Taw qhia
Dicyclohexyl disulfide yog cov organic sulfur compound. Nws yog xim tsis muaj xim rau daj oily kua nrog lub zog vulcanizing tsw.
Dicyclohexyl disulfide feem ntau yog siv los ua cov roj hmab accelerator thiab vulcanization crosslinker. Nws tuaj yeem txhawb cov roj hmab vulcanization cov tshuaj tiv thaiv, kom cov khoom siv roj hmab muaj elasticity zoo heev thiab hnav tsis kam, thiab feem ntau yog siv los tsim cov khoom siv roj hmab. Nws kuj tseem siv tau los ua ib qho nruab nrab thiab catalyst hauv organic synthesis.
Ib txoj hauv kev zoo rau kev npaj ntawm dicyclohexyl disulfide yog ua rau cyclohexadiene nrog sulfur. Raws li cov xwm txheej tsim nyog, ob lub sulfur atoms yuav tsim cov sulfur-sulfur bonds nrog ob daim ntawv cog lus ntawm cyclohexadiene, tsim cov khoom siv dicyclohexyl disulfide.
Kev siv dicyclohexyl disulfide xav tau qee cov ntaub ntawv kev nyab xeeb. Nws yog khaus thiab tej zaum yuav ua rau muaj kev tsis haum rau ntawm daim tawv nqaij. Kev tiv thaiv tsim nyog xws li hnab looj tes, tsom iav, thiab lwm yam, yuav tsum tau hnav thaum siv. Tsis tas li ntawd, nws yuav tsum tau khaws cia kom deb ntawm qhov hluav taws kub thiab qhov cua sov, khaws cia rau hauv qhov chaw txias, qhuav, thiab tsis txhob sib cuag nrog oxidants, acids thiab lwm yam tshuaj tiv thaiv kom tsis txhob muaj tshuaj lom. Thaum tuav lossis khaws cia, yuav tsum ua raws li cov txheej txheem kev nyab xeeb.
