Intshayelelo

I-Ethyl palmitate. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-ethyl palmitate:

 

Umgangatho:

- Imbonakalo: I-Ethyl palmitate lulwelo olucacileyo olungenambala ukuya kumthubi.

- Ivumba: Inevumba elikhethekileyo.

- Ukunyibilika: I-Ethyl palmitate iyanyibilika kwii-alcohols, ii-ethers, izinyibilikisi ezinevumba elimnandi, kodwa ayinyibiliki emanzini.

 

Sebenzisa:

- Izicelo zemizi-mveliso: I-Ethyl palmitate ingasetyenziselwa njengezongezelelo zeplastiki, i-lubricant kunye ne-softener, phakathi kwezinye izinto.

 

Indlela:

I-Ethyl palmitate inokulungiswa ngokusabela kwe-acid palmitic kunye ne-ethanol. I-Acid catalysts, njenge-asidi ye-sulfuric, isoloko isetyenziselwa ukuququzelela i-esterification.

 

Ulwazi ngoKhuseleko:

- I-Ethyl palmitate yikhemikhali ekhuselekileyo ngokubanzi, kodwa iinkqubo zokhuseleko eziqhelekileyo zisafuna ukulandelwa. Kuphephe ukudibana nolusu, amehlo, kunye nepheshana lokuphefumla ukunqanda ukucaphuka okanye ukusabela ngokwanelisayo.

- Amanyathelo afanelekileyo okungenisa umoya kufuneka athathwe ngexesha lemveliso yemizi-mveliso kunye nokusetyenziswa ukuphepha ukuphefumla umphunga wayo.

- Xa kwenzeka ukungenwa ngengozi okanye ukudibana nochwepheshe bezonyango, funa unyango okanye udibane nochwepheshe ngokukhawuleza.
