Mawu Oyamba

Dodecane diols. Makhalidwe ake:

 

2. Mankhwala a mankhwala: Ndi mowa wamafuta, womwe ndi hydrophilic ndi lipophilic, ndipo ungagwiritsidwe ntchito ngati emulsifier ndi surfactant. Imakhala ndi ma cushioning, omwe amathandizira kuwongolera ndi kukhazikika kwa acid-base balance. Ma diol a Dodecane ndiwofunikanso zomangira, zosungunulira zamafakitale ndi mankhwala.

 

3. Njira yokonzekera: Kukonzekera kwa ma diol a dodecane nthawi zambiri kumapezeka ndi hydrododecane aldehyde reaction. Izi zimathandizira gawo lapansi la dodecanealdehyde ndi haidrojeni, pamaso pa chothandizira choyenera, kupanga ma diol a dodecane.

 

4. Chidziwitso chachitetezo: Ma diol a Dodecane ali ndi kawopsedwe kakang'ono, koma kusamala kumafunikirabe kuti agwire bwino. Pogwiritsa ntchito, kukhudzana ndi khungu ndi maso kuyenera kupewedwa kuti musapse mtima. Mukamwedwa mwangozi kapena kukhudzidwa, funsani thandizo lachipatala kapena funsani akatswiri mwamsanga. Pa nthawi yomweyo, pawiri ayenera kusungidwa bwino ndi kutaya, kupewa kukhudzana ndi okosijeni ndi combustible kupewa ngozi.
