Selelekela
Foromo ea lik'hemik'hale ke C6H8O4S, hangata e bitsoang TDGA. E latelang ke tlhaloso ea sebopeho sa eona, ts'ebeliso, tokiso le tlhaiso-leseling ea polokeho:
Tlhaho:
Thiodiglycolic anhydride ke mokelikeli o se nang 'mala ho isa ho o mosehla o bobebe o monko o hlabang. E ka qhibiliha ka li-solvents tse ngata tse phelang, tse kang joala, ethers le esters.
Sebelisa:
Thiodiglycolic anhydride e atisa ho sebelisoa e le reagent ea lik'hemik'hale, haholo-holo bakeng sa ho kopanya lik'hemik'hale le lihlapolli. E sebelisoa haholo masimong a rabara, polasetiki le pente, 'me hangata e sebelisoa ha ho etsoa li-catalysts, antioxidants le plasticizers.
Mokhoa:
Thiodiglycolic anhydride e ka lokisoa ke karabelo ea sodium sulfur chloride (NaSCl), acetic anhydride (CH3CO2H) le trimethylamine (N(CH3)3). Maikutlo a khethehileng ke a latelang:
NaSCl CH3CO2H N(CH3)3 → C6H8O4S NaCl (CH3)3N-HCl
Lintlha tsa Tšireletseho:
Thiodiglycolic anhydride e ea khopisa 'me e ka baka ho ruruha ha mahlo le letlalo libakeng tse phahameng. Mehato e hlokahalang ea tšireletso e lokela ho nkoa nakong ea tšebeliso, e kang ho roala liatlana, likhalase le liaparo tse sireletsang. Ka nako e ts'oanang, etsa bonnete ba hore e sebelisoa sebakeng se nang le moea o motle 'me u qobe ho hema mouoane oa eona. Haeba u ka kopana, hlatsoa ka metsi a mangata 'me u batle thuso ea bongaka kapele kamoo ho ka khonehang. Nakong ea polokelo, anhydride ea Thiodiglycolic e lokela ho bolokoa ka sejaneng se tiisitsoeng, hole le mollo le li-oxidizing agents.
