Trans-2,3-dimethacrylic acid bụ mmiri mmiri na-enweghị agba. Ọ bụ acidic ma nwee ike meghachi omume na ntọala iji mepụta nnu kwekọrọ. Ọ nwere ike iji oxygen meghachi omume n'ike n'ime ụlọ okpomọkụ ma nwee ike ịgba ọkụ ozugbo. Ọ nwekwara ike iji ụfọdụ ọla meghachi omume iji mepụta nnu metal kwekọrọ. Trans-2,3-dimethacrylic acid nwere ezigbo solubility ma nwee ike igbari na mmiri na ihe mgbaze organic. N'ime ụlọ ọrụ, a na-ejikarị ya eme ihe dị ka etiti na njikọ nke ogige ndị dị ndụ, a pụkwara iji ya mee ihe na nkwadebe nke ụfọdụ polymers, plastik, na mkpuchi.
Na-eji na njikọ usoro
Trans-2,3-dimethacrylic acid, nke a makwaara dị ka methylisobutenic acid, bụ carboxylic acid na-adịghị edozi nke nwere otu methyl abụọ. Ọ nwere ọtụtụ ngwa ngwa.
A na-eji trans-2,3-dimethacrylic acid mee ihe dị ka monomer na njikọ nke polymers. Enwere ike ime ya na monomers ndị ọzọ site na mmeghachi omume polymerization efu, dị ka copolymerization na acrylic acid na methyl acrylate iji nweta methylisopropyl methyl acrylate copolymer. Ndị polymer ndị a nwere ihe dị mma na agba, mkpuchi, adhesives, wdg, a na-ejikwa ya mee ka mmegide mmetụta nke ngwaahịa, belata viscosity, wdg.
Nke abuo, trans-2,3-dimethacrylic acid nwekwara ike iji dị ka ihe dị mkpa etiti na sịntetik organic njikọ. Otu methyl ya abụọ na-enye saịtị na-arụsi ọrụ ike maka mmeghachi omume ahụ, na enwere ike ịkwadebe ihe dị iche iche nke organic site na mmeghachi omume ntụgharị nke otu ndị ọzọ na-arụ ọrụ. Dịka ọmụmaatụ, site na ịmeghachi ya na amines ma ọ bụ alcohols, enwere ike ịmepụta ogige ndị na-arụ ọrụ ndụ, dị ka ndị na-ahụ maka uto osisi.
A na-akwadokarị usoro njikọ nke trans-2,3-dimethacrylic acid site na mmeghachi omume nke isobutylene na carbon monoic acid hydrate. A na-emeghachi Isobutylene na peracid positive iron iji nweta mkpụrụ methylisobutenic acid, nke a na-emeghachi ya na ngafe cuprous chloride na-emepụta nnu dị n'ime, wee meghachi omume na mmanya na-aba n'anya hydrolyzed iji mepụta acrylic acid kwekọrọ.
Ozi nchekwa
Trans-2,3-dimethacrylic acid bụ ngwakọta organic nkịtị, yana ozi nchekwa ya bụ ndị a:
1. Nsi: trans-2,3-dimethacrylic acid nwere ụfọdụ nsí na nwere ike ime ka mgbakasị ahụ na imebi ahụ mmadụ. Mgbe ị na-eji ma ọ bụ na-ejikwa ngwa a, a ga-akpachapụ anya kwesịrị ekwesị iji zere mmekọahụ kpọmkwem na akpụkpọ ahụ, anya, na traktị iku ume.
2. Ihe ize ndụ ọkụ: Trans-2,3-dimethacrylic acid bụ ihe na-ere ọkụ nke na-emepụta vapors ọkụ na okpomọkụ dị elu. Mgbe ị na-ejikwa ma ọ bụ na-echekwa ogige a, zere mgbanye ọkụ na oke okpomọkụ, ma nọgide na-enwe ezigbo ikuku.
3. Ihe nchekwa chọrọ: trans-2,3-dimethacrylic acid kwesịrị ịchekwa n'ime akpa ikuku, pụọ na isi ọkụ na oxidants. Ekwesịrị ịchekwa ya na iche site na combustibles, oxidants, na acid siri ike iji zere mmeghachi omume mberede.
4. Nzaghachi mberede: Ọ bụrụ na mwụfu ma ọ bụ ihe mberede, a ga-eme ihe mberede dị mkpa ozugbo, dị ka iyi ngwá ọrụ nchedo onwe onye kwesịrị ekwesị, ịchụpụ ndị mmadụ ngwa ngwa, na igbochi ihe ndị na-abanye n'ọwa mmiri ma ọ bụ mmiri n'okpuru ala.
5. Mgbochi ihe ngosi: Mgbe ị na-eji trans-2,3-dimethacrylic acid, ngwá ọrụ nchebe onwe onye dị ka uwe mkpuchi, enyo, na uwe nchebe kwesịrị iyi iji hụ na nchekwa nke akpụkpọ ahụ, anya, na akụkụ iku ume.
6. Mkpofu mkpofu: A ga-ekpochapụ ihe mkpofu trans-2,3-dimethacrylic acid nke ọma dịka iwu obodo si dị. Zere ịkwanye ihe mkpofu na gburugburu ebe obibi ma nyefee ya n'ebe a na-edozi ihe mkpofu pụrụ iche maka mkpofu.
