Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Amakhodi Engozi R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile.
R34 – Ibangela ukusha
I-R22 – Iyingozi uma igwinywe
Incazelo Yokuphepha S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.
S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu ​​kanye nokuvikela iso/ubuso.
Ama-ID e-UN 3261

Isingeniso

Ifomula yamakhemikhali ithi C6H8O4S, evame ukubizwa nge-TDGA. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:

 

Imvelo:

I-Thiodiglycolic anhydride iwuketshezi olungenambala ukuya kokuphuzi ngokukhanyayo olunephunga eliphunga elimnandi. Ingancibilika kuzincibilikisi eziningi eziphilayo, njengotshwala, ama-ether nama-ester.

 

Sebenzisa:

I-Thiodiglycolic anhydride ivame ukusetshenziswa njenge-reagent yamakhemikhali, ikakhulukazi ukuhlanganiswa kwamakhemikhali nezincibilikisi. Isetshenziswa kabanzi emkhakheni wenjoloba, ipulasitiki nopende, futhi ivame ukusetshenziswa ekulungiseleleni ama-catalysts, ama-antioxidants kanye nama-plasticizers.

 

Indlela:

I-Thiodiglycolic anhydride ingalungiswa ngokusabela kwe-sodium sulfur chloride (NaSCl), i-acetic anhydride (CH3CO2H) ne-trimethylamine (N(CH3)3). Ukusabela okuqondile kungokulandelayo:

I-NaSCl CH3CO2H N(CH3)3 → C6H8O4S NaCl (CH3)3N-HCl

 

Ulwazi Lokuphepha:

I-Thiodiglycolic anhydride iyacasula futhi ingabangela ukuvuvukala kwamehlo nesikhumba lapho kugxilwe kakhulu. Izinyathelo zokuzivikela ezidingekayo kufanele zithathwe ngesikhathi sokusetshenziswa, njengokugqoka amagilavu, izibuko nezingubo zokuzivikela. Ngesikhathi esifanayo, qiniseka ukuthi isetshenziswa endaweni enomoya omuhle futhi ugweme ukuhogela umhwamuko wayo. Uma uthintana, geza ngamanzi amaningi futhi ufune usizo lwezokwelapha ngokushesha ngangokunokwenzeka. Ngesikhathi sokugcina, i-Thiodiglycolic anhydride kufanele igcinwe esitsheni esivaliwe, kude nomlilo kanye nama-oxidizing agents.
