Nhanganyaya
Dimethyl disulfide (DMDS) is an organic compound ine kemikari formula C2H6S2. Imvura isina ruvara uye inonhuwa zvinonhuwa.
DMDS ine kushandiswa kwakasiyana-siyana muindasitiri. Kutanga, inowanzoshandiswa se sulfidation catalyst, kunyanya muindasitiri yepetroleum kuvandudza kushanda kwekunatsa uye mamwe maitiro emafuta. Chechipiri, DMDS zvakare yakakosha fungicide uye zvipembenene zvinogona kushandiswa mukurima nekurima horticulture, sekudzivirira zvirimwa nemaruva kubva kuhutachiona uye zvipembenene. Mukuwedzera, DMDS inoshandiswa zvakanyanya sereagent mumakemikari synthesis uye organic synthesis reactions.
Nzira huru yekugadzirira kweDMDS ndeyekuita kwekabhoni disulfide uye methylammonium. Iyi nzira inogona kuitwa pakupisa kwepamusoro, kazhinji inoda kushandiswa kwezvinokonzeresa kufambisa maitiro.
Nezve ruzivo rwekuchengetedza, DMDS imvura inopfuta uye ine hwema hunonhuwa. Midziyo yekudzivirira yakakodzera senge magirovhosi, magirazi ekuchengetedza, uye zvipfeko zvekudzivirira zvinofanirwa kupfekwa panguva yekubata nekushandisa. Panguva imwecheteyo, inofanira kuchengetwa kure nemoto uye kupisa kunopisa kudzivirira moto kana kuputika. Kuchengetedza uye kutakurwa, DMDS inofanira kuiswa mumudziyo usingapindi mhepo yochengetwa munzvimbo inotonhorera, yakaoma, ine mhepo yakanaka, kure neoxidants uye zvitubu zvinopisa. Muchiitiko chekudonha kwetsaona, matanho anodiwa ekubvisa anofanirwa kutorwa nekukurumidza uye kufefetera kwakakodzera kunofanirwa kuve nechokwadi.
