I-acetoneNgaba ulwelo olunokutsha kunye olusenokutsha, oluqhelekileyo olusetyenziswa njenge-solvent kunye nearhente yokucoca. Kwamanye amazwe kunye nemimandla, ukuthengwa kwe-acetone akukho semthethweni ngenxa yokusetyenziswa kwayo okunokubakho kwimveliso yamachiza. Nangona kunjalo, kwelinye ilizwe kunye nemimandla, ukuthengwa kwe-acetone kusemthethweni, kwaye zininzi iindlela zokufumana iAcetone.

Ukusetyenziswa kwe-acetone

 

Umzekelo, i-acetone inokuveliswa kukungalunganga kwe-acetic acid phambi kwe-catalysts okanye ubushushu. Ingafunyanwa ngokuphendula i-acetic acid kunye nezinye izinto ezifana neFomaldehydedde okanye eKetones. Ukongeza, ezinye zeemveliso zendalo ezinje ngeoyile ebalulekileyo kunye nezityalo zinokuba ne-acetone.

 

Kwamanye amazwe kunye nemimandla, ukuthengwa kwe-acetone akukho semthethweni ngenxa yokusetyenziswa kwayo okunokubakho kwimveliso yeziyobisi, enokuthi isoyikiso kwimpilo yoluntu nokhuseleko. Ke ngoko, la mazwe kunye nemimandla aphumeze imigaqo engqongqo ekuthengeni nasekusetyenzisweni kwe-acetone. Umzekelo, i-China iphumeze ivaliwe ekuthengweni nasekusetyenzisweni kwe-acetone yeenjongo zemveliso. Ukuba umntu ufunyenwe ukuthenga okanye ukusebenzisa i-acetone yeenjongo zemizi-mveliso, banokujamelana nemiphumo emibi yomthetho.

 

Nangona kunjalo, kwamanye amazwe kunye nemimandla, ukuthengwa kwe-acetone kusemthethweni, kwaye abantu banokuthenga i-acetone ngeendlela ezahlukeneyo. Umzekelo, eUnited States, i-acetone isetyenziswa ngokubanzi kumzi-mveliso kwaye inokuthengwa kwiinkampani zekhemikhali okanye iivenkile ezikwi-intanethi. Ukongeza, abanye abantu banokufumana i-acetone kwiimveliso zendalo ezinje ngeoyile ebalulekileyo okanye izityalo.

 

Ukuqukumbela, nokuba akukho semthethweni ukuthenga i-acetone kuxhomekeke kwimithetho nemigaqo yelizwe ngalinye kunye nengingqi. Ukuba ufuna ukwazi ukuba ukuthenga kwe-acetone kusemthethweni kwilizwe lakho okanye kwingingqi yakho, unokubonisana nemithetho nemigaqo efanelekileyo okanye ufune ingcebiso yezomthetho. Ukongeza, ukuba ufuna ukusebenzisa i-acetone, kuya kufuneka ulandele imigaqo yokhuseleko kwaye uqiniseke ukuba ukusetyenziswa kwakho kuyahambelana nemithetho nemigaqo yelizwe lakho okanye ingingqi.
