trans-2,3-Dimethylacrylic acid CAS 80-59-1
izinga
I-Trans-2,3-dimethacrylic acid iwuketshezi olungenambala. Ine-asidi futhi ingasabela ngezisekelo ukwenza usawoti ohambisanayo. Ingasabela ngobudlova ngomoya-mpilo wegumbi futhi ingase izishise ngokuzenzakalelayo. Ingase futhi isabelane nezinye izinsimbi ukwenza usawoti wensimbi ohambisanayo. I-Trans-2,3-dimethacrylic acid inokuncibilika okuhle futhi ingancibilika emanzini nasezincibilikisini eziphilayo. Embonini, ivame ukusetshenziswa njengendawo ephakathi lapho kuhlanganiswa izinto eziphilayo, futhi ingasetshenziswa ekulungiseni ama-polymers athile, amapulasitiki, kanye nezingubo.
Ukusetshenziswa kanye nezindlela zokuhlanganisa
I-Trans-2,3-dimethacrylic acid, eyaziwa nangokuthi i-methylisobutenic acid, iyi-unsaturated carboxylic acid equkethe amaqembu amabili e-methyl. Inohlu olubanzi lwezinhlelo zokusebenza.
I-Trans-2,3-dimethacrylic acid isetshenziswa njenge-monomer ekuhlanganiseni ama-polymers. Ingenziwa i-copolymerized namanye ama-monomers ngokusebenzisa ukusabela kwe-polymerization yamahhala, njenge-copolymerization nge-acrylic acid ne-methyl acrylate ukuze kutholwe i-methylisopropyl methyl acrylate copolymer. Lawa ma-polymers anezakhiwo ezinhle kumapende, ama-coatings, ama-adhesives, njll., futhi asetshenziselwa ukwandisa ukumelana nomthelela wemikhiqizo, ukunciphisa i-viscosity, njll.
Okwesibili, i-trans-2,3-dimethacrylic acid nayo ingasetshenziswa njengento ebalulekile ekuhlanganiseni kwe-organic synthetic. Amaqembu ayo amabili e-methyl ahlinzeka ngendawo esebenzayo yokusabela, futhi izinhlobonhlobo zezinto eziphilayo zingalungiswa ngokuqhubekayo kokusebenza kokuguqulwa kweqembu. Isibonelo, ngokusabela ngama-amine noma ama-alcohols, izinhlanganisela ezisebenzayo ze-biologically, njengezilawuli zokukhula kwezitshalo, zingahlanganiswa.
Indlela yokuhlanganisa ye-trans-2,3-dimethacrylic acid ijwayele ukulungiswa ngokusabela kwe-isobutylene nge-carbon monoic acid hydrate. I-Isobutylene iphendulwa nge-peracid positive iron ukuze kutholwe i-substrate methylisobutenic acid, ebese isabela nge-cuprous chloride eyeqile ukuze yakhe usawoti wangaphakathi, bese isabela ngotshwala ukuze i-hydrolyze yakhe i-acrylic acid ehambisanayo.
Ulwazi Lokuphepha
I-Trans-2,3-dimethacrylic acid iyinhlanganisela evamile yezinto eziphilayo, futhi imininingwane yayo yokuphepha imi kanje:
1. Ubuthi: I-trans-2,3-dimethacrylic acid inobuthi obuthile futhi ingase ibangele ukucasuka nokulimala emzimbeni womuntu. Lapho usebenzisa noma uphatha lesi sakhi, kufanele kuthathwe izinyathelo ezifanele ukuze kugwenywe ukuthintana ngqo nesikhumba, amehlo, kanye nomgudu wokuphefumula.
2. Ingozi yomlilo: I-Trans-2,3-dimethacrylic acid iyinto evuthayo ekhiqiza umhwamuko ovuthayo emazingeni okushisa aphezulu. Lapho uphatha noma ugcina lesi sithako, gwema ukuvutha kanye namazinga okushisa aphezulu, futhi ugcine umoya omuhle.
3. Izidingo zesitoreji: i-trans-2,3-dimethacrylic acid kufanele igcinwe esitsheni esingangeni moya, kude nemithombo yomlilo nama-oxidants. Kufanele igcinwe yodwa ezintweni ezivuthayo, ama-oxidants, nama-asidi aqinile ukuze kugwenywe ukusabela ngengozi.
4. Impendulo Yesimo Esiphuthumayo: Uma kwenzeka kuchitheka noma ingozi, izinyathelo ezidingekayo eziphuthumayo kufanele zithathwe ngokushesha, njengokugqoka izinto zokuzivikela ezifanele, ukukhipha abantu ngokushesha, nokuvimbela izinto ukuthi zingangeni ezitanjeni noma emithonjeni yamanzi engaphansi komhlaba.
5. Ukuvikela ukuchayeka: Lapho uphatha i-trans-2,3-dimethacrylic acid, okokusebenza kokuzivikela okufana namagilavu okuvikela, izibuko, nezingubo zokuzivikela kufanele kugqokwe ukuze kuqinisekiswe ukuphepha kwesikhumba, amehlo, nendlela yokuphefumula.
6. Ukulahlwa kukadoti: Imfucuza i-trans-2,3-dimethacrylic acid kufanele ilahlwe ngendlela efanele ngokuhambisana nemithetho yendawo. Gwema ukulahla imfucuza endaweni yemvelo bese uyinikezela esikhungweni esikhethekile sokuhlanza imfucuza ukuze ilahlwe.
