Dimethyl Disulfide (CAS:624-92-0) Ruzivo (CAS:624-92-0)

1.Hunhu hwemakemikari:

Mvura yero yakapfava inoonekera. Kune hwema hwakaipa. Hainyungudike mumvura uye inogona kusanganiswa ne ethanol, ether, uye acetic acid.

2. Chinangwa:

Inoshandiswa sechinhu chinonyungudutsa zvinhu zvinonyungudutsa, zvinokonzeresa, zvinouraya zvipembenene, zvinodzivisa coking, nezvimwewo. Dimethyl disulfide inobatana necresol kugadzira 2-methyl-4-hydroxy anisulfide, yozobatana neO, O-dimethyl phosphoryl sulfide chloride muChemicalbook alkaline medium kuti iwane Fenthion. Ichi mushonga wezvipembenene unoshanda uye une chepfu shoma une organic phosphorus zvipembenene une simba guru rekudzora pazvipfukuto zvemupunga, soya heartworms, uye gadfly larvae. Inogona zvakare kushandiswa semushonga wemhuka kubvisa honye dzemombe nenda dzemumadziro emombe.

3. Nzira yekugadzira:

①Inowanikwa nekuita kweDimethyl sulfate neSodium sulfide. Wedzera hupfu hwesarufa muSodium sulfide solution uchikurunga, wedzera tembiricha kusvika 80-90 ℃, ita reacting kweawa imwe, uye deredza tembiricha yeChemicalbook kusvika pa30 ℃; Dimethyl sulfate inodonhedzwa mukettle ye reaction, reaction inoenderera mberi kwemaawa maviri, uye yozonyungudutswa, ichimira kuti iite layering. Mushure mekuparadzanisa marara ealkali liquor, chigadzirwa chapera chinowanikwa ne distillation.

②Dimethyl disulfide inogadzirwa nenzira yeDimethyl sulfate mumaindasitiri.

Na2S+S → Na2S2Na2S2+(CH3) 2SO4 → CH3SSCH3+Na2SO4

Isa Sodium sulfide yakasimba nemvura mukettle yereaction, zvipise, dzora tembiricha pa50~60 ℃ kuti unyungudise sodium yeChemicalbook yakasanganiswa nesulfur, wobva wawedzera equimolar sulfur mumabatches, chengeta ichidziya kwe1 awa, itonhore kusvika 45 ℃, tanga kudonhedza Dimethyl sulfate, chengetedza tembiricha yereaction iri pakati pe40~45 ℃, chengeta ichidziya kwe1 awa mushure mekuwedzera, wobva wabvisa Dimethyl disulfide. Pamusoro pezvo, Dimethyl disulfide inogonawo kugadzirwa nenzira yemethyl mercaptan.

③Inogadzirwa nekuita kweiodomethyl magnesium neDisulfur dichloride. Inoumbwa nekuita kwesodium disulfide nesodium methylsulfate. Methyl Sodium thiosulfate inogadzirwa nekuita Bromomethane neSodium thiosulfate, yozodziiswa.

 

4. Hunhu hwekuchengetedza uye hwekufambisa:

Kufefetedza mhepo uye kuomesa imba yekuchengetera zvinhu pakupisa kushoma; Chengeta zvakasiyana nezvinokonzera ma oxidants nema acids

 

5.Mudzimisi wemoto

Hupfu hwakaoma, jecha rakaoma, kabhoni dhayokisaidhi, furo, chinhu chinodzima moto che1211

 

 

Parizvino, Jinan ZhongAn Industry Co., Ltd iri kuramba ichipa DMDS kumisika mikuru. MunaGunyana wegore rino, Jinan ZhongAn Industry Co., Ltd ichawedzera mutsetse wedu wekugadzira kuti igutse zvinodiwa nevatengi vakawanda. Tinogamuchira vatengi vanobva kumativi ese epasi kuti vatibvunze. Kambani yedu yakawanawo chitupa cheISO9001. Ndapota ivai nechokwadi chemhando yechigadzirwa.
