Nhanganyaya
Iyo kemikari formula ndeye C6H8O4S, inowanzonzi TDGA. Inotevera rondedzero yehunhu hwayo, kushandiswa, kugadzirira uye ruzivo rwekuchengetedza:
Zvakasikwa:
Thiodiglycolic anhydride imvura isina ruvara kuenda kuchiedza yero uye ine hwema hunopinza. Inogona kunyungudutswa mune zvakawanda organic solvents, senge doro, ethers uye esters.
Shandisa:
Thiodiglycolic anhydride inowanzoshandiswa sekemikari reagent, kunyanya pakugadzirwa kwemakemikari uye zvinonyungudutsa. Inoshandiswa zvakanyanya muminda yerabha, mapurasitiki uye pendi, uye inowanzoshandiswa mukugadzirira kwezvinokonzera, antioxidants uye plasticizers.
Nzira:
Thiodiglycolic anhydride inogona kugadzirirwa nekuita kwe sodium sulfur chloride (NaSCl), acetic anhydride (CH3CO2H) uye trimethylamine (N (CH3) 3). Maonero chaiwo ndeaya anotevera:
NaSCl CH3CO2H N(CH3)3 → C6H8O4S NaCl (CH3)3N-HCl
Zvekuchengetedza
Thiodiglycolic anhydride inotsamwisa uye inogona kukonzera kuzvimba kwemaziso uye ganda pamwero wakanyanya. Matanho anodiwa ekudzivirira anofanirwa kutorwa panguva yekushandiswa, sekupfeka magirovhosi, magirazi uye zvipfeko zvinodzivirira. Panguva imwe cheteyo, iva nechokwadi chokuti inoshandiswa munzvimbo ine mhepo yakanaka uye kudzivisa kufema mhute yayo. Kana masangana, geza nemvura yakawanda uye tsvaga kurapwa nekukurumidza. Panguva yekuchengetedza, iyo Thiodiglycolic anhydride inofanira kuchengetwa mumudziyo wakavharwa, kure nemoto uye oxidizing agents.
