I-acetoneiyinhlanganisela yamakhemikhali esetshenziswa kabanzi enezinhlobonhlobo zezimboni nezasendlini. Ikhono layo lokuncibilikisa izinto eziningi kanye nokuhambisana kwayo nezinto ezihlukahlukene kuyenza ibe yisixazululo semisebenzi eminingi, kusukela ekususeni uwoyela ka-指甲 kuya ekuhlanzeni i-glassware. Kodwa-ke, iphrofayili yayo yokuvutha ngokuvamile ishiya abasebenzisi kanye nochwepheshe bezokuphepha ngokufanayo nemibuzo evuthayo. Ingabe i-acetone engu-100% iyavutha? Le ndatshana icubungula isayensi ngemuva kwalo mbuzo futhi ihlola ubungozi namaqiniso ahlobene nokusetshenziswa kwe-acetone emsulwa.

Ukuze siqonde ukuvutha kwe-acetone, kufanele siqale sihlole ukwakheka kwayo kwamakhemikhali. I-acetone iyi-ketone enekhabhoni emithathu equkethe kokubili umoya-mpilo nekhabhoni, izakhi ezimbili kwezintathu ezidingekayo ukuze kuvutha (eyesithathu i-hydrogen). Eqinisweni, ifomula yekhemikhali ye-acetone, i-CH3COCH3, iqukethe kokubili isibopho esisodwa nesikabili phakathi kwama-athomu ekhabhoni, enikeza ithuba lokusabela kwama-radical mahhala okungaholela ekushiseni.

Nokho, ngenxa yokuthi into iqukethe izingxenye ezivuthayo akusho ukuthi izosha. Izimo zokuvutha zihlanganisa umkhawulo wokugxila kanye nokuba khona komthombo wokuthungela. Endabeni ye-acetone, lo mkhawulo kukholakala ukuthi uphakathi kuka-2.2% no-10% ngevolumu yomoya. Ngaphansi kwalokhu kugxila, i-acetone ngeke ivutha.

Lokhu kusiletha engxenyeni yesibili yombuzo: izimo lapho i-acetone ishisa khona. I-acetone ehlanzekile, lapho ivezwe kumthombo wokuthungela njengenhlansi noma ilangabi, izovutha uma ukugxila kwayo kungaphakathi kwebanga lokuvutha. Kodwa-ke, izinga lokushisa elivuthayo le-acetone liphansi kakhulu uma liqhathaniswa namanye ama-fuel amaningi, okwenza kube mancane amathuba okuvutha ezindaweni ezishisa kakhulu.

Manje ake sicabangele imithelela yomhlaba wangempela yalolu lwazi. Ezilungiselelweni eziningi zasendlini nezimboni, i-acetone emsulwa ayivamile ukuhlangana nayo ekugxilweni okuphezulu ngokwanele ukuthi ingavutha. Kodwa-ke, ezinqubweni ezithile zezimboni noma ekusetshenzisweni kwe-solvent lapho kusetshenziswa khona ukugxila okuphezulu kwe-acetone, izinyathelo zokuphepha ezengeziwe kufanele zithathwe ukuze kuqinisekiswe ukuphepha. Abasebenzi abaphatha lawa makhemikhali kufanele baqeqeshwe kahle ekuphatheni ngendlela ephephile, okuhlanganisa nokusetshenziswa kwezinto ezikwazi ukumelana namalangabi kanye nokugwema okuqinile kwemithombo yokuthungela.

Sengiphetha, i-acetone engu-100% ingasha ngaphansi kwezimo ezithile kodwa kuphela lapho ukugxila kwayo kungaphakathi kwebanga elithile futhi kukhona umthombo wokuthungela. Ukuqonda lezi zimo nokusebenzisa izinyathelo ezifanele zokuphepha kungasiza ekuvimbeleni noma yimiphi imililo engaba khona noma ukuqhuma okuvela ngenxa yokusetshenziswa kwalesi sithako samakhemikhali esidumile.
