Omaka bomkhiqizo

Amakhodi Engozi	I-R12 – Ivutha Kakhulu R51/53 – Ukuba nobuthi ezintweni eziphila emanzini, kungabangela imiphumela emibi yesikhathi eside endaweni yasemanzini. R65 – Iyingozi: Ingadala umonakalo wamaphaphu uma igwinyisiwe R66 – Ukuchayeka kaningi kungabangela ukomisa kwesikhumba noma ukuqhekeka R67 – Izihwamuko zingadala ukozela kanye nesiyezi
Incazelo Yokuphepha	I-S9 – Gcina isiqukathi endaweni enomoya omuhle. S16 – Zigcine kude nemithombo yokuthungela. S29 – Ungathululi emiseleni. I-S33 - Thatha izinyathelo zokuphepha ngokumelene nokukhishwa okumile. I-S61 - Gwema ukudedelwa endaweni. Bheka imiyalelo ekhethekile / amaphepha edatha okuphepha. I-S62 – Uma igwinyisiwe, ungabangeli ukuhlanza; funa iseluleko sezokwelapha ngokushesha futhi ubonise lesi sitsha noma ilebula.

Isingeniso

I-Pentane. Izici zayo zimi kanje:

Ixubene nezinyibilikisi eziningi eziphilayo kodwa hhayi ngamanzi.

Izakhiwo Zekhemikhali: I-N-pentane iyi-aliphatic hydrocarbon evutha umlilo futhi inephuzu eliphansi lokukhanya kanye nezinga lokushisa elizenzakalelayo. Ingashiswa emoyeni ukuze ikhiqize isikhutha namanzi. Isakhiwo sayo silula, futhi i-n-pentane iyasebenza nezinhlanganisela ezivamile ze-organic.

Ukusetshenziswa: I-N-pentane isetshenziswa kabanzi ekuhlolweni kwamakhemikhali, ukulungiswa kwezinyibilikisi nezingxube ze-solvent, futhi iphinde ibe yimpahla ebalulekile embonini ye-petroleum.

Indlela yokulungiselela: i-n-pentane itholakala ngokuyinhloko ngokuqhekeka nokuguqula inqubo yokuhluza i-petroleum. I-petroleum by-products ekhiqizwa yilezi zinqubo iqukethe i-n-pentane, engahlukaniswa futhi ihlanzwe nge-distillation ukuze ithole i-n-pentane ehlanzekile.

Ulwazi lokuphepha: i-n-pentane iwuketshezi oluvuthayo futhi kufanele igcinwe kude namalangabi avulekile kanye namazinga okushisa aphezulu. Kufanele isetshenziswe endaweni enomoya omuhle futhi igweme ukuthintana nama-oxidizing agents aqinile. Ukuchayeka isikhathi eside ku-n-pentane kungase kubangele isikhumba esomile nesicasulayo, futhi kufanele kuthathwe izinyathelo zokuvikela ezifanele ezifana namagilavu namagilavu. Esimeni sokuhogela ngephutha noma ukuthinta isikhumba ne-n-pentane, funa usizo lwezokwelapha ngokushesha.

Okwedlule: I-Heptane(CAS#142-82-5)

Olandelayo: I-Octane(CAS#111-65-9)
