Abstract. Octanol-dej muab faib piv piv piv ib qho kev faib coefficient yog qhov sib piv ntawm cov concentration ntawm ib yam khoom nyob rau hauv ib qho nruab nrab los yog theem (C 1) rau cov concentration hauv theem thib ob (C 2) thaum ob qhov kev xav tau ntawm qhov sib npaug; uas yog, muab faib coefficient =(C1/C2)equilhttps://www.sciencedirect.com › topics › partition-coefficient

yog txoj hauv kev tshaj plaws ntawm kev qhia txog lipophilicity ntawm ib qho kev sib xyaw, thiab nws txhais tau tias yog piv ntawm cov concentration ntawm cov kuab tshuaj nyob rau hauv cov dej-saturated octanolic theem rau nws cov concentration hauv octanol- saturated aqueous theem.
Puas yog octanol saturated?
Yog tias peb ntxiv octanol thiab dej rau hauv lub hwj, co nws lub zog thiab tom qab ntawd tos rau ob theem sib cais, qhov system yuav mus txog qhov sib npaug. Ob phase yuav sib koom ua ke nrog ib leeg, piv txwv li, octanol theem yuav muaj 20% dej thiab theem dej yuav muaj 8 x 10-3% octanol.
Yog octanol-dej soluble?
Kev sib koom ua ke ntawm dej thiab 1-octanol: thaum lub solubility ntawm octanol hauv dej tsawg heev, qhov sib npaug ntawm cov dej hauv octanol ntawm chav tsev kub tau tshaj tawm tias yog kwv yees li 5 pawg feem pua.
octanol-dej faib coefficient yog dab tsi?
Nws tseem hu ua n-octanol-dej muab faib piv. Kow ua haujlwm raws li ntsuas kev sib raug zoo ntawm lipophilicity (rog solubility) thiab hydrophilicity (dej solubility) ntawm ib yam khoom.
Vim li cas n octanol siv?
Kow thiab logKow: Lawv Lub ntsiab lus rau Kev Ntsuam Xyuas Kev Nyab Xeeb
Rau qhov laj thawj saum toj no, n-octanol / dej faib coefficient (Kow) yog siv ua kev tshuaj ntsuam xyuas bio-accumululation testQhov kev xav hauv qab no yog qhov kev nqus ntawm cov organic yog tsav los ntawm nws cov hydrophobicity.
