman kadagitoy, ti katalitiko nga oksihena nga oksidasion ket isu ti kaaduan a maibagay a proseso para iti berde a kimika.

At present, the industrialization methods of rubber vulcanization promoter DPG are using oxygen as oxidant, under the catalysis of copper acetate catalyst, the raw material diphenyl thiourea (CA) ammonia is oxidized to generate the promoter DPG.Specifically, (1) preparation of diphenyl thiourea by first mixing aniline with water and then reacting with carbon disulfide and sulfur;(2) diphenyl thiourea was mixed with Ti danum, ammonia ket nainayon, ti oksiheno ket naipasa babaen, ken ti diphenyl guanidine ket naala babaen ti katalitiko nga oksidasion a reaksion.(3) ti produkto ket kalpasanna ket marunaw iti asido tapno agsala kadagiti Dregs. Kalpasanna ti likido nga alkali ket mausar a mangpadaras ken mangsala iti produkto. Kalpasanna ti dakkel a kaadu ti asin iti produkto ket nabugguan babaen ti dakkel a kaadu ti danum.Daytoy a pamay-an ket maysa a relatibo a tradisional. Tapno masigurado ti conversion rate ti CA iti proseso ti produksion, sapasap a kasapulan ti nalabes a danum ti ammonia. Iti proseso ti panagpataud, ti gas ken oksihena ti ammonia ket nalaka a mangporma ti eksplosibo a panaglalaok, a mangpataud ti dakkel a peggad ti kinatalged.Iti isu met laeng a panawen, tapno mapapartak ti kapartak ti reaksion, ti proseso ti panagpataud ket kasapulan a mangipaay ti maysa a naikeddeng a kaadu ti presion, ti panagandur ti presion ti alikamen ket kasapulan pay, ti atiddog ​​a-Ti proseso ti panagpataray ti panagpataray dagiti kasapulan ti alikamen, ti panagpuonan ti industrialisasion ket dakkel.

In addition, at present, the synthesis process of promoter DPG mainly adopts kettle type reactor for batch operation, and the batch is greatly affected by personnel operation, so the product quality is prone to instability.At the same time, during the kettle oxidation process, the amount of ammonia feed is large, and the unreacted ammonia and oxygen are easy to form explosive mixture, which increases the process risk.At the same time, the manufacture cost of pressure reactor ket nangato, ken nalaka laeng ti maaddaan kadagiti parikut iti atiddog ​​a-panagpataray ti termino.

Microchannel reactor has a large specific surface area, fast mixing, high mass transfer efficiency of heat transfer, reaction conditions of uniform and has attracted many attentions of the researchers in the field of chemical synthesis, its high mass transfer, heat transfer efficiency to make a lot of reaction can realize accurate control, and then to the theory of instantaneous reaction, to increase the efficiency of the product in the process of synthesis, process safety and product quality has a great help.

Ti pamay-an ti agtultuloy a panagpataud ti vulcanization accelerator DPG ket kasapulanna ti kanayonan a panagsirarak.
