Butylene glycol ni iki? Isesengura ryuzuye ryiyi miti
Butanediol ni iki? Izina butanediol rishobora kumvikana nkutamenyereye abantu benshi, ariko butanediol (1,4-Butanediol, BDO) igira uruhare runini mubikorwa byimiti no mubuzima bwa buri munsi. Iyi ngingo izaguha isesengura rirambuye kumiterere nikoreshwa rya butanediol nakamaro kayo mubikorwa bitandukanye.
I. Imiterere yimiti nuburyo bwa Butanediol
Butanediol ni iki? Duhereye ku miti, butanediol ni urugimbu rufite amatsinda abiri ya hydroxyl (-OH) naho imiti yimiti ni C4H10O2. Ni ibara ritagira ibara, rifite ibara ryinshi rifite imbaraga zo gukemuka neza, rishobora gushonga mumashanyarazi atandukanye nkamazi, alcool, ketone, nibindi. Imiterere ya molekuline ya butanediol irimo amatsinda abiri ya hydroxyl, naho imiti ya C4H10O2. Kubera imiterere ya molekuline irimo amatsinda abiri ya hydroxyl, butanediol mumyitwarire ya chimique yerekana reaction nyinshi, irashobora kugira uruhare muri esterification, etherification, polycondensation nibindi bitekerezo byimiti.
Icya kabiri, ikoreshwa nyamukuru rya butanediol
Gucukumbura icyo butanediol idashobora gutandukanywa nuburyo bukoreshwa mu nganda. Butylene glycol ikoreshwa cyane cyane mu gukora polymers, umusemburo hamwe n’imiti ihuza imiti.
Umusemburo wa polymer: butanediol nigikoresho cyingenzi cyo gukora polyurethane na polyester. Mu musaruro wa polyurethane, ukoreshwa nkuwagura urunigi nibikoresho byoroshye kugirango ibicuruzwa bitangwe neza kandi birwanya kwambara; mu musaruro wa polyester, butylene glycol nigikoresho cyingenzi cyibanze cyo gukora polyester ya termoplastique (urugero PBT) hamwe na poliester idahagije.

Umuti: Bitewe no gukemuka kwiza, butylene glycol nayo ikoreshwa nkigishishwa muburyo butandukanye bwo gukoresha inganda za elegitoroniki, impuzu, ibikoresho byo kwisiga hamwe no kwisiga. Cyane cyane mu kwisiga, butylene glycol ikora nka humectant kandi ikemura, ifasha kuzamura ibicuruzwa no guhindagurika.

Abahuza imiti: Butylene Glycol nintangiriro yingenzi yo gukora tetrahydrofuran (THF) na gamma-butyrolactone (GBL) .THF ikoreshwa cyane mubikorwa byo hejuru, ibifata hamwe ninganda zimiti, mugihe GBL ari intera ikomeye ikoreshwa mubikorwa y'imiti yica udukoko, imiti n’imiti.

Icya gatatu, inzira yo gukora butanediol
Sobanukirwa na butanediol icyo aricyo, ugomba no kwibanda kubikorwa byayo. Kugeza ubu, uburyo nyamukuru bwo gukora butanediol burimo:
Uburyo bwa Aldehyde-alcool: Ubu ni bwo buryo bukoreshwa cyane mu gutanga umusaruro, binyuze mu guhuza acetaldehyde na formaldehyde kugira ngo habeho 1,3-dioxolane, hanyuma hydrolysed ikabyara butanediol. Ubu buryo bufite ibyiza byimikorere ikuze nigiciro gito cyibikoresho fatizo.

Uburyo bwa okiside ya Ethylene: Okiside ya Ethylene ikorwa na karuboni ya dioxyde de carbone ikorwa na catalizator kugirango ikore karubone ya vinyl, hanyuma hydrolysed ikabyara butanediol. Imiterere yuburyo bwubu buryo iroroshye, ariko ishoramari mubikoresho ni ryinshi.

IV. Ibyiringiro byisoko rya Butanediol
Muganira kuri butanediol icyo aricyo, birakenewe kandi gushakisha uko isoko ryifashe. Kubera ko isi igenda yiyongera ku bikoresho bikoreshwa neza, isoko rya butanediol naryo riragenda ryiyongera uko umwaka utashye. Cyane cyane mubijyanye nibicuruzwa bya elegitoronike, ibinyabiziga bishya byingufu hamwe n’ibidukikije byangiza ibidukikije, icyifuzo cya butanediol kiratanga ikizere.
Hamwe niterambere ryikoranabuhanga, ubushakashatsi niterambere rya bio-ishingiye kuri bioanediol nayo iratera imbere buhoro buhoro. Gushyira mu bikorwa aya masoko ashobora kuvugururwa bizakomeza kwagura isoko rya butanediol kandi binafasha kugabanya gushingira ku mutungo wa peteroli.
Umwanzuro
Butanediol ni iki? Ntabwo ari ibikoresho byingenzi bya shimi bifite imiti myinshi ikoreshwa mubikorwa bitandukanye, ariko kandi bikurura abantu kubintu byiza byimiti kandi bihindagurika. Mugihe kizaza, hamwe niterambere ryikoranabuhanga no kongera isoko ku isoko, butanediol izerekana agaciro kayo mubice byinshi.
