Intshayelelo
I-2-Methyl-2-pentenic acid, eyaziwa ngokuba yi-butenedic acid, i-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi olukhuselekileyo lwe-2-methyl-2-pentenoic acid:
Umgangatho:
- 2-Methyl-2-pentenoic acid ngulwelo olungenambala ukuya kumthubi oluluthuthu kunye nevumba elifana nesiqhamo.
- I-2-Methyl-2-pentenoic acid iyanyibilika emanzini kunye nezinyibilikisi eziphilayo ezifana ne-alcohol kunye ne-ethers.
- Yikhompawundi ezinzileyo engatshiyo ngokuzenzekelayo okanye iziqhumise ngokwazo kumaqondo obushushu aqhelekileyo kunye noxinzelelo.
Sebenzisa:
- I-2-Methyl-2-pentenoic acid isetyenziswa ngokuyintloko ekulungiseleleni iipolymers eziphezulu zokusebenza ezifana neengubo ezikhethekileyo, i-adhesives, kunye ne-sealants.
- Yinto ebalulekileyo ye-monomer yesibini enokuthi ilungiswe yi-polymerization ye-butenic acid copolymers.
Indlela:
- I-2-Methyl-2-pentenoic acid inokulungiswa nge-asidi-catalyzed add of cyclohexene.
- I-Dimethyllithium kunye ne-cyclohexene ziphendulwa ukufumana i-2-methyl-1-cyclohexenylmethyllithium, kwaye emva koko i-hydrolyzed kunye ne-acidified ukufumana i-2-methyl-2-pentenoic acid.
Ulwazi ngoKhuseleko:
- I-2-Methyl-2-pentenoic acid yinto ephazamisayo enokuthi ikhuphe ulusu kunye namehlo, kunye nezilumkiso eziyimfuneko ezifana nokunxiba iiglavu zokukhusela kunye nezibuko ezifunekayo ngexesha lokusetyenziswa.
- Ayizinzile ekukhanyeni kunye nokushisa okuphezulu, kunye neempendulo ze-polymerization zingenzeka, ngoko ukubonakaliswa kwexesha elide kwilanga okanye ukugcinwa kumaqondo aphezulu kufuneka kugwenywe.
- Ngexesha lokuphatha kunye nokugcinwa, kufuneka kugcinwe kude nezinto ezinokutsha kunye ne-oxidizing agents ukukhusela umngcipheko womlilo okanye ukuqhuma.
- Xa uphatha i-2-methyl-2-pentenoic acid, iiprotokholi ezifanelekileyo zokulinga kunye nezikhokelo zokusebenza ezikhuselekileyo kufuneka zilandelwe. Kwimeko yengozi, amanyathelo angxamisekileyo afanelekileyo kufuneka athathwe ngokukhawuleza kwaye uncedo lwezonyango lwengcali kufuneka lufunwe ngokukhawuleza.
