trans-2,3-Dimethylacrylic acid CAS 80-59-1
umgangatho
Trans-2,3-dimethacrylic acid lulwelo olungenambala. I-acidic kwaye inokusabela kunye neziseko ukwenza iityuwa ezihambelanayo. Inokusabela ngobundlongondlongo ngeoksijini kwiqondo lobushushu begumbi kwaye isenokuvutha ngokuzenzekelayo. Isenokusabela ngezinye iintsimbi ukwenza iityuwa zentsimbi ezihambelanayo. I-Trans-2,3-dimethacrylic acid ine-solubility efanelekileyo kwaye inokunyibilika emanzini kunye nezinyibilikisi eziphilayo. Kwimizi-mveliso, ihlala isetyenziswa njengendawo ephakathi kwi-synthesis ye-organic compounds, kwaye inokusetyenziswa ekulungiseleleni iipolymers ezithile, iiplastiki, kunye neengubo.
Ukusetyenziswa kunye neendlela zokudibanisa
I-Trans-2,3-dimethacrylic acid, eyaziwa ngokuba yi-methylisobutenic acid, yi-unsaturated carboxylic acid equlethe amaqela amabini e-methyl. Inoluhlu olubanzi lwezicelo.
I-Trans-2,3-dimethacrylic acid isetyenziswa njenge-monomer kwi-synthesis yeepolymers. Inokwenziwa icopolymerized kunye nezinye iimonomers ngokusebenzisa ifree radical polymerization reaction, efana ne-copolymerization nge-acrylic acid kunye ne-methyl acrylate ukufumana i-methylisopropyl methyl acrylate copolymer. Ezi polymers zineepropati ezintle kwiipende, iingubo, i-adhesives, njl., kwaye zisetyenziselwa ukunyusa ukuchasana kwempembelelo yeemveliso, ukunciphisa i-viscosity, njl.
Okwesibini, i-trans-2,3-dimethacrylic acid ingasetyenziselwa njengento ebalulekileyo ephakathi kwi-synthetic organic synthesis. Amaqela ayo amabini e-methyl anika indawo esebenzayo yokusabela, kunye neentlobo ezahlukeneyo zezinto eziphilayo zingalungiselelwa ngokuqhubekayo ukuguqulwa kweqela elisebenzayo. Ngokomzekelo, ngokusabela nge-amines okanye i-alcohols, iikhompawundi ezisebenzayo ze-biologically, ezifana nabalawuli bokukhula kwezityalo, zingenziwa.
Indlela yokudibanisa ye-trans-2,3-dimethacrylic acid idla ngokulungiswa ngokusabela kwe-isobutylene kunye ne-carbon monoic acid hydrate. I-Isobutylene iphendulwa nge-peracid positive iron ukuze ifumane i-substrate methylisobutenic acid, ethi emva koko iphendule nge-cuprous chloride egqithisileyo ukwenza iityuwa zangaphakathi, kwaye emva koko isabela ngotywala kwi-hydrolyze ukwenza i-acrylic acid ehambelanayo.
Ulwazi ngoKhuseleko
I-Trans-2,3-dimethacrylic acid yinto eqhelekileyo ephilayo, kwaye ulwazi lwayo lokhuseleko luhamba ngolu hlobo lulandelayo:
1. Ubutyhefu: i-trans-2,3-dimethacrylic acid inetyhefu ethile kwaye inokubangela ukucaphuka kunye nomonakalo kumzimba womntu. Xa usebenzisa okanye uphatha le khompawundi, kufuneka kuthathwe amanyathelo okhuseleko afanelekileyo ukuze kuthintelwe ukunxibelelana ngokuthe ngqo nolusu, amehlo, kunye nephecana lokuphefumla.
2. Ingozi yomlilo: I-Trans-2,3-dimethacrylic acid yinto enokutsha evelisa imiphunga enokutsha kumaqondo obushushu aphezulu. Xa uphethe okanye ugcina le khompawundi, kuphephe ukutshisa kunye namaqondo obushushu aphezulu, kwaye ugcine umoya omhle.
3. Iimfuno zokugcina: i-trans-2,3-dimethacrylic acid kufuneka igcinwe kwisitya esingangeni moya, kude nemithombo yomlilo kunye ne-oxidants. Kufuneka igcinwe yodwa kwizinto ezinokutsha, i-oxidants, kunye ne-acids ezomeleleyo ukunqanda ukusabela ngengozi.
4. Impendulo kaxakeka: Kwimeko yokuchitheka okanye ingozi, amanyathelo angxamisekileyo ayimfuneko afanele athatyathwe ngokukhawuleza, njengokunxiba izixhobo ezifanelekileyo zokuzikhusela, ukukhupha abantu ngokukhawuleza, kunye nokuthintela izinto ekungeneni kwimijelo ehambisa amanzi amdaka okanye kwimithombo yamanzi angaphantsi komhlaba.
5. Uthintelo lwe-Exposure: Xa uphethe i-trans-2,3-dimethacrylic acid, izixhobo zokukhusela zomntu ezifana neeglavu zokukhusela, iiglavu, kunye nempahla yokukhusela kufuneka inxibe ukuqinisekisa ukhuseleko lwesikhumba, amehlo, kunye nephecana lokuphefumla.
6. Ukuchithwa kwenkunkuma: Inkunkuma ye-trans-2,3-dimethacrylic acid kufuneka ilahlwe ngokufanelekileyo ngokuhambelana nemimiselo yendawo. Kuphephe ukulahla inkunkuma kwindawo yendalo kwaye uyigqithisele kwiziko elikhethekileyo lokucocwa kwenkunkuma ukuze ilahlwe.
