Taw qhia
Dodecane diols. Nws cov khoom:
2. Cov khoom siv tshuaj lom neeg: Nws yog cov dej cawv muaj roj, uas yog hydrophilic thiab lipophilic, thiab tuaj yeem siv ua emulsifier thiab surfactant. Nws muaj cov khoom cushioning, uas yog qhov tsim nyog rau kev tswj hwm thiab stabilizing acid-base tshuav nyiaj li cas. Dodecane diols kuj yog ib qho tseem ceeb ntawm cov khoom siv hauv tsev, cov kuab tshuaj thiab tshuaj lom neeg.
3. Txoj kev npaj: Kev npaj ntawm dodecane diols feem ntau tau los ntawm hydrododecane aldehyde cov tshuaj tiv thaiv. Cov tshuaj tiv thaiv no catalyzes lub substrate dodecanealdehyde nrog hydrogen, nyob rau hauv lub xub ntiag ntawm ib tug tsim nyog catalyst, tsim dodecane diols.
4. Cov ntaub ntawv kev nyab xeeb: Dodecane diols muaj toxicity tsawg, tab sis kev saib xyuas tseem yuav tsum tau ua kom muaj kev nyab xeeb. Thaum siv, kev sib cuag ntawm daim tawv nqaij thiab qhov muag yuav tsum zam kom tsis txhob muaj qhov khaus. Nyob rau hauv rooj plaub ntawm kev noj tshuaj los yog raug mob, nrhiav kev kho mob lossis nrhiav kev pabcuam sai. Nyob rau tib lub sijhawm, qhov sib xyaw yuav tsum tau muab khaws cia thiab pov tseg kom zoo, tsis txhob sib cuag nrog oxidants thiab combustibles kom tsis txhob muaj kev phom sij.
