Taw qhia
Alkylbenzenesulfonates (LAS) yog ib chav kawm ntawm alkyl aromatic compounds nrog cov tshuaj ntxuav tes zoo, kev ua haujlwm saum npoo av, thiab cov khoom ntub dej, sawv cev rau hom nonionic surfactant. Cov tebchaw no feem ntau yog siv los npaj cov tshuaj ntxuav tes, tshuaj ntxuav tes, ntaub softeners, thiab cov khoom tu tus kheej.
Cov yam ntxwv zoo
Cov qauv tshuaj ntawm alkylbenzenesulfonates muaj lub nplhaib benzene raws li niam txiv core. Cov saw alkyl txuas nrog lub nplhaib benzene ntawm ntau txoj haujlwm; pawg alkyl feem ntau yog los ntawm C10 txog C14. Qhov ntev ntawm cov saw alkyl cuam tshuam rau nws cov dej num thiab solubility.
Physicochemical Properties
Alkylbenzenesulfonates yog hydrophilic tebchaw, yog li tsim cov qauv micelle hauv dej, muab lawv cov dej ntws zoo heev thiab cov khoom ntub dej. Ib txhij, alkylbenzenesulfonates pom zoo dispersing, emulsifying, thiab detergency peev xwm, zoo tshem tawm stains xws li roj thiab protein.
Daim ntawv thov
Alkylbenzenesulfonates yog cov khoom siv feem ntau hauv cov tshuaj ntxuav tes, tshwj xeeb tshaj yog nyob rau hauv cov tshuaj ua kom cov tshuaj detergents. Tsis tas li ntawd, alkylbenzene sulfonates kuj tseem siv tau los ua cov organic surfactants hauv papermaking, luam ntawv thiab dyeing, inks, thiab tshuaj pleev ib ce.
Kev nyab xeeb tam sim no, tsis muaj kev tshawb fawb txog cov tshuaj lom ntawm alkylbenzene sulfonates. Txawm li cas los xij, lawv muaj qee qhov cuam tshuam rau hauv dej ecosystems thiab nyiam tuaj yeem yooj yim thiab biodegrade qeeb hauv ib puag ncig. Thaum siv thiab pov tseg, yuav tsum tau saib xyuas kom txo qis kev cuam tshuam ib puag ncig.
【Summary】
Alkylbenzene sulfonates, raws li cov chav kawm ntawm cov organic surfactants, muaj cov tshuaj ntxuav tes zoo, dispersion, thiab emulsification zog, thiab tau siv dav hauv cov tshuaj ua kom cov tshuaj detergents, tshuaj ntxuav, softeners, thiab cov khoom tu tus kheej. Thaum siv, yuav tsum tau ceev faj txog kev nyab xeeb, thiab kev cuam tshuam ib puag ncig yuav tsum raug txo kom tsawg.
