trans-2,3-Dimethylacrylic acid CAS 80-59-1

khalidwe
Trans-2,3-dimethacrylic acid ndi madzi opanda mtundu. Ndi acidic ndipo imatha kuchitapo kanthu ndi zoyambira kupanga mchere wofananira. Imatha kuchita mwamphamvu ndi okosijeni kutentha kwa chipinda ndipo imatha kuyaka yokha. Imathanso kuchitapo kanthu ndi zitsulo zina kupanga mchere wachitsulo wofananira. Trans-2,3-dimethacrylic acid imakhala ndi kusungunuka kwabwino ndipo imatha kusungunuka m'madzi ndi zosungunulira organic. M'makampani, nthawi zambiri amagwiritsidwa ntchito ngati wapakatikati pakuphatikizika kwazinthu zachilengedwe, ndipo angagwiritsidwenso ntchito pokonza ma polima, mapulasitiki, ndi zokutira.

Ntchito ndi kaphatikizidwe njira
Trans-2,3-dimethacrylic acid, yomwe imadziwikanso kuti methylisobutenic acid, ndi unsaturated carboxylic acid yomwe ili ndi magulu awiri a methyl. Iwo ali osiyanasiyana ntchito.

Trans-2,3-dimethacrylic acid imagwiritsidwa ntchito ngati monomer mu kaphatikizidwe ka ma polima. Itha kukhala copolymerized ndi ma monomers ena kudzera mu free radical polymerization reaction, monga copolymerization ndi acrylic acid ndi methyl acrylate kuti mupeze methylisopropyl methyl acrylate copolymer. Ma polima awa ali ndi zinthu zabwino mu utoto, zokutira, zomatira, ndi zina zambiri, ndipo amagwiritsidwa ntchito kukulitsa kukana kwa zinthu, kuchepetsa kukhuthala, etc.

Kachiwiri, trans-2,3-dimethacrylic acid itha kugwiritsidwanso ntchito ngati gawo lapakati pakupanga organic synthesis. Magulu ake awiri a methyl amapereka malo ochitirapo kanthu, ndipo mitundu yosiyanasiyana ya zinthu zachilengedwe imatha kukonzedwa ndi machitidwe ena osinthika amagulu. Mwachitsanzo, pochita ndi ma amines kapena mowa, mankhwala opangidwa ndi biologically, monga olamulira kukula kwa zomera, akhoza kupangidwa.

Njira yophatikizira ya trans-2,3-dimethacrylic acid nthawi zambiri imakonzedwa ndi zomwe isobutylene ndi carbon monoic acid hydrate. Isobutylene imayendetsedwa ndi chitsulo cha peracid kuti ipeze gawo lapansi la methylisobutenic acid, lomwe limasinthidwa ndi cuprous chloride yochulukirapo kuti ipange mchere wamkati, ndiyeno imachita ndi mowa kuti ikhale hydrolyze kuti ipange acrylic acid.

Zambiri Zachitetezo
Trans-2,3-dimethacrylic acid ndi wamba organic pawiri, ndipo chitetezo chake ndi motere:

1. Kawopsedwe: trans-2,3-dimethacrylic acid ali ndi kawopsedwe kena ndipo angayambitse mkwiyo ndi kuwonongeka kwa thupi la munthu. Mukamagwiritsa ntchito mankhwalawa, muyenera kusamala kuti musakhudze khungu, maso, ndi kupuma.

2. Moto woopsa: Trans-2,3-dimethacrylic acid ndi chinthu choyaka chomwe chimapanga nthunzi yoyaka pa kutentha kwakukulu. Pogwira kapena kusunga chigawochi, pewani kuyatsa ndi kutentha kwambiri, ndipo sungani mpweya wabwino.

3. Zofunikira posungira: trans-2,3-dimethacrylic acid iyenera kusungidwa mu chidebe chopanda mpweya, kutali ndi magwero a moto ndi okosijeni. Iyenera kusungidwa payokha kuchokera ku zinthu zoyaka, zotulutsa okosijeni, ndi ma asidi amphamvu kupeŵa zochitika mwangozi.

4. Yankho ladzidzidzi: Pakatayikira kapena ngozi, njira zofunika zadzidzidzi ziyenera kuchitidwa mwamsanga, monga kuvala zida zodzitetezera zoyenera, kutulutsa anthu mofulumira, ndi kuletsa zinthu kulowa m’ngalande kapena m’madzi apansi panthaka.

5. Kupewa kuwonetseredwa: Pogwira trans-2,3-dimethacrylic acid, zida zodzitetezera monga magolovesi oteteza, magalasi, ndi zovala zodzitchinjiriza ziyenera kuvalidwa kuonetsetsa chitetezo cha khungu, maso, ndi kupuma.

6. Kutaya zinyalala: Zinyalala za trans-2,3-dimethacrylic acid ziyenera kutayidwa moyenera malinga ndi malamulo a m’deralo. Pewani kutaya zinyalala m'chilengedwe ndikuzipereka kumalo apadera osungira zinyalala kuti zikatayidwe.
