Nhanganyaya
Dimethyl azelaic acid (inozivikanwawo seDioctyl adipate, DOA) inowanzoitika organic compound. Inotevera sumo kune hunhu hwayo, kushandiswa, nzira dzekugadzira uye ruzivo rwekuchengetedza:
Hunhu:
- Chitarisiko: isina ruvara kune yero mvura
- Solubility: soluble mu organic solvents, zvishoma soluble mumvura
- Refractive index: approx. 1.443-1.449
Shandisa:
- Dimethyl azelarate inonyanya kushandiswa seplasticizer, ine yakanaka plasticity uye inotonhora kuramba, uye inogona kuwedzera kupfava uye kutonhora kuramba kwepurasitiki.
- Inowanzoshandiswa mukugadzira polyvinyl chloride (PVC) mapurasitiki, synthetic rubber, synthetic resins, nezvimwewo, kuvandudza plastiki yavo uye simba.
- Dimethyl azelaate inogona zvakare kushandiswa semafuta, nyoro uye antifreeze, pakati pezvimwe zvinhu.
Nzira:
Dimethyl azelaic acid inowanzo gadzirirwa ne esterification reaction seinotevera:
1. React nonanediol ine adipic acid.
2. Wedzera esterifying agents, zvakadai sesulfuric acid, sezvinokonzera mu esterification reaction.
3. Kuita kunoitwa pasi pe tembiricha yakakodzera uye mamiriro ekumanikidza kugadzira dimethyl azelaate.
4. Chigadzirwa chacho chinowedzera kucheneswa nekuderedza mvura, distillation uye mamwe matanho.
Zvekuchengetedza
- Dimethyl azelaic acid inofanirwa kuchengetedzwa pasi pemamiriro ekushandiswa akajairwa uye kudzivirira kusangana neganda nemeso.
- Pfeka midziyo yekudzivirira yakakodzera, kusanganisira yekudzivirira yekufema uye magurovhosi ekudzivirira, kana akashandiswa.
- Kuchenjerera kunofanira kubhadharwa kune nzvimbo inofefetera zvakanaka panguva yekushanda kudzivirira inhalation kana kupinza netsaona.
- Panguva yekuchengetedza uye yekufambisa, zvinodikanwa kudzivirira kusangana neoxidants, acids uye zvimwe zvinhu kudzivirira njodzi dzine njodzi.
