Lili ndi zinthu zoyaka komanso zophulika. Chonde tcherani khutu ku malo osungira ndi mayendedwe. Ndikoyenera kuyikidwa pamalo ozizira komanso olowera mpweya wabwino, kutali ndi moto ndi okosijeni.Dimethyl disulfidendi mmodzi wa iwo. Mankhwala ake ndi ovuta. Iyenera kusungidwa mu migolo ya polyethylene kapena migolo ya aluminiyamu pakuyika.
Lili ndi zinthu zoyaka komanso zophulika. Chonde tcherani khutu ku malo osungira ndi mayendedwe. Ndikoyenera kuyikidwa pamalo ozizira komanso olowera mpweya wabwino, kutali ndi moto ndi okosijeni. Dimethyl disulfide ndi imodzi mwa izo. Mankhwala ake ndi ovuta. Iyenera kusungidwa mu migolo ya polyethylene kapena migolo ya aluminiyamu pakuyika. Kodi dimethyl disulfide imagwiritsidwa ntchito pati?
Ngakhale kuti dimethyl disulfide ili kutali ndi moyo wathu watsiku ndi tsiku, imaphatikizidwa ndi mankhwala ambiri ophera tizilombo ndi mankhwala ophatikizira ndipo imagwira ntchito yaikulu. Chosakaniza ichi chikhoza kupangidwa ndi zomwe dimethyl sulfate ndi sodium sulfide zimagwiritsidwa ntchito m'mafakitale ambiri ndi mabizinesi. Ndi madzi owala achikasu owonekera. Komabe, ogwira ntchito oyenerera ayenera kukhala patali ndi iwo, apo ayi adzanunkhiza fungo loipa komanso kukhala osamasuka.
Maonekedwe a thupi ndi mankhwala a dimethyl disulfide ndi ovuta. Malo osungunuka ndi -85 ° C, malo otentha ndi okwera pafupifupi 109 ° C, ndipo amasungunuka m'madzi ndi ethanol. Chosakaniza ichi ndi chowopsa. Onetsetsani kuti mutalikirane ndi zozimitsa moto. Ngati mwangozi wakhudza maso kapena khungu lanu, muyenera kuchitsuka ndi madzi othamanga ndikupita kuchipatala nthawi yake. Apo ayi, thupi lanu lidzavutika ndi zizindikiro zina m'tsogolomu. Zimakhalanso zovuta kuchira pakapita nthawi. Zigawo zambiri za thupi ndi makemikolo ndizovuta, koma pali zofanana m'mawonekedwe. Ngati simungathe kuwasiyanitsa kwakanthawi kochepa, muyenera kuwafunsa munthawi yake.
Pambuyo pomvetsetsa ntchito zazikulu za dimethyl disulfide, tiyenera kulabadira kwambiri. Pazinthu zambiri zosadziwika zakuthupi ndi zamankhwala, mutha kulozera ku malangizo kapena mapepala achitetezo kuti mudziwe za iwo.
