1.Nā waiwai kemika:
ʻO ka wai aniani melemele māmā.He pilau pilau.ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai a hiki ke hui pū ʻia me ka ethanol, ether, a me ka acetic acid.
2. Ke kumu:
Hoʻohana ʻia ma ke ʻano he passivating agent no nā solvents, catalysts, pesticide intermediates, coking inhibitors, etc. Dimethyl disulfide reacts with cresol to produce 2-methyl-4-hydroxy anisulfide, a laila condenses me O, O-dimethyl phosphoryl sulfide chloride i loko o ka Chemicalbook alkaline ka waena e loaʻa ai ka Fenthion.He insecticide phosphorus organik maikaʻi a haʻahaʻa loa kēia me nā hopena hoʻomalu maikaʻi loa i nā mea hoʻoheheʻe raiki, nā ʻiʻo soybean, a me nā larvae gadfly.Hiki ke hoʻohana ʻia ma ke ʻano he lāʻau lapaʻau lāʻau e hoʻopau i nā ilo pipi a me nā makika pipi.
3.Production hana:
① Loaʻa ia ma ka hopena o Dimethyl sulfate a me ka sodium sulfide.E hoʻohui i ka pauka sulfur i loko o ka solution Sodium sulfide ma lalo o ka hoʻoulu ʻana, e hoʻokiʻekiʻe i ka mahana i 80-90 ℃, e hana no 1h, a e hoʻohaʻahaʻa i ka mahana o Chemicalbook ma kahi o 30 ℃;Hoʻokuʻu ʻia ʻo Dimethyl sulfate i loko o ka ipu aniani, hoʻomau ka hopena no 2h, a laila distilled, kū no ka waiho ʻana.Ma hope o ka hoʻokaʻawale ʻana i ka waiʻona alkali pau, loaʻa ka huahana i hoʻopau ʻia e ka distillation.
②Hoʻohui ʻia ʻo Dimethyl disulfide e ke ʻano Dimethyl sulfate i ka ʻoihana.
Na2S+S → Na2S2Na2S2+(CH3) 2SO4 → CH3SSCH3+Na2SO4
E hoʻokomo i ka sodium sulfide paʻa a me ka wai i loko o ka ipu hao, wela iā lākou, e hoʻomalu i ka mahana ma 50 ~ 60 ℃ e hoʻoheheʻe i ka sodium sulfurized Chemicalbook, a laila e hoʻohui i ka sulfur equimolar i loko o nā pahu, mālama i ka mahana no 1h, hoʻomaha i 45 ℃, hoʻomaka. e hoʻokuʻu i ka Dimethyl sulfate, e mālama i ka mahana hopena ma waena o 40 ~ 45 ℃, e mahana no 1h ma hope o ka hoʻohui ʻana, a laila e hoʻopau i ka huahana Dimethyl disulfide.Eia kekahi, hiki ke hoʻohui ʻia ʻo Dimethyl disulfide e ke ʻano methyl mercaptan.
③Hoʻopuka ʻia e ka hopena o ka iodomethyl magnesium a me Disulfur dichloride.Hoʻokumu ʻia ia e ka hopena o ka sodium disulfide me ka sodium methylsulfate.Hoʻomākaukau ʻia ka Methyl Sodium thiosulfate ma ka hana ʻana i ka Bromomethane me Sodium thiosulfate, a laila hoʻomehana.
4.Storage a me ka halihali 'ano:
ʻO ka ventila a me ka maloʻo haʻahaʻa haʻahaʻa o ka hale waihona;E kūʻai kaʻawale mai nā oxidants a me nā waikawa
5.mea kinai ahi
ʻO ka pauda maloʻo, ke one maloʻo, ka carbon dioxide, ka huʻa, 1211 mea kinai
I kēia manawa, ke hāʻawi mau nei ʻo Jinan ZhongAn Industry Co., Ltd i ka DMDS i nā mākeke nui.I Kepakemapa o kēia makahiki, e hoʻonui ʻo Jinan ZhongAn Industry Co., Ltd i kā mākou laina hana e hoʻokō i nā pono o nā mea kūʻai aku.Hoʻokipa mākou i nā mea kūʻai mai ka honua holoʻokoʻa e nīnau iā mākou.Ua loaʻa i kā mākou hui ka palapala hōʻoia ISO9001.E ʻoluʻolu e hōʻoia i ka maikaʻi o ka huahana.
Ka manawa hoʻouna: Iulai-26-2023
