5-Octanolide(CAS#698-76-0)

Isingeniso

I-δ-Octanolactone, eyaziwa nangokuthi i-caprolactone, iyinhlanganisela yezinto eziphilayo. Iwuketshezi oluphuzi ukuya kokuphaphathekile olunephunga eliyingqayizivele le-octanol. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-δ-octanololide:

Ikhwalithi:

- I-δ-Octanolactone iwuketshezi olushintshashintshayo oluncibilika emanzini kanye nezincibilikisi eziningi eziphilayo.

- Kuyinhlanganisela engazinzile engase ibe ne-polymerization kanye ne-hydrolysis.

- Ine-viscosity ephansi, i-low surface tension kanye nokumanzisa okuhle.

Sebenzisa:

- I-δ-Octanolactone isetshenziswa kuhlelo olubanzi lwezinhlelo zokusebenza, okuhlanganisa ukukhiqizwa kwamapulasitiki, ukuhlanganiswa kwe-polymer, nama-surface coatings.

- Ingasetshenziswa njengengxenye yama-solvents, ama-catalysts nama-plasticizers.

- Emkhakheni wama-polymers, i-δ-octanol lactone ingasetshenziswa ukulungisa i-polycaprolactone (PCL) namanye ama-polymer.

- Ingasetshenziswa futhi kumishini yezokwelapha, i-coatings, i-adhesives, i-encapsulation materials, njll.

Indlela:

- I-δ-Octololide ingalungiswa nge-esterification ye-ε-caprolactone.

- Ukusabela ngokuvamile kwenziwa ngaphansi kwezimo ezifanele zokusabela ngokusabela i-ε-caprolactone nge-acid catalyst efana ne-methanesulfonic acid.

- Inqubo yokulungiselela idinga ukulawula izinga lokushisa lokusabela kanye nesikhathi sokuthola umkhiqizo ohlanzekile kakhulu.

Ulwazi Lokuphepha:

- Kungase kucasule isikhumba, amehlo, nokuphefumula futhi kufanele kugwenywe lapho kuthintwa.

- Ngesikhathi sokusetshenziswa nokugcinwa, kuyadingeka ukugcina indawo enomoya omuhle futhi ugweme imithombo yomlilo kanye nokushisa okuphezulu.

- Uma kulahlwa imfucuza, kufanele iphathwe futhi ilahlwe ngokuhambisana nemithetho yendawo.
