Mawu Oyamba

N-Tetradecacarbonic acid, yomwe imadziwikanso kuti butanedioic acid, ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha n-tedecade carbonic acid:

 

Ubwino:

- Orthotetradecafacic acid ndi woyera crystalline olimba.

- Ili ndi chikhalidwe chosanunkha.

- N-tetradec carbonate imasungunuka pang'ono m'madzi ndipo imakhala yabwino kusungunuka mu zosungunulira za organic.

 

Gwiritsani ntchito:

- N-Tetradera carbonate ingagwiritsidwe ntchito ngati mafuta otenthetsera kwambiri komanso pulasitiki ya guluu wa jellyfish.

- Itha kugwiritsidwanso ntchito pokonza zinthu zama mankhwala monga ma resin a polyester, inki ndi zowonjezera zapulasitiki.

- Orthotetradec carbonate itha kugwiritsidwanso ntchito ngati zopangira zonunkhiritsa.

 

Njira:

- Pali njira zosiyanasiyana zopangira n-tetraderic acid, imodzi mwa njira zomwe zimagwiritsidwa ntchito kwambiri ndi njira ya alkyd, ndiko kuti, transesterification reaction ya hexanediol ndi sebacic acid kuti apeze n-tetraderic acid.

 

Zambiri Zachitetezo:

- N-Tetradecacarbonic acid ndi organic pawiri ndipo njira zotetezera ziyenera kutsatiridwa zikagwiritsidwa ntchito ndikusungidwa.

- Ndi mankhwala otsika kawopsedwe omwe alibe vuto lililonse mthupi la munthu komanso chilengedwe pansi pamikhalidwe yogwiritsidwa ntchito.

- Komabe, ndikofunikira kupewa kukhudzana mwachindunji ndi n-tetradecacarbonic acid ndikupewa kutulutsa fumbi kapena yankho lake kuti mupewe kupsa mtima komwe kungachitike.

- Valani zida zoyenera zodzitetezera (PPE) monga magalavu a mankhwala, magalasi, ndi zovala zodzitchinjiriza pogwira.
