trans-2,3-Dimethylacrylic aside CAS 80-59-1
ubuziranenge
Trans-2,3-dimethacrylic aside ni amazi atagira ibara. Ni acide kandi irashobora kubyifatamo kugirango ibe umunyu uhuye. Irashobora kwitwara cyane hamwe na ogisijeni mubushyuhe bwicyumba kandi irashobora guhita yaka. Irashobora kandi kwitwara hamwe nibyuma bimwe na bimwe kugirango ibe umunyu uhuye. Acide Trans-2,3-dimethacrylic ifite solubile nziza kandi irashobora gushonga mumazi no mumashanyarazi. Mu nganda, akenshi ikoreshwa nkurwego rwo hagati muguhuza ibinyabuzima kama, kandi birashobora no gukoreshwa mugutegura polymers zimwe na zimwe, plastiki, hamwe nububiko.
Gukoresha hamwe na synthesis
Acide Trans-2,3-dimethacrylic, izwi kandi nka methylisobutenic aside, ni aside ya karubonike ituzuye irimo amatsinda abiri ya methyl. Ifite intera nini ya porogaramu.
Trans-2,3-dimethacrylic aside ikoreshwa nka monomer muri synthesis ya polymers. Irashobora gukoporora hamwe nabandi ba monomers binyuze mumikorere ya polymerisiyonike yubusa, nka copolymerisation hamwe na acide acrylic na methyl acrylate kugirango ibone methylisopropyl methyl acrylate copolymer. Izi polimeri zifite imiterere myiza mumarangi, gutwikira, gufatira, nibindi, kandi bikoreshwa mukwongera ingaruka zibicuruzwa, kugabanya ubukonje, nibindi.
Icya kabiri, aside-2,3-dimethacrylic aside irashobora kandi gukoreshwa nkigihe cyingenzi muguhuza ibinyabuzima. Amatsinda yayo abiri ya methyl atanga urubuga rukora rwo kubyitwaramo, kandi ibintu bitandukanye kama bishobora gutegurwa nibindi bikorwa byo guhindura amatsinda. Kurugero, nukubyitwaramo amine cyangwa alcool, ibinyabuzima bikora biologiya, nkibikoresho bikura bikura, birashobora guhuzwa.
Uburyo bwa synthesis ya trans-2,3-dimethacrylic aside ikunze gutegurwa nigisubizo cya isobutylene hamwe na hydrata ya karubone monoic. Isobutylene ikorwa nicyuma cyiza cya peracide kugirango ibone aside methylisobutenic aside, hanyuma igahita ikoreshwa na chloride ya cuprous irenze urugero kugirango ikore umunyu wimbere, hanyuma igahinduka hamwe na alcool kuri hydrolyze kugirango ikore aside ihwanye na acrylic.
Amakuru yumutekano
Trans-2,3-dimethacrylic aside ni uruganda rusanzwe, kandi amakuru yumutekano ni aya akurikira:
1. Uburozi: trans-2,3-dimethacrylic aside ifite uburozi runaka kandi irashobora gutera uburakari no kwangiza umubiri wumuntu. Mugihe ukoresheje cyangwa ukoresha iki kigo, hagomba gufatwa ingamba zikwiye kugirango wirinde guhura nuruhu, amaso, hamwe nubuhumekero.
2. Ibyago byumuriro: Acide Trans-2,3-dimethacrylic ni ikintu cyaka umuriro gitanga imyuka yaka ubushyuhe bwinshi. Mugihe ukoresha cyangwa ubitse iyi compound, irinde gutwikwa nubushyuhe bwinshi, kandi ukomeze guhumeka neza.
3. Igomba kubikwa mu bwigunge butwikwa, okiside, na acide ikomeye kugirango birinde impanuka.
.
5. Kurinda imurikagurisha: Mugihe ukoresheje aside-transet-2,3-dimethacrylic, ibikoresho byo kurinda umuntu nka gants zo kurinda, amadarubindi, n imyenda ikingira bigomba kwambara kugirango umutekano wuruhu, amaso, ninzira zubuhumekero.
6. Kurandura imyanda: Acide trans-2,3-dimethacrylic aside igomba gutabwa neza hakurikijwe amategeko yaho. Irinde kujugunya imyanda mu bidukikije kandi uyishyikirize ikigo cyihariye cyo gutunganya imyanda.
