Mawu Oyamba
Diethyl disulfide (yomwe imadziwikanso kuti diethyl nitrogen disulfide) ndi gulu la organosulfur. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha diethyldisulfide:
Ubwino:
- Maonekedwe: Madzi opanda mtundu mpaka otumbululuka achikasu
- Kusungunuka: Kusungunuka mu zosungunulira organic monga ma alcohols, ethers, ethers ndi ketones, osasungunuka m'madzi.
Gwiritsani ntchito:
- Diethyldisulfide imagwiritsidwa ntchito ngati crosslinker, vulcanizing agent komanso difunctional modifier.
- Imakhudzidwa ndi ma polima okhala ndi magulu a amino ndi hydroxyl kuti apange maukonde olumikizirana kuti apititse patsogolo mphamvu ndi kukana kwa polima.
- Itha kugwiritsidwanso ntchito ngati zopangira zopangira, achromatics, antioxidants, antimicrobial agents, etc.
Njira:
- Diethyl disulfide nthawi zambiri imakonzedwa ndi ethanol reaction kuti ipange thioether. Pazimene zinthu, pamaso pa ethoxyethyl sodium catalysis, sulfure ndi ethylene yafupika ndi lithiamu aluminiyamu kupanga ethylthiophenol, ndiyeno etherification anachita ndi Mowa akukumana etherification anachita kupeza mankhwala diethyldisulfide.
Zambiri Zachitetezo:
- Diethyl disulfide ndi madzi omwe amatha kuyaka, chisamaliro chiyenera kutengedwa kuti chipewe kuyaka komanso kutentha kwambiri.
- Sungani malo olowera mpweya wabwino mukamagwiritsa ntchito ndi kusunga.
- Valani zida zodzitetezera zoyenera monga magolovu amankhwala, magalasi, ndi zovala zodzitchinjiriza mukamagwira ntchito.
