I-1,4-i-butanediol (i-BDO) Ngaba lulwelo olungenamibala olungenamibala otsalele ingqalelo kakhulu kumashishini ahlukeneyo ngenxa yepropathi eyahlukileyo kunye nokungasebenzi kakuhle. Ayisiyiyo kuphela le nto iguquguqukayo ngamanzi, esenza i-SOSTMP engaqhelekanga, kodwa inokusetyenziswa njenge-nonvoid antifreeze, i-mulsifier, kunye nearhente ye-hygroscopic. Izicelo zayo zihlala kumayeza amayeza kunye nokutya kunye ne-ornthesic synthesis, ezenza ukuba zibe yindawo ebalulekileyo yemichiza kwiinkqubo zokwenza izinto.
Enye yezona mpawu zibalulekileyo zeI-1,4-butadiolkukwazi kwayo ukwenza njengesinyibilikisi. Kwintsimi ye-chemistry ye-organic, izinyibilikisi zidlala indima ebalulekileyo ekuququzeleleni izinto kunye nokuchitha izinto. Ukungaqhelekanga kuka-BDO ngamanzi kuyakuvumela ukuba isetyenziswe kakuhle kwindlela yokuphendula yekhemikhali, ngakumbi kwi-chromatography yegesi apho ikhoyo njengolwelo oluninzi khona. Le ndawo ibalulekile ekuqaliseni nasemva kohlalutyo lomxube ontsonkothileyo, owenza i-BDO Isixhobo esixabisekileyo soochwephesha kunye nabaphandi.
Ukongeza kwindima yayo njengesinyibilikisi, i-1,4-i-Butadiol ibonwa ngepropathi yayo engeyiyo ityhefu, eyenza ilungele ishishini lokutya. Njengomntu wokutya, i-BDO inceda ukuzinza imixube eyayiza kwahlukile, njengeoyile namanzi. Le ndawo ibaluleke kakhulu xa ivelisa iisosi, iindlela kunye nezinye iimveliso zokutya ezifuna ukuthungwa nokubonakala. Iprofayile yokhuseleko ye-BDO iqinisekisa ukuba inokusetyenziswa ngaphandle kokubeka emngciphekweni wezempilo kubathengi, ukuphucula isibheno sayo kwizicelo zokutya.
Ukongeza, i-hygroscopic imeko yeI-1,4-butadioIyivumela ukuba ifune umswakama kwindalo esingqongileyo, isenza isithako esisebenzayo kwiintlobo ezahlukeneyo zokwenziwa. Le ndawo iyingenelo ikakhulu kumzi-mveliso wamachiza, apho ukugcina uzinzo kunye nokusebenza kakuhle kwezithako ezisebenzayo kubalulekile. Ngokongeza i-BDO kwiziko, abavelisi banokuthi bandise ubomi beshelufa kunye nokusebenza kweemveliso zabo, ukuqinisekisa ukuba bahlangabezana nemigangatho ephezulu yoshishino lwezeMpilo.
Ukusetyenziswa kweI-1,4-butadiolidlulela ngaphaya kokutya kunye namayeza. Kwi-synthesis ye-organisic, i-BDO yibhloko yesakhiwo yokuveliswa kweekhemikhali kunye nezixhobo. Iyakwazi ukwenza izinto zokugcina i-polymerizazazazaration ukuze iguqulwe ibe yi-Polybbutene Terephthane (PBT), i-thermoplastic isetyenziswe ngokubanzi kwimveliso yenxalenye yezinto ezizenzekelayo, izinto zombane kunye neemveliso zabathengi. Le tshintsho libalaselisa indima ye-BDO njengezinto eziphambili zokusebenza kakhulu zemveliso yanamhlanje.
Njengoko amashishini aqhubeka nokuvela kwaye afune izisombululo ezizinzileyo, imfuno yeekhemikhali ezingenatyhefu, ezisebenzayo ezinjenge-1,4-i-butanediol kulindeleke ukuba ikhule. Izicelo zayo kumacandelo ahlukeneyo njengokutya, amayeza kunye nezenzululwazi ezibonisa ukubaluleka kwayo kwiikomichiza zexesha elithile. Ngophando oluqhubekayo kunye nophuhliso, ukusetyenziswa kwezinto ezinokubakho ze-BDO kunokwenzeka ukuba kwandiswe, ukuhambisa indlela yeemveliso ezintsha kunye nezisombululo ezihlangabezana neemfuno zehlabathi eliguqukayo.
Ukuququmbela,I-1,4-butadiol yindawo engaqhelekanga edlala indima ebalulekileyo kumashishini ahlukeneyo. Iipropathi zayo njenge-solvent, ityhefu enganetyhefu, i-emulsifier kunye ne-hygroscopic arhente yenza ukuba ibe sisibonelelo esixabisekileyo kumashishini amayeza kunye nokutya kunye ne-synthesic synthesic. Njengoko siqhubeka nokuphonononga amandla alo le quand Expresiand, kucacile ukuba i-1,4-biediol iya kuqhubeka idlala indima ephambili kuphuhliso lwe-chemistry yale mihla kunye nemveliso.
