I-Sodium P-TOLueenulfinate inezinhlobonhlobo zokusetshenziswa, ikakhulukazi ekuhlolweni kwe-organic. Okunye ukusetshenziswa kwayo okuvamile kufaka phakathi:
I-1.organic Synthentis reagent: Isetshenziswa kakhulu njenge-ejenti ye-sulfonylating ekuhlolweni kwama-sulfonamides namanye amakhompiyutha sulfonyl.
2
I-3. I-Catalyst: I-Sodium P-TOLueeesulfinate ingasebenza njenge-catalyst ekuphendukeni okuthile kwamakhemikhali ukukhuthaza ukwakheka kwemikhiqizo oyifunayo.
I-4. Ukukhiqiza amakhemikhali okuphakathi: Kusetshenziswa njengomphakathi ekukhiqizweni kwamakhemikhali ahlukahlukene kanye nemithi.
I-5. I-Chemistry yokuhlaziya: Ingasetjenziswa futhi ukuthola izicelo zokuhlaziya njengokutholwa kanye nokuncishiswa kwamakhompiyutha athile.
I-6. Isetshenziswa njengokusakaza udayi omenyezeli, futhi esetshenziswa njenge-ejenti yokwelapha izinto ezibonakalayo.
Kuyancibilika e-ethanol, amanzi kanye ne-ether.
Kugcinwe endaweni eyomile, enomthunzi, enomoya opholile. I-Sodium P-TOLueesulfite kufanele igcinwe ngaphansi kwale mibandela elandelayo ukuqinisekisa ukuqina nokusebenza kwayo:
1. Indawo epholile neyomile: gcina endaweni epholile neyomile, kude nomswakama nokushisa ukuvikela ukonakaliswa.
2. Isitsha se-Airtight: Sigcine esitsheni somoya ukuvikela umoya kanye nomswakama kusuka ekuthinteni ikhwalithi yayo.
3. Gwema ukukhanya: Uma kungenzeka, gcina ezitsheni ezimnyama noma ze-opaque ukuze unciphise ukuvezwa kokukhanya, okungathinta nokuqina kwezinye izinhlanganisela.
4. Ilebula: qiniseka ukuthi iziqukathi zibhalwe kahle ngegama lamakhemikhali, okuhlushwa, nanoma yiluphi ulwazi lokuphepha olufanele.

1, inani: 1-1000 kg, kungakapheli izinsuku ezi-3 zokusebenza ngemuva kokuthola izinkokhelo
2, inani: ngaphezulu kwe-1000 kg, kungakapheli amasonto ama-2 ngemuva kokuthola izinkokhelo.
I-Sodium P-TOLueesulfinate ngokuvamile ibhekwa njengenobuthi obuphansi, kepha njengamakhemikhali amaningi, kufanele iphathwe ngokunakekelwa. Nazi ezinye izinyathelo zokuphepha:
1. Ubuthi: Akuyona into enobuthi kakhulu, kepha isangenza ukucasuka esikhunjeni, emehlweni naseqeshweni lokuphefumula ngemuva koxhumana.
2. Ukusingathwa
3. Ukuphefumula kanye nokungena: Gwema ukuphefumula uthuli noma umphunga futhi ungangeni. Qinisekisa ukuthi indawo yomsebenzi inomoya omuhle.
I-4. Ishidi ledatha yokuphepha ezibonakalayo
I-5. Isitoreji: Njengoba kushiwo ngaphambili, gcina endaweni epholile neyomile kude nezinto ezingahambelani.
