I-Methylhydrogenhendecanedioate(CAS#3927-60-4)

Isingeniso

Kuyinhlanganisela yemvelo enefomula yamakhemikhali ethi CH3OOC(CH2)9COOCH3. Okulandelayo yincazelo yezakhiwo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha lwale nhlanganisela:

Imvelo:

-Ukubukeka: uketshezi olungenambala

-Indawo yokubilisa: Cishe ku-380 ℃

-Ukuminyana: mayelana ne-1.03g/cm³

-Ukunyibilika: Kuncibilika ku-ethanol, ether nakwezinye izinyibilikisi zemvelo

Sebenzisa:

-Ivame ukusetshenziswa njengendawo ephakathi ekuhlanganiseni kwamakhemikhali futhi isetshenziswa ekuhlanganiseni ezinye izinhlanganisela eziphilayo.

-Ingasetshenziswa futhi njengesivikelo noma isibulala-zinambuzane.

Indlela:

-noma ingalungiswa nge-esterification ye-diacid ne-methanol. Indlela eqondile yokwengeza i-undecanedioic acid ne-methanol ku-reactor, futhi wenze ukusabela kwe-esterification phambi kwe-catalyst. Ngemva kokuphothulwa kokusabela, umkhiqizo ohlosiwe watholwa ngokusebenza kwe-distillation kanye nokuhlanza.

Ulwazi Lokuphepha:

-Iyacika futhi ingase ibangele ukucasuka emehlweni nasesikhumbeni. Kufanele kuqashelwe izinyathelo zokuzivikela ngesikhathi sokuphatha nokusebenzisa, njengokugqoka izibuko zokuzivikela, amagilavu ​​nezingubo zokuzivikela.

-Gwema ukuthintana nama-oxidants aqinile nama-acids aqinile ukuze ugweme ukusabela okuyingozi.

-Lapho ugcina, gcina uphawu endaweni eyomile, emnyama futhi engenawo umoya.
