Mawu Oyamba
Mankhwalawa ndi C6H8O4S, omwe amatchedwa TDGA. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
Thiodiglycolic anhydride ndi madzi achikasu opepuka komanso onunkhira kwambiri. Ikhoza kusungunuka muzitsulo zambiri za organic, monga mowa, ethers ndi esters.
Gwiritsani ntchito:
Thiodiglycolic anhydride amagwiritsidwa ntchito ngati reagent yamankhwala, makamaka popanga mankhwala ndi zosungunulira. Amagwiritsidwa ntchito kwambiri m'minda ya mphira, pulasitiki ndi utoto, ndipo nthawi zambiri amagwiritsidwa ntchito pokonzekera zopangira, antioxidants ndi plasticizers.
Njira:
Thiodiglycolic anhydride akhoza kukonzedwa ndi zochita za sodium sulfure kolorayidi (NaSCl), acetic anhydride (CH3CO2H) ndi trimethylamine (N(CH3)3). Mayankhidwe ake enieni ndi awa:
NaSCl CH3CO2H N(CH3)3 → C6H8O4S NaCl (CH3)3N-HCl
Zambiri Zachitetezo:
Thiodiglycolic anhydride imakwiyitsa ndipo imatha kuyambitsa kutupa kwa maso ndi khungu kwambiri. Njira zodzitetezera ziyenera kuchitidwa panthawi yogwiritsira ntchito, monga kuvala magolovesi, magalasi ndi zovala zodzitetezera. Panthawi imodzimodziyo, onetsetsani kuti akugwiritsidwa ntchito pamalo abwino komanso kupewa kupuma mpweya wake. Mukakhudzana, yambani ndi madzi ambiri ndipo pitani kuchipatala mwamsanga. Posungira, Thiodiglycolic anhydride iyenera kusungidwa mu chidebe chosindikizidwa, kutali ndi moto ndi oxidizing agents.
