DPG yɛ rɔba vulcanization promoters a ɛho hia sen biara no mu biako, a wɔde di dwuma titiriw wɔ abɔde ne nea wɔde yɛ rɔba mu.Ɛwɔ onyin a ɛyɛ papa wɔ vulcanized rɔba mu na ɛsan nso yɛ adwuma sɛ ade a ɛma thiazole, thiuram ne sulfonamide promoters.Wɔ chloroprene rɔba no mu Auxiliary agent ne nea ɛkeka ho, titiriw de di dwuma wɔ manufacture tae ne rɔba product ne nea ɛkeka ho wɔ rɔba sole.

Nneɛma titiriw a wɔyɛ de yɛ promoter DPG no bi ne cyanide chloride, metal oxide desulfurization ne oxidation desulfurization.Wɔn mu no, catalytic oxygen oxidation ne adeyɛ a ɛfata sen biara ma green chemistry.

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 na wɔde fra nsu mu, na wɔde ammonia kaa ho, oxygen faa mu, na wɔde catalytic oxidation reaction nyaa diphenyl guanidine.(3) Afei wɔde aduru no gu acid mu de yiyi nsu no mu. Afei wɔde alkali a ɛyɛ nsu no di dwuma de gu ade no mu na yiyi mu. Afei wɔde nsu pii hohoro nkyene pii a ɛwɔ ade no mu.Saa ɔkwan yi yɛ nea wɔde di dwuma wɔ amanne kwan so. Sɛnea ɛbɛyɛ a wɔbɛhwɛ ahu sɛ CA no bɛsakra wɔ adeyɛ no mu no, mpɛn pii no, ammonia nsu a ɛboro so no ho hia. Wɔ adeyɛ no mu no, ammonia gas ne oxygen yɛ mmerɛw sɛ ɛbɛyɛ afrafra a ɛpae, a ɛde ahobammɔ ho asiane kɛse ba.Bere koro no ara mu no, sɛnea ɛbɛyɛ a ahoɔhare a wɔde yɛ ade no bɛyɛ ntɛmntɛm no, ɛsɛ sɛ adeyɛ no ma nhyɛso dodow bi ba no, nhyɛso a ɛko tia nnwinnade no nso ho hia, bere tenten{11}}bere a wɔde yɛ adwuma bere tenten a nnwinnade no hwehwɛ no yɛ kɛse, mfiridwuma mu sikasɛm mu sikasɛm yɛ kɛse.

Afei nso, mprempren, synthesis process of promoter DPG titiriw gye kettle type reactor ma batch adwumayɛ, na batch no nya nkɛntɛnso kɛse wɔ adwumayɛfo adwumayɛ so, enti product no su yɛ prone to instability.Bere koro no ara, wɔ kettle oxidation nhyehyɛe no, dodow a ammonia feed kɛse ammonia feed, a ammonia ne oxygen no yɛ mmerɛw sɛ wɔbɛma kwan ma wɔayɛ explove, na eyi process risk. High, na ɛyɛ mmerɛw sɛ wubenya ɔhaw ahorow wɔ bere tenten-bere mu adwumayɛ mu.

Microchannel reactor no wɔ ɔfasuo pɔtee bi a ɛwɔ soro, afrafra ntɛmntɛm, mass transfer efficiency a ɛkorɔn a ɛwɔ ɔhyew a ɛkɔ baabi foforo, reaction tebea a ɛyɛ pɛ na atwetwe adwene pii a nhwehwɛmufo a wɔwɔ field of chemical synthesis, ne mass transfer a ɛkorɔn, ɔhyew transfer efficiency ma ayɛ reaction pii betumi ayɛ pɛpɛɛpɛ control, na afei to theory of instantaneous reaction, to increase the efficiency of the process of a process of a process safety and product has a product has a product have a process safety and product has.

Ɔkwan a wɔfa so yɛ vulcanization accelerator DPG no kɔ so yɛ nhwehwɛmu foforo.
