Chii chinonzi butyleyleye glycol? Kuongorora kwakazara kwemakemikari ino
Chii chinonzi butanedoliol? Iro zita rekuti Butaneddioly unonzwika kunge husina kujairika kuvanhu vazhinji, asi butanedoliol (1,4-butaneddiol, bdo) rinoita basa rakakosha kwazvo muindasitiri yemakemikari uye muhupenyu hwezuva nezuva. Chinyorwa ichi chinokupa kuongororwa kwakadzama kwezvivakwa uye kushandiswa kweButanediol uye kukosha kwayo mumaindasitiri akasiyana siyana.
I. Chemical Properties uye chimiro cheButanedoliol
Chii chinonzi butanedoliol? Kubva pamakemikari emakemikari ekuona, butanediol ndeye organic compound ine maviri hydroxyl mapoka (-OOH) uye fomu yemakemikari ndeye c4h10o2. Iyo isina ruvara, yeView mvura ine yakanaka solubility, iyo inogona kunyungudutswa mumvura soliety yakaita semvura, etc. Nekuda kweiyo moleky chimiro chine mapoka maviri ehuma
Chechipiri, iyo huru kushandiswa kweButanedolil
Kuongorora izvo butanedoliol hazvigone kuparadzaniswa kubva pakushandisa kwayo mune indasitiri. Asilyene Glycol inonyanya kushandiswa mukugadzirwa kwePolymers, solvent uye mamwe emakemikari akakosha emakemikari.
Polymer kugadzirwa: Butanedoliol chinhu chakakosha chigadzirwa chekugadzirwa kwePolyurethane uye polyester enzwi. MuPolyurethane kugadzirwa, inoshandiswa seketani yekuwedzera uye yakapfava chikamu chezvikamu zvekupa zvigadzirwa zvakanaka nekupfeka kurwisa; MuPolyester kugadzirwa, asi munyaradzi glycol chinhu chakakosha chigadzirwa chekugadzirwa kweTermoplastic polyester (eg pbt) uye isina kugadzikana polyester resin.

Solventts: Nekuda kwekunyepedzera kwayo solubility inoshandiswawo sechigadzika mune huwandu hwakawanda hwekushandisa muindasitiri yemagetsi, marara, magetsi uye cosmetics. Kunyanya mune cosmetics, asi mukyoroti glycol anoita kunge humbowo uye solvent, kubatsira kuvandudza kugadzikana kwechigadzirwa uye ductility.

Kemical Nyowani: Butylene Glycol Precursor yekugadzirwa kweTetrahydrofuran (THF) uye neGBL) Indasitiri yeChemaChical, nepo GBL iri yakakosha yepakati inoshandiswa mukugadzirwa yemishonga yekuuraya zvipembenene, mishonga yemishonga uye sol sol.

Chechitatu, iyo yekugadzira maitiro eButanedolil
Kunzwisisa izvo Butanedoliol iri, iwe zvakare unofanirwa kutarisa nezve maitiro ayo ekugadzira. Parizvino, nzira huru yekugadzira yeButanediol inosanganisira:
Aldehyde-doro nzira yekudonhedza: Izvi ndizvo zvinowanzo shandiswa kugadzira maitiro, kuburikidza nekukasira kweacetaldehyde uye formaldehyde kuburitsa 1,3-dioxolane, uye wobva wanyura kuti ubudise butaneddiol. Iyi nzira ine zvakanakira zviyero zvemukuru uye zvakaderera zvakabikwa mutengo.

Ethylene Oxide Nzira: Etleyone oxide inoitwa neCarbon Dioxide pasi pechiitiko cheChilyst kugadzira Vinyl carbonate, iyo ipapo hydrolysed yekugadzira butanedol. Maitiro ekuita emaitiro aya ari munyoro, asi iyo mari yekudyara mumidziyo yakakwira.

Iv. Musika tarisiro dzeButanedoliol
Kukurukura kuti chii chinonzi butanedoliol iri, zvinodikanwa kuti uongorore tarisiro yaro yemusika. Nekuwedzera kuri kudiwa kwepasi rose kwezvinhu zvakakwirira zvekuita, iyo musika inodiwa yeButanedolool iri kuendererawo gore rimwe nerimwe. Kunyanya mumunda wezvigadzirwa zvemagetsi, mota itsva idzva uye motokari dzinoshamwaridzana nedzimba, zvinodiwa neButanediol iri kuvimbisa.
Nekufambira mberi kwehunyanzvi, kutsvakisisa uye kusimudzira kwe bio-based butanedoliol kuri kufambira mberi zvishoma nezvishoma. Iko kushandiswa kweiyi nzvimbo yekuvandudza kunowedzera kuwedzera nzvimbo yemusika yeiyo butanedolu uye zvakare batsira kuderedza kutsamira pazvinhu zve petrochemical.
Mhedziso
Chii chinonzi butanedoliol? Haisi chete zvinhu zvakakosha zvemakemikari zvine huwandu hwenhandare dzakasiyana mumashandiro akati wandei, asi zvakare inokwezva kutarisisa kwemakemikari ayo akanaka emakemikari uye kuwanda. Mune ramangwana, nekufambira mberi kwehunyanzvi uye kudiwa kwemusika kuri kuwedzera, butanedoliol kunoratidza kukosha kwayo kwakakosha mumunda makawanda.
