Isingeniso

I-n-Tetradecacarbonic acid, eyaziwa nangokuthi i-butanedioic acid, iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-n-tedecade carbonic acid:

 

Ikhwalithi:

- I-Orthotetradecafacic acid iyi-crystalline solid solid.

- Inesici esingenaphunga.

- I-N-tetradec carbonate incibilika kancane emanzini futhi inokuncibilika okuhle kuzincibilikisi zemvelo.

 

Sebenzisa:

- I-N-Tetradera carbonate ingasetshenziswa njengesithambisi sezinga eliphezulu lokushisa kanye ne-plasticizer yeglue ye-jellyfish.

- Ingasetshenziswa futhi ekulungiseni imikhiqizo yamakhemikhali efana ne-polyester resins, oyinki kanye nezithasiselo zepulasitiki.

- I-Orthotetradec carbonate ingasetshenziswa futhi njengento eluhlaza yamakha okwenziwa.

 

Indlela:

- Kunezindlela ezihlukahlukene zokulungiselela i-n-tetraderic acid, enye yezindlela ezivame ukusetshenziswa yindlela ye-alkyd, okungukuthi, ukusabela kwe-transesterification ye-hexanediol ne-sebacic acid ukuthola i-n-tetraderic acid.

 

Ulwazi Lokuphepha:

- I-N-Tetradecacarbonic acid iyinhlanganisela evamile yezinto eziphilayo futhi izinqubo zokuphepha ezijwayelekile zidinga ukulandelwa lapho zisetshenziswa futhi zigcinwa.

- Kuyinhlanganisela enobuthi obuphansi engenawo umonakalo osobala emzimbeni womuntu kanye nemvelo ngaphansi kwezimo ezijwayelekile zokusetshenziswa.

- Kodwa-ke, kusadingeka ukugwema ukuthintana ngqo ne-n-tetradecacarbonic acid futhi ugweme ukuhogela uthuli lwayo noma isisombululo ukuze ugweme ukucasuka okungenzeka kanye nokungezwani komzimba.

- Gqoka izinto zokuzivikela ezifanele (i-PPE) njengamagilavu ​​amakhemikhali, izibuko, nezingubo zokuvikela amakhemikhali lapho ubamba.
