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

Mawu Oyamba

δ-Octanolactone, wotchedwanso caprolactone, ndi organic pawiri. Ndi madzi achikasu otumbululuka opanda utoto okhala ndi fungo la octanol. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha δ-octanololide:

Ubwino:

- δ-Octanolactone ndi madzi osungunuka omwe amasungunuka m'madzi ndi zosungunulira zambiri.

- Ndi gulu losakhazikika lomwe limatha kupangidwa ndi polymerization ndi hydrolysis.

- Ili ndi mamasukidwe otsika, kutsika kwapamtunda komanso kunyowa kwabwino.

Gwiritsani ntchito:

- δ-Octanolactone imagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikiza kupanga mapulasitiki, kaphatikizidwe ka polima, ndi zokutira pamwamba.

- Itha kugwiritsidwa ntchito ngati chigawo cha solvents, catalysts ndi plasticizers.

- M'munda wa ma polima, δ-octanol lactone angagwiritsidwe ntchito pokonzekera polycaprolactone (PCL) ndi ma polima ena.

- Itha kugwiritsidwanso ntchito pazida zamankhwala, zokutira, zomatira, zida zomangira, ndi zina.

Njira:

- δ-Octololide ikhoza kukonzedwa ndi esterification ya ε-caprolactone.

- Zomwe zimachitika nthawi zambiri zimachitika pamikhalidwe yoyenera pochita ε-caprolactone ndi chothandizira asidi monga methanesulfonic acid.

- Njira yokonzekera imafuna kuwongolera kutentha ndi nthawi kuti mupeze chinthu choyera kwambiri.

Zambiri Zachitetezo:

- Ikhoza kukwiyitsa khungu, maso, ndi kupuma ndipo iyenera kupewedwa ikakhudza.

- Pogwiritsa ntchito ndi kusunga, m'pofunika kusunga malo abwino komanso kupewa magwero a moto ndi kutentha kwakukulu.

- Potaya zinyalala, ziyenera kusamaliridwa ndikutayidwa motsatira malamulo amderalo.
