1,4-Butanediol (BDO) lulwelo olunamafutha angenambala oluye lwatsala umdla omkhulu kumashishini ahlukeneyo ngenxa yeempawu zawo ezizodwa kunye nokuguquguquka. Le khompawundi ayidityaniswanga nje namanzi kuphela, iyenza isinyibilikisi esigqwesileyo, kodwa isenokusetyenziswa njengesithinteli sokukhenkceza esingenatyhefu, i-emulsifier yokutya, kunye ne-hygroscopic agent. Usetyenziso lwayo lunwenwela kumashishini amayeza kunye nokutya kunye ne-organic synthesis, nto leyo eyenza ukuba ibe sisixhobo esibalulekileyo sokwenza imichiza kwiinkqubo zangoku zokuvelisa.
Enye yeempawu eziphawulekayo ze1,4-butanediolkukukwazi ukusebenza njengesinyibilikisi. Kwinkalo ye-organic chemistry, izinyibilikisi zidlala indima ebalulekileyo ekuququzeleleni ukusabela kunye nokunyibilika kwezinto. Ukungahambi kakuhle kwe-BDO namanzi kuyivumela ukuba isetyenziswe ngokufanelekileyo kwiintlobo ezahlukeneyo zeekhemikhali, ngakumbi kwi-chromatography yerhasi apho isebenza njengolwelo olumileyo. Le propati ibaluleke kakhulu ukwahlula kunye nohlalutyo lwemixube enzima, okwenza i-BDO ibe sisixhobo esibalulekileyo kwiikhemisti kunye nabaphandi.
Ukongeza kwindima yayo njenge-solvent, i-1,4-butanediol iyaqatshelwa ngenxa yeempawu zayo ezingenayo inetyhefu, eyenza ibe yinto efanelekileyo kwishishini lokutya. Njenge-emulsifier yokutya, i-BDO inceda ukuzinzisa imixube ebinokwahlula, njenge-oyile namanzi. Le propati ibaluleke kakhulu xa uvelisa i-sauces, i-condiments kunye nezinye iimveliso zokutya ezifuna ukuthungwa okufanayo kunye nokubonakala. Iprofayili yokhuseleko ye-BDO iqinisekisa ukuba ingasetyenziswa ngaphandle kokubeka imingcipheko yempilo kubathengi, iphakamisa ngakumbi isibheno sayo kwizicelo zokutya.
Ukongeza, uhlobo lwe-hygroscopic ye1,4-butanediol ivumela ukuba ithathe umswakama kwindalo, iyenze isithako esisebenzayo kwiintlobo ezahlukeneyo zokuqulunqa. Le propati inenzuzo ngokukodwa kwishishini lamachiza, apho ukugcina ukuzinza kunye nokusebenza kwezinto ezisebenzayo kubalulekile. Ngokongeza i-BDO ekuqulunqweni, abavelisi banokwandisa ubomi beshelufu kunye nokusebenza kweemveliso zabo, baqinisekise ukuba bahlangabezana nemigangatho ephezulu yoshishino lwezempilo.
Ukuguquguquka kwe1,4-butanediolidlulela ngaphaya kokutya kunye namayeza. Kwi-organic synthesis, i-BDO yibhloko yokwakha ukuveliswa kweekhemikhali ezahlukeneyo kunye nezixhobo. Iyakwazi ukuphendulwa kwe-polymerization ukwenzela ukuba iguqulwe ibe yi-polybutylene terephthalate (PBT), i-thermoplastic esetyenziswa ngokubanzi kwimveliso yezixhobo zemoto, izixhobo zombane kunye neemveliso zabathengi. Olu tshintsho luqaqambisa indima ye-BDO njengesandulela semathiriyeli eyimfuneko yokusebenza okuphezulu kwimveliso yanamhlanje.
Njengoko amashishini aqhubeka nokuguquka kwaye afune izisombululo ezizinzileyo, imfuno yeekhemikhali ezingenayo inetyhefu, ezininzi ezisebenzayo ezifana ne-1,4-butanediol kulindeleke ukuba zikhule. Ukusetyenziswa kwayo kwiinkalo ezahlukeneyo ezinjengokutya, amayeza kunye nenzululwazi yezixhobo ibalaselisa ukubaluleka kwayo kwiinkqubo zale mihla zemichiza. Ngophando oluqhubekayo kunye nophuhliso, ukusetyenziswa okunokwenzeka kwe-BDO kunokwenzeka ukuba kwandiswe, kuvula indlela yeemveliso ezivelisa izinto ezintsha kunye nezisombululo ezihlangabezana neemfuno zehlabathi elihlala litshintsha.
Ukuququmbela,1,4-butanediol yikhompawundi engaqhelekanga edlala indima ebalulekileyo kumashishini ahlukeneyo. Iipropati zayo njenge-solvent, i-antifreeze engeyona inetyhefu, i-emulsifier yokutya kunye ne-hygroscopic agent iyenza ibe sisixhobo esixabisekileyo kumashishini amayeza kunye nokutya kunye nakwi-organic synthesis. Njengoko siqhubeka sihlola amandla ale khompawundi eguquguqukayo, kuyacaca ukuba i-1,4-butanediol iya kuqhubeka idlala indima ebalulekileyo ekuphuhliseni i-chemistry yanamhlanje kunye neshishini.
