I-Dimethyl subrate(CAS#1732-09-8)

Isingeniso

I-Dimethyl octanoate, enefomula yamakhemikhali ethi C10H18O4, eyaziwa nangokuthi i-DOP (i-Di-n-octyl phthalate), iwuketshezi olungenambala futhi olusobala. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-dimethyl octanoate:

Ikhwalithi:

- Ukubukeka: Uketshezi olungenambala noma oluphuzi.

- Ukuminyana: 1.014 g/mL ku-25 °C (lit.)

-Indawo yokuncibilika: -1.6°C

- Indawo yokubilisa: 268 °C (ekhanyayo)

- Ukunyibilika: I-Dimethyl octanoate iyancibilika kuzincibilikisi zemvelo, ezifana notshwala, ama-ether nama-aromatics, futhi ayincibiliki emanzini.

Sebenzisa:

- I-Dimethyl octanoate isetshenziswa kakhulu njengesengezo sepulasitiki futhi isetshenziswa kakhulu ekukhiqizeni imikhiqizo yepulasitiki efana ne-polyvinyl chloride (PVC). Ingakhuphula ipulasitiki kanye nokuguquguquka kwepulasitiki, ithuthukise ukucutshungulwa kanye nezakhiwo zomzimba.

- I-Dimethyl octanoate ibuye isetshenziswe ngokujwayelekile njengesincibilikisi kweminye imikhiqizo yamakhemikhali efana nezingubo zokunamathela, izinto zokunamathisela, oyinki, namakha.

Indlela:

- Indlela yokulungiselela ye-dimethyl octanoate ivamise ukutholwa ngokusabela kwe-esterification kusetshenziswa i-n-octane ne-phthalic acid njengezisetshenziswa zokusetshenziswa.

Ulwazi Lokuphepha:

- I-Dimethyl octanoate ibhekwa njengephephile ngaphansi kwezimo ezijwayelekile zokusetshenziswa.

- Ngenxa yokuntengantenga kwayo okuphansi, ibeka engcupheni encane yokuhogela umoya noma ukuchayeka kubantu. Nokho, emazingeni okushisa aphezulu, kungase kukhiqizwe intuthu enobuthi namagesi ayingozi.

- Ukuchayeka isikhathi eside nokuvamile kungaba yingozi empilweni, kungabangela ukuzwela kwesikhumba noma ukucasuka, futhi kungase kucasule izinhlelo zokuphefumula nezokugaya.

- Uma usebenzisa i-dimethyl octamate, thatha izinyathelo zokuphepha ezidingekayo, njengokugqoka amagilavu ​​okuzivikela kanye nezibuko, nokugcina umoya omuhle.

- Lapho ugcina futhi uphatha i-dimethyl octamate, gwema ukuthintana nemithombo yomlilo futhi ugweme ukuxubana nezimpahla eziyingozi njengama-oxidants nama-asidi aqinile.
