trans-2,3-Dimethylacrylic acid CAS 80-59-1
quality
Trans-2,3-dimethacrylic acid imvura isina ruvara. Iyo ine acidic uye inogona kuita nemabhesi kuti igadzire iwo anoenderana nemunyu. Inogona kuita zvechisimba neokisijeni patembiricha yekamuri uye inogona kungopisa. Inogonawo kuita nemamwe simbi kuti igadzire munyu wesimbi unoenderana. Trans-2,3-dimethacrylic acid ine yakanaka solubility uye inogona kunyungudika mumvura uye organic solvents. Muindasitiri, inowanzoshandiswa senge yepakati mukugadzirwa kwe organic komisheni, uye inogona zvakare kushandiswa mukugadzirira mamwe mapolymer, mapurasitiki, uye machira.
Kushandisa uye synthesis nzira
Trans-2,3-dimethacrylic acid, inozivikanwawo semethylisobutenic acid, is unsaturated carboxylic acid ine mapoka maviri emethyl. Iine huwandu hwakawanda hwekushandisa.
Trans-2,3-dimethacrylic acid inoshandiswa semonomer mukugadzirwa kwemapolymers. Inogona kubatanidzwa nemamwe mamonmers kuburikidza nemahara radical polymerization reaction, senge copolymerization ine acrylic asidhi uye methyl acrylate kuwana methylisopropyl methyl acrylate copolymer. Aya mapolymer ane zvinhu zvakanaka mupendi, machira, anonamira, nezvimwewo, uye anoshandiswa kuwedzera kupikisa kwezvigadzirwa, kuderedza viscosity, nezvimwe.
Chechipiri, trans-2,3-dimethacrylic acid inogona zvakare kushandiswa seyakakosha yepakati mukugadzira organic synthesis. Iwo maviri methyl mapoka anopa iyo inoshanda saiti yekuita, uye akasiyana organic zvinhu anogona kugadzirwa nemamwe anoshanda eboka shanduko maitiro. Semuenzaniso, nekuita nayo nemaamine kana doro, biologically inoshanda makomisheni, senge chirimwa kukura regulators, anogona kugadzirwa.
Iyo synthesis nzira ye trans-2,3-dimethacrylic acid inowanzo gadzirirwa nekuita kwe isobutylene ine kabhoni monoic acid hydrate. Isobutylene inobatwa neperacid positive iron kuti iwane substrate methylisobutenic acid, iyo inobva yaitwa nekapurous chloride yakawandisa kuti igadzire munyu wemukati, uye yobva yaita nedoro kuti hydrolyze iite inowirirana acrylic acid.
Safety Information
Trans-2,3-dimethacrylic acid yakajairika organic compound, uye ruzivo rwayo rwekuchengetedza ndeichi:
1. Toxicity: trans-2,3-dimethacrylic acid ine humwe huturu uye inogona kukonzera kushatirwa uye kukanganisa kumuviri wemunhu. Paunenge uchishandisa kana kubata iyi komisheni, matanho akakodzera anofanirwa kutorwa kudzivirira kubata zvakananga neganda, maziso, uye nzira yekufema.
2. Moto wengozi: Trans-2,3-dimethacrylic acid chinhu chinopisa chinobudisa mhute dzinopisa pakupisa kukuru. Pakubata kana kuchengeta musanganiswa uyu, dzivirira kupisa uye kupisa kwakanyanya, uye chengetedza mhepo yakanaka.
3. Kuchengetedza zvinodiwa: trans-2,3-dimethacrylic acid inofanira kuchengetwa mumudziyo usina mhepo, kure nemoto uye oxidants. Inofanirwa kuchengetwa iri yega kubva kune zvinopisa, oxidants, uye yakasimba asidhi kudzivirira kuita netsaona.
4. Mhinduro yechimbichimbi: Kana pakaitika kurasika kana kuti tsaona, matanho anodiwa ekukurumidzira anofanira kutorwa nokukurumidza, akadai sokupfeka midziyo yokuzvidzivirira nayo yakafanira, kubudisa vanhu nokukurumidza, uye kudzivirira zvinhu kupinda mupombi dzetsvina kana kuti mumanyuko emvura ari pasi pevhu.
5. Kudzivirira kuratidzwa: Paunenge uchibata trans-2,3-dimethacrylic acid, midziyo yekudzivirira yega semagirovhosi ekudzivirira, magirovhosi, uye zvipfeko zvekudzivirira zvinofanirwa kupfekwa kuve nechokwadi chekuchengetedzwa kweganda, maziso, uye nzira yekufema.
6. Kurasa tsvina: Waste trans-2,3-dimethacrylic acid inofanira kuraswa zvakakodzera maererano nemitemo yemunharaunda. Dzivisa kurasira tsvina munzvimbo yakasikwa uye woiendesa kunzvimbo inoraswa tsvina.
