Taw qhia
Dodecyl cawv, tseem hu ua dodecyl cawv los yog dococosanol, yog cov organic compound. Nws yog ib qho khoom, tsis muaj xim thiab tsis muaj ntxhiab nrog cov tshuaj tsw qab tshwj xeeb.
Dodecyl cawv muaj cov khoom nram qab no:
2. Insoluble hauv dej, tab sis soluble hauv organic solvents xws li ether thiab cawv.
3. Nws muaj kev ruaj ntseg zoo thiab tsis tshua muaj volatility.
4. Nws muaj cov khoom lubricating zoo thiab tuaj yeem siv los ua cov roj nplua nyeem.
Kev siv tseem ceeb ntawm dodecyl cawv muaj xws li hauv qab no:
1. Raws li cov roj nplua nyeem, nws yog siv rau lubrication ntawm cov khoom siv thiab tshuab.
2. Raws li cov khoom siv raw rau surfactants, nws tuaj yeem siv los npaj cov tshuaj detergents thiab detergents.
3. Ua ib qho hnyav thiab diluent rau dyes thiab inks.
4. Siv los ua cov khoom siv raw rau cov khoom siv hluavtaws, feem ntau siv hauv cov tshuaj tsw qab thiab tshuaj tsw qab.
Txoj kev npaj ntawm dodecyl cawv tuaj yeem ua ke los ntawm cov hauv qab no:
1. Hydroreduction ntawm stearate catalyzed los ntawm potassium hydroxide.
2. Los ntawm cov tshuaj tiv thaiv hydrogenation ntawm dodecene.
1. Txawm hais tias dodecyl cawv yog ib qho chaw muaj kev nyab xeeb, nws tseem yuav tsum tau muab kaw kom nruj thiab tsis txhob sib cuag nrog cov pa oxygen kom tiv thaiv oxidation.
2. Tsis txhob ua phem rau cov oxidants thiab acids uas muaj zog.
