Yintoni i-blyyne Glycol? Uhlalutyo olubanzi lwale michiza
Yintoni i-butadiol? Igama le-butediol lisenokuvakala elingaqhelekanga kubantu abaninzi, kodwa i-butanediol (i-1,4-i-Brodineol, i-BDO) idlala indima ebaluleke kakhulu kwishishini lekhemikhali nakwimihla ngemihla. Eli nqaku liza kukunika uhlalutyo olucacileyo lwepropathi kunye nokusetyenziswa kwe-butadiol kunye nokubaluleka kwayo kumashishini ahlukeneyo.
I. Iipropathi zeekhemikhali kunye nolwakhiwo lwe-butadiol
Yintoni i-butadiol? Ukusuka kwindawo yemichiza yekhemikhali, i-butadiol yindawo ye-organic enamaqela amabini e-hydroxyl (-) kunye nefomula yekhemicamicali yeC4H10O2. Yinto engenamibala, i-viscous fluity enesifo esihle, esinokuchithwa kwiintlobo ngeentlobo zeesolloves ezifana namanzi, i-shoscoul, i-themictur, ifomula yekhemikhali i-C4H10O2. Ngenxa yendlela yayo yemolekyuli iqulethe amaqela amabini e-hydroxyl, i-butediol kwimpendulo yemichiza ibonisa ukuphinda isebenze, inokuthatha inxaxheba ekubekweni, i-ethe pheskotion, i-polycondikelelo.
Okwesibini, ukusetyenziswa okuphambili kwe-butadiol
Ukuhlola ukuba yintoni i-butinediol enokungahlukaniswa kwisicelo sayo semveliso. I-Butylene Glycol isetyenziswa ikakhulu kwimveliso yee-polymers, izinyibilikisi kunye nabanye abalulekileyo kwimichiza.
Imveliso yePolymer: I-Butadiol sisixhobo esibalulekileyo sokuveliswa kwemveliso yePolysurethane kunye ne-Polyester Retins. Kwimveliso yePolyurethane, isetyenziswa njengezinto ezinqwenelekayo zecandelo kunye nezinto ezithambileyo zokunika imveliso ye-elasticing elungileyo kwaye idle ukuxhathisa; Kwimveliso ye-polyester, i-Bylene Glycol yeyona nto iphambili kwimveliso ye-thermoplastic polyeester (umz. I-PBT) kunye ne-polyester engaqhelekanga.

Izinyibilikisi: Ngenxa yokusolula kwayo okuhle, i-Blylene Glycol ikwasetyenziswa njengesinyibilikisi kuluhlu olubanzi lwezicelo kushishino lwe-elektroniki, iingubo, iicosmetics kunye ne-cosmetics. Ngakumbi kwi-cosmetics, i-Bylene Glycol isebenza njenge-himetiment kunye nesinyibiliki, ukunceda ukuphucula uzinzo kwimveliso kunye nexesha.

I-Comical Eprict: I-Bylene Glycol ngumnxibelelanisi obalulekileyo wokuveliswa kwe-tetrahydrofuran (i-thf) kunye ne-gambisa-byrolactoctor (i-GBL) esetyenziswayo kwimveliso yezibulala-zinambuzane, amayeza kunye nezinyibilikisi.

Okwesithathu, inkqubo yemveliso ye-butadiol
Ukuqonda ukuba yintoni i-butediol, kuya kufuneka ugxile kwinkqubo yayo yemveliso. Okwangoku, iindlela eziphambili zemveliso ze-butadinel zibandakanya:
Indlela yokufumana i-Aldehyde-Esona nkqubo isetyenziswayo esetyenziswayo, ngokusebenzisa i-prountences ye-acetaldehyde kunye ne-fioldehyde yokuvelisa i-1,3-dioxolane, kwaye emva koko i-hydlyliol ivelise i-bhyadiol. Le ndlela inezibonelelo zenkqubo eqolileyo kunye neendleko eziphantsi zexabiso.

Indlela ye-Ethylene Oxide: I-Ebanone ye-Othylene iphendulwa ngekharbon diokside phantsi kwesenzo se-catalyst ukuba ivelise i-vinyl carbonate, eyenziwe i-hydrolylid ukuba ivelise i-vingliol. Iimeko ezisabela ngale ndlela zilula, kodwa utyalomali kwizixhobo luphezulu.

Iv. Ithemba lentengiso le-butadiol
Ukuxoxa ngento oyithandayo, kuyimfuneko ukuphonononga amathuba ayo kwintengiso. Ngokukhulisa imfuno yehlabathi yezinto eziphezulu zokusebenza, imfuno yentengiso yeBhowadiol ikwakhula unyaka ngonyaka. Ingakumbi kwicandelo leemveliso ze-elektroniki, izithuthi zamandla amatsha kunye nemveliso enobuhlobo bokusingqongileyo, imfuno ye-butadiol iyathembisa.
Ngokuqhubela phambili kwetekhnoloji, uphando kunye nophuhliso lwe-bionediol esekwe kwi-bionediol nayo iqhubela phambili ngokuthe ngcembe. Ukusetyenziswa kwesi sibonelelo sivuselelekayo kuya kwandisa ngakumbi indawo yentengiso ye-butadine kwaye kunceda ukunciphisa ukuxhomekeka kwizixhobo zepetrochemical.
Ukuqukumbela
Yintoni i-butadiol? Ayisiyonto kuphela yekhemikhali yekhemikhali enoluhlu olubanzi lwezicelo kumashishini aliqela, kodwa itsalele ingqalelo kwiipropathi zayo ezibalaseleyo kunye nokungathathi ntweni. Kwixesha elizayo, ngenkqubela phambili kwezobuchwephesha kunye nokwandisa imfuno yentengiso, i-butadiol izakubonisa ixabiso layo elibalulekileyo kwimisimi nangaphezulu.
