Mawu Oyamba

1,9-Nonanediol ndi diol yokhala ndi maatomu asanu ndi anayi a carbon. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha 1,9-nonanediol:

 

Ubwino:

1,9-Nonanediol ndi yolimba yokhala ndi makhiristo oyera kutentha kutentha. Lili ndi mphamvu zokhala zopanda mtundu, zopanda fungo, komanso kusungunuka mu zosungunulira za organic monga madzi, ether, ndi acetone. Ndi gulu losasunthika ndipo lili ndi kawopsedwe kakang'ono.

 

Gwiritsani ntchito:

1,9-Nonanediol ili ndi ntchito zambiri mumakampani opanga mankhwala. Itha kugwiritsidwa ntchito ngati zosungunulira ndi solubilizer, ndipo itha kugwiritsidwanso ntchito ngati mankhwala, utoto, utomoni, zokutira, mapulasitiki, ndi mafakitale ena. Lili ndi zinthu zabwino za surfactant ndipo zitha kugwiritsidwanso ntchito ngati emulsifier, chonyowetsa ndi stabilizer.

 

Njira:

Pali njira zingapo zokonzekera 1,9-nonanediol, ndipo imodzi mwa njira zomwe zimagwiritsidwa ntchito kwambiri ndi kaphatikizidwe kuchokera ku hydrogenation reaction ya nonanal. Nonanal imakhudzidwa ndi haidrojeni pamaso pa chothandizira kupanga 1,9-nonanediol.

 

Zambiri Zachitetezo:

1,9-Nonanediol ili ndi kawopsedwe kakang'ono ndipo ndi yotetezeka kugwiritsa ntchito mafakitale. Monga mankhwala, njira zodzitetezera zotsatirazi ziyenera kukumbukiridwa:

- Pewani kukhudza khungu ndi maso. Mukakhala kukhudzana, muzimutsuka nthawi yomweyo ndi madzi ambiri ndipo funsani dokotala.

- Pogwiritsa ntchito, mpweya wabwino uyenera kugwiritsidwa ntchito kuti usapumedwe ndi mpweya kapena nthunzi.

- Posunga ndikugwira, ziyenera kutetezedwa kuti zisakhudzidwe ndi ma okosijeni ndi zinthu zamphamvu zotulutsa okosijeni kuti zipewe moto kapena kuphulika.

- Valani zida zodzitetezera zoyenera monga magolovesi, magalasi, ndi zovala zodzitetezera mukamagwiritsa ntchito.
