Synthesis of polymers:I-DEDC isetshenziswa kakhulu njenge-monomer noma i-Intermediate ku-synes of polysters nezinye izinto ze-polymer, ezingasetshenziswa kuzinhlelo zokusebenza ezahlukahlukene ezinjengezindwangu, ukunamathela kanye namapulasitiki.
I-Chemical Indermite:Kungumkhawulo obalulekile ekukhiqizweni kwemithi, ama-agrochemicals namanye amakhemikhali amahle, asiza ukuhlanganiswa kwama-molecule ayinkimbinkimbi ajwayelekile.
Umenzeli oxhumanisayo:I-DEDC ingasebenza njenge-ejenti exhumanisa ngokuxhumanisa ngokusabela okuthile kwamakhemikhali, okungakhulisa izakhiwo zemishini nezishisayo zezinto zokwakha.
Ucwaningo Nentuthuko:Ku-Academic and Industrial Research, i-DEFC isetshenziselwa ukuhlola izindlela ezintsha zokwenziwa, ukuthuthukisa amakhompiyutha amasha, kanye nezindlela zokuphendula.
Ukusebenza komhlaba:Ingasetshenziswa futhi ngezinqubo zokuguqulwa komhlaba ukwethula amaqembu athile asebenzayo angashintsha izakhiwo ezibonakalayo.

Kuvaliwe futhi kugcinwe endaweni enomoya opholile, eyomile.
1. Isitsha:Gcina i-DEDC ezitsheni zezindiza ezenziwe ngezinto ezihambisanayo (njengengilazi noma amapulasitiki athile) ukuvikela ukungcoliswa nokonakaliswa.
2. Ukushisa:Gcina isitsha endaweni epholile, eyomile kude nokukhanya kwelanga okuqondile nokushisa. Kungcono ukuyigcina emazingeni okushisa asekamelweni noma esiqandisini, kuya ngezincomo zomenzi.
3. Umswakama:Qiniseka ukuthi indawo yokugcina yomile njengoba umswakama ungathinta ukuqina kwe-compound.
4. Ilebula:Ukufaka ilebula ngokucacile iziqukathi ngegama lamakhemikhali, okuhlushwa, imininingwane eyingozi, kanye nosuku lokuthola ukuqinisekisa ukukhonjwa okufanele nokuphathwa.
5. Izindlela zokuphepha:Gwema kude nezinto ezingahambisani ezifana nama-ejenti aqinile we-oxidizing noma izisekelo. Qinisekisa ukuthi indawo yokugcina inomoya omuhle futhi ifakwe imishini efanelekile yokuphepha efana neziteshi zamehlo kanye nemikhosi yokuphepha.
6. Ukulawula ukufinyelela:Khawulela ukufinyelela ezindaweni zokugcina ukuze abasebenzi abaqeqeshiwe kuphela abaqonda izingozi ezihambisana namakhemikhali.
Ukulandela umthetho wokulawula:Qinisekisa ukuthi ukuthunyelwa kuhambisana nemithetho yasekhaya, kazwelonke, neyamazwe omhlaba ngokuphathelene nezinto eziyingozi. Lokhu kungafaka imihlahlandlela ebekwe ezinhlanganweni ezinjengoMnyango Wezokuvakasha (ichashaza) noma i-International Air Transport Association (IATA).
Ukupakishwa:Sebenzisa ukufakwa okufanele okuhambelana namakhemikhali. Isitsha kufanele sibe namandla, sivuze futhi simakwe ngokucacile ngegama lamakhemikhali, uphawu lwengozi, kanye nokuphatha imiyalo.
Amalebula:Qinisekisa ukuthi konke ukupakisha kunesivumelwano esifanele sezempi yezengozi, kufaka phakathi noma yimaphi amashidi wedatha yokuphepha efanelekile, ukwazisa abaphathi bezingozi ezingaba khona ezihambisana namakhemikhali.
Ukulawulwa kokushisa:Gcina izimo zokushisa ezifanele ngesikhathi sokuhamba ukuvikela ukonakala noma ukusabela. Gwema ukuvezwa kwamazinga okushisa aphezulu noma ukukhanya kwelanga okuqondile.
Gwema izinto ezingahambelani:Qinisekisa ukuthi i-DEDC ayithunyelwa kanye nezinto ezingahambelani ezifana nama-oxidants aqinile noma izisekelo njengoba lokhu kungadala ukusabela okuyingozi.
Imishini yokuzivikela (i-PPE):Abasebenzi ababambe iqhaza kwezokuhamba kufanele bagqoke i-PPE efanelekile, kufaka phakathi amagilavu, ama-goggles, kanye nezingubo zokuvikela ukunciphisa ubungozi bokuvezwa.
Izinqubo Eziphuthumayo:Ube nezinqubo eziphuthumayo ezikhona uma kwenzeka kuchitheka noma ingozi ngesikhathi sokuhamba. Lokhu kufaka phakathi ukuchitha ama-kits kanye nezinto zosizo lokuqala zilungele.
Ukuqeqeshwa:Qinisekisa ukuthi bonke abasebenzi ababandakanyeka ekusingatheni nasekuthuthayo Dedon baqeqeshelwe ngokwanele ezinqubweni zokuphepha kanye nokuphendula okuphuthumayo.
Ubuthi:I-DEDC ingaba yingozi uma ingene, inhaniwe, noma igxile esikhunjeni. Kuyacasula esikhunjeni, ngamehlo, kanye nepheshana lokuphefumula.
Carcinogenicicity:Yize idatha ethile kwi-carcinogenicity of devocc kungenzeka ingabhalwe kahle, amakhompiyutha amaningi anama-cheorde anemiphumela enokwenzeka ye-carcinogenic. Kunconywa ukuthi zithathwe njengezinto eziyingozi.
Ukuzwakala:Abanye abantu bangathola ukusabela komzimba noma ukuzwela ngemuva kokuxhumana ne-DEFC, okuholela ekuqhumeni noma ezinkingeni zokuphefumula.
Izindlela zokuphepha:Lapho usebenza nge-DEDC, imishini efanelekile yokuzivikela (i-PPE), efana namagilavu, ama-goggles, nokuvikelwa kokuphefumula, kumele kusetshenziselwe ukunciphisa ukubonakaliswa.
Ishidi ledatha yezokuphepha (SDS):Njalo bhekisa ekhasini elithile ledatha yokuphepha ukuze uthole i-4,4-hydroxybisbenzoyl chloride ukuthola imininingwane enemininingwane ngezingozi zayo zezempilo, izindlela zokuphepha ezinconyiwe, kanye nezinqubo zosizo lokuqala uma kuvezwa khona.
