Kushandiswa
Dimethyl Disulfide (DMDS) imusanganiswa wemakemikari une fomura yeC2H6S2. Imvura isina ruvara ine hwema hwakasimba uye husingafadzi. Heano mamwe emashandisirwo ayo makuru:
1. Muindasitiri yepeturu: DMDS inoshandiswa zvakanyanya sechinhu chinowedzera chine sarufa mukuchenesa peturu. Inobatsira kuvandudza mashandiro ekubvisa sarufa nekushanda senzvimbo inobva sarufa. Inogona kuita nesimbi oxides pamusoro pezvinhu zvinobvisa sarufa, zvichiwedzera kushanda kwadzo uye kugadzikana kwadzo, uye nokudaro ichivandudza mwero wekubvisa zvinhu zvine sarufa muzvigadzirwa zvepeturu.
2. Muindasitiri yemakemikari: Chinhu chakakosha pakugadzira mishonga yakasiyana-siyana ine sarufa. Semuenzaniso, inogona kushandiswa kugadzira methanethiol, iyo inoshandiswazve mukugadzira mishonga yezvipembenene, mishonga, nemamwe makemikari akanaka. DMDS inogonawo kushandiswa mukugadzira mimwe mishonga ine sarufa ine heterocyclic, iyo ine mashandisirwo akakosha mumunda wekugadzirwa kwemishonga yeorganic.
3. Semushonga wekufukisa: Nekuda kwechepfu yayo kuzvipembenene netupukanana, DMDS inogona kushandiswa semushonga wekufukisa tupukanana nefungus muzviyo zvakachengetwa, mumatura, uye mumagreenhouse. Inogona kuuraya tupukanana nefungus zvakasiyana-siyana, ichibatsira kuchengetedza zvigadzirwa zvekurima zvakachengetwa uye kudzivirira kupararira kwezvirwere.
4. Mundima yezvemagetsi: DMDS inoshandiswa muindasitiri yesemiconductor kune mamwe maitiro akadai se chemical vapor deposition (CVD). Inogona kushandiswa kuisa sarufa - ine mafirimu matete, ayo anoshandiswa mukugadzirwa kwezvishandiso zvemagetsi zvakaita se transistors nema sensors.
5. Mukuongorora kemesitiri: DMDS inogona kushandiswa senzira yekubvisa ma "derivatization" mukuongorora kemesitiri. Inogona kuita zvimwe zvinhu mumakemikari e "organic compounds" kuti igadzire ma "derivatives" ane hunhu huri nani hwe "chromatographic" kana "spectroscopic", zvichiita kuti zvive nyore kupatsanurwa uye kuonekwa kwema "compounds" aya. Semuenzaniso, inogona kushandiswa mukuongorora mafuta acids nemamwe makemikari e "organic" ne "gas chromatography" - "mass spectrometry" (GC - MS).

Nguva yesherufu: Mwedzi makumi maviri nemana kubva pazuva rekugadzirwa kwayo, yakachengetwa munzvimbo inotonhorera yakaoma isina chiedza chezuva, mvura.
Imba yekuchengetera zvinhu ine mhepo, Inoomesa zvinhu zvishoma, Yakaparadzaniswa nezvinokonzera makemikari, maasidhi.
