1,4-Butanediol (BDO) iwuketshezi olunamafutha angenambala oludonse ukunaka okukhulu ezimbonini ezahlukahlukene ngenxa yezakhiwo zalo eziyingqayizivele kanye nokuhlukahluka. Akukhona nje kuphela ukuthi le nhlanganisela ixubana namanzi, okuyenza ibe isincibilikisi esihle kakhulu, kodwa futhi ingasetshenziswa njengesinqamuleli esingenabuthi, i-emulsifier yokudla, kanye ne-hygroscopic agent. Ukusetshenziswa kwayo kuhlanganisa izimboni zemithi nokudla kanye ne-organic synthesis, okuyenza ibe i-reagent yamakhemikhali ebalulekile ezinqubweni zokukhiqiza zesimanje.
Esinye sezici eziphawuleka kakhulu ze1,4-butanediolyikhono layo lokusebenza njengesincibilikisi. Emkhakheni wamakhemikhali ezinto eziphilayo, izincibilikisi zidlala indima ebalulekile ekwenzeni kube lula ukusabela nasekuncibilikiseni izinto. Ukungahlangani kwe-BDO namanzi kuyivumela ukuthi isetshenziswe ngempumelelo ezinhlobonhlobo zokusabela kwamakhemikhali, ikakhulukazi ku-gas chromatography lapho isebenza njengoketshezi olumile. Lesi sakhiwo sibalulekile ekuhlukaniseni nasekuhlaziyeni izingxube eziyinkimbinkimbi, okwenza i-BDO ibe ithuluzi elibalulekile losokhemisi nabacwaningi.
Ngaphezu kwendima yayo njenge-solvent, i-1,4-butanediol iyaziwa ngezindawo zayo ezingenabuthi, okwenza kube kuhle embonini yokudla. Njenge-emulsifier yokudla, i-BDO isiza ukuzinzisa izingxube ezingase zihlukane, njengamafutha namanzi. Lesi sakhiwo sibaluleke kakhulu lapho kukhiqizwa amasoso, ama-condiments neminye imikhiqizo yokudla edinga ukuthungwa nokubukeka okungaguquki. Iphrofayili yokuphepha ye-BDO iqinisekisa ukuthi ingasetshenziswa ngaphandle kokufaka ubungozi bezempilo kubathengi, iphinde ithuthukise ukukhanga kwayo ezinhlelweni zokudla.
Ukwengeza, imvelo ye-hygroscopic ye1,4-butanediol ivumela ukuthi imunce umswakama emvelweni, iyenze ibe isithako esisebenzayo ezinhlobonhlobo zokubunjwa. Lesi sakhiwo sinenzuzo ikakhulukazi embonini yezemithi, lapho ukugcina ukuzinza nokusebenza kahle kwezithako ezisebenzayo kubalulekile. Ngokungeza i-BDO ekwakhiweni, abakhiqizi banganweba isikhathi seshelufu nokusebenza kwemikhiqizo yabo, baqinisekise ukuthi bahlangabezana nezindinganiso eziphakeme zomkhakha wezokunakekelwa kwempilo.
Ukuhlukahluka kwe1,4-butanediolidlulela ngalé kokudla kanye nemithi. Ku-organic synthesis, i-BDO iyisakhiwo sokukhiqiza izinhlobo zamakhemikhali nezinto zokwakha. Iyakwazi ukusabela kwe-polymerization ukuze iguqulwe ibe yi-polybutylene terephthalate (PBT), i-thermoplastic esetshenziswa kabanzi ekukhiqizeni izingxenye zezimoto, izingxenye zikagesi kanye nemikhiqizo yabathengi. Lolu shintsho lugqamisa indima ye-BDO njengesandulela esibalulekile esisebenza kahle kakhulu sokukhiqiza kwesimanje.
Njengoba izimboni ziqhubeka nokuthuthuka futhi zifuna izixazululo ezisimeme, isidingo samakhemikhali angenabuthi, asebenza ngezindlela eziningi njenge-1,4-butanediol kulindeleke ukuthi sikhule. Ukusetshenziswa kwayo emikhakheni eyahlukene njengokudla, imithi kanye nesayensi yezinto ezibonakalayo igqamisa ukubaluleka kwayo ezinqubweni zamakhemikhali zanamuhla. Ngocwaningo oluqhubekayo nokuthuthukiswa, ukusetshenziswa okungenzeka kwe-BDO kungenzeka kwande, kuvule indlela yemikhiqizo emisha nezisombululo ezihlangabezana nezidingo zomhlaba oguquguquka njalo.
Ekuphetheni,1,4-butanediol iyinhlanganisela engavamile edlala indima ebalulekile ezimbonini ezihlukahlukene. Izakhiwo zayo njenge-solvent, i-antifreeze engeyona enobuthi, i-emulsifier yokudla kanye ne-hygroscopic ejenti iyenza ibe yinsiza ebalulekile embonini yemithi neyokudla kanye nakuma-organic synthesis. Njengoba siqhubeka nokuhlola amandla ale nhlanganisela ehlukahlukene, kuyacaca ukuthi i-1,4-butanediol izoqhubeka idlala indima ebalulekile ekuthuthukisweni kwamakhemikhali nemboni yesimanje.
