trans-2,3-Dimethylacrylic acid CAS 80-59-1
boleng
Trans-2,3-dimethacrylic acid ke mokelikeli o se nang mebala. E na le asiti mme e khona ho sebetsana le metheo ho etsa matsoai a tšoanang. E ka itšoara ka matla ha e na le oksijene mochesong oa kamore 'me e ka 'na ea cha ka tšohanyetso. E ka boela ea itšoara ka litšepe tse ling ho etsa matsoai a tšepe a tsamaellanang. Trans-2,3-dimethacrylic acid e na le ho qhibiliha hamonate 'me e ka qhibiliha ka har'a metsi le lihlahisoa tsa tlhaho. Indastering, hangata e sebelisoa e le setsi sa ho kopanya metsoako ea lintho tse phelang, 'me e ka boela ea sebelisoa ha ho etsoa li-polymers, li-plastiki le liphahlo tse itseng.
Lisebelisoa le mekhoa ea ho kopanya
Trans-2,3-dimethacrylic acid, e tsejoang hape e le methylisobutenic acid, ke unsaturated carboxylic acid e nang le lihlopha tse peli tsa methyl. E na le mefuta e mengata ea likopo.
Trans-2,3-dimethacrylic acid e sebelisoa e le monoma ha ho etsoa lipolymers. E ka kopanngoa le li-monomers tse ling ka karabelo ea mahala ea polymerization, joalo ka copolymerization ka acrylic acid le methyl acrylate ho fumana methylisopropyl methyl acrylate copolymer. Li-polymers tsena li na le thepa e ntle ka lipente, liphahlo, likhomaretsi, joalo-joalo, 'me li sebelisetsoa ho eketsa ho hanyetsa ha lihlahisoa, ho fokotsa viscosity, joalo-joalo.
Taba ea bobeli, trans-2,3-dimethacrylic acid e ka boela ea sebelisoa e le setsi sa bohlokoa ho synthetic organic synthesis. Lihlopha tsa eona tse peli tsa methyl li fana ka sebaka se sebetsang bakeng sa karabelo, 'me mefuta e fapaneng ea lintho tse phelang e ka lokisoa ke karabelo e tsoelang pele ea phetoho ea sehlopha. Ka mohlala, ka ho e arabela ka li-amine kapa lino tse tahang, metsoako e sebetsang ea biologically, e kang balaoli ba kholo ea limela, e ka etsoa.
Mokhoa oa ho kopanya oa trans-2,3-dimethacrylic acid hangata o lokisoa ke karabelo ea isobutylene ka carbon monoic acid hydrate. Isobutylene e ts'oaroa ka tšepe e ntle ea peracid ho fumana substrate methylisobutenic acid, eo ka nako eo e arabelang ka ho fetelletseng ka cuprous chloride ho etsa matsoai a ka hare, ebe e arabela ka joala ho hydrolyze ho theha asiti e lumellanang ea acrylic.
Boitsebiso ba Tšireletseho
Trans-2,3-dimethacrylic acid ke motsoako o tloaelehileng oa lintho tse phelang, 'me tlhahisoleseding ea eona ea polokeho ke e latelang:
1. Chefo: Trans-2,3-dimethacrylic acid e na le chefo e itseng 'me e ka baka ho teneha le ho senya' mele oa motho. Ha ho sebelisoa kapa ho sebetsana le motsoako ona, ho lokela ho nkoa mehato e nepahetseng ho qoba ho kopana ka ho toba le letlalo, mahlo le tsela ea ho hema.
2. Kotsi ea mollo: Trans-2,3-dimethacrylic acid ke ntho e tukang e hlahisang mouoane o tukang mochesong o phahameng. Ha u tšoara kapa u boloka motsoako ona, qoba ho tuka le mocheso o phahameng, 'me u boloke moea o motle.
3. Litlhoko tsa polokelo: trans-2,3-dimethacrylic acid e lokela ho bolokoa ka setsing se se nang moea, hole le mehloli ea mollo le li-oxidants. E lokela ho bolokoa ka thoko ho lintho tse tukang, li-oxidants, le li-acid tse matla ho qoba ts'ebetso ea kotsi.
4. Karabelo ea Boemo ba Tšohanyetso: Ha ho ka tšolloa kapa ho e-ba le kotsi, mehato e hlokahalang ea tšohanyetso e lokela ho nkoa hang-hang, e kang ho roala thepa e loketseng ea ho itšireletsa, ho ntša batho ka potlako, le ho thibela lintho ho kena tsamaisong ea likhoerekhoere kapa mehloling ea metsi a ka tlas’a lefatše.
5. Thibelo ea ho pepeseha: Ha u tšoara trans-2,3-dimethacrylic acid, lisebelisoa tsa ho itšireletsa tse kang li-gloves tse sireletsang, likhalase le liaparo tse sireletsang li lokela ho apesoa ho netefatsa tšireletso ea letlalo, mahlo le tsela ea ho hema.
6. Ho lahla litšila: Litšila tsa trans-2,3-dimethacrylic acid li lokela ho lahloa ka nepo ho latela melao ea lehae. Qoba ho lahlela litšila tikolohong ea tlhaho 'me u li nehele setsing se khethehileng sa ho hloekisa litšila hore li lahloe.
