Nws muaj cov khoom tawg yooj yim thiab tawg. Thov xyuam xim rau qhov chaw khaws cia thiab kev thauj mus los. Nws yog qhov tsim nyog los muab tso rau hauv qhov chaw txias thiab qhov cua, kom deb ntawm hluav taws thiab oxidants.Dimethyl disulfideyog ib tug ntawm lawv. Nws cov tshuaj muaj pes tsawg leeg yog qhov nyuaj. Nws yuav tsum tau muab khaws cia rau hauv polyethylene chim los yog txhuas chim thaum ntim.

Nws yog qhov tsim nyog los muab tso rau hauv qhov chaw txias thiab qhov cua, kom deb ntawm hluav taws thiab oxidants. Dimethyl disulfide yog ib qho ntawm lawv. Nws cov tshuaj muaj pes tsawg leeg yog qhov nyuaj. Nws yuav tsum tau muab khaws cia rau hauv polyethylene chim los yog txhuas chim thaum ntim. Hauv thaj chaw twg yog dimethyl disulfide feem ntau siv?
Txawm hais tias dimethyl disulfide nyob deb ntawm peb lub neej txhua hnub, nws muaj nyob rau hauv ntau yam tshuaj tua kab thiab tshuaj intermediates thiab ua lub luag haujlwm tseem ceeb. Cov khoom xyaw no tuaj yeem tsim los ntawm cov tshuaj tiv thaiv ntawm dimethyl sulfate thiab sodium sulfide thiab siv rau hauv ntau lub lag luam thiab kev lag luam. Nws yog lub teeb daj pob tshab kua. Txawm li cas los xij, cov neeg ua haujlwm cuam tshuam yuav tsum nyob deb ntawm lawv, txwv tsis pub lawv yuav hnov ​​​​tsw tsw phem thiab ua rau lub cev tsis xis nyob.
Lub cev thiab tshuaj lom neeg cov khoom ntawm dimethyl disulfide yog qhov nyuaj. Lub melting point yog -85 ° C, boiling point yog siab txog 109 ° C, thiab soluble nyob rau hauv dej thiab ethanol. Cov khoom xyaw no yog qhov txaus ntshai heev. Nco ntsoov kom deb ntawm qhov hluav taws kub. Yog tias nws raug mob los ntawm koj lub qhov muag lossis tawv nqaij, koj yuav tsum tau ntxuav nws nrog dej ntws thiab nrhiav kev kho mob raws sijhawm. Txwv tsis pub, koj lub cev yuav raug kev txom nyem los ntawm qee cov tsos mob yav tom ntej. Nws kuj yog ib qho nyuaj rau rov qab los ntawm lub sij hawm. Ntau yam ntawm lub cev thiab tshuaj lom neeg yog qhov nyuaj, tab sis muaj qee qhov zoo sib xws hauv cov tsos. Yog tias koj tsis tuaj yeem paub qhov txawv ntawm lawv nyob rau lub sijhawm luv luv, koj yuav tsum sab laj nrog lawv raws sijhawm.
Tom qab nkag siab txog kev siv tseem ceeb ntawm dimethyl disulfide, peb yuav tsum ua tib zoo saib xyuas nws. Rau ntau yam tsis paub txog lub cev thiab tshuaj lom neeg, koj tuaj yeem xa mus rau cov lus qhia lossis cov ntaub ntawv kev nyab xeeb kom paub txog lawv.
