Taw qhia
Dipropyl disulfide. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
1. Cov tsos mob: Dipropyl disulfide yog xim tsis muaj xim rau lub teeb daj crystalline lossis hmoov hmoov.
2. Solubility: yuav luag insoluble hauv dej, soluble hauv organic solvents xws li cawv, ethers thiab ketones.
Siv:
1. Roj hmab accelerator: Dipropyl disulfide feem ntau yog siv los ua ib qho accelerator rau roj hmab, uas tuaj yeem ua rau cov roj hmab vulcanization tuaj yeem txhim kho lub zog thiab tiv thaiv kev laus ntawm cov roj hmab vulcanization.
2. Rubber antifungal tus neeg sawv cev: Dipropyl disulfide muaj kev ua haujlwm zoo los tiv thaiv mildew, thiab feem ntau ntxiv rau cov khoom siv roj hmab los tiv thaiv qhov tshwm sim ntawm pwm thiab lwj.
Txoj kev:
Dipropyl disulfide feem ntau yog npaj los ntawm hydrolysis cov tshuaj tiv thaiv ntawm dipropyl ammonium disulfide. Ua ntej, dipropyl ammonium disulfide yog reacted nrog cov tshuaj alkaline (xws li sodium hydroxide) kom tau dipropyl disulfide, uas yog crystallized thiab precipitated nyob rau hauv acidic tej yam kev mob, thiab ces cov khoom kawg yog tau los ntawm pom thiab ziab.
Cov ntaub ntawv kev nyab xeeb:
1. Dipropyl disulfide yog ib qho khaus khaus thiab yuav tsum tsis txhob sib cuag ncaj qha ntawm daim tawv nqaij thiab qhov muag.
2. Thaum ua tiav thiab siv dipropyl disulfide, yuav tsum tau saib xyuas kev tiv thaiv kev tiv thaiv, xws li hnav cov hnab looj tes tiv thaiv thiab tsom iav, thiab xyuas kom muaj cua zoo.
3. Thaum khaws cia, tsis txhob sib cuag nrog cov oxidants thiab cov kua qaub muaj zog kom tsis txhob muaj kev phom sij txaus ntshai.
4. Thaum siv, yuav tsum tau ua raws li cov lus qhia txog kev nyab xeeb rau kev siv kom nyab xeeb.
