Qhov sib txawv tseem ceeb ntawm methacrylic acid thiab acrylic acid yog tias methacrylic acid molecule muaj ib pawg methyl txuas rau pawg alkene, whereas acrylic acid molecule tsis muaj lwm pawg txuas nrog alkene pawg.
Acrylic acid yog cov organic compound uas muaj ob pawg alkene thiab pawg carboxylic acid nyob rau hauv tib lub molecule. Methacrylic acid yog derivative ntawm acrylic acid; nws muaj ib pawg methyl txuas nrog cov qauv acrylic acid.
YMethacrylic Acid yog dab tsi?
Methacrylic acid yog cov organic compound uas muaj cov tshuaj formula C4H6O2Peb tuaj yeem pom methacrylic acid li MAA. Nws yog xim tsis muaj xim, kua nplaum. Cov tshuaj no poob rau hauv qeb ntawm carboxylic acids, thiab nws muaj ntxhiab tsw ntxhiab. Peb tuaj yeem yaj methacrylic acid hauv dej sov thiab; nws yog miscible nrog feem ntau cov kuab tshuaj organic. Nyob rau hauv kev lag luam nplai, peb tuaj yeem tsim cov kua qaub no hauv cov nplai loj los siv ua ntej rau esters ntawm methacrylic acid thiab polymer cov ntaub ntawv xws li polymethyl methacrylate (PMMA).
Daim duab 01: Cov qauv ntawm Methacrylic Acid
Thaum xav txog kev tsim cov methacrylic acid, peb tuaj yeem tsim nws los ntawm acetone cyanohydrin siv sulfuric acid. Ntawm no, cov kua qaub no hloov mus rau hauv methacrylamide sulfate. Cov khoom no tuaj yeem hydrolyzed rau hauv methacrylic acid. Tsis tas li ntawd, peb tuaj yeem npaj nws los ntawm decarboxylation ntawm itaconic acid, citraconic acid, mesaconic acid, thiab lwm yam. Ntxiv mus, methacrylic acid yog siv nyob rau hauv ib co ntsia thawv primers los pab acrylic rau tes ua raws li tus ntsia thawv daim hlau.
YAcrylic Acid yog dab tsi?
Acrylic acid yog cov organic compound uas muaj cov tshuaj formula C3H4O2 Nws yog qhov yooj yim tshaj plaws carboxylic acid nrog unsaturation (nws muaj ob daim ntawv cog lus nyob ib sab ntawm pawg carboxylic). Tsis zoo li methacrylic acid, cov molecule no tsis muaj methyl pawg txuas mus rau thaj tsam unsaturated ntawm cov molecule. Acrylic acid yog cov kua uas tsis muaj xim, thiab nws muaj cov yam ntxwv tsw ntxhiab tsw. Cov tshuaj no yog miscible nrog dej thiab yog soluble hauv organic solvents xws li cawv, ether thiab chloroform.
Daim duab 02: Cov qauv ntawm Acrylic Acid
Muaj ntau txoj hauv kev los tsim cov kua qaub acrylic. Txoj kev loj yog oxidation ntawm propylene. Ntawm no, peb tuaj yeem tau txais propylene los ntawm kev tsim cov ethylene thiab roj av. Txawm li cas los xij, propane yog qhov pheej yig dua li propylene; Yog li, peb tuaj yeem siv propane ua lwm txoj hauv kev.
Acrylic acid muaj qee qhov kev siv tseem ceeb. Piv txwv li, nws yog siv hauv kev lag luam xws li kev tsim cov ntaub qhwv, kev kho dej thiab kev lag luam textile. Feem ntau, qhov sib xyaw no yog ib qho tseem ceeb ntawm cov khoom siv polymer vim tias nws yooj yim tsim cov polymers nrog lwm cov monomers xws li acrylamides los ua homopolymers thiab copolymer.
Qhov txawv ntawm Methacrylic Acid thiab Acrylic Acid yog dab tsi?
Qhov sib txawv tseem ceeb ntawm methacrylic acid thiab acrylic acid yog tias methacrylic acid molecule muaj ib pawg methyl txuas rau pawg alkene, hos acrylic acid molecule tsis muaj lwm pawg txuas nrog alkene pawg. Ntxiv mus, methacrylic acid yog tsim los ntawm ib pawg methyl, ob daim ntawv cog lus thiab carboxylic pawg thaum acrylic acid yog tsim los ntawm ob daim ntawv cog lus thiab carboxylic pawg.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm methacrylic acid thiab acrylic acid.
Summary – Methacrylic Acid vs Acrylic Acid
Methacrylic acid yog ib qho derivative ntawm acrylic acid; nws muaj ib pawg methyl txuas nrog cov qauv acrylic acid. Qhov sib txawv tseem ceeb ntawm methacrylic acid thiab acrylic acid yog tias methacrylic acid molecule muaj ib pawg methyl txuas rau pawg alkene, hos acrylic acid molecule tsis muaj lwm pawg txuas nrog alkene pawg.
