Mawu Oyamba
Dimethylmalonic acid (yomwe imadziwikanso kuti succinic acid) ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha dimethylmalonic acid:
Ubwino:
- Maonekedwe: Dimethylmalonic acid nthawi zambiri imakhala yopanda mtundu wa crystalline kapena ufa woyera.
- Kusungunuka: Kusungunuka muzosungunulira wamba monga madzi, ethanol ndi ether.
Gwiritsani ntchito:
- Monga zopangira mafakitale: Itha kugwiritsidwa ntchito kupanga utomoni wa polyester, zosungunulira, zokutira ndi zomatira.
Njira:
- Njira yodziwika bwino yopangira dimethylmalonic acid imapezeka ndi hydroformylation ya ethylene additive. Sitepe yeniyeni ndi hydrogenate ethylene ndi formic asidi kupanga glycolic acid, ndiyeno kupitiriza kuchita esterification pakati glycolic asidi ndi formic asidi kupeza chomaliza mankhwala dimethylmalonic asidi.
Zambiri Zachitetezo:
- Dimethylmalonic acid ndi yopanda poizoni, komabe muyenera kusamala kutsatira njira zotetezeka zogwirira ntchito mu labotale komanso pamalo opangira.
- Pewani kutulutsa fumbi kapena kukhudza khungu ndi maso mukamagwiritsa ntchito, ndipo valani zida zoyenera zodzitetezera (monga magolovesi ndi magalasi).
- Mukakhudzana mwangozi, muzimutsuka malo omwe akhudzidwa nthawi yomweyo ndi madzi ambiri ndikupempha thandizo lachipatala ngati kuli kofunikira.
