trans-2,3-Dimethylacrylic acid CAS 80-59-1
tayada
Trans-2,3-dimethacrylic acid waa dareere aan midab lahayn. Waa aashito waxayna la falgali kartaa saldhigyada si ay u sameeyaan milix u dhigma. Waxay si xoog leh ula falcelin kartaa ogsijiinta heerkulka qolka waxaana laga yaabaa inay si iskiis ah u gubato. Waxa kale oo ay la falgali kartaa biraha qaarkood si ay u sameeyaan cusbada birta u dhiganta. Trans-2,3-dimethacrylic acid waxay leedahay milmayn wanaagsan waxaana lagu milmi karaa biyaha iyo dareerayaasha organic. Warshadaha, waxaa inta badan loo isticmaalaa sidii dhexdhexaad ah ee isku dhafka ah ee xeryahooda organic, iyo sidoo kale waxaa loo isticmaali karaa diyaarinta ee polymers gaar ah, balaastikada, iyo dahaarka.
Isticmaalka iyo hababka isku dhafan
Trans-2,3-dimethacrylic acid, oo sidoo kale loo yaqaan methylisobutenic acid, waa karboksylic acid aan saturated ahayn oo ka kooban laba kooxood oo methyl ah. Waxay leedahay codsiyo badan oo kala duwan.
Trans-2,3-dimethacrylic acid waxaa loo isticmaalaa sidii monomer ah oo ka mid ah falgalka polymers. Waxaa lagu koobiyeeyay monomers kale iyada oo loo marayo falcelinta polymerization xagjirka ah ee bilaashka ah, sida kobolymerization leh acrylic acid iyo methyl acrylate si loo helo methylisopropyl methyl acrylate copolymer. Polymers-yadani waxay leeyihiin sifooyin wanaagsan oo rinji, dhejisyo, dhejisyo, iwm.
Marka labaad, trans-2,3-dimethacrylic acid sidoo kale waxaa loo isticmaali karaa dhexdhexaad muhiim ah oo ku saabsan isku-dhafka organic synthetic. Labadeeda kooxood ee methyl waxay bixiyaan goobta firfircoon ee falcelinta, iyo walxo dabiici ah oo kala duwan ayaa lagu diyaarin karaa falcelin beddelaad kooxeed oo dheeraad ah. Tusaale ahaan, adoo ka falcelinaya amines ama alkolada, xeryahooda bayooloji ahaan firfircoon, sida xakamaynta koritaanka dhirta, ayaa la isku dari karaa.
Habka isku-dhafka ah ee trans-2,3-dimethacrylic acid waxaa caadi ahaan diyaariya falcelinta isobutylene oo leh carbon monoic acid hydrate. Isobutylene waxaa lagu falceliyaa birta togan si loo helo methylisobutenic acid substrate, kaas oo ka dibna lagu falceliyo koloriin koob oo dheeraad ah si loo sameeyo cusbo gudaha ah, ka dibna waxaa lagu falceliyaa alkohol si ay hydrolyzed u sameyso acrylic acid u dhigma.
Macluumaadka Badbaadada
Trans-2,3-dimethacrylic acid waa unug dabiici ah oo caadi ah, macluumaadka badbaadadiisana waa sida soo socota:
1. Sumowga: trans-2,3-dimethacrylic acid waxa ay leedahay sun gaar ah waxaana laga yaabaa in ay keento xanaaq iyo dhaawac jidhka bini'aadamka ah. Marka la isticmaalayo ama la tacaalayo xaruntan, taxaddar ku habboon waa in la sameeyaa si looga fogaado taabashada tooska ah ee maqaarka, indhaha, iyo mareenka neefsashada.
2. Khatarta dabka: Trans-2,3-dimethacrylic acid waa walax gubanaysa oo soo saarta uumiga guban ee heerkul sare. Markaad la tacaalayso ama kaydinayso xaruntan, iska ilaali dabka iyo heerkulka sare, oo ilaali hawo wanaagsan.
3. Shuruudaha kaydinta: trans-2,3-dimethacrylic acid waa in lagu kaydiyaa weel aan hawo lahayn, kana fog ilaha dabka iyo oksidayaasha. Waa in lagu kaydiyaa meel gooni ah oo ka soocna gubashada, oksaydhiyeyaasha, iyo asiidhyada xooggan si looga fogaado falcelinta shilalka ah.
4. Jawaabta degdega ah: Haddii ay dhacdo daadasho ama shil, tallaabooyinka degdegga ah ee lagama maarmaanka ah waa in si degdeg ah loo qaado, sida xidhashada qalabka ilaalinta shakhsi ahaaneed ee habboon, daad-gureynta dadka si degdeg ah, iyo ka hortagga walxaha soo galaya bulaacada ama ilaha biyaha ee dhulka hoostiisa.
5. Ka hortagga soo-gaadhista: Markaad la tacaalayso trans-2,3-dimethacrylic acid, qalabka ilaalinta shakhsi ahaaneed sida galoofyada ilaalinta, muraayadaha, iyo dharka ilaalinta waa in la xidhaa si loo hubiyo badbaadada maqaarka, indhaha, iyo mareenka neefsiga.
6. Qashin qubka: Qashinka trans-2,3-dimethacrylic acid waa in si sax ah loo qubo si waafaqsan xeerarka deegaanka. Iska ilaali inaad qashinka ku shubto deegaanka dabiiciga ah oo ku wareeji goob gaar ah oo lagu daweeyo qashinka si loo qubo.
