Izinto eziningi zokusetshenziswa zamakhemikhali zifihlakele emikhiqizweni eyahlukahlukene empilweni yansuku zonke, zisekela ukukhiqizwa kwezimboni futhi zithuthukisa ikhwalithi yokuphila kwabantu, futhi i-methyl propanol imele kakhulu phakathi kwabo. Abantu abaningi abajwayelene naleli gama lamakhemikhali, kodwa lingatholakala ezimbozweni zangaphakathi, ezinamathelayo, emikhiqizweni yokunakekelwa kwesikhumba yansuku zonke kanye nasepulasitikini yezimboni. Njengenhlanganisela yezinto eziphilayo enezakhiwo ezinhle kakhulu, i-methyl propanol isibe yinto eluhlaza eyisisekelo ebalulekile embonini yamakhemikhali, izinto zokwakha kanye namakhemikhali yansuku zonke, esebenza njenge-"ihhashi elisebenzayo lezimboni elingabonakali".
I-Methyl propanol, ebizwa ngokwesayensi ngokuthi i-2-methyl-1,3-propanediol (MPO) enefomula yama-molecule i-C₄H₁₀O₂, iyi-diol ethile ngokwesakhiwo. Ibonakala njengoketshezi olungenambala, olusobala nolune-viscosity ephansi olunokuthungwa okumsulwa, ukugeleza okuhle kanye nezici ezingenaphunga elincane, okubeka isisekelo sokusetshenziswa kwayo kabanzi emikhakheni eyahlukahlukene. Ngokuphathelene nezakhiwo zomzimba, inikeza ukusebenza okuphezulu: inephuzu lokuncibilika eliphansi elingu--91°C kanye nephuzu lokubila elingu-213°C, okwenza ikwazi ukumelana nobubanzi bokushisa obukhulu ngokumelana okuhle kakhulu nokushisa okuphansi kanye nokuqina kokushisa. Okwamanje, ine-solubility evelele, ixubene ngokuphelele nezinyibilikisi ezivamile ezifana namanzi, i-ethanol kanye ne-acetone, kuyilapho inganyibiliki ezinyibilikisini ezingezona ezi-polar okuhlanganisa i-benzene ne-cyclohexane, okwenza ifaneleke ekulungiseleleni izinhlelo ezahlukene zefomula.
Uma kuqhathaniswa notshwala obujwayelekile, i-methyl propanol inezinzuzo ezivelele kakhulu zezakhiwo zamakhemikhali ezizinzile neziphephile. Ayithambekele ekuboleni noma ekuwohlokeni ekushiseni kwegumbi, ngaphandle kokubola, ukuguquguquka okuphansi kanye nokusha okuphansi. I-flash point yayo icishe ibe yi-100°C, ihambisana nezindinganiso zokuphepha kwezimboni. Ngokuphathelene nesakhiwo sama-molecule, amaqembu ayo amabili ayinhloko e-hydroxyl kanye namaqembu e-methyl asemaceleni ayinika i-reactivity eguquguqukayo. Ingabamba iqhaza ekusabeleni kwamakhemikhali okuhlukahlukene njenge-esterification kanye ne-acetalization ukuze kuhlanganiswe izinto ze-polymer ezahlukahlukene. Inqubo yokusabela ilula futhi iyalawuleka ngaphandle kokukhiqiza inani elikhulu lezinto eziyingozi, ilinganisela ukusebenza kanye nobungane bemvelo - lokhu kuyinzuzo yayo eyinhloko ngaphezu kwezinto zokusetshenziswa zamakhemikhali ezifanayo.
Izuza ezimpahleni zayo ezisezingeni eliphezulu zomzimba nezamakhemikhali, i-methyl propanol ihlanganisa izimo eziningi zokusetshenziswa ekukhiqizweni kwezimboni kanye nemikhiqizo yendabuko. Embonini yezinto ze-polymer, iyinto eluhlaza eyinhloko yokwenza i-polyester ne-polyurethane. Uma isetshenziswa ekuhlanganisweni kwezinto, ingathuthukisa ngempumelelo ukuguquguquka, ukumelana nesimo sezulu kanye nokumelana nokushisa okuphansi kwemikhiqizo, inciphise i-viscosity yezinto, futhi yenze izembozo eziqediwe kanye nama-resin kube bushelelezi futhi kuhlale isikhathi eside. Isetshenziswa kabanzi ekukhiqizweni nasekukhiqizweni kwezembozo zezimboni, amapulasitiki obunjiniyela kanye nama-elastomer. Ngaphezu kwalokho, ingasetshenziswa ukulungiselela izithasiselo zepulasitiki ezifana nama-plasticizer nama-antioxidants, yandisa impilo yesevisi futhi ithuthukise ukuthungwa kwemikhiqizo yepulasitiki.
Ezimbonini zamakhemikhali ezinhle nezamakhemikhali zansuku zonke, i-methyl propanol isebenza njengesinyibilikisi esisezingeni eliphezulu esinobungani nemvelo kanye ne-humectant. Ngenxa yezakhiwo zayo ezithambile, ezingenabo ubuthi kanye ne-hydrophilic, ivame ukungezwa emikhiqizweni yokunakekelwa kwesikhumba kanye nezimonyo ukuze imanzise isikhumba, ilungise amafomula futhi ithuthukise umuzwa wesikhumba ngaphandle kokubangela ukucasuka kwesikhumba. Ngaphezu kwalokho, iyasebenza ekulungiseleleni ifomula yama-inki, izinamathiseli kanye nezinto zokuhlanza, ezingathuthukisa ukunamathela kanye nokufana kwemikhiqizo, zinciphise ukuguquguquka kwezinto eziyingozi, zithuthukise izinga lokuvikelwa kwemvelo kwemikhiqizo eqediwe, futhi zivumelane nezimo eziningi ezifana nokuhlobisa ikhaya, izinto zokubhala kanye nokukhiqizwa kwemboni elula.
Nakuba i-methyl propanol iyinto eluhlaza yamakhemikhali enobungozi obuphansi futhi isebenza kahle kakhulu, imininingwane ejwayelekile isadingeka ekusetshenzisweni nasekugcinweni kwansuku zonke. Imikhiqizo eqediwe equkethe i-methyl propanol iphephile ukuthintana okuvamile ngaphandle kokukhathazeka ngokweqile. I-methyl propanol emsulwa idinga ukugcinwa endaweni epholile futhi enomoya, kude nokushisa okuphezulu kanye namalangabi avulekile, futhi ihlukaniswe nama-oxidants aqinile. Emisebenzini yezimboni, izinyathelo zokuzivikela ezivamile kufanele zithathwe ukuze kugwenywe ukuthintana isikhathi eside kakhulu kanye nokugwinywa ngengozi. Imininingwane yokusebenza kwamakhemikhali eyisisekelo ingagwema ngempumelelo izingozi zokuphepha ezingaba khona.
Ngokuthandwa komqondo wamakhemikhali aluhlaza, izinto zokusetshenziswa zamakhemikhali ezinobuthi obuphansi, ezizinzile nezisebenzayo sezibe yinto eyinhloko yentuthuko yezimboni. Njengoba inobuchwepheshe bokukhiqiza obuvuthiwe, ukusebenza okuzinzile, ubungane bemvelo kanye nokuphepha, i-methyl propanol iye yathatha indawo kancane kancane kwezinye izinhlobo zotshwala ezivamile ezingcolisa kakhulu kanye nezingozi ezinkulu, kanti ububanzi bokusetshenziswa kwayo emakethe bukhula njalo. Inani layo lihlolwa njalo ekukhiqizweni kwezimboni zendabuko, embonini yamakhemikhali amahle aphezulu kanye nasembonini yamakhemikhali yansuku zonke eluhlaza.
Ekuphetheni, nakuba kubonakala sengathi kuyinto encane, i-methyl propanol iyinto eluhlaza ebalulekile kodwa enganakwa ohlelweni lwezimboni lwanamuhla. Ngokusebenza okuzinzile kanye nokuzivumelanisa nezimo okubanzi, ingena kuzo zonke izimpilo zethu, ithuthukisa buthule ikhwalithi yomkhiqizo kanye nezindinganiso zokuphila zabantu. Ukuqonda i-methyl propanol akukhona nje ukuqaphela into yamakhemikhali, kodwa futhi nokubona ubuhle obuyingqayizivele bamakhemikhali amahle anamuhla asebenza futhi ahlanganiswe nokuphila kwansuku zonke.
