Intshayelelo

I-δ-Octanolactone, eyaziwa ngokuba yi-caprolactone, i-organic compound. Lulwelo olungenambala ukuya kumthubi oluluthuthu olunevumba elifana nele-octanol. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-δ-octanololide:

 

Umgangatho:

- δ-Octanolactone lulwelo oluguquguqukayo olunyibilikayo emanzini kunye nezinyibilikisi ezininzi eziphilayo.

- Yikhompawundi engazinzanga enokuthi ichaphazeleke kwi-polymerization kunye ne-hydrolysis.

- Ine-viscosity ephantsi, uxinzelelo olusezantsi kunye nokumanzisa okuhle.

 

Sebenzisa:

- I-δ-Octanolactone isetyenziswa kuluhlu olubanzi lwezicelo, kubandakanywa ukuveliswa kweeplastiki, i-polymer synthesis, kunye neengubo zangaphandle.

- Ingasetyenziswa njengecandelo lezinto zokunyibilikisa, i-catalysts kunye ne-plasticizers.

- Kwintsimi yeepolymers, i-δ-octanol lactone ingasetyenziselwa ukulungiselela i-polycaprolactone (PCL) kunye nezinye iipolymers.

- Inokusetyenziswa kwakhona kwizixhobo zonyango, iingubo, i-adhesives, i-encapsulation materials, njl.

 

Indlela:

- δ-Octololide inokulungiswa nge-esterification ye-ε-caprolactone.

- Ukusabela ngokuqhelekileyo kuqhutyelwa phantsi kweemeko ezifanelekileyo zokusabela ngokusabela kwi-ε-caprolactone kunye ne-acid catalyst efana ne-methanesulfonic acid.

- Inkqubo yokulungiselela idinga ulawulo lobushushu bokuphendula kunye nexesha lokufumana imveliso ecocekileyo.

 

Ulwazi ngoKhuseleko:

- Inokucaphukisa ulusu, amehlo, kunye nendlela yokuphefumla kwaye kufuneka igwenywe xa ibanjwe.

- Ngexesha lokusetyenziswa kunye nokugcinwa, kuyimfuneko ukugcina indawo enomoya kwaye ugweme imithombo yomlilo kunye nokushisa okuphezulu.

- Xa ulahla inkunkuma, kufuneka iphathwe kwaye ilahlwe ngokuhambelana nemimiselo yendawo.
