Zoo:

1,9-Nonanediol yog ib qho khoom nrog dawb crystals ntawm chav tsev kub. Nws muaj cov khoom tsis muaj xim, tsis muaj ntxhiab, thiab soluble hauv cov kuab tshuaj organic xws li dej, ether, thiab acetone. Nws yog ib qho tsis-volatile compound thiab muaj toxicity tsawg.

Siv:

1,9-Nonanediol muaj ntau daim ntawv thov hauv kev lag luam tshuaj. Nws tuaj yeem siv los ua cov kuab tshuaj thiab solubilizer, thiab tseem tuaj yeem siv rau hauv kev lag luam tshuaj, dyes, resins, coatings, plastics, thiab lwm yam lag luam. Nws muaj cov khoom zoo surfactant thiab tuaj yeem siv los ua emulsifier, tus neeg sawv cev ntub dej thiab stabilizer.

Txoj kev:

Muaj ntau txoj hauv kev los npaj 1,9-nonanediol, thiab ib qho ntawm cov kev siv feem ntau yog synthesis los ntawm hydrogenation cov tshuaj tiv thaiv ntawm nonanal. Nonanal reacts nrog hydrogen nyob rau hauv lub xub ntiag ntawm ib tug catalyst los tsim 1,9-nonanediol.

Cov ntaub ntawv kev nyab xeeb:

1,9-Nonanediol muaj toxicity tsawg thiab muaj kev nyab xeeb rau kev lag luam. Raws li cov khoom siv tshuaj, cov kev ceev faj txog kev nyab xeeb hauv qab no tseem yuav tsum tau sau tseg:

- Tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag. Thaum muaj kev sib cuag, yaug tam sim ntawd nrog dej ntau thiab nrog kws kho mob.

- Thaum siv, yuav tsum siv qhov cua zoo kom tsis txhob nqus cov pa los yog vapors.

- Thaum khaws cia thiab tuav, nws yuav tsum tau tiv thaiv los ntawm kev sib cuag nrog oxidants thiab muaj zog oxidizing tshuaj kom tsis txhob muaj hluav taws kub los yog tawg.

- Hnav cov khoom tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav, thiab khaub ncaws tiv thaiv thaum siv.
